25 chapters? Dang. Better get started.

By the way, how are you guys? I'm tired. I want sleep and food. Let's go.

…(Start)…

Aster and Papyrus decided to catch up for the many years lost between the two. They sat in front of the TV and ate their pasta together. While Aster was a man of science and never had the chance to be the goof that Papyrus was, he allowed himself to laugh to Papyrus's crazy expressions and passion for the tiny things. Just like he was as a child, Papyrus was a puzzle solving genius. It didn't even take him ten minutes to figure out how the puzzle worked again. Aster was amazed as always. He knew Papyrus had a mind of a hidden genius. The two talked of puzzles and chemical formulas, with occasional cooking skills that Aster was curious about.

Meanwhile, Sans was remaining tranquil. His mind was still fuzzy and clouded from the memories that were shown to him. In fact, he was running through newer memories. He could remember the torturous experiments he had endured, the multiple times he has seen his father and brother torn away from him, and the old feelings and emotions he went through. While he knew he would remember them eventually, Sans only wanted to clear his mind of the nonsense that went on that day.

Frisk felt the same way. While being held by Sans, they could hear Chara speak.

"Frisk, I need to find my body. I don't want to be in you anymore than you do."

Frisk though to themselves and Chara, "Let me relax for once."

"But Frisk!"

"I'm tired!"

Frisk eventually ignored the voice and focused onto Sans's breathing as a distraction. They sighed.

Sans took noticed of the breath and whispered, "you're not asleep, huh?"

Frisk faked snoring which brought a laugh out of Sans.

He simple replied, "looks like you have a resting tired face."

The joke didn't make sense to Frisk but Papyrus groaned loudly to it. Aster simply snorted softly.

Chara spoke in an oddly menacing tone, "That was horrible!"

For a split second, Frisk lost total control over their body. While they didn't care much for the joke, their head was filled with a strange sense of rage. They felt like they couldn't control or trust their body. The feeling was horribly off and sudden. Their arm pulled back and aimed for Sans's jaw.

CLINK!

To Sans, all he felt was a light push. Normally, it wouldn't have mattered to him. Kids like to joke all the time; it was a human thing to punch someone softly while joking. What worried him, however, was the implications of the punch. His health went down by 0.1.

Immediately, Sans jumped off the couch and stared at the child sitting down, staring back at him.

For a split second, he saw red eyes that transformed back to Frisk's normal eyes.

"kid…" Sans gasped as he rubbed the small spot where the child punched him.

There was a moment of awkward silence between the family members. Papyrus and Aster noticed something was wrong and turned around to look at the commotion behind them. Sans was terrified that something was wrong with Frisk. Frisk would never hurt another soul, especially their closest friend. Papyrus was confused on what had just happened and Aster could feel a ball of anxiety enter his gut again, like always.

The moment Frisk fought back for their body after the punch, they were horrified. They had just betrayed their family and caused them pain. How could they forgive them? How could they trust them? They immediately began tearing up, placing their hand on their chest to sign SORRY over and over, and ran from the group to the door to the outside. They swung it open and ran, despite the calls of the skeletons.

Immediately, Frisk began to shiver. Their sweater and shorts are not going to be enough in this weather, but they really didn't care.

They thought to Chara, "What was that!? You weren't going to do that!"
"Frisk, please trust me. I wouldn't have hurt Sans. I don't like hurting monsters. It's just… something took over me. I don't know what. I'm scared, Frisk."

"It doesn't matter. If I did that on the surface, I would be beaten. Here, I'm sure the least they'll do is kick me out. I'm so worthless. Why did you do this, Chara?"

Chara remained silent this time as Frisk continue to run. They took two rights and hoped that they would find somewhere safe. To their dismay, the came across a flowing, freezing river. Was this the same river that Sans was talking about?

For some odd reason, Frisk really wanted to jump. Would there be someone that would want to save Frisk? Then it dawned onto them: everyone wanted to take them away to a King, one who may want to kill them. They had no idea what was in store for them if they got captured, or rather when. Sans and Papyrus couldn't protect them forever. While most monsters have been generally nice, what if they come across one that was mean? Even Sans said he was avoiding another monster earlier.

Now that they think about it, what has happened all the humans that have come down here? Obviously, monsters recognized them as human, so they must've seen one before. In fact, you could almost say that they wanted to avoid Frisk. While Sans and Papyrus were nice to them, they seemed to notice that some monsters would stare at them while they were not looking. Were they really this weird?

It seemed like Frisk could never fit in. They were not a skeleton and were not as funny, quirky, or intelligent like Sans, Papyrus, and Aster. They probably would not be able to gain their trust back and would have to run away again, just like on the surface.

The sporadic, illogical thoughts kept flooding their head.

"kiddo, what's going on?" Sans called out behind them, but it sounded faint, as if Frisk were in a dream that Sans was trying to get them out of.

Does Sans even care for them? Does Papyrus think they are funny? Does Aster trust them?

It didn't seem to matter now. Nothing matter.

Frisk lost DETERMINATION.

"kid. Wake up!"

Sans's voice broke through Frisk's daze. They were being shaken by him.

Frisk's eyes opened up to a new surroundings. They were perched against a tree which stood close to the river. Frisk shivered as they realized that they were drenched in water that was already beginning to freeze. Did they jump in?

They signed towards Sans with shaking hands, "WHAT HAPPENED?"

"YOU JUMPED IN RIVER."

"WHY?"

"I-D-K."

Frisk sighed. "COLD."

Sans nodded and picked up the child and teleported back home as fast as he could. There was no time to waste. When Sans finally made it home, Papyrus immediately opened the door, with a worried Aster looking from behind.

"YOU FOUND THEM!"

"go get them clothes, papyrus. aster, get some towels."

The two ran off to do their respective chores as Sans brought Frisk indoors. He went straight to the kitchen where he used one hand to turn on lukewarm water on the sink. He place the child in the sink and let them heat up.

They still were shaking, but the signed towards Sans, "THANK YOU."

Aster came in with a towel and gave it to Sans.

"What happened, son?"

Sans shook his head, "not now. they need to warm up first."

Aster understood, but didn't leave the kitchen, "Yes. I think they should be warm now. Here let me-"

He walked closer to Frisk to pick them up, but Sans beat him to it. He lifted the child with his hands and used his magic to lift the fluffy towel around the child. He held them close.

Sans held Frisk as he rushed to Papyrus's room and pushed the door open. Sans was greeted with Papyrus close to the door.

"OKAY BROTHER! I FOUND THEM SOME NICE CLOTHES."

"leave the clothes on your bed and let them change in here."

"I SUPPOSE SO!"

"let's hope it's fashionable."

"IT IS, SANS! YOU WOULD BE PROUD OF MY SELECTION!"

The two dropped Frisk and the spare clothes off as they left the room to give Frisk privacy. Most notably was Sans's final words before shutting the door, "we'll leave you abone, kid."

Frisk looked at the onesie and trousers(?) that Papyrus left for them. They slipped off their wet clothes that clung to their skin heavily and quickly dried themselves with the towel and pulled on the trousers, not wanting to remain naked for long. They shivered and chattered their teeth as the cold that surrounded them still stayed persistent. Frisk unzipped the midnight black onesie and crawled into it, letting the warm fur brush against their skin and devouring them in heat. They zipped the onesie up to their neck before realizing there was a hood. As they pulled their hood over, they were surprised to see it cover their entire face, but two eye holes that let them see out.

They looked around the room and saw a tall mirror that they could use. When they stepped in front of it, they could understand why Papyrus picked it. The black onesie had white bones painted or sewn onto it to make it look like a skeleton. The smiling face stared back at Frisk as if it was Frisk themself.

Frisk smiled underneath the onesie as they walked out of Papyrus's room and down the stairs. As they walked, they noticed that Papyrus and Sans were in the kitchen talking and possibly cooking while Aster was sitting on the couch waiting patiently. He stood up at the sight of Frisk and smiled. His eyes lit up, literally.

"My, my, aren't you just a little bag of bones."

Frisk giggled and slowly jogged over to Aster, but hesitated to get close. They still felt uneasy around the older skeleton, but wanted to trust him.

Aster bent down to Frisk, who slightly jumped, and spoke, "Don't be afraid. You don't have to Frisk you safety around me."

Frisk snickered and subconsciously signed, "FUNNY."

Aster responded with "I TAUGHT S-A-N-S JOKES" in which Frisk replied with an elated "YOU KNOW A-S-L TOO?" Aster looked confused and signed, "I DON'T KNOW A-S-L. WE CALL THIS SPEAKING IN HANDS. DO HUMANS SPEAK IN HANDS?" Frisk shrugged and replied with, "HUMANS SPEAK IN HANDS BECAUSE NO HEARING OR SPEAK TO DEAF PEOPLE." Aster rubbed his left crack with this thumb before signing "INTERESTING."

While the two conversed, a pot clanged on the ground in the kitchen and Papyrus was yelling. Apparently, Sans told another bad joke which caused Papyrus to have a fit. Papyrus stormed out of the kitchen with literal fire erupting from his nostril hole (which confused Frisk to the point where they think that this was some sort of setup by someone who was too lazy to give Papyrus a proper description of anger but just told themself that that was ridiculous as Papyrus was just standing right in front of them stomping his foot like he always does when angry). He stomped very loudly and dramatically towards a now rising Aster, who was smart enough to know that Papyrus loved the young human with a passion. Aster stepped aside to let Papyrus look at the young skeleton.

"I DIDN'T KNOW IF IT FIT OR NOT BUT IT DID! YOU LOOK EXACTLY LIKE A SKELETON!"

Frisk pulled back the hood and smiled at Papyrus, who proceeded to lift them in his arms and hold them.

They whispered "I'm going to be like Sansy" before hugging Papyrus back and fake snoring.

Papyrus sighed deeply, "TINY HUMAN, YOU DON'T ALWAYS HAVE TO BE LAZY LIKE SANS."

Frisk smiled, "I can also cook like you, Pa-PIE-rus."

"YES YOU- UGH! HUMAN WHY!"

Frisk giggled and jumped out of Papyrus's arms to run and find Sans.

"I'm off to learn more puns!"

"NO! HUMAN! DON'T LET HIM POISON YOU!" Papyrus cried, but secretly, he could cry tears of happiness that the human was starting to fit into their family by opening up more and allowing the Great Papyrus in their life.

Frisk ran into the kitchen to be greeted with Sans's body. They nearly fell back as they didn't think that Sans would appear so suddenly.

"woah, kiddo. don't trip yourself. that's frisky."

They smiled mischievously, "Aster already used that Sansy. Your jokes are running bone-dry."

Sans looked down at Frisk and responded only with, "that made me weak to my stomach. i literally couldn't muscle that. you really like tickling my ribs, don't ya, my child."

Sans laughed at his own jokes before stopping at the sound of Frisk's whimpers.

In Frisk's head, the moment that Sans called them "my child" set them completely emotional, not only Frisk, but Chara. The two of them were reminded of Toriel's constant "my child" towards them. How could they associate "my child" with anything other than a loving parent who only wanted the best? Sans's "kid" always seemed more of a quirky nickname, but hearing "my child" just filled Frisk with a need to stay within this house. After going through how many years of boneliness (that was a bad one), they could finally feel like they had a family where they not only were loved, but was accepted. They weren't "it" here. They weren't broken. They weren't a boy, a girl, trash, a useless child, an overly shy kid, or someone who wouldn't be missed. They were Frisk.

Frisk felt warm tears fall on their face as Sans began to worry and begin to crouch slightly to wipe their tears, but he didn't get far as Frisk hugged Sans around the neck, clinging onto him as tight as possible.

"Thank you." For some reason, out of nowhere, a thought appeared in Frisk's head which then posed a question, "I promise we'll make sure Semi doesn't hurt you anymore. You have to be scared seeing how his name is scary for you and Aster. I'll make sure he doesn't hurt our family."

"geez kid, you sure are great, you know? you saw right through me, my little skeleton."

…(End)…

I made this long just for you guys… and also for me. (Seriously, this is cute.)

I just realized that my ASL in this fic is not exactly perfect. Sure, some sentences would be considered correct, but I'm noticing that some words may or may not exist within the ASL vocabulary, so I'm sorry if I mess anything up! Feel free to tell me my mistakes.

Also, thank you ThatApolloKid6123 for giving me the idea of the skeleton onesie thingy. I tried my best to up the cute, but I don't know how that went.

Also thanks to the hundreds of Undertale comics that I read and cry to at 2 o'clock at the morning. Thanks for wasting my time for the past two months. If you haven't guessed it yet, the reason why the fic is so cheesy is that it's 3 in the morning. Ha…ha… sleepy time.
