Chapter 31

A Hop, Skip, and a Time Jump

Part 1- Progress Report

One Week Before…..

Undyne and Gaine sat across from each other at the diner. Neither was really in the mood to order anything, so they sat with their glasses of water and a shared appetizer between them so it wouldn't look like they were loitering.

The entire time, Gaine noticed Undyne's dejected expression. Something must have happened during her meeting with the kid. She was being oddly quiet and couldn't seem to focus on any one thing.

"Undyne." Gaine said, trying to get her attention, "When you called this meeting, there was something about your voice that seemed off. You met up with Corbel, right? What happened?"

Undyne's frown remained plastered and unmoving and she let out breath after long breath and groan after frustrated groan.

"Aldrin . . . I think I have to bow out." Ugh, even muttering it was a pain. It felt like she'd just been beaten down in battle and forced to admit defeat.

It felt disgusting.

"Wait, what!?" Gaine asked in complete surprise, "How . . . Why!?"

Undyne sighed once again, trying to collect herself before she spoke. "Tonight, I had a little conversation with Puff . . . I mean . . . With Corbel about my encounter with Sans. Needless to say, he wasn't too pleased with what happened. He . . . Threatened to terminate our friendship if I didn't stand down."

"So he chose Serif over his childhood friend . . ." Gaine mused, thinking the implications over before continuing, "And you're just going to surrender? That doesn't sound like you at all!"

For a short moment, Undyne flashed a large yellow eye up at Gaine before diverting her gaze once again.

"I . . . Can't risk losing him."

"You realize that that is exactly what will happen if you leave him be, don't you?"

"And now you're telling me how to handle my friends!?" Undyne bit back. "You were the one who said I had the right to refuse, right!?"

"I did. But listen, Undyne! I get it, you're scared."

"Don't assume you understand how I feel!"

Gaine gripped both hands on his glass of water, holding tightly. He looked down to the table, eyeing the untouched appetizer between them.

"But I do understand. Listen, I don't want you to jeopardize your friendship either. Losing your friends is the worst kind of pain. Like a bad break up, it can scar you for life. And if I can spare you that pain, I will. But, will you consider staying with me? At least for the time being? You've been instrumental to this investigation and now, I can't imagine doing this without you."

"You don't say." Undyne muttered, unconvinced. "And if I decline?"

"Then . . . I just don't know. Before, I would have said that I would find another way. Now, I have to say that . . . You've really become . . . Quite important to my plans."

Undyne looked back up toward Gaine who had since looked back up and was now giving her a nearly pleading expression. Her frown became studious. "Why? And just what are your 'plans' anyway? Were you ever going to divulge that info?"

Gaine hummed, "I suppose you do have a point. I can't expect you to be my partner in this endeavor if I don't fill you in." His sly smile began to make a reappearance, slowly making its way across his face. "Right now, I admit, it's still in the beginning stages, but I plan to save the Underground and help Doctor Gaster break the barrier to release all Monsters from this Hell."

"Great. Your mission statement. And this has what to do with the punk?"

"I'm absolutely sure now that he knows more about what's going on in that area than he's letting on. If my previous suspicion is accurate and he's working for someone else besides the Doctor, he'll have that information as well. It could even be details on how to break the barrier. I plan on getting that information out of him no matter what. The recon you've done so far has really helped to shed some light on the situation at hand. You've helped to verify some major suspicions and really give insight on some-"

"Right! I've been doing you favor after favor! I lost my fucking eye doing you favors! If I'm gonna stick around, who's to say something won't fuck up and I lose my best friend too? If I stick around, you're gonna have to give me one Hell of a good reason!"

Gaine hesitated for a second while he connected his thoughts. He gripped the water glass tighter, his claws tapping musical notes on the chilled surface.

"You're right." He said, the tone of his voice significantly softer, "You're absolutely right. I apologize, Undyne. It's true that you've sacrificed more than the average person would and with little retribution. I won't ask you to give any more than you already have. But if this really is where we split ways, at the very least, I can fill you in on my analysis of the situation thus far."

Undyne crossed her arms and leaned back in her seat, still retaining eye contact with the Cat. "I'm listening."

"Right. So you know that Serif and the doctor have been at ends ever since the incident with the cave in, right?"

"Of course. He's kind of the whole reason Corbel nearly died. Of course he's not gonna be his favorite guy in the world."

"It's more than that." Gaine grinned, "I think Gaster's starting to get more suspicious of Serif as well. He's been keeping closer tabs on him now than before. Asking for more frequent reports, discreetly asking the rest of us about our interactions with him. He's digging. And I'm going to help him find dirt. So, far, I haven't found any hard evidence suggesting that Serif is passing along intel to a third party, but it's only a matter of time before we shake him. I plan on using the info you've gathered to corner him. Bait him into talking."

He didn't mention the other aspect to the plan. Knowing how Undyne felt about Corbel, he knew it wouldn't be wise to mention using him as said bait. Based on what Undyne told him about her fight with Serif, however, as well as what he witnessed from the cave-in, Serif would do anything if it meant protecting Corbel. He was Serif's source of strength and his motivation to spring into action. If he could use that to his advantage . . . .

He didn't know how yet, but he knew that it would work. And not only on Serif. It could work on Undyne too.

"There's something really wrong here." Gaine continued, "He still introduces himself as a Skeleton. And you've already proven that that isn't accurate. After all, Skeletons don't bleed."

"We've already established this. Have you figured out what it means yet?" Undyne snapped, becoming more impatient.

"It means that there's definitely something about himself that he's hiding. From us, from Gaster, and from Corbel. He knows he's not a Skeleton and yet, he's lying about it and using it as a way in with actual Skeletons. Why? What purpose is he serving?"

"That's what we've been looking for this whole time, isn't it. So far, we've made zero progress."

"It's true it's been a slow investigation, but I believe we are on the verge of a breakthrough. I will find out what Serif is and why he's hiding it from even his 'boyfriend'. If need be, I will help you save Corbel from him."

Undyne eyed Gaine, keeping her arms crossed.

"You're worried that Corbel is so caught in with Serif that he's blind to the danger he's truly in. I'm certain Gaster worries about the same thing. I will help to put both of you at ease. I will expose Serif. I will take him down. You have my word. All I ask is that, when the time comes, you have my back. For now, if you feel that you need to back down in order to salvage your friendship, then I have no power to stop you. Lay low. Don't get actively involved, but keep your eyes open for anything else out of the ordinary. That is my request."

He released his water glass and held his hand out toward Undyne as an offer. His voice sounded composed, but Undyne could sense the slight panic just behind his eyes.

"Will you continue to be my partner, Undyne?"

It took a few more moments of Undyne sizing Gaine up and down. He really was gung-ho about this, wasn't he? Why was he so adamant?

Eventually, she uncrossed her arms and reached out to take the offer.

"You know, stealth was never really my strong suit." She admitted, "I'm more of a front lines kind of girl. But, I guess, I could always use the practice. But if you're taking the lead here, you have to play the part. Don't you dare let that jerk hurt Puffball again. Got it!"

Gaine held firmly onto Undyne's hand, never once breaking eye contact with her. He adjusted his grip, stroking the top of her hand with his thumb as he took her fingers, encapsulating them, almost as if he was about to lift them to kiss. A gentleman to a lady.

"Understood." He smirked.

Part 2- Commencement

One Month Later . . .

The time seemed to fly by after the day Corbel came to speak with his father. The weeks all began to mush together in a hastily constructed montage of events. Invitations had been verbally delivered, exams had been taken, plans had been set in motion, the cap and gown had been purchased, and his time was upon him.

He stood in the living room to his dorms with the square-topped hat held loosely in his hands and the gown on, but unzipped over his suit. He still couldn't believe this was happening. He'd actually made it through, despite setback after setback. Hardship after hardship. It took effort and sacrifice, hard work, and determination, but in the end, he made it.

Graduation day.

Behind him, the door creaked open and another monster shuffled out. Surprisingly, he looked a lot more alert than Corbel had ever seen him. There was a certain sheen to his scales that was never there before and his eyes looked brighter than ever.

"Hey, Teri!" Corbel called back to his roommate as the Reptile made his way out into the living room as well.

"Corbel! Congratulations, man!"

"Congrats yourself! Marketing, huh? Those classes seemed really tough. Plus working full-time. I'm glad you made it out in one piece!"

"Heh, you're one to talk." Teri teased, doing his gown up and making sure there was enough room for his tail, "If anyone was in danger of not making it in one piece, it was you. I'm just . . . I'm really glad you were able to finish your degree and, of course, you didn't . . . You know . . . Die."

Corbel stalled for a moment, thinking it over. So, the incident even had an effect on Teri? Somehow, it didn't even occur to him that he would've cared at all.

He held an arm out toward his roommate and met him in a side hug.

"Thanks." He answered simply. "You know, I'm proud of us. We really made it, huh?"

"Yup." Teri answered with a nod, "We really did."

"So, are you ready to get this done?"

"Ha! I was ready months ago! Let's do this thing!"

With that, the two left together to head to their graduation ceremony.

The ceremony was held in the Capital city. It wasn't that far from Hotland so it wasn't too bad of a walk. On the way, Corbel and his favorite roommate exchanged stories of their journeys as well as who they were expecting to come and what their plans were for the after party.

The conversation took them to the designated area, a sectioned off part of the city used as a park of sorts. Public announcements, speeches, addresses, and the like were given here. It was also where Corbel and Teri would part ways. With words of congratulations and a final hug, they parted to find their classes and departments.

Already, there were people lining the streets, filling in guest chairs. Corbel recognized his parents right away. And Sans, of course, sitting off near the back. The Blooks sat together as well. An empty chair between them. Was that for Undyne?

A smile crossed Corbel's face as he looked out from where the students waited to walk out. They came. His family, his friends, and his boyfriend. He was filled with an almost overwhelming sense of joy and gratitude for each and every one of them.

Not long after, he was called to his place in line. The ceremony was starting!

---

The whole thing didn't take too long. The graduating class, wasn't that big. Within every department, there were about fifty students maximum. Most only had about twenty.

There to speak words of pride and of encouragement to the graduating class, was King Asgore! He congratulated the class on their accomplishment, thanking them for all of their hard work. He gave little anecdotes about starting off on new adventures and how it can seem intimidating at first but to persevere all the same. Even if the road ahead might seem daunting or shrouded in uncertainty, even if they lose their way and stray from their paths, the important thing was to keep going. Because as long as they keep moving forward, there was always the opportunity for even more new and exciting paths to be forged.

At least that's how Corbel understood the speech.

To be honest, there were parts where Corbel kinda tuned the speech out in favor of looking around the group of his peers and spectators. The entire Royal Family was in attendance. Queen Toriel and their three children sat near the front. Then faculty, teachers, professors, deans, then the students. More familiar faces from classes and from the corridors, from the study areas, food court, the library and other hang out spots. Ha! There was Teri chatting it up with his neighbor. And there! With the Bio Engineering students! Kit was there too!? How was it that he never knew they were going to the same school!? This entire time, he could have been hanging out with her too!

Behind the students were the guests sitting, listening, waiting for their chance to cheer on their loved ones! Again, Corbel picked out the faces of those he'd invited and this time, he saw a familiar spark of red that stood out to him. He would be able to recognize that mane anywhere! Undyne finally made it!

"And now, I'd like to present to you, this year's graduating class!" Asgore announced, eliciting a round of cheers and applause from everyone.

That was their cue! The students prepared to stand with their classes and make their way to the stage up front where the lead faculty, student speakers, and Asgore stood to greet them, hand them their diplomas, and snap photos. When Corbel's class was called, a sudden wave of mixed emotions flooded him. He was excited and proud and nervous and oddly hungry and dizzy all at the same time. He adjusted the glasses on his nose. Maybe he just needed to rest his eyes for a second, recalibrate and continue.

He was near the front when he heard a little voice.

"Hi, Mr. Corbel!"

That snapped him back to reality for a moment and he turned his attention toward the voice.

"Alia!" He grinned, "Hey, there!"

He waved, spotting the little blonde girl in a white and purple dress as she sat next to Toriel. Her hair was pulled back into a single french braid and tied off with her signature red ribbon. She was beaming as she waved back to Corbel. She turned to whisper something to Prince Asriel who sat at her other side. When she finished, his eyes opened a little wider and he looked back at Corbel in astonishment. He waved as well. The third child, Corbel had only heard about them before, but never actually met them, seemed uninterested one way or the other. They looked back at Corbel as well, but just to see what the other two were talking about. They turned their attention away moments later, slumping in their chair in a visible show of boredom and frustration.

Corbel inwardly chuckled. He couldn't really blame the child. This whole thing must have been incredibly boring for them.

"Corbel Harrington Gaster!" Called the presenting faculty member.

Immediately, there was a response from the audience as a small section exploded into cheers and applause and the loud roar from Undyne could not be missed as she called, "YEAH! GO CORBEL!" from her seat. There were quite a few other cheers and more applause as well that Corbel was not expecting. He spotted Alia, Kit, and Teri applauding him, but besides them, faces he didn't recognize, people he didn't know, cheered enthusiastically for him as if they were old friends.

For a moment, it confused him, but the more he thought about it, the more he thought that maybe it had something to do with his father. The son of Dr. Gaster, creator of the CORE, Renowned Royal Scientist. And it might even have something to do with the incident as well. He had no real way of knowing, but it was definitely different than what he was expecting.

He made his way up to the stage to accept his diploma from the headmaster, who was literally a large floating wolf's head, shaking hands with the Dean of the Science Department, and meeting Asgore for a handshake and photo opp.

When he reached him, instead of the "shake and smile" approach the faculty took, the King took Corbel in a smothering hug, enveloping the young Skeleton in a cocoon of white fur. If he hadn't gasped in his surprise, Corbel might not have had enough air to make it through the embrace.

Before letting go, however, it seemed Asgore had something he needed to say to Corbel. He spoke softly in a voice meant only for him. Though with his large stature and deep resonating tone, Corbel thought it might actually be physically impossible for him to speak so softly.

"I am immensely proud of you, my boy! You've overcome so much to be here, and you've fought so hard to achieve this. I know by your sacrifice, my life, the lives of my family, and the life of a certain young girl have been forever changed for the better, and for that, I can't thank you enough. Congratulations, Corbel. It's an honor to be here to witness your accomplishment."

He released Corbel then and, while trying to catch his breath, Corbel looked up to the King with wide eyes. His mouth might have even fallen open in surprise.

"Y-your Majesty . . . ? I-I mean, M-Mr. Dreemurr . . ."

"No need to be embarrassed, Corbel!" Asgore grinned, getting into position for the picture, readjusting Corbel's glasses once again, before taking his hand to shake and resting his other on the boy's shoulder. "You've earned every moment in the spotlight."

When the photo was snapped, Asgore congratulated Corbel once again, before sending him on his way back to his seat.

When he did make it back, there was a short vibrating in his pocket and, once he was seated, Corbel pulled out his phone to read the short text.

"Congrats, Daydreamer. You deserve it."

Corbel gave his phone a soft smile.

"Thanks. I'm glad you're here. Thanks for coming."

"You think I'd miss out on the chance to watch you shine? Yeah right. I love you. There's no way I was gonna stay away."

His cheeks were starting to burn the more he read.

"I love you too." Was all he was really able to think to respond.

Sans responded a little while later with his last text of the ceremony. "Hey, remind me later that I have something for you. Something that I wanna ask you." To make sure Corbel didn't take his words the wrong way, he also included a smile emoticon.

Corbel studied this text for a long time while name after name was read off. What in the world could he possibly want to talk about? Well, at least it didn't seem to be anything bad . . . But then . . . What . . . ?

The graduation ceremony continued for almost another hour while the faculty called the name of each student and they all walked across the stage to receive their diplomas. Corbel applauded politely for each name and a little more adamantly for those he knew personally.

Soon, every student was seated once again with his or her diploma and the final item on the list was slated to be crossed off. At the instruction, the students moved the tassel from one side of their caps to the other, signifying the completion of their journeys as college students. Some, at the announcement of the graduating class, removed their hats to throw in celebration. Corbel, however, held on to his, not wanting to risk losing it.

After the ceremony concluded, it seemed as if everyone had their Corbel-seeking guidance systems activated. Within a few minutes, just about everyone on Corbel's invitation list was surrounding him in hugs and congratulatory remarks. His parents were first, his mother meeting him with tight dancing hugs and his father with a firm and solid embrace. While they were speaking, Corbel noticed a metal pin on his mother's blouse, a small bird with jeweled feathers. A hummingbird brooch.

When he asked about it, Nyala told him that his father surprised her with the handmade gift when they'd gone out for a date a couple of weeks ago. It'd been a long time since Gaster made anything for her and the gift took her straight back to their childhood when he used to make little things for her out of wire and wood. It was a wonderful reminder and made them both feel like kids again.

Corbel was so excited by the news that he crashed into his mother once again, giving her another long hug. Finally. FINALLY, his parents were trying to patch things up with each other! And it seemed as if his father was taking some of his hints and advice. The hummingbird was a brilliant first step. He hoped he kept this momentum going.

Undyne and the Blooks were next to approach, nearly tackling Corbel with a surprise come-from-behind approach as he spoke with his parents. Undyne laughed and shook Corbel in her excitement, lifting him off of his feet effortlessly and swinging him back and forth. Corbel laughed and strained to breathe through the Fish's playful bear hug. It was such a welcome breakaway from their last encounter.

Finally, last up was Sans, who, after Undyne released him, took Corbel by the hand and led him only a few steps away where he embraced him as well, whispering congratulations to him before landing a swift kiss. Corbel immediately responded to Sans with a longer, more affirming kiss, not caring about anything else or anyone else who was watching. They weren't hiding from anyone anymore. If he wanted to kiss his boyfriend, then damn it! He was going to kiss his boyfriend!

When they parted, Sans wore a furious blue blush and a nervous smile.

"W-whoah. That's not what I was expecting." Sans stammered in a near whisper.

Corbel chuckled with a smirk.

The group continued to talk about plans for later in the evening. During that time, Teri and Kit and a few others from Corbel's classes all came over to congratulate him, grab a last-minute photo, and say their farewells. Corbel congratulated them as well, reminding them to take care of themselves, or promising to keep in touch, before jumping back into the conversation with his own gathering.

His parents wanted to take him out for a celebratory dinner, but said that there was no reason it had to be that day specifically, leaving the option for his friends to celebrate with him that night. Of course, his friends jumped on that offer like Froggits on flies. Immediately, the friends made plans to steal Corbel away, saying that they were gonna take him out for drinks to celebrate. Metta made a point in making sure Sans knew he was invited too.

It took a few moments, looking between Undyne and Corbel with conflicting expressions, but in the end, Sans accepted, knowing it was what Corbel would want.

Part 3 - Afterparty

The group of them sat at their booth, laughing and telling stories, watching Corbel get more and more loose with his words and his demeanor. The suit jacket came off about half an hour ago, his tie was hanging low around his neck and his button up shirt was nearly completely unbuttoned. For the moment, he was still coherent and he wasn't quite drunk yet. But he was on a proper buzz. Undyne offered to buy his drinks this time and Sans felt obligated to warn her that Corbel could really milk that offer for all it was worth. Undyne insisted that she knew and that she was counting on it.

This became more evident when the second round of shots came through. Corbel had already ordered his favorite Long Island Iced Tea and had been nursing that between shots. His speech was beginning to become more drawn out and the tone of his voice was beginning to climb in pitch. He was really starting to feel it.

From his spot, Sans watched along with a bit of a grin. It'd been a while since he'd seen Corbel drunk and he'd forgotten how much fun it was to watch. Though, it seemed, Corbel learned a bit from last time and made an effort to take his time with the drinks. He did his best to keep his wits about him and made sure there was food at the table as well to cut the alcohol.

But as he watched, Sans knew his window was diminishing. He still had something he wanted to talk to Corbel about and the longer he waited, the smaller that window got. He needed this talk to happen while Corbel was still in his right mind.

He reached out after another moment or two of debating and took Corbel's fingers in his own.

"Excuse me, Ladies and Gentlemen." Sans interjected, coming in at the end of a good laugh about something or another, "You guys don't mind if I steal the man of the hour for a few minutes, do you? We'll be right back, I promise."

As expected, Undyne's eye immediately narrowed. Napstablook looked away toward Metta to answer for them, to which the other blook more than graciously obliged.

"Of course not, Sansy-boy!" Metta joked with a wink, "As long as you have him back at a decent hour. Though, farbeit for us to stop you from smooching right here. There's no need to drag him away for something like that."

Undyne crossed her arms, but didn't say anything to refute Metta.

"That's not why." Sans answered, actually feeling his nerves flare up a bit, "But it won't be long. You won't even have time to miss us."

"Mm? Sans?" Corbel cut in, a bit late to what was actually happening, "Where are we going?"

"Just outside for a second. Remember, there was something I wanted to ask you?"

"Oh yeaahh! Oh, shit, I forgot! Sorry, man."

Sans chuckled, standing from the booth and leading Corbel to do the same. "That's alright. C'mon, Daydreamer. The longer you take here, the longer it'll take to get back."

"You right. You right." Corbel chuckled.

The two of them walked hand-in-hand toward the exit, leaving the others to hypothesise about what what going on.

"Didn't he seem a little awkward to you?" Metta pointed out in regards to Sans' behavior. "Almost as if he's a bit nervous."

"well . . . i don't think it's so surprising." Napstablook answered, "after all, this is the first time everyone has been together like this in years. and before this, there was that thing that corbel was talking about."

"Right . . . That reminds me. Undyne-darling. How are you faring?"

"Hm?" Undyne asked as if she'd only just started paying attention, "Oh, yeah, I'm peachy."

"Is that so?" Metta pried, "Because, to me, it seems that you might be a little miffed that Sans is here as well."

"Pshh. Whatever. He's Puffball's boyfriend. He's gonna be around. That's that. Can't do much about it except deal."

"Hmm. If you say so. You'd better order another drink, dear. It'll help."

---

Outside, Corbel and Sans stood at the entrance to the bar, still grasping each others hands. It was significantly quieter outside without everyone trying to speak over each other. There were only a few small groups of friends scattered around and maybe a couple around the corner looking for some time to themselves.

A thought came to Corbel's mind and he smiled at the scene. It felt nice out here. Familiar. It reminded him of that night back in Snowdin when they stood outside of Grillby's. Sans had taken him outside then too. It'd been snowing and they shared one of his favorite kisses in that snowfall. It had been the first time he'd gotten Sans to blush.

"All that's missing is the snow . . ." He mused, only recognizing too late that he'd said it aloud.

For a moment, Sans looked a bit confused, but he caught on quickly and smiled as well.

"Yeah." He nodded, his voice quiet.

"So, you said you wanted to talk to me about somethin'?"

"Yeah." Sans repeated, drawing in and releasing a deep breath, settling himself before he continued. He turned so that he was face to face with Corbel.

Corbel blinked away the bit of delirium that was starting to settle in. He hadn't had that much to drink yet, but for some reason, it seemed to be hitting him harder this time. But Sans had something he wanted to say! He had to be alert for him! He had to focus!

"So . . . um . . ." Sans started again hesitantly, "Well, first off. Congrats again, graduate! You must be relieved that you don't have to worry about that anymore."

"Y-yeah." Corbel answered. What the heck was this about? Why was he dancing around the subject?

"And do you have plans for getting your teaching credentials already? Is that still something you wanna do?"

Corbel nodded his response and felt only a slight lag in his senses catching up to him.

"Sans, is something wrong?"

"Wha!? No! No, nothing's wrong. Nothing at all! I was just thinking . . . about what happens after today."

Okay, no turning back. Just go for it.

"School's over, so I was wondering . . . where you're gonna go now. If you're not a student, then the dorms are a no . . . Are you gonna go back with your parents for now? A-are you gonna get your- your own place? What are you gonna do now?"

Corbel froze for a moment. This was what he wanted to talk about? What he texted him about during the ceremony? What he asked him out here to-

Wait, why did he ask him out here to talk about this? Why couldn't this conversation happen inside the bar? What was the reason for bringing him outside?

Before he could register what was happening, Sans slowly dropped down to his knees, sitting back on his heels with his hands in his lap. His head was lowered before Corbel and he seemed to be having trouble keeping his breathing steady.

Corbel's eyes darted all around, looking at the others outside of the bar. Already, there were a few onlookers, and anyone could be passing by and see.

This! This looked like . . . to them, it would probably look like . . .

"S-Sans, what are you . . . ? Sans! Get up! C'mon, man! Please . . . people are gonna get the wrong idea!"

"No, they're not." Sans answered softly. "They're gonna get exactly the right idea."

Sans dug in his jacket pocket for something and when he found it, his body seemed to freeze. He looked up toward Corbel for a second before turning his eyes back toward the ground.

"Corbel . . ." He began again in that same soft voice, "I . . . wanna take this to the next step. And really, it's kinda ridiculous we haven't done this already. I mean, it only makes sense, right?"

Sans pulled the thing out of his pocket, a small and rather unassumingly plain looking rock, large enough to sit comfortably in one hand.

As Corbel stood, watching along in shock, he found it more and more difficult to breathe. He tried swallowing, to no avail. Even through the slight haze, that was quickly fading now, Corbel could tell just by looking, context aside, that the rock Sans held was no ordinary stone.

"S-Sans . . ." He stammered, "What is . . . What is that?"

"This is an option. An offer. A possible solution to the dilemma I presented."

He lifted his hands and the rock up toward Corbel. When he spoke, it seemed that he was still finding it hard to put an actual voice to his words, so it came out as more of a whisper.

"Corbel, if you want to . . . If you're ready for it. I want you to . . . I-I mean, will you . . . ? I'd like it if you . . . came to live with me."

Sans opened both halves of the ugly looking rock to reveal beautifully glittering rainbow prism crystals within. A geode with a hidden secret.

Nestled in the crystals, was a key. Almost identical to the one he gave Corbel before when he gave him open access to his studio in Hotland. But if that was the case, why would he need another key? He already had one . . . Unless . . .

"I know that it's still a bit of a leap." Sans explained when Corbel was being oddly quiet. "I get it . . . We haven't been together that long. And it is a bit sudden, but I think . . . I hope that maybe . . ."

Corbel reached out and took the stone and both of Sans' hands in his.

"You're asking me to-to live with you . . . Full time? All the time? Like at-at a place we both call home?"

Sans couldn't help the smile and the little bit of a nervous chuckle.

"Yeah . . . If you're okay with it? I've got a place lined up. So, if you want to, just say the word. It'll be our own place near the border of Hotland and Waterfall. I mean, it's a little further away from the lab . . . And the setup isn't much, but-"

Corbel silenced Sans, dropping down to his knees to close the height gap between them and leaning in to claim him with a kiss.

"Yes!" He answered firmly, "Yes, I'll move in with you!" He let out a soft chuckle, "I mean, you're right. It's a little ridiculous that we haven't done it before now. We practically live together already, right? This just makes it official."

Sans' mind was running a thousand miles a second. He hadn't thought past this point and he had no idea how to respond. Corbel said yes! He actually agreed to living together!

"Y-you haven't even seen the place yet."

"I don't care." Corbel grinned, "You'll be there! Whatever it is. Wherever that is, as long as you're there, it's where I want to be too."

Sans smiled as well as Corbel drew him into a tight embrace.

All around them were cheers and applause. Someone whistled somewhere across the road, pulling them back to reality.

They pulled away from each other and looked around. They had quite the audience. Someone was even standing at the entrance to the bar with the door open, and, at the sounds of cheers, more people came to the door to see what was going on.

"Maaaaybe we should get up . . ." Sans suggested.

"And go back inside . . . ?" Corbel continued, his face feeling extremely hot now at all of the attention.

". . . And meet back up with the others . . .?"

"Sounds good to me."

It was Corbel, the least sober of the two, who stood first to help Sans to his feet. With a few, embarrassed and apologetic waves to their spectators, they turned back to return to the bar. Of course, those who had come to the door to see what was going on cheered again as they passed, drawing even more attention from the other people inside the establishment. This sparked applause from everyone who caught the sound. Even if they didn't know what they were cheering for, or if they were too drunk to care, they applauded all the same.

The sound followed the furiously blushing couple to their seats where they returned to their original spots. Corbel raised his hands to cover his face, hiding how red it was painted.

"Okaaay. Anyone care to explain what in the world is going on?" Metta pushed, "What have you done to cause such an uproar?"

Both Sans and Corbel were speechless from shock and embarrassment. Corbel, however was able to take the rock and place it on the table between them.

The other three friends studied the thing.

"It's a rock." Undyne muttered.

"there's a break in it, though." Napstablook hummed, tilting their head to see, "this rock is different."

For a moment, Undyne and the Blooks looked up from the rock to Corbel's brightly colored face and toward each other. That, plus the cheers and applause from the other bar goers could only mean one thing.

Metta's eyes widened when he realized what that was. A wide grin spread across his spectral features.

"Sansy-boy!" He gasped in astonishment, "You didn't!"

"Didn't what?" Both Undyne and Napstablook questioned.

"He proposed!"

"He did what?" Undyne nearly growled.

"It wasn't a proposal . . ." Sans immediately jumped to the defensive, "Not really. I mean . . . I guess it was, but not marriage. We're not getting married! Just . . . Here. Look."

Sans reached out for the rock and opened it to show the others the geode and the key inside.

"Quite an elaborate setup if you ask me." Undyne muttered, "Corbel's always liked finding geodes. To use one now, on a day like today, after a few drinks."

"It's not like I planned all of this." Sans shrugged, "After all, it was your suggestion to come here. I just brought the rock."

"This calls for another round!" Metta exclaimed, already beginning to float up and over the table. Anything to cut the growing tension a bit. It seemed as if poor Corbel was still too shocked to do much of anything and he already knew his dear cousin would not do much to quell the nerves, so the responsibility of ordering the next round of silly juice fell to him.

---

The evening continued.

When Corbel was able to, he retold the story of what happened outside and just how Sans presented him with the key. It really did look and sound like a marriage proposal . . . And Sans even said that those looking along would get the right idea . . . which Corbel supposed wasn't entirely false. They would be living together from now on, joining their lives together. It would just happen without the big to-do of a ceremony and vows and all that. They didn't have to deal with the pressure of being labeled as a married couple. And if they decided to later on, the option was still available. Overall, it was a pretty decent deal.

These thoughts only occured to Corbel for a few fleeting moments before realizing he was probably reading way WAY too much into it.

He was thinking too much.

From his side in the booth under the table, there was a light brush of fingers. A tiny gesture. Discrete. Corbel smiled taking Sans' fingers hostage in his own.

Throughout the evening, the others made sure Corbel was having a good time. He laughed a lot and relaxed with his friends in a way he hadn't in a very long time. And though he was careful and more aware of his actions, with the help of his friends, he'd still managed to get pretty drunk. The others seemed to really enjoy the more carefree side of their inebriated friend. He was a lot more vocal with his opinions, if a tad bit louder than usual. He was in constant smiles and giggles as he spoke with his friends and as Sans sprinkled in a few jokes and puns.

As the evening wore on, it seemed Corbel had forgotten about being bashful when it came to his proximity to his boyfriend. The embarrassment from earlier faded completely and Corbel scooted to sit very close to Sans, nearly leaning on top of him. He'd even taken to muttering almost sickeningly sweet things to him in low tones. In response, Sans, who had also had quite a bit to drink himself, welcomed the closeness, but reminded Corbel that his friends were there too and to make sure he didn't forget about them.

Metta watched the two with stars in his eyes. After so long, his friend was finally happy. He was on a path in life he wanted to be on. He'd finished his college education for the moment and he was happily in love, ready to start a new chapter with his chosen one. And not just with anyone, with the one he'd been pining over since high school. It was a long time coming and so many obstacles had gotten in his way, but he pushed through each and every one of them to make it where he was. Metta could honestly say that he was so immensely proud and happy for his dear friend and he couldn't wait to see what the future had in store for him and his love.

---

When Corbel began to get drowsy, they decided to call it a night, splitting the tab according to their arrangements, and stepping outside once again. Undyne took it upon herself to assist Corbel along and even though the Skeleton protested and insisted he could walk on his own, his swaying steps said otherwise. In the end, he conceded and let Undyne lead the way, while all the while, he leaned on her and used her solid frame to guide him.

On his other side was Sans, poking fun at Corbel for how much he was relying on Undyne's help even though he said he'd have things under better control this time. Corbel insisted that he did have it under control and if he wanted proof, to just wait until they made it home and he'd show him just how in control he was.

Sans laughed, though he wasn't quite sure what he was supposed to take away from that. Was it a threat or a flirt?

"Don't make promises you can't keep." Was his response.

Undyne rolled her eye at the two of them, muttering "gross" under her breath.

The Blooks took their leave not long after that, saying that it was about time to head home and they would have a busy day tomorrow. They congratulated Corbel once again, not only on his graduation now, but for the beginning of a new chapter of his life.

Sans considered doing the same, head home for the night and let Undyne take Corbel to the dorms. But when he said this out loud, Corbel protested adamantly. He held out his hand for Sans as he was preparing to leave, and waved him back over. He told Sans that he was not allowed to go home until he said so. That he was Corbel's prisoner.

Again, Sans laughed, following alongside with a bow and an, "As you wish."

The rest of the walk didn't take long. Mainly because Undyne thought it would be faster if she just carried Corbel home on her back instead of having him stumble around. As usual, Corbel protested, but Undyne did it anyway and once they were on their way once again, Corbel caved, pouting a little at having to admit that it was, indeed, faster. Sans patted his back, telling him that it was okay and that there was nothing to be ashamed of.

When they made it home and Undyne set Corbel down once again at the door, it was a little awkward for a few moments while they decided how to end the night. It was implied that Sans would be staying the night and Undyne was visibly perturbed by the thought.

With a bit of a huff and a plastered fabricated smile, Undyne waved to Corbel, congratulating him once again and instructing him to get some actual rest. She said that she didn't care what they did once they were inside as long as Corbel didn't overdo it.

Before she left, she briefly turned her attention to the other "Skeleton".

"Make sure you take care of him, punk. You should be able to handle it this time, right?"

"Yeah." Sans answered, gritting his response at the obvious jab.

"I already did the hard part and brought him home." She continued, "Make sure he drinks water and he actually sleeps."

"Got it . . . I got it."

"I sure hope so."

"Weee'll be fffine, Red." Corbel scoffed, stepping in to lean over Sans' shoulders and hold him from behind, "Donn't worry sumuch."

"Sure." Undyne finally groaned, stepping away, "Well, see ya."

Corbel waved from around Sans, seeing Undyne off with a bit of a smirk. As soon as she was gone, his composure slackened and his smile somewhat faded.

"Geeeezzz. I wish you guys got along better." He moaned, "She juss won't let you off the hook, huh?"

"Yeah." Sans agreed, "An I don think she was too happy about us movin in together."

"Well, thass her problem. Not ours." Corbel turned his face, kissing Sans' cheek with a new smirk in place, "C'mon, Stargazer." He whispered through a soft hum, "It's late, and I'm sleepy. I wanna listen to that heartbeat of yours."

A tiny part of Sans stiffened as he listened before falling into Corbel's trap. "Alright then." He smiled back, "Inside with you."

They spent the night in each other's arms, sleeping soundly until morning.

Part 4 - Homecoming

Over the next week, Corbel and Sans took the first steps to move in together. Highest on the priority list was Corbel. It was essential that he get his things out of his dorm in time for the next semester to start and the next tenant to move in. There was less of a rush for Sans to get his things in, though he still needed to be moved out of his studio by the end of the month. So, while Sans was at work, Corbel moved what he could on his own, relying mostly on magic to do the heavy lifting for him.

The thing he had been looking forward to the most was that first night the two of them shared in their own place. In their own room. In their own bed. True, they'd spent several nights together before that night, but something about that particular night was special. It was a feeling of joy and of freedom and of accomplishment. They were finally completely on their own. They were established.

Sans was exhausted, but Corbel made dinner for the two of them, another recipe from his mother that she called "dirty rice." It was a simple meal with few inexpensive ingredients. Upon coming home, their shared home, Sans sighed in relief and sat down on the couch brought over from his studio. He leaned his head back and nearly fell asleep right then.

With a bit of a sigh of his own, Corbel brought over two bowls of the dirty rice and sat next to his sleepy scientist.

"Welcome home." He greeted softly, placing a gentle kiss on his cheek.

Though he kept his eyes closed, the smile he wore was unmistakable. He hummed his response.

"Are you even hungry right now? You look more exhausted than anything."

Sans hummed again with a slight nod.

"Is that yes, you're exhausted or yes you're hungry."

Another nod.

"Fine. You rest for a bit, then. Dinner later. Dirty rice reheats well."

Another hum. Sans cracked an eye to look over toward Corbel, "I love you so much. You really are incredible, you know that?"

"Why? Because I know what you're saying even when you suck at communicating?"

"Exactly. That's quite a feat."

"That commute knocked you flat today, huh?"

Sans shrugged. "Maybe a little. It's a bit longer than I'm used to, but I'll acclimate."

"Well, Sleepy Bone Jones, I'm glad you're here all the same. Do you happen to know what today is?"

Sans opened both eyes into delirious slits. "Hm? What'd I forget?"

"You didn't forget anything." Corbel smiled sympathetically, "It's just that today is Day 1. The start of this official togetherness thing. This is the first night we'll both be here at the same time!"

"It's that so?" Sans smirked, "I guess it is. And I guess you wanted to make it special, huh?"

Corbel shrugged, "It's not a necessity, really. I just thought it was pretty cool."

"And so it is. Hmm. In that case, how about we . . ."

"How about you get some rest. Dinner's not going anywhere. I'm not going anywhere. You, on the other hand, look like you're about ready to drop."

"Well, it looks like I can't really argue. Fine. Rest first."

Corbel reached a hand over the back of the couch and draped it around Sans' shoulders. He led Sans down to lie in his lap for a moment.

He was asleep within five minutes. His breath was calm and deep as he relaxed.

True to his nickname, Corbel spent the recently acquired free time sitting with his sleepy scientist boyfriend, stroking his skull, enjoying his company, and daydreaming about tomorrow.

---

Another month or so passed and the two settled in to life together rather nicely. They already had a rhythm and an understanding and they adjusted well to each other. Corbel was definitely more deft in the kitchen and to make up for it, Sans kept the kitchen clean for him. Every once in a while, however, Sans would surprise Corbel with one of his favorite meals.

One week, Sans made homemade burgers with cheese, bacon and mushrooms stuffed into the patty. He found the look on Corbel's face absolutely priceless when he realized what made these burgers different.

Another week, they had a taco night. It was brought to Sans' attention that Corbel had no idea what a taco was and that was absolutely unacceptable! So Sans made an entire display of it, setting up an assembly station so he could teach Corbel how to assemble the perfect taco as well as the difficulty of the hard shell vs soft shell dilemma. And just how many forms tacos could take. He branched into nachos and burritos as well.

Corbel seemed to enjoy the convenience and portability of the burrito, and the freedom of the taco salad. He topped just about everything with sour cream and salsa and Sans nearly had to wipe a tear of pride away.

They would have to make tacos more often.

As the next month rolled around, it was a Corbel's turn to set up a surprise. It was the beginning of February. He'd been preparing for this ever since he found out and it was finally time to set his plans in motion.

Sans' birthday!

He'd spent the entire day setting up while Sans was at work, he'd studied the stuffed burgers and recreated them. He was ready to make mixed drinks for them. And the apple spice birthday cake was just about finished. He just needed to ice it.

When Sans made it home that evening, he already knew there was something up before he opened the door, as if he could sense the energy from the other side.

He opened the door slowly and immediately was hit in the face with pleasant scents and bright colors.

Corbel rigged the door with a classic bucket prank, so that when Sans opened it, it would dump a bucket of balloons, glitter, and confetti on him.

"Wha . . . What the!?"

"Happy Birthday, Babe!" Corbel cheered, stepping out of the kitchen area with a paper hat in his hand.

For a second, Sans seemed dumbfounded, looking around and trying to make sense of the onslaught of information. After that second, he blinked back to reality.

"Wait . . . I'M 'Babe'!?"

Corbel laughed out loud at that. "Yup! And there's nothing you can do about it!"

Corbel slipped the pointed paper hat on Sans' head, securing it under his chin with the elastic strap. Corbel was already wearing a matching hat and a bright smile as he chuckled to himself. Sans was completely covered in confetti and glitter and the balloons littered the floor around them. Stage 1 was a complete success!

Sans took another look around, really taking everything in. Corbel put in so much effort to bring this all together. How much work had he put himself through for this?

"Why . . . ?" Was the first thing to escape Sans' mouth. He couldn't seem to comprehend just what was happening.

Corbel tilted his head in question, studying Sans' bewildered expression. "Why?"

"Why would you do all of this for me?"

"You have to ask? Because I love you! Because I want to make your birthday special. Because until recently, I didn't even know when your birthday was and I wasn't about to miss another one! Because, for once, I want to spoil you. I want you to know how special you are to me. Because you deserve it!"

Eventually, the thought seemed to sink in. A tiny smile crept across Sans' face and there was a bit of a sting in his nose and eyes.

"You didn't have to do this . . ."

"No, I didn't." Corbel shrugged, taking both of Sans' hands and stepping close, "But that doesn't mean I didn't want to. I'm sure we've said this a thousand times to each other already, but that doesn't make it any less true. Besides, we've never celebrated your birthday in all the time we've known each other. So . . ."

The smile spread and Sans had to close his eyes and draw in a long breath.

"Thank you, Corbel."

"Aw, no nickname?"

"Alright." Sans chuckled, still a little water in his voice, "Thank you . . . My love."

Corbel choked, completely surprised at the unexpected term. There was something about it that was just so . . . candid and raw. He heard the level of conviction in Sans' voice and knew that it wasn't an exaggeration. That's what he really thought . . . Corbel's eyes widened and his breath caught as he was struck completely immobile.

Sans caught Corbel in a hug then and the two stayed that way for a while just drinking in the other's company.

---

That night, after dinner, after Corbel sang happy birthday to Sans, and after the birthday cake dessert, Sans insisted that he get started on the dishes, Corbel had done so much for him already that he shouldn't have to worry about something like that. In response, Corbel grabbed the hem of Sans' shirt, as he was getting ready to stand, and pulled him back down to the couch.

"Hm?" Sans questioned, "What's up?"

"N-Nothing, just . . . That can wait, can't it? You're not gonna do dishes on your birthday."

Sans' eyes narrowed as he looked back to Corbel. That stammer in his speech sparked the slightest suspicion.

"I'm not gonna let you cook and clean too. You did one, so I do the other. That's how it works."

"Yeah, but . . . Right now?"

"Why not now?"

"Because . . ."

"Because . . . ?"

"Fuck, Sans. Do I need a reason?"

Sans gave Corbel an impish smirk. The absolutely perfect opportunity to completely mess with him arose.

"If you want to keep me here, you have to have a good excuse. I won't accept anything less."

Corbel groaned in thought and pouted before letting Sans' hem go with a sigh. He lowered his head.

"W-well . . . I was hoping . . . to give you your present now." He answered, muttering his explanation in a low voice, "But if you insist on missing out so you can clean some dishes, then, go ahead . . . but-but this is a limited time offer and it will expire once you leave."

The smirk never faltered. Sans watched Corbel build up his excuse from nothing and had to admit that it was a pretty good excuse.

"Fine. You win." He responded, shifting to sit even closer to Corbel. He lifted his hand to brush Corbel's cheek with his thumb. "I'll stay if your present has an expiration. What did you have in mind?"

Sans watched as Corbel's face went red, almost completely skipping over the orange colors of his fainter blushes. When he spoke again, the low mutter had become a whisper as he leaned in.

"Well . . . considering . . . well, everything, I-I wanted to get you something really special . . . But I c-couldn't think of anything perfect enough to-to give you. S-so . . . you're going to have to settle for . . . j-just-just me."

Sans' brow raised in question, "Just you? Wha'd'ya mean?"

Corbel's previously coy demeanor shifted and became sheepish, "Sorry, I couldn't get you anything better."

"No, I mean what do you mean, 'Just you'?" Sans explained, "There's nothing 'just' about you. And spending time with you really is the best birthday present I could ask for."

"No . . . Sans. You don't get it."

Corbel shifted once again with a shallow breath, and reached across to slip a hand over Sans' hip to grab at the fabric of his jeans. He used that grip and the frame of the couch beneath him in order to change positions, lifting himself up to straddle Sans hips and sit in his lap.

Sans' eyes went wider and he seemed to be having trouble breathing now as he felt Corbel adjust himself over him. This was . . . definitely different than what he thought Corbel meant.

"O-oh . . . 'Just you'."

"I-I hope that's okay." Corbel stammered, his face beet red now. But even through his nervousness, he was set in his resolve. He kept his voice low so the only way Sans would be able to hear him was if he gave him his undivided attention. "You see, I wanted to give you something special- something only I could give you and . . . well . . ."

With a fleeting brush of his fingers, Corbel gently caressed Sans' chest under his shirt, gaining a shuddering breath from him.

"And it's okay if you don't want me to see." Corbel continued, his speech finding a bit more conviction, "I don't have to see. I just . . . I want to take care of you. I want you to have a really, really good time."

Before the young Skeleton could go too far, Sans' hands found Corbel's wrists and slowly, reluctantly, pushed them away and from under his shirt.

"Nngh, Corbel . . ." He began in a soft apologetic voice.

Corbel's eyes widened now, sobering immediately as he realized his mistake. "Oh! Of course . . . I-I never asked you . . . If-if y-you don't . . . If you don't want to, then I . . . I'm so sorry! I-I just . . . I'll just . . ." He made to pull away in order to grab the dishes.

"No!" Sans protested, holding the younger Skeleton's wrists tightly to prevent him from leaving, "I never said I didn't want to . . . Just . . . are you sure? This is kind of a big deal. Don't do it just because of what day it is."

The two locked eyes, each studying the other, searching for conviction and resolve.

"I'm absolutely positive." Corbel answered, "I know I've wanted it for a long time. I just . . . never knew how to ask you . . . and now, it's even more confusing . . . I have absolutely no idea how this kind of thing works for humans . . . Or, if the human way will even work for you considering your situation and all . . ."

Sans actually released a puff of laughter. "In that case, we're the same. Because I really don't know how it works for Skeletons either . . . So, I guess we'll just have to figure it out together, yeah?"

Corbel visibly relaxed, "Well then, let me at least show you the Skeleton way. But . . . You'll have to be patient with me while I figure this out. This is my first . . . well, you're my . . ."

Sans tilted slightly upward and cut Corbel off with a soft, slow kiss. "It's okay. I'm new to this too."

They kissed again, Sans finally releasing Corbel's wrists to grab the end of his own shirt now.

"I-I think it's about time I showed you . . ." Sans hummed, "Are you ready?"

Corbel swallowed, biting back his excitement and nerves. He nodded.

Sans pulled the fabric up, slowly. Slowly. Over his lower ribs and up toward where there was a soft deep blue pulsing of light.

Corbel was immediately entranced by it. In actuality, it wasn't all that different from a Monster's Soul. But, at the same time, it was absolutely and completely different. Shining pulsing color, full of life and vitality and strength and . . . completely upside down . . . So, it wasn't just Sans' magic that was blue . . . it was him. He was blue, down to his Soul.

If Corbel ever needed definitive proof of Sans' claim to be human, this definitely would have been it. No wonder he was so protective of it . . .

Well, it wasn't like Monsters went around brandishing their Souls to one another either . . . That would be inappropriately lewd. It was the ultimate exposure and something to be held private, revealed only to those you trusted completely.

And here Sans was, for the first time, revealing what his Soul really looked like, his shirt completely removed now. He was blushing now too . . . blushing red. This wasn't an extension or a flare up of magic. This was something completely different.

"Well, w-wha'd'ya think?" He asked nervously. "I'm kinda . . . barin' it all for you."

Corbel had to rip his eyes away for a moment to refocus. "I think . . . It's . . . Your Soul is . . . absolutely beautiful."

The blush spread, his eyes widened once again. He didn't know how to respond.

"Now, then. Let me even the playing field a little." Corbel hummed, leaning back slightly and gripping at his own shirt.

Sans kept his hands over Corbel's hips as he watched, remembering a time, not too long ago, when Corbel was so self conscious over showing anyone anything. He would go to extremes to make sure that no one was able to see his cracked and porous bones. Now, since the incident, he was significantly more confident in the way he looked. Sans could still see some of the areas where his ribs had eroded or points where he had to be broken in order to work in the new grafts, but it was difficult. He could only tell because he knew what to look for.

Even so, Corbel kept himself curled up, his arms wrapped around himself, shy to show himself.

Sans put on a smile for him as he reached upward to lower Corbel's arms.

"Hey." He said softly, "It's only me. And I happen to think you look great."

Slowly, Corbel let Sans lower his arms and once he did, Sans could see the white monster Soul floating just within the repaired ribs. There was a subtle glow to it, not as bright as his own, but iridescent all the same. And upside down . . . Huh . . . That was definitely different.

"You're sweet for saying that. And generous." Corbel sighed in response to Sans' comment. He smiled, still avoiding direct eye contact as he held a hand forward, focusing his energy and calling forth on his magic. He manifested his Soul in his hand so it floated a few centimeters above his palm. He made himself completely vulnerable.

"But, you see, my Soul is . . . Atypical. It's . . . Well, it was falling apart. It kept fracturing and flaking so I could use it to keep from turning to dust when I was a kid. Then, after the incident, it was Dad who kept me together. But you can still see the splits and fractures a little. But the strangest thing about my Soul is that it's off-color. I . . . Have you to thank for that, actually. When you gave me your HP. You were giving me part of your own Soul. I . . . Absorbed your Soul and it gave me more strength. I stopped crumbling, I stopped coughing up dust. I stopped falling apart. You didn't just save me from the incident. You saved me from my own disease. The cure my dad was looking for . . . The missing piece to his master's research . . . It was you. The pure essence of a human soul. Just a sample. Enough to stop the spread, but not enough to transform me completely . . . And you just . . . Gave it to me."

Sans watched along as Corbel explained. He had no idea how it even happened and he didn't even know he was doing it until it was already done, but now that he looked at Corbel's soul, he could see that he was right. It was very faint, almost undetectable, but again, because he knew what he was looking for, he could see the very slight blueish tint to the Soul, pulsing in time with Corbel's light.

"The thing about this . . . The thing that makes this even more taboo than it would normally be . . . Is that . . . Now, don't freak out . . . But this . . . Is sorta how baby monsters are made."

Despite himself, Sans stilled, going completely stiff.

"Hey, I said don't freak out!"

"Yeah . . . You expect me to be calm after dropping a bombshell like that!? To recap, you just told me that because of what I did, I could've . . ."

"No, you couldn't have." Corbel reassured, "I said it was similar, but the actual process is . . . A bit different. You see, when two monsters love each other very much-"

"Oh God, this sounds familiar."

"You were curious. And I don't want there to be any sudden surprises when we . . . Anyway, when two monsters decide they want to create a new life, they first agree that it's indeed what they want. It's a conscious agreement and once both parties are willing, each Soul becomes open to being a carrier.

"When we . . . 'engage' . . . at that point, our magic flares and our Souls meld. At the . . . the moment of climax, there's a spark- a flash of light . . . Which happens whether there's a baby or not. It's how our bodies release the tension . . . when it's properly released anyway. In a couple, that spark is then contained within the most receptive Soul and that monster carries the new Soul until it's strong enough to take its own form. Their magic manifests in the carrier Soul and flares sometimes, which makes for some awkward and colorful hot flashes within the parent. And when looking at the carrier Soul, you can begin to see the color of the child's magic as they become stronger. It's . . . actually pretty beautiful to witness. Or, I imagine it would be.

"When the carrier Soul shines completely in the color of their child's magic, they separate their Soul, expelling that magic, and manifest it outside of their body, like I'm doing now. At this point, the new Soul will form and the magic should take shape. The baby monster."

Sans listened quietly to every word, picturing it in his mind.

"Man, seems a lot less complicated and messy than humans. Everything happens on the inside and when we . . . when we 'engage' . . . conception is almost completely random whether you want a child or not. And there's a lot of fluids involved and it's always the female who carries the baby and it's a really painful process to give birth. It's bloody and messy. I think I prefer the monster way."

Corbel recalled his Soul and it floated once again within his rib cage as he watched Sans for a moment. "That sounds terrible. Why do humans decide to do that, if it's so painful? And it's random whether they make a baby or not . . . ?"

"Without proper countermeasures." Sans shrugged. To him, it was the most natural thing in the world after all.

"And you said it all happens on the inside . . . ? I mean . . . I've seen some pictures before about the way humans mate . . . Photos and magazines. Things that they threw away, but it never made any sense to me. Maybe . . . There's a way that you could . . . Enlighten me . . . ?"

At the mention, Sans drew in a breath, beginning to feel a tight hold in his chest and a bit of an anxious anticipation, an uncomfortable tension building up. And now that he knew about the connection between his Soul and Corbel's, he wondered just to whom this feeling belonged.

He decided to roll with it.

"You know, Daydreamer." He chided, his voice low and his devilish smirk back in place, "If you wanted me to show you, all you had to do was ask. I happen to have everything we need for a full lesson right here."

For a moment, Corbel's face fell into a confused frown, until a certain jump in his chest took hold. Something within Sans was beginning to change and it was beginning to affect him as well.

Sans' eyes lowered for a moment to where Corbel still sat in his lap with a leg to either side of his hips. Yeah, he was going to have to do something about that soon.

But first . . .

"I'll show you exactly how it works with humans. Or, at least, this human. By the time I'm done, it'll all make perfect sense why we do it. But first, you need to show me how it works with Skeletons. Show me how you like it."

Corbel hesitated again as he listened to the darkened tone Sans' voice had taken and finding it hard to keep his constitution about him. It was contagious, but it was a fever he'd been desiring for quite a while now. And now that the rules had been explained, it was time to get this game started.

He'd dreamed and fantasized about what this moment would be like and now he and Sans were both finally at a point where they were willing to try.

It was a literal dream come true.

His own smirk forming as he leaned in over Sans once again, Corbel nodded.

"Alright then. Let's begin with lesson one."

With a tight swallow and his breaths becoming more shallow with the promise of an unforgettable evening, Corbel shifted again in Sans' lap, preparing himself for what he'd been hoping to do for years.

Part 5 - Mr. Corbel

Over the next year and a half, everything seemed to go pretty well for Corbel and those around him. In accordance to his plans, he studied to obtain his teaching credentials so he could begin as a Science teacher. At first, he started out as a teacher's assistant at a local elementary school to get a handle of things and he was quickly able to become a substitute teacher. Really, it was just a filler position until the full-time opportunity hit.

In the meantime, he used his free time to meet up with his mother to compare teaching strategies on top of just the general catching up. Since he and Sans lived closer to home than they did before, it wasn't much hassle for her to stop by every once in a while or for Corbel to visit his parents.

It sounded as if things were going pretty well at home too. His father was making an effort to mend things between him and his family. They were making more plans to go out or stay in together and enjoy each others company. Not only was he making the plans, but he was actually sticking to them. It was such an improvement.

Once Gaster was able to hire on his newest intern, a young Reptilian engineer by the name of Alphys, he was able to relax a bit more and delegate the workload so that it gave him more free time to spend.

The whole thing really was turning around for them and that news made Corbel feel more at ease as well.

As a bit of an insider resource, Sans was able to vouch for Alphys as well. He told Corbel about her from a work perspective. Diligent, creative, intuitive, resourceful. As a person, she was a little awkward and didn't have much in the way of social skills, but she was always good for a second opinion and an out-of-the-box perspective. She had already helped out with some of her more unique takes on her assignments. She'd even come up with some design elements for one of the assignments he and Gaine had been working on. If they're lucky, it might lead to the solution they were looking for.

She really seemed promising. Corbel was glad that someone so competent was helping around the lab now. It actually made him feel a little better about leaving. It gave her the opportunity she deserved and the lab the push they needed.

Eventually, Corbel got his lucky break: a full-time faculty position as a Science teacher for elementary age children! It was the perfect blend of what he'd studied and what he wanted to do. He could use all of his skills to the fullest!

He took every opportunity to teach the children all of the basics. The Scientific Method and how to conduct basic experiments, how to apply those skills to other aspects of their lives. He helped them discover how science can be found and used all around them. He was so proud to see his students understand and use what he taught them. They were so smart!

He taught his kids little tricks to help them study. He wrote little ditties and songs to help solidify the lessons and help commit them to memory. His chest tightened with pride when he heard them singing the songs back. It nearly made him cry the first time he heard those little voices singing back to help them through their worksheets.

At home, Sans noticed a change in Corbel as well. He was actually genuinely enjoying his work in a way he'd never seen at the lab. When he came home from work, he was all smiles and songs and it made Sans smile as well. As proud of Corbel was of his students, Sans was even more proud of Corbel. He loved seeing him so content. He always had a story to tell about his students and it showed just how much they meant to him. The only real stress he had was if there was a kid who was acting up or he had to grade piles of tests or assignments that would sometimes take him into the early hours of the morning. But those were minor things.

There wasn't even any stress with his new coworkers. So far, they'd all been supportive and encouraging. They might have seen him as a bit young, but that just made it all that easier to connect with the students. Already, he had a rapport with them and they were warming up to him more and more by the day. After taking over for a retired teacher who'd been there for so long, the other faculty thought it might be difficult to fill those shoes, but it seemed as if Corbel was doing it fabulously in his own way. He was the only teacher who the students called by his first name, addressing him as 'Mr. Corbel' instead of 'Mr. Gaster,' which, the other teachers supposed, made sense so they didn't get him confused with his father.

Finally, as a fully fledged member of the faculty, Corbel was able to do exactly what he'd always wanted. He was able to set up and get approval for exploratory field trips! One Friday of every month, he set a destination and constructed an activity or an experiment for the kids to do when they got there. They would take their observations or the results of their experiments home and write reflections on them over the weekend. He would ask them to answer questions like: Where did they go? What did they like about the location? What examples of (whatever it was they happened to be studying) did they find at that place? If it was an experiment: Why did they think they got the results they did? What were they hoping to find? What they would do differently if they tried the experiment again? How did they think those changes would affect the result?

The field trips were a hit! The kids loved being able to get out of the classroom every once in a while and do activities outside. They enjoyed the observations and experiments and getting more hands-on with the things they were were learning to have a deeper understanding of their home and how everything connected together. And, of course, they loved the fact that they had Free Time at the end of every trip where they could have fun at their destination, like an extended recess. The field trips were so much of a success, in fact, that even the King and Queen's children began to frequent the outings, accompanied by Queen Toriel as an extra chaperone!

Corbel's personal favorites were the trips to the Wishing Room where the kids made wishes on the glowing stones. They studied why some of the stones glowed while others didn't. They even tried to find patterns in the rock formations above and drew them out.

His other favorite was the Echo Flower room where he set up a scavenger hunt using the flowers to give out instructions to the kids. Of course, going in, he had to make sure the kids didn't speak over the flowers and erase the instructions, so he set an extra prize for the group who could get through the hunt the quietest. He was also prepared with a system to keep this in check. He prepared a map with which flowers had which clues. If a student spoke and overwrote the flower, he would go and reset it, being sure to mark a point against which ever group did the overwriting.

There was one group who had to be completely disqualified for making inappropriate comments to the flowers that were then repeated several times throughout the room.

Much to Alia's and Prince Asriel's dismay, as well as Toriel's disappointment, the second human child, Corbel believed their name was Chara, seemed so disinterested in the activity that they prefered to make it into a mean joke. Their group was disqualified and asked to sit out the rest of the hunt. Toriel apologized for her human child and assured that she would handle the situation more thoroughly once they made it back to New Home. They left that outing early.

The strangest things came after that, though. A request and an attempt to make amends, both coming from the Capital.

There had been talk of having Mr. Corbel host a tour at a predetermined location. More specifically, his father's lab! It was already in the works when Corbel got the request. It was agreed that Corbel's prior experience in the facility made him the best candidate to lead the tour. The students would take a tour of the upper two levels of the lab and the workers would take a moment to explain their individual roles at the lab as well as what inspired them to become scientists. Dr. Gaster included!

Corbel thought of it as sort of a reverse Career Day. The students could see the kinds of things they could do with the science they've been learning and explore what they wanted to do in the future. It was a good opportunity for them.

If they stayed to the first two levels of the lab and had him, plus the eyes of all of the assistants, and the chaperones on them, Corbel supposed it would be okay.

When the time came for the field trip, Corbel found that he was both excited and nervous about going back to the lab. He missed going and he missed seeing all of his coworkers, plus, he had an actual excuse to bother Sans at work, which would prove to be a fun use of his time. But at the same time, the anticipation and anxiety that came with going back to the lab ate away at him a little. Like going home and showing his parents a report card and awaiting their judgement. Of course his father knew he was a teacher now, but he'd never seen him on the job, he'd never met his class. Corbel felt like it was an evaluation on him, a living report he needed to submit.

Along on the trip, were Alia, Chara, and Asriel, but there was no sign of Toriel. Apparently some urgent business had come up and, she needed to see to it with her husband. The children should have fun on the field trip and she knows that with so many trusted adults around, they'll also be in good hands.

They were greeted at the door by a small monster with a bright friendly smile. Upon seeing them, she waved.

"Corbel! It's so good to see you again!" She cheered, "It's been forever!"

"Hi again, Baelin! Class, this is Ms. Marielle Baelin and she was one of my colleagues when I used to work here in the lab!"

A chorus of children answered back, waving and saying hello.

"Alright, kids!" She announced, "You're in for a really fun day today! You get a tour that no one else has ever had before! You're gonna be the very first people to see what we do here at the lab! Not only that, but you all get to be honorary assistants for the day!"

There were quite a few cheers from the kids. Many were excited at the mention that they were the first.

It went mostly unnoticed, but near the back of the group, a certain young human stood with their arms crossed and a smug expression on their face. It'd been their idea to suggest this field trip to begin with and their suggestion to the King and Queen that got this whole thing going. Now, finally, after an eternity of waiting, they were FINALLY gonna get that tour they wanted.

Baelin led the way, showing the students in through the front door. Corbel stayed in the back, making sure none of the kids wandered off.

Inside were the rest of the assistants waiting for the group. Maltez smiled and waved, but mostly at Baelin.

Ruddard nodded, welcoming the children and acknowledging Corbel when he saw him. Corbel nodded back.

Further back was Gaine, who made little motion but did make eye contact with Corbel. Corbel nodded to him as well.

To his side was his father, wearing a courteous and welcoming smile for the class, though, Corbel could tell that it was a bit forced. It'd been forever since he's had to deal with kids. Corbel had to chuckle a bit at that.

Next was the new intern, a short-ish yellow Reptilian with glasses and a hunched posture. She looked completely anxious. Maybe it was the crowd. Maybe it was because of all the kids. Corbel had no idea.

And finally, off to the right, closest to the wall was Sans with his hands in his pockets. He kept his eyes locked on Corbel with a grin.

Corbel smiled back, but he couldn't keep the eye contact Sans could. He turned his face away, fighting off what would surely be an incriminating blush. He still couldn't quite shake the tightening in his chest whenever Sans smiled at him like that.

But they were on the job! They both were! Flirting would have to come later!

But that didn't seem to matter to Sans. As soon as everyone was introduced and the students received their own name tags and clipboards, Sans separated from the others and joined Corbel in the back of the group, standing recklessly close and "accidently" brushing up against him.

While they stood in the back of the room during Maltez's magnesium demonstration, Sans leaned against the wall and held Corbel's hand. Then, throughout the day, they kept shooting quick glances at each other and teasing each other, all the while trying to make sure the others didn't notice.

For the most part, they were successful, but there were a few people who caught bits and pieces of their exchanges.

The Dreemurr trio were among those who noticed. Asriel understood what was going on right away. After all, his Mom and Dad were always playing around like that. They even had a trophy for nose nuzzling off all things! He could see the flirtatious aura the two were giving off from a mile away.

Alia was glad for them. It was nice to see both of them so happy. She remembered when Sans was so anxious and afraid that Corbel was going to die, that he couldn't sit still. He was pacing the floor on his injured leg and stressed out when there was no update on Corbel's condition. To think that these were those same monsters from that time, laughing, prodding each other, whispering to each other. It warmed her heart to see.

Chara studied them as well. Not only them, but the reactions to them. Chara recognized the teacher's boyfriend from the last time they snuck into the lab and they already didn't like him much. There was something about him that was just plain weird, and though they couldn't put their finger on it, it rubbed them the wrong way.

Still, they kept an eye on him as he stood suspiciously close to the teacher. The two of them thought they were being subtle with their flirting, but there were a few others who caught on. And some of them didn't seem to be particularly happy with what they saw. The main doctor, Corbel's dad, Dr. Gaster, seemed annoyed at most. He kept his distance and his gaze averted. The other was another one of the doctor's assistants. A big Cat guy who obviously wasn't very happy. He kept glaring at the two and rolling his eyes. This sparked Chara's curiosity. They wanted to know more about him.

And as luck would have it, that assistant's turn with the class came up right after lunch. He, the doctor and the short Skeleton were all talking to them about the energy source that powered the Underground. The CORE.

At first, their teacher seemed taken aback when he learned they'd be taking a class full of children 10 and younger to a place that was so . . . not kid friendly. But his boyfriend assured them that they would just be sticking to the outside of the CORE and talking about its functions. They wouldn't even be stepping foot inside. At that information, Mr. Corbel was more willing to venture forward.

While at the CORE, Chara paid particularly close attention, but not to the explanation at all. "Made by Dr. Gaster, yada-yada. Power source for the entire Underground, blah-blah. Thermal energy." Was all they really got from it.

No, they were more interested in the monsters. What made them tick and how they worked. Maybe, if they were lucky, they would have a chance to push at some of their buttons.

The weird short Skeleton made science related jokes and puns throughout the presentation to entertain the class, and for most of the simpler minded children, it worked. But Chara didn't care about that.

All the while, the Cat, named "Gaine" made more subtle plays. Commenting on the machine and seemingly pointed jabs at the smaller Skeleton, apparently named "Serif."

There was a particular time, Gaine mentioned that the inner workings of the CORE still had to remain classified, because they didn't want any greedy information hogs to run off and spread it around. He said it calmly and evenly, but Chara noticed the lilt in his voice and the very sly look he slipped Serif. The Skeleton laughed about it, saying that there was no way that could ever happen, because Dr. Gaster's security measures were the best.

As if waiting for a cue, Chara raised their hand.

"But what if there's a security breach from the inside?"

Gaine raised an eyebrow and a very subtle smile pulled at one of the corners of his mouth.

"Oh, I'm sure Dr. Gaster would notice anything strange going on with his assistants. We go through a rigorous screening process before we're hired on."

"But what if they say all the right things just to pass the screening and get in and then get information that way?"

Gaine gave a slight nod. The perception skills on this strange child were exceptionally on point. Hm. For a human. At the very least, this kid, an unbiased third party, was voicing this aloud with Gaster present. It was almost a perfect set up. Enough to plant the seeds of doubt within the doctor.

"None of us would ever do anything like that." Serif winked, "We know how important the information is and how much everyone depends on it. We all care about you guys too much."

"Besides," Dr. Gaster added, "Just like Mr. Gaine said, I keep close tabs on my operations. If there was any funny business going on, I would know."

Chara shrugged, shoving their hands in their pockets. "Just saying. More people means more liability. Can you ever be 100% sure that there isn't a mole?"

"Alright, kiddo. That's enough on the conspiracy theories for now." Corbel stepped in with a dismissive smile, placing a hand on the kid's shoulder. "Does anyone else have any questions for Dr. Gaster, Mr. Serif, or Mr. Gaine about the CORE or how we use it every day?"

Once the questions were done, it was time for Corbel and his class to leave. As they were preparing to go, the kids said their final farewells to the other assistants. They even got a few hugs from Baelin. She stepped back with a wide smile. She stood with Maltez, leaning in and whispering something to him. If possible, Maltez's already wide eyes went even wider, but his expression settled into a smile as well as he thought whatever it was over.

Corbel made his own rounds, saying goodbyes to his old coworkers, and being sure to make plans with his father.

He wanted to go say goodbye to Sans as well, but the assistant was surrounded by kids who enjoyed his jokes. They asked him to repeat their favorites, or explain the ones they didn't quite understand. Many thought that the jokes would even help them on the next quiz. Corbel had to smile at that, settling for a quick wave to him when he looked up and happened to catch his eye for a moment. Sans smiled and waved back.

Conclusion, the lab visit was a success.

---

That just left the attempt to make amends, which was also a request from Toriel. To make up for what happened in the Echo Flower room, she invited Corbel's class on a field trip to New Home and specifically to their home. She said she would be cooking for the class and Asgore could show them the garden. It would be a good opportunity to learn about plant life and all.

After it was approved by the school, Corbel made the arrangements to make the field trip happen. It really was a pretty nice opportunity and one that didn't really come along often. Corbel remembered once, when he was maybe four, he came along with his father when he made a report to the king. His mother was busy or something, so it was up to Dr. Gaster to watch their son for the day. During their visit, Corbel was allowed to play in the garden. He didn't quite understand how special it was at the time, but he was able to briefly feel the sun and see its light shining in on the flowers. It really was a treat.

One that he could now share his class.

As they visited, Corbel and King Asgore (who, of course, told the children to refer to him as "Mr. Dreemurr") taught the children about the science known as botany. They taught the children about how plants could make their own food by soaking in nutrients from the soil and light from the sun. The children were even taught a song to help them remember the process.

There was a low muttering, coming from a certain child saying that learning the song or really anything about flowers was pointless if they were going to be living in the Underground their whole lives. And if they wanted to learn about flowers and gardening, they needed a way out to see where the flowers really were.

Only a few people heard this. Corbel and Asgore were not among those.

For lunch, sticking with her pie based specialties, the Queen made a quiche for the class. At first, the kids were surprised and excited that they would be having pie for lunch, but were even more surprised when they learned that the pie wasn't sweet. There were mixed reactions, but for those who were not too fond of the quiche, there were sandwiches and fruit prepared.

As the day wore on and the experiments were underway, the students separated into groups as they usually did. For a change in pace, the Dreemurr kids separated and each found a different group to work with. It was good for them to make new friends after all and not just isolate themselves within their own trio.

This worked well for two of the three children. The third, again, found no interest in the study and care of plants and stayed to themselves or found small pebbles to chuck at the other kids. He pegged Asriel in the back of the head a couple of times and hit Alia's leg as well. Of course, when they turned around, he pretended to be at work with the rest of his group, analyzing the soil samples and comparing them.

When the experiment was nearing its conclusion and the trip's Free Time was starting up, Chara presented his group with a suggestion to do something really cool. The other students were excited to see what he could be talking about. Chara told them to be quiet and to follow behind him.

As they all snuck away from the rest of the group, through the door to the back of the throne room, it caught the eye of Asriel who grabbed Alia's sleeve and gestured for her to follow. They snuck away as well, avoiding the eyes of anyone who could be watching.

They followed the group past the final room and into the hallway, to a door blocked by a few chairs and a poster paper sign.

"CAUTION: KEEP OUT! TESTING IN PROGRESS!"

At the sight of the sign, one of the students became apprehensive, doubting the safety of this venture. Chara grinned, assuring them that there was no one inside. The testing was gonna start later. He called the student a chicken for good measure . . . which wasn't inaccurate considering their Avian features.

The student frowned all the same, baited by the insult as they pushed through the chairs and into the next room. Alia and Asriel followed them.

Just past the door and in the next room, they could feel an immensely strong presence. An aura that seemed to physically push them away. It radiated power and pulsated as if it were a living thing. Solid and stable enough to feel like a brick wall right in front of them.

The barrier.

The students halted, staring open-mouthed at the thing, the overwhelming strength of the barrier's aura crashing over them in an intimidating wave.

Another student clutched at their chest as that wave hit and they doubled over as if a physical force was keeping them down.

The two other students could feel it too. It was as if the solid wall of magic was just too strong for them to handle and it kept them down, unable to approach at all.

Chara, on the other hand, stepped forward, unwavering and without laboring in the slightest. It had no power over his ability to approach like it did for the other children. Huh, so it was just monsters who couldn't approach. When they first came here, Asriel had a similar reaction to the barrier as these kids did. Frozen, unable to move forward. But . . .

Chara held out their hand for one of the students. "C'mon, let's touch it!"

"T-touch it!?" The first student stammered, "I-I don't think that-"

"Oh, c'mon, you scaredy cat! Look! It doesn't even hurt!"

Chara reached back out with their other hand toward the wall to demonstrate. Their fingers seemed to stop when they reached a certain point. There was a spark of light that created a rippling effect across the barrier's surface when his fingers made contact.

"Just hold my hand." Chara instructed with an almost irritated groan. "You should be able to at least get this far if you're touching me."

The student gave it a try, reaching out to touch Chara's hand. Immediately, that crushing wave seemed to pass and they were able to stand without laboring. So strange . . .

They stepped forward and reached out and were, indeed, able to touch the solid invisible wall of the barrier.

"Wooooaaaahhhhh . . ."

"Cool, right?"

"I wanna try!" Called one of the other students.

The remaining students switched off to touch the barrier, and just like the first, they needed to be touching Chara in order to do it.

"Now, you wanna see something even cooler?" Chara pushed, "Alia! Come here! I know you and the Prince followed us!"

The other students gasped, caught, and immediately concerned that they might get tattled on.

When she was called, Alia stepped out from where she and Asriel were hiding out near the entrance to the room. She had her arms crossed and a bit of a frown in place.

"We're not supposed to be down here, you know!" She pushed, "The guys from the lab are supposed to be testing today, remember!? You're gonna get us in trouble again!"

"Okay, okay, fine! Just this one thing and then we'll head back! C'mon. I promised these guys something cool! Don't make a liar out of me now! C'mon. Touch the barrier with me."

Alia rolled her eyes, stepping forward and showing no sign of being impeded by the barrier's force at all. With a groan, she reached out to touch the barrier. Just like when Chara touched it, a spark of light emanated from her hand and rippled outward toward the outer edges of the wall. At the same time, a shimmering effect surrounded Chara's hand on the barrier.

The students behind them "ooooh"ed as they watched.

The effect got even greater when Alia and Chara held hands. The light around their two hands on the barrier shone even brighter and the ripples became more noticeable and slightly more turbulent, soon, the barrier looked like it was vibrating, the energy that was keeping it stable was fluctuating.

"Well, that is interesting." Said another voice from behind them. "It seems the human children are able to shift the integrity of the barrier just from being in close proximity. Not only that, but it seems as if there's nothing impeding them from approaching it."

The students gasped at the voice and spun around.

"Mr. Gaine! Mr. Serif!"

"Um . . . hi?" Prince Asriel nearly squeaked with really nothing better to say.

"Alrighty, kids. 'Fraid the fun's over." Sans spoke up after jotting something down on his paper. "You guys shouldn't be down here. You guys are smart, I know you can read. So, you kids wanna explain what part of 'Keep out' was so confusing?"

"The barrier's not dangerous." Chara contested, "Asriel, Alia, and I have been here loads of times and no one's gotten hurt yet. We just thought it would be more fun than stupid science experiments with stupid flowers. This sounded way less boring. And guess what? It was."

"That's not the point!" Sans stepped forward while Gaine was busy parking the dolly carrying a few energy canisters, "We're in the middle of an experiment right now. It's not safe down here for you kids today. If you guys got hurt . . ."

"Then it would be tracked back to you." Chara chided, fully leaning against the barrier now, "It would be because of your experiment. Or maybe it'll be pinned on the neglectful Mr. Corbel who lost track of his students on a field trip."

Sans glared heatedly at the kid. "Nope. That's not gonna happen, kiddo. Because all of you are coming with me to see Queen Toriel, King Asgore, and Mr. Corbel right now."

"Sans!" Alia protested, "No, we were just . . . Chara was . . . We're sorry. Please don't tell Mom and Dad!"

"I'm sorry too, Alia, but I really can't let it slide this time. You guys could've really been hurt!"

Without hesitation, Sans continued forward, the force of the barrier having little effect on him, as he reached out for the children.

The moment he touched them, taking each child by the shoulder, there was an immediate reaction. It was like a flare gun had been shot directly at the barrier. An almost blinding flash of light hit the wall and waves danced across its surface. A thunderous clap accompanied it as the barrier fluctuated like never before.

The three closest to the barrier were thrown back, only Sans landing on his feet. The other two groaned and pulled themselves to their knees, clutching their chests, where surely their Souls were finally starting to pulse at their normal pace after synching with that blast.

Sans held his chest as well, his posture hunched as he stared pointedly at the barrier. He felt the punch to the Soul as well and the moment it seemed to punch back. What the hell was that!?

"God . . . damn it." Chara muttered, pulling himself now to his feet, "The hell just happened!?"

Alia stayed on her knees, shocked into tears. The blast really did hurt and it felt like it stopped her heart for a second. More than anything, she was shaken at how suddenly it all happened.

Gaine, Asriel, and the other students witnessed the blast as well, the students screaming in their surprise and shielding their eyes from the light. Gaine squinted, but saw the entire thing, even picking up on something that the others wouldn't have noticed even if they did see what happened.

The moment all three souls flashed for a split second upon contact with the barrier, each shining with a different color.

When the light died down, Gaine stared at Sans' back. Another piece of the puzzle falling into place.

Within moments, more footsteps flooded the area as Toriel and Corbel rushed into the barrier room. Both stood forward, surveying the scene.

"What happened here!?" Corbel demanded, seeing several of his students huddled in surprise and fear, the Dreemurr kids stumbling over themselves as they tried to stand, and Sans hunched over, clutching his chest.

Toriel looked over the scene as well and saw all three of her children along with some of the students visiting for the field trip. Were they involved with whatever that loud blast had been!? What was it that made that noise!? Were any of the children hurt!?

When her prodding eyes locked with Chara's, he froze, his expression widening.

"Oh, shi-"

"Well!?" Toriel ordered, her tone and her expression hardened, "Somebody start talking! Right now!"
