The room was dark, cramped, and cold. Several scientific and strange inventions filled the room. A strange device began to blink rapidly. A short skeleton rushed over to it. A piece of paper spewed out of a slit in the machine.

"these results can't be right," Sans muttered. "frisk stopped with the timeline shenanigans. flowey's not here anymore either." Sans sighed. "whatever. i'll worry about it in the morning. maybe the machine is just acting weird."

He rubbed his eye socket and teleported out of the room.

"Sans! You've been in your room ever since the ceiling lady left... and after you talked to the children about school," Papyrus exclaimed. "Are you taking a nap," he demanded.

Sans opened his door, rubbing his eye socket. "huh?"

Papyrus sighed. "Of course you were. Why are you so lazy," Papyrus demanded.

Sans shook away the sleepy feeling. "heh. you got me. i'm just a bit of a lazybone." He yawned. "oh. is there something you wanted?"

Papyrus nodded. "Yeah! I just wanted to apologise for ruining your date."

"what? no pap. you didn't ruin it."

"You left the restaurant Sans," Papyrus muttered.

Sans sighed. "look, me and tori just didn't feel comfortable there, so i took her somewhere else."

Papyrus grimaced. "Please don't tell me that it was Grillbys."

"nah. i didn't take her to grillbys. that place's closed anyway."

Papyrus breathed a sigh of relief.

Sans yawned.

"Sans, did you get any sleep last night?"

Sans shook his head. "nah. i couldn't go to sleep."

"Was it Chara?"

Sans paused for a moment.

Papyrus sighed. "We're all kind of scared of her, but that doesn't mean that anyone needs to lose sleep over it."

Sans chuckled.

"And don't think I don't know that you've gone through quite a lot!" Papyrus frowned. "You don't have to worry though. We all know what to expect, or at least I do."

Sans smiled. "okay. you got me. i've been worried about everybody. i just... don't wanna lose you guys again."

"Well then, I'll let you slack off this time! Consider it a great gift from your great brother!" Papyrus was grinning. His gaze softened. "So please get some sleep."

"thanks papyrus. it really means a lot to me." Sans yawned and closed the door. He heard footsteps retreat from the door. Sans stretched. "although... with that anomaly appearing on my report, who knows if i can sleep well?" He climbed into his bed and shut his eye sockets.

Papyrus ran down the stairs and into the main room. Undyne, Alphys, Frisk, Chara, and Asriel were watching anime once again. Toriel was once again reading, but she made sure to glance at the group gathered on the couch every so often. Papyrus' footsteps pounded against the ground, causing everyone's head to turn towards him.

"So did you find out why Sans has been in his room," Toriel asked.

Papyrus nodded. "Sans is a little tired right now," he explained. "He didn't sleep well last night."

"Was he worried that I'd kill him in his sleep or something," Chara asked.

"I don't think so. I think he was worried about everyone else though," Papyrus said.

"Fuhuhuhu! That punk's worried about us," Undyne asked. She stood up. There was a small whimper of pain. "They've got me to protect everyone! Why would they be scared."

"Uh... Undyne... y-you're k-kinda standing on my t-tail," Alphys stuttered.

Undyne quickly moved. "Sorry Alphys." Undyne posed in her new spot. "I will make sure that skeleton gets the BEST sleep he's EVER had!" She quickly ran upstairs.

"W-Wait," Papyrus exclaimed. "Undyne!"

Everyone ran after Undyne.

Undyne stood at Sans' door. She frantically turned the knob. "Why would Sans have his door locked," she demanded.

"F-For privacy," Alphys suggested.

"My brother always locks his door." Papyrus looked to the side. "I haven't gotten around to making a spare key for this door yet." Papyrus grinned. "So it looks like we're locked out!"

"Well I think that I'll make my own key," Undyne screamed. The door began to emit a blue light.

"Undyne no," Papyrus exclaimed, but it was too late. She punched a hole into the door and reached for the doorknob on the other side. Undyne unlocked the door and opened it.

"Fuhuhuhu," she exclaimed. Undyne was wrapped in a blue glow. "Huh?"

"undyne... can you leave? i'm trying to sleep," Sans muttered. He lazily flung his arm towards the now broken door. She flew backwards,

Papyrus breathed a sigh of relief.

"papyrus, please try to keep people out of my room,"Sans muttered.

"Uh... your door is kind of broken now," Papyrus informed.

Sans groaned. He grabbed his pillow.

"Where are you going Sans?"

"i'm gonna get some sleep." He sleepily walked downstairs and collapsed on the couch. The group followed him. They groaned when they discovered the skeleton asleep on the couch.

"Come on! We were using the TV," Undnye exclaimed. Undyne picked up the sleeping skeleton and lifted him above her head. "You're gonna sleep in an ACTUAL bed, not on the couch!"

"i just wanna nap," Sans muttered with his eyes still closed.

"And thanks to me, you're gonna have the MOST RESTFUL NAP EVER," Undyne shouted. She ran up the stairs, pounding the ground as she ran.

Toriel sighed. "Something tells me that Sans isn't going to be able to nap."

"It's his fault for being so scared." Chara shrugged. "I mean, would I really kill him in his sleep."

Frisk nodded. "That's exactly what you would do."

There was a loud thud coming from upstairs.

Papyrus ran upstairs. Undyne had forcedly opened a spare room.

"Fuhuhuhu," she laughed. "He's asleep! I wore him out from all the running I did!"

Sans was indeed asleep. He was muttering unintelligible sounds as he napped.

"Is he talking in his sleep," Undyne asked.

Papyrus nodded. "He does that sometimes."

Undyne grinned. "Maybe he'll spill his secrets to us!"

"Uh… I don't think that he'll do that. He sorta just mumbles words," Papyrus explained.

Undyne frowned. "Oh." She made a small smile. "That won't stop me from listening in," she exclaimed.

Papyrus began to try and push Undyne out of the room. "Undyne! We shouldn't listen into his words!"

"If he doesn't say anything of note, then why can't I listen in?" Undnye smirked. "He does say things that I shouldn't know, I'm assuming. Maybe it also has to do with that weird kid we allowed into our house."

Papyrus froze.

"Aha! I gotcha!"

Sans rolled over on his side. He opened his mouth, as if to say something. Undyne grinned as Papyrus winced.

"put it on my tab" Sans muttered. He rolled back over. "i'll pay it."

Undyne frowned. "Really? You've got me all excited to learn some Sans secrets and THAT'S what it is?"

"I thought you paid your tab before you left," Papyrus said. He squinted at Sans. "How large was that tab anyway?"

Undyne sighed. "Whatever! You guys are boring!" She stormed out of the room. Papyrus let out a sigh of relief and followed. He shut the door behind him.

"what is the anomaly?"

So here's a chapter to begin to build things! Yay! Here's where we learn that Sans is STILL keeping secrets from Papyrus. Obviously, AU chapters' gonna come up soon, but what is it? (Please don't answer this one...)

Also, people have been asking if I am going to do what I did for the last chapter again. The answer, maybe. I'll keep some questions in mind, but please be aware that this is not normally an asking kind of thing. If you've got questions, that's fine, but please don't ask every chapter I upload. Nobody's done this, but this is for the future cause I know this can escalate rather quickly.

Anyway, I do hope you liked this! Bye guys!
