"Tra la la..." River Person sang as we went along back towards Undyne's house, sitting on the sides of the boat and looking out at the passing water.

"Beware the phantom of the past." they said, and my eyes widened.

I glanced over at Frisk, who looked somewhat confused by their words.

River Person looked over their shoulder at me, and I caught a light orange glow from the right side of the shadows in their hood. Perhaps their right eye?

They turned back around without another word.

Frisk looked over at me, narrowing their eyes in question.

I shrugged, sweating nervously.


"Nyeh, good! You've made it right on time!" Papyrus greeted as Frisk and I stepped into view.

"Here, give her this." Papyrus handed Frisk what seemed to be a...

Stuffed bone?

Mmmkay.

"She loves these!" Papyrus grinned, knocking on the door.

The door opened, a smiling Undyne answering.

"Alright, Papyrus! Are you ready for our super secret one on one training?" She asked. "After today, I could really use something to..." Undyne's eyes widened as she saw us standing behind Papyrus, her smile remaining though her eye twitched.

"Hello Undyne! I hope you don't mind that I brought some friends with me!" Papyrus said with that convincing smile of his.

"Why don't. You guys. Come in..?" Undyne said through gritting teeth.

Papyrus, Frisk and I entered, Undyne trying and failing at not slamming the door behind us, making me flinch.

Frisk handed her the toy, and she looked at it for a moment, arching a brow.

"Uh... Thanks..? I'll just... Put it with the others." She walked over, opening a drawer and placing the bone inside.

Papyrus gave Frisk and I a thumbs up as this happened, before looking to be thinking as Undyne came back.

"Well... I have to go to the bathroom." Papyrus proceeded to get a running start, jumping out through the window.

"Eh-" Undyne rose one finger in protest, but he was already gone.

She sighed, closing her eyes for a moment.

"So... What are you two doing here?" Her eyes narrowed. "Come to rub your victory in my face?"

"Go ahead, say it..." Undyne looked away. "Tell me I'm a failure. I couldn't even save that kid."

"Monster Kid's alive." I said, and her eyes widened.

"What?"

"What, you think I dove down that hole for nothing?" I smirked, shrugging.

"But how did you save him?" Undyne asked, arching a brow. "Actually... How the hell did you survive?"

"With enough DETERMINATION, anything is possible." I shrugged.

"... I still think you two are stronger than you let on." Undyne's eyes narrowed.

"Nope, we're as weak as Waterfall is blue." I've always been pretty good at lying.

"So, what? If that's not why you're here, then why?" Undyne said, arching a brow. "Oh, wait, let me guess! You wanna be friends, right?"

Frisk nodded, smiling.

"Wonderful! I accept!" Undyne said in an obnoxiously loud voice. "Let's all frolic in the fields of friendship!"

"That was easy." I muttered.

"NOT!"

"Yeah, that makes more sense." I muttered again.

"I would NEVER be friends with you two! You're the one standing in the way of everyone's hopes and dreams!"

I started humming Hopes and Dreams and Save The World and Frisk quickly caught on but said nothing.

"In fact, if you weren't my house guest, I'd be pounding you into the dust right now!"

"You're very polite for someone who was trying to kill us fifteen minutes ago." I said more to myself, but Undyne shot me a glare.

"Oh, don't think I forgot about your throwing mud in my face stunt!" Undyne grabbed me by the collar of my shirt, yanking me up.

"Eep!" I said cowardly as she yanked me up.

"So stop your comments and your humming, or I'll knock your lights out!" She threatened, and I nodded, raising my hands and sweating nervously.

She dropped me, and I landed on my feet.

"Dang! Too bad!" Papyrus said from the window.

"I thought Undyne could be friends with you two. But I guess..." Papyrus paused for dramatic affect.

"I overestimated her." Papyrus shook his head with disappointment. "She's just not up to the challenge."

"WHAT?! Challenge?!" Undyne questioned. "Papyrus, wait..!"

"Darn it!" Undyne stomped once. "He thinks I can't be friends with wimps like you two?!"

"Listen up, humans." Undyne seethed with DETERMINATION. "We aren't just gonna be friends..."

"We're gonna be... BESTIES!"

I cringed even more hearing her say it out loud. Something about the term 'besties' just... Ew.

"I'll make you like me so much... You won't be able to think of anyone else!"

"Oh boy." I said with minimal sarcasm.

"It's the PERFECT revenge!"


They laughed lightly as they watched Cter fall back out of his chair when the spear broke the table in half, Undyne demanding they stay put.

"You're more of a lurker than me, kid."

"Don't you have something else to do?" Chara arched a brow at Sans as they turned around.

"Well other than take a nap, nope, I don't think so." Sans shrugged. Now that he mentioned it, he did look pretty tired.

"So uh, what exactly is the end game plan here? Just watch creepily and then try to cut the kids when ya feel like it?" Sans arched a brow.

Even though he didn't have one.

Skeletons, dude.

"I don't have to tell you anything." Chara said, crossing their arms.

"Yep, but chances are I'll figure it out eventually." Sans shrugged. "I'm pretty perceptive, y'know?"

"So how 'bout we just cut to the chase and you tell me what your plan is." Sans suggested. "And then I'll try to convince you not to do it, you won't listen, and it'll be great."

"Sounds boring. I think I'd rather have you keep guessing." They began to leave, but Sans rose a hand, signalling them to stop.

"Hold up a sec, kiddo." Sans said. "Last time I tried to talk to ya you left rudely, so I'd like to try to convince you one more time."

"You must be pretty desperate, huh, Smiley Trashbag?" Chara grinned over their shoulder at him.

"You and the Flower really do share some similarities, huh?" Sans glanced to the side with his grin.

"But as much as I hate to say it, and I really hate saying it, trust me." Sans pupils disappeared. "You and I both know you're pretty good wit that knife. And we both know you hate dying." Sans grin widened.

"So if any of us are gonna survive, you're gonna have to help." Sans said, and once again they began laughing lightly, shaking their head.

"I think I would rather die then work with you. Especially for something to benefit you." They turned around once more.

"If they get in my way, I'll kill them. I don't care what happens to you."

"They'll obliterate you, kid."

Chara stopped in their tracks.

"What was that?" They looked over their shoulder, eyes narrowing.

"D-d-d-d-d-d-did I stutter?" Sans stuttered jokingly, and they growled angrily.

"I think you've forgotten just how strong I am." They smirked, right eye glowing red.

"I think you've forgotten that you aren't the strongest thing out there." Sans' left eye glowed blue, a gust of wind blowing between them.

"And here I thought your last failure would have taught you that."

Sans disappeared as they snarled, shooting off at him and stabbing nothing but thin air.

"Touchy." Sans said, looking to the side as he grinned.

He looked back up, eyes widening to find them coming down towards them, knife pulled into the air.

"Uh oh..."

The sound of a door slamming was followed by a solid thud.

Chara flipped in air, skidding on two feet with a bruise already forming on the side of their face.

"Aw man, my hand's all numb!" I looked at my hand, shaking it once or twice. "Guess that's why I'm more of a range guy, huh?"

"Oh, hey kid. I thought you were busy with Undyne." Sans said casually, looking over at me.

"Oh, Frisk is distracting them by pointing at them with the spear." I shrugged.

"Are you... Hitting on me?" I heard through the wall, chuckling.

Chara readjusted their jaw, shooting a glare at me.

"So, I see you're still creeping around." I looked back to them. "Which is cool, you do you." I shrugged.

"But if I catch you trying to cut up one of my friends again, my buddy friend guy pal amigo hombre brother sister chum fella," a red coat of color passed over my left eye for a second.

"Well, I might have to get not so friendly with ya." I shrugged.

Their eyes narrowed at the sight of my left eye, grinning lightly as they backed away into the shadows.

"Fair enough." As they faded into the shadows, only the red glow of their right eye and their grin became visible. "But you two should know..."

"I'm always watching."

"I feel like they're quoting someone." I said, though I obviously knew who they were quoting.

"Well, don't worry kiddo." Sans winked one eye shut. "I'll keep an eye out."

"Sans... You look exhausted." I said with minor worry.

"What, me?" Sans grinned sleepily, glancing to the side. "C'mon kid, you know I've got a lotta stamina."

"Sans, if you had a lot of stamina, I wouldn't have magic." I frowned, placing my hands in my pockets.

"You should go home and rest. We can handle ourselves." I placed a hand on Sans shoulder.

"Heh... Alright, kid. For you, I'll-" Sans yawned. "Do it."

"Good. And don't worry." I smirked. "I'll keep an eye out for the ghosty."

Sans teleported away, and I turned around to walk back into Undyne's home.

"Man..." I rubbed my left eye. "My eye hurts..."


"M-maybe I should call Undyne..." Alphys said, sweating nervously as she watched Sans teleport away and Cter walk back into Undyne's house.

"That other human is clearly violent towards more than just the other humans... And Sans clearly knows more about them than he leads on..." Alphys gnawed on her thumb nail, thinking.

"T-they could try to hurt Undyne when the others are gone... Or even when they're still there... Then what would they do..? Would they leave Undyne there? The magic one seemed very DETERMINED to keep his magic a secret..."

Alphys slowly reached for her phone.

"I wouldn't do that if I were you."

Alphys stopped dead, eyes widening in fear.

"I'm not very fond of tattletales, Doctor." Chara grinned, holding their knife in one hand and pressing the point against the opposite finger.

Alphys could feel her heart pounding in her chest, glancing at them out of the corner of her eye.

"You know, I don't get to see you face to face very often." Chara said, looking up in thought.

"W-w-what are you t-talking about? W-we've never met face to face..." Alphys shakily grabbed her cup.

"And here I was hoping you too would remember... Oh well." Chara shrugged. "I guess you're just too stupid."

Alphys noted the bruise on the side of their face. She didn't know ghosts could get those. Or get punched.

"W-what do you mean..?" Alphys grabbed her mug.

"Oh, it's nothing. I'll tell you some other time. If I get bored." They shrugged. "But I suggest you keep my existence to yourself..."

Alphys's eyes widened, Chara appearing behind them.

"Or else I'll have to make you keep quiet."

Alphys screamed, turning around quickly and swinging her mug at Chara, who jumped back, landing on top of her screen.

"We really don't talk often enough." Chara shook their head. "I'd almost forgotten what you were like..."

"How easy you are to scare..."

"So, I'll keep this simple." They jumped down, landing on a stack of paper on her table.

"You keep quiet. About me and Cter's magic." Chara twirled their knife.

"You do that, and I won't stab you. Until my plan calls for it, anyway." They muttered the last part.

"Capiche?"

Alphys nodded shakily.

"Good." They disappeared.

Alphys say there, hyperventilating. One hand over her heart, tears built in the corners of her eyes.

Alphys jumped at the sound of her phone going off.

"H-hello?" She answered shakily.

"Hey Alphys." She was somewhat relieved to hears Sans on the other end.

"So, I'm guessing you saw my little uh... Encounter in front of Undyne's house."

"Y-y-yeah, I did..."

"Well, I'm going to take a nap. Tell me if anything goes down with the little creep, alright?"

"Y-yes, okay." Alphys nodded.

Sans hung up, and Alphys buried her face in her hands.


"Are you sure this is the best place for a fight?" I said over the crackle of the flames.

"What, are you scared? Fuhuhuhuhu!" Undyne laughed obnoxiously, holding one spear.

"Go on, you can have the first move!"

Frisk and I glanced at one another, clicking ACT as the four buttons appeared.

We both clicked *Fake Hit at once, jumping forward and roaring as Undyne prepared herself.

We really made it convincing.

We stood there, eyes wide as our fists hit a brick wall in Fish Woman form.

A small -1 appeared above Undyne's head.

"... Is that it?" Undyne said, face showing confusion and surprise.

"Even attacking at full force... You just can't muster any intent to hurt me, huh?" Undyne sighed, glancing to the side.

"Heh... you know what?" Undyne dropped her spear.

"I don't want to hurt you either." She closed her eyes in defeat.

"At first, I really hated your whole saccharine schtick, but... The way you hit me just now..." Undyne looked up in thought.

"... Reminded me of someone."

"Now I know you two aren't just some wimpy losers." Undyne gave a large smile. "You're wimpy losers with big hearts!"

"... Just like him." Undyne's smile faded.

"Listen humans." Undyne said seriously. "It seems that you and Asgore are fated to fight."

"But knowing him... He probably doesn't want to." Undyne almost rolled her eyes.

"Talk to him. I'm sure you can persuade him to let you go home."

"Eventually, some mean human will fall down here. And I'll take THEIR soul instead!" Undyne said.

"Sounds good to me." I shrugged, and Frisk elbowed me lightly.

"Oh, and if you DO hurt Asgore..." Undyne frowned. "I'll take the human souls, cross the barrier, and beat the hell out of you!"

Frisk and I nodded.

"That's what friends are for, right?" Undyne grinned.

"Now lets get the hell out of this flaming house!"

Undyne proceeded to pick us both up, jumping out the door.

"Well, I'll be at Papyrus's house." Undyne said after a moment of conversation.

"Ya sure you don't wanna go house hunting?" I questioned, arching a brow.

"Keep it up, punk." Undyne said, eyes narrowing in a 'Just about done with your sh!t' face, and I proceeded to step behind Frisk.

Undyne laughed, sprinting off.

I glanced over at the Dummy sitting quietly in the corner.

Glaring at us.

"Uh..?" I arched a brow at it.

"What. What?! WHAT?!" Mad Dummy said angrily.

"... It's a living."


I laid on my back on River Person's boat, yawning.

"Well, that was exhausting." I said, Frisk nodding from their place at the edge of the boat, feet hanging off as the boats legs kicked up water.

"We could stop by Snowdin and rest at the Inn, if you want." Frisk suggested with minor worry.

"Nah..." I yawned. "I'll be fine."

Judging by how my sleep had been going lately, I didn't want to be greeted with another horrid nightmare.

"Too late." River Person chimed in, pointing ahead to Snowdin.

I looked mildly disgruntled, River Person playing it off with a Tra La La.

"Get your sleep, Tra la la~ It's very important." They not so subtly hinted.

My eyes narrowed as I stared at the back of their head.

"... Who are you..?" I muttered to myself.

"Thanks River Person!" Frisk said, smiling.

I grumbled to myself, yawning.

"Fine, since Frisk clearly needs sleep." I glanced to the side.

"You're always thinking of me, huh?" Frisk joked, nudging me.

I smiled lightly, bags forming under my eyes.

Their eyes narrowed at the sight.

The last time they'd seen me this tired...

"Just keepin' myself sane."

frisk frowned lightly, shaking the memory off.


"Well, this is different."

We sat across from one another on a field of golden flowers.

"Well, I don't feel like cutting you this time." Chara shrugged.

"That's about as kind as it gets with you, eh?" I arched a brow.

"I'd like to remind you that you're usually the one who gets hostile first." Chara argued, and I shrugged.

"I told ya before..." I closed my eyes. "Old habits die hard."

"If you really believe that, why do you trust Frisk so much?"

"Are you seriously at that again?" I rolled my eyes.

"Think about it, Cter. They gave me their soul to bring the world back. And you know what they did right after that?" They grinned.

"They chopped them all down once again."

"Didn't even try to undo what they did." They shook their head.

"It wasn't me who started this, I just played along with their rampage." Chara said, smirking lightly as they sat back, bringing up one knee and resting their arm on it.

"I mean, what choice did I have?" they were surprisingly good at pulling off the innocent look. "They would have killed me too if I didn't play alo-"

"That's enough." I rose one hand, eyes closed.

"You know what your problem is?" Chara grinned.

"I don't listen, whatever." I rolled my eyes.

"Oh, you do remember!"

"I remember everything, yes." I said, looking to the side. "But you don't listen either." I said, and their eyes narrowed.

"I told you that DETERMINATION makes your skull thick. That's one of the reasons I don't listen to you, too DETERMINED for your BS." I said, sitting back on my hands.

"What you just said was a load of BS." They rolled their eyes.

"heh, maybe so." I shrugged. "But here's something less... Full of crap-y."

"Absolute power corrupts absolutely." I rose one finger as I spoke, eyes closed.

"So I don't blame Frisk, it gets boring doing the same thing over and over again, and with that power... Well, you're gonna get corrupted eventually." I shrugged, opening my eyes.

They were gone.

"Ain't that the truth?" They were leaning back to back with me.

"And with your power, Cter-"

"Stop."

"... I'm just saying, Cter..." They grinned, black blood running in droplets from their eyes down their face.

"When push comes to shove, we both know who you really are."

"Heh... That so?" Memories flashed around us.

I could see through Chara's eyes. The look I had on my face every time I impaled them, crushed them and blasted them...

I sighed, staring at the screens of memories surrounding us.

"You can act sad all you want." They tilted their head back, staring up at the endless, blank white sky above us.

"You can pretend that you feel bad, that you never want to go back." They grinned lightly.

""You can sit there and lie, and tell me hurting people isn't in your nature." They disappeared once again as I sat calmly, not showing any reaction to their words.

"But I want you to remember." I looked up from my place sitting on the ground, seeing they were now standing over me.

"I know you well enough to know that's a lie." They said as I stood calmly.

"Because no matter how much you push it down..." The memory screens shifted to the grin I put on each and every time I watched them die.

"No matter how much you lie to others, no matter how much you lie to yourself..." I took a step back as they stepped forward, aiming their knife at me.

"I will always see through it."

"... Unhuh." I placed my hands in my pockets. "And uh, what, might I ask, leads you to believe this? Other than the creepy snapshots you took." I pointed up at the screens looming over us.

"I've been around for a very long time, Cter. I know the difference between a pacifist and a genocidal. And you are most certainly the latter." They held their hands behind their back, holding their knife there.

I stared at them coldly, a wind beginning to kick up in the flowery plain.

"I can see it in your eye."

"You mean my eyes..?"

"Nope."

I arched a brow in confusion, before that pain struck my left eye again.

I reached up, touching my left eye.

I yelped in pain, pulling my hand away.

My eyes widened, and I saw that fire burning at my hand. That DETERMINED, red fire.

It spread up my arm, my eye continuing to burn at my face.

I yelled in pain, falling to the ground as I was scorched.

The only sound I could hear was their laughter and the crackling of the flames.


I shot up in the bed, gasping for breath.

I touched my left eye.

Just a normal eye...

"Woo wee was that a weird nightmare!" I jumped up out of bed, smiling nervously as I sweated bullets.

"Uh... Cter..?" Frisk got up from their own bed, watching me enter the bathroom, keeping that nervous smile as I looked at my eye in the mirror, opening up my eye lid with my fingers and looking as closely as I could, moving my eye around to see all sides of it.

The only red was the red lines of your average blood-shot eye.

The iris was still it's usual green.

And I wasn't on fire, so that was a plus.

"Cter... Are you alright?" Frisk stood in the doorway, and I looked down, hands on each side of the sink as I sighed.

"Peachy..." I sighed, closing my eyes and shaking my head.

I turned around, seeing Frisk standing there with their arms out to the side, as if they wanted a hug.

"... Uh..?"

"You're getting a hug whether you like it our not."

"Pfft..." I did that about to laugh smile. "Why?"

"Because you're sad and you need it!" They whined, stomping one foot down.

I laughed lightly, shaking my head and rolling my eyes. "Okay, okay. If it'll make you happy."

"It's not supposed to make me happy it's supposed to make you happy!"

"Haha, okay, whatever."

Though I played it off like I didn't need it, I knew I did.

And Frisk noted this as I didn't seem too willing to let go.

"Frisk... Uh, don't take this question the wrong way."

"Um... Okay..?"

"You uh... You aren't going to kill anyone, right?"

"... Cter, we've been over this."

"I just... I need to hear you say it."

They sighed, rolling their eyes.

"I'm not going to kill anyone."

"Promi-"

"Promise."

I smiled lightly.

"... Good..."


"Did you enjoy your sleep? Tra la la~" River Person asked as we went along, and I rolled my eyes.

I just grumbled at them as their boat kicked across the water, stopping at Hotland.

"Tra la la, here you are." River Person stopped in front of Hotland, and Frisk and I stepped off of the boat.

"Good luck, tra la la~" They rowed away, and I sighed, watching them go with narrowed eyes.

We stepped into Alphys' lab, the door opening and closing for us.

The lab was pitch black, the only light coming from the giant screen, which showed us.

... Uh oh.

How could I have forgotten about Alphys?! She's always watching through cameras! She probably saw all the times I...

Well, shet.

The lights flicked on, and Frisk and I looked over to a startled Alphys.

"O-oh my God... They're already here..." She said more to herself than anyone else.

"I haven't had time to shower or change or clean up!" Alphys panicked.

"Um... We can hear you." I said, waving slightly to get her attention.

"U-u-uh... Y-yes, that you can!" She said, sweating nervously.

"Okay, calm down Alphys..." She whispered to herself.

"H-h-hiya!" Alphys greeted. "I-I'm Alphys, Asgore's Royal Scientist!"

"B-but don't worry! I-I'm not one of the 'bad guys'." She used air quotes over the words.

"Actually... Since you two stepped out of the Ruins, I've been um... Observing you..?" Alphys glanced to the side.

"Your fights. Your friendships. Everything!" Alphys said.

Alphys what are you doing don't tell them that! They'll know you saw him use magic!

"A-and, I was originally going to stop you, b-but..." Alphys looked to the side. "Watching someone on a screen really makes you root for them..."

Stop bringing up watching them! She thought, panicked.

"S-so, I've decided to help you instead!" Alphys said with minimal confidence.

"W-with my intelligence, I should be able to guide you two through Hotland no problem!" She smiled.

"I know a way right to Asgore's Castle!" She said, before looking to the side.

"W-well... Actually... There is a little problem..."

I couldn't help but tune Alphys out as my thoughts drifted to what Alphys would do with the information she'd gathered.

Did she still want to help us because she was rooting for us? Or was it because she was afraid of me?

And then there was that nightmare I had. Was I really talking to them, or was that just a freaky dream?

It seemed real enough... Especially the feeling of being burned ali-... Why is there confetti falling on me?

Oh, right, quiz.

"What's the reward for answering correctly?" Mettaton asked.

"More questions!" Frisk answered confidently.

"Correct! Ready for your prize?" Mettaton asked, grabbing another question card.

"What's the Kings full name?" Mettaton asked, and Frisk swatted my hand as I reached for 'Lord Fluffybuns.'

I pouted as they answered correctly, Mettaton grabbing another card.

"What are robots made of?" Mettaton asked.

"Metal and magic!" I answered before Frisk this time.

How Mettaton managed to say his next question in one breath as beyond me, and how Alphys knew the answer was also beyond me.

"How many flies in this jar?"

"52!"

"What monster is this?"

"Mettaton!"

"Would you smooch a ghost?"

Frisk and I glanced at one another, both slamming a fist down on 'Heck yeah'.

"HECK YEAH!" We yelled in unison, making Alphys laugh lightly.

"How many letters are in the name Mettaton nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn?"

We both glanced at Alphys, looking confused.

She signaled a C, so we picked it.

I drifted back to my thoughts as Mettaton asked about Mew Mew Kissy Cutie and Alphys had an outburst.

"Well I'll ask one you'll be sure to have the answer to." Mettaton said.

"Who does Doctor Alphys have a crush on?"

Alphys signaled us not to, but we ignored it.

"Undyne." Frisk said.

"Yep, definitely Undyne." I nodded.

"No question." Frisk agreed.

Alphys had morphed into a tomato by this point.


"Undyne! Are you going to help me with this spaghetti or not?" Papyrus's voice rang from the kitchen.

Undyne stared with wide eyes at the screen of their TV, seeing Frisk and Cter answer the question easily.

"Undyne?"

Undyne picked up the couch that Sans slept on, jarring him awake.

"YEEEEEEESSSSSS!"

"Uh..." Sans held on for dear life as he was shaken around.

"Undyne? What's going on-" Papyrus stopped dead, seeing Sans be thrown around on the couch with wide eyes.

"OH GOD!" Papyrus exclaimed in shock.

"NGGGGAAAAAHHHH!"

"Undyne if you don't stop this you're gonna krill me." Sans said casually, keeping tight hold of the couch.

"If there's anyway to calm you down, let minnow." Sans grinned, hearing Papyrus groan.

"SANS! Are you really doing this now?!" Papyrus asked.

"Sorry Paps, couldn't pass up the opportunaty." Sans had his usual pun face on, Papyrus throwing his hands into the air, walking out of the room and up the stairs.

"C'mon Paps! I know you love my puns!" Sans called after him. "Don't be so koi about it!"

"Doing this alone is a-" Sans slipped on the couch. "Pain in the bass, you know?"

Sans heard the sound of a door slamming, and he laughed.

"Slam all the doors you want, I refuse to be Gillty!"

"I reely can't believe you're still doing this." Sans said, looking down at Undyne.

He heard the sound of a door being kicked open, watching Papyrus stomp down the stairs with a fire extinguisher.

He sprayed Undyne, making her flail and roar.

"Bad Undyne! Put the couch down!" Papyrus told her, and she hissed, setting it down.

"Papyrus, that was brill-iant." Sans grinned. "You're my herr-o."

Papyrus sprayed Sans with the fire extinguisher.

"Bad, bad Sans! No more puns!" Papyrus scolded, Sans being knocked off of the couch.

Papyrus set the fire extinguisher down, staring at the two now on the floor, both covered in white.

"..." Undyne snickered, throwing some into Papyrus's face.

Sans laughed lightly, throwing a hand full of it into Undyne's face.

Papyrus soon joined in, and soon enough they were having a snowball fight inside with uh... Whatever the stuff that comes out of fire extinguishers is.

I uh... I forgot what it's called.

Papyrus sat down on the floor with them, putting an arm around each of them and pulling them in close.

"So... Who's cleaning this up?" Papyrus said, and Sans teleported away immediately.

"Don't look at me, I've gotta write a letter!" Undyne jumped up, running upstairs.

"..." Papyrus sighed.

"Of course..."
