Undertale – Aftermath

Chapter 6: Frisky

DISCLAIMER: Undertale belongs to Toby Fox.


*Later that night...

Asriel and Frisk is sitting on the couch in front of the TV, relaxing after the dinner party.

The room is still filled with colorful decorations set up by Mettaton, "We have to clean this tomorrow." Toriel looks around the room before picking up the dishes on the table, "I will clean the plates, and you to should go to sleep, it's nighttime." and then she heads out to the kitchen.

Asriel sighed, "That's one party." he patted his stomach, "The burgers were great."

"Thankfully." said Frisk while they play around with a balloon.

"Yeah..." Asriel leans back to the couch, "From what I hear, dad is preparing the kingdom to go up to the surface." and turned his head to Frisk, "And they're considering you to be their ambassador."

"Me?" Frisk came up with a rather surprised expression.

"Well, you're the only peacemaker we know so far." Asriel raises his shoulder, "If we're lucky, we could meet more people like you."

Frisk looks down, thinking something, "But I'm still a kid."

"Well, we need to learn how to live peacefully with the other humans, somehow." Asriel scratches, "Gosh, this kingdom business is making me dizzy." then stands up from the couch, "Let's just go to bed."

The both of them returned to their room, decided to hit the bed.

Asriel looks out to the window, there he can see the night sky over the cave where the barrier is used to be.

"I wonder what's up there, in the sky?" he mutters to himself.

"Stars." Frisk replied, standing beside Asriel.

Asriel put up a weak smile, "Chara told me once that she used to like staring into the sky, seeing shiny little dots and a big white circle."

"The moon."

"Right, that was the name."

They stared at the sky in silence, enjoying the cool breeze that came from the outside, before Asriel breaks the ice,

"So, uh, I promised you to tell more about Chara, right?"

Frisk simply nods.

"Okay." Asriel clears his throat, "Chara fell to the underground just like you, and I was the first one to found her lying on a bed of golden flowers."

Asriel began to tell the story of his childhood.

"She was hurt from the fall, but fortunately the flowers can reduce the damage she took. I brought her to the castle where mom healed her with her magic."

"From then on, we became siblings. Or best friends, more like."

"The kingdom was still not that big at the time, New Home was not built yet, and the Core is still under construction by Gaster, the royal scientist at the time."

"Gaster?" Frisk cuts off Asriel' story.

"Yeah, he's the one who built the Core to provide electricity. But after finishing his work, he just kinda... disappeared. No one ever saw him since." Asriel replied.

"I met Gaster."

"You what?" Asriel asked with confuse.

"Entry number seventeen." Frisk grabbed their phone and began to playback a strange recording they caught, it's a video full of symbols, hand symbols. Coupled with an eerie background ambient and a rambling in unknown language by a male voice.

"W-well, that's pretty creepy." Asriel stares into the phone screen, "Where did you get this."

"Alphys." Frisk replied simply.

"Uh, so the thing when you met Gaster? Where did you met him?"

"A room in Waterfall."

"A room? You mean in some kind of building?"

Frisk shook their head, "A door on a cliff."

Asriel scratches the fur on his head, "I don't really know what to say..." and the pauses for a moment, "The underground IS full of magic anomalies, but I'm not really convinced of this one."

"Did someone said anomalies?" Sans appeared in front of the window, startling both Frisk and Asriel.

"Ack, what are you doing here?" Asriel jumps backward.

"The talk about this Gaster fellow pique my interest." Sans replied.

"So, what kind of topic are you bringing up?"

"Well, first of all..." Sans put up a serious expression, "Do you know the team that helped W.D. Gaster built the Core? I was part of it."

"I didn't know you're a scientist."

"Well, technically, I'm not." Sans paused for a moment, "I just gave out advice about quantum physics."

"How do you know stuff about quantum physics."

"Book, of course." he continued, "Alphys is also there to help Gaster with engineering, and the construction site is guarded by Royal Guards, Undyne included."

"Papyrus was still trying to join up the Royal Guard at that time, and Undyne is purposefully stalling him, so that he doesn't get in the way."

"I see your point on that I think." Asriel raises an eyebrow.

"Well, you know how my brother is." he sighed, "He's actually pretty strong, but he's too damn kind to become a Royal Guard. He'll die as a smiling pile of dust if he's actually posted on fighting."

"Demands on building the Core is overwhelming, and expectation from the people are pretty high. The rest of the team were convinced that Gaster was suffering from stress with all the pressure." Sans raises his finger, "And on the day it was completed, he vanished..."

"Swallowed by his own creation." Frisk continued Sans' statement.

"Then you heard the rumors." he pauses for a second, "You guys wanna know the truth?"

Asriel and Frisk simply nods in curiosity.

"Gaster may be a brilliant scientist, but with all the demands, his mentality is unstable. And so, Alphys did not only helped him in engineering, but she also works for his counselor. You know, to keep him in line."

"But when Asriel died in the hands of the humans, Asgore commanded Alphys to research on how to enhance the monsters so they can have as much DETERMINATION as the humans have. With Alphys busy on the task, no one can keep Gaster in line."

"Not even you?" asked Asriel.

"What, do you think a barrage of bad puns would help the man in his instability?" Sans winked.

"No." Frisk replied.

"Guess not." Asriel raised his shoulders.

Sans paused for a moment, "Now, most people believe Gaster' disappearance was an accident, but in reality, he actually had a plan for "Another Life". And at that point, I believe he already went insane."

"After Gaster found out about Alphys research on DETERMINATION by injecting it to monsters, Gaster has his plan completed, and all he has to do is to get some sample."

"Creepy when you put it that way..." Asriel shrugs off some uneasiness from him.

"Frisk." Sans turns his head to the second fallen child, "You know those monster, right? The ones that resides deep inside the Lab."

"Amalgamates." Frisk nods their head.

"A what?" Asriel asked with confuse.

"Those are the test subject Alphys used, even though she tried her best to keep them a normal as possible, things didn't go as planned." Sans shook his head, "Good thing you can set them up straight, Frisk." Sans gave Frisk a thumbs up, "They owe you one. Well, we all did, I guess."

"When the Core was completed, the whole kingdom was dumbfounded about Gaster' disappearance, and the next generation of monsters merely know him as an urban legend, or a myth, if you will."

"Well, he isn't, is he?" Asriel asked.

"My theory is, Gaster purposefully jumps into the center of the Core because he knew it had a chance of not killing him."

"How is that?"

"Before beginning his so called new life, Gaster injected himself with dozens of DETERMINATION, upping his chance of surviving being torn apart by the machinery particle by particle, atom by atom, and the result is quite surprising."

"He survived, but with a different state. And so he is now." Sans sighed, "Don't know what's he doing out there, but if I know Gaster, I know he's planning something, probably something horrifying now that he's -in a quote- alive." Sans gestures his finger to mimic the quote marks.

"Now, I know my story is pretty crazy, but THAT story trumps mine in like, almost every way." Asriel extends his arms sideways.

"At least you're not a flower anymore." Frisk smirked.

"Ha ha, pretty funny."

"Welp, that's all I can say." Sans took a deep breath, "Shouldn't you two go to bed now?"

"Golly, how long have we been talking?" Asriel take a look at the clock on Frisk' phone, "It's ten o'clock, underground time." he then walk into his bed after handing back Frisk' phone, "Better go to sleep."

"Right, I'm going home, then." Sans puts his hood on.

"Good night." Frisk smiled at Sans.

"Good night, kid." before turning away, he grabs Frisk hands and held them on his own, "Be safe, alright?"

Frisk closed the window and the curtain before retreating to their bed, only a table with a lamp that separates theirs and Asriel' bed.

*A few minutes later...

"Boy, I can't sleep." Asriel said to himself, then he turned his head to Frisk, who is moving restlessly.

Frisk opened their eyes, they stared back at Asriel.

"You can't sleep, too, huh? Seems like we had a lot of trouble sleeping since you shared your SOUL with me."

"Weird dream?" Frisk asked behind their blanket.

"No, not yet." Asriel replied as he stares into the ceiling.

A somewhat uncomfortable silence fills the room, there are no noises at all except the wolves who are usually howling at night.

"Hey." Asriel called out, and Frisk simply turns their head to face Asriel.

"I'm just curious, I knew Chara' gender because mom told me when she's healing her wounds, but..."

Realizing Asriel' intention, Frisk cheeks grows pink.

"I never known your gender, Frisk. Not even one of us monsters knows since you fell here, until you saved the whole kingdom from, well, me." Asriel pauses for a moment, "So to put it plainly, what is your gender? I just wanna know."

"G-Girl..." Frisk replied quietly.

"Uh, sorry, I didn't hear you, what was that?"

"I'm a girl!" Frisk repeats HER statement, albeit with an elevated tone.

"Whoa, okay, calm down, sorry if I hit a sensitive spot there." Asriel sat up, rubbing the back of his head, "Maybe you just don't like to talk about it?" then thinks to himself, "Or maybe you're just really shy."

Frisk gave Asriel a somewhat irritated stare, with her face blushing red.

"Ah, okay, I'll stop." Asriel lies back down, pulling up his blanket, "Thanks for telling me, that's all I need to know." he pauses before giving Frisk a big smile, "For now." and covers himself with his blanket.

Frisk decided to bother Asriel even though he somewhat helped took a burden off her chest.

"Can I ask you a question?"

"Yeah, what about?" Asriel responded quickly.

"Did you use magic to... grow?"

"Oh, you mean that transformation back when you fight me? Well, you do know we monsters might don't have as many DETERMINATIONS as you humans have, but our magic is stronger than yours."

Asriel continued, "And I heard from Alphys that your kind has discarded the use of magics completely, and replaced them with technology."

"Can you teach me magic?"

"Depends on do you have what it takes or not. You need a large pool of SOUL magic in order to use them as powerful as ours. But I think both you and I has weaker magic potential now that we each has half the power of a SOUL."

"Let's restore them?" Frisk asked with an uncertain tone.

"Do we know how?"

"Ask Alphys."

"Makes sense." Asriel pauses for a while, "Maybe she know the way on how to restore my magical energy, and yours, too, maybe, if you had one."

"By the way..." Asriel smirked, "Why do you need magic for? Do you wanna grow like me, too?"

"I don't know..."

"Well, we can be together like mom and dad once we're grown up, right?" he smiled at Frisk whose face is blistering red.

"Golly, you're red." Asriel stared at Frisk for a while, before she covers herself with her blanket.

Asriel chuckled at Frisk newfound behavior, and now that he knows, they might be able to fully recover after all.

*Meanwhile...

"Yes, this will have to do." a white figure wearing a black coat is pondering on some kind of machinery.

"With this new extractor, I can finally found a way to resurrect that child." he grabbed a nearby screwdriver and seems to be fixing some kind of a pipe leading from the machine into yet another machine.

"All I need is to finish this contraption, the next step will have to wait." he tampers with the pipe for a moment before a steam startled him, "Argh, blasted pipe!"

After a while, he steps back from the machine and observed it, "My purpose shall be fulfilled." he then stares into his cold, pale hands, "Where are those two when I need them..."

"No matter." he shook his head, "My new partner will be reborn sooner or later." he then left the area after materializing some kind of portal out of nowhere.


That's all for now, folks, because I have BIGGER plans for this Fanfic, so don't you worry.
