A bigger problem comes from a smaller person
"Uhhh...Gaster...? The hell are you doing??" Gaster was sitting slouched over his desk combining chemicals. He turned around at her and took his safety goggles off.
"Ah Frisk! Well...I am not sure about the properties of this experiment yet...that's what i wanted to test. But as far as I can tell...it seems to rewind something's age on a cellular level for a short amount of time depending on the quantity administrated." Frisk lit up like a light bulb.
"OH! I WANNA TRY!!" Gaster raised a bone-brow.
"On what?" Frisk took out a butterfly in a jar.
"This is why I came here! I caught you a butterfly but I couldn't find a caterpillar like you asked....so I guess you could make your own." Gaster lit up.
"Magnificent work Frisk! The circumstances are perfect!! We can turn it into a caterpillar and then use it for my other project." Frisk put on her goggles and started walking towards the older skeleton. She tippy toed and looked at the desk he was working on. They quickly took a drop of the chemical and put it on the butterfly in Frisk's jar. They shrunk as well as with their wings. The two watched in awe as the butterfly turned into a caterpillar.
"This...is...GREAT!!" Frisk said as she picked up the caterpillar. Frisk looked at it in awe as Gaster looked at the liquid in the sun. It had an interesting hue to it. That's when Alphys entered. Gaster, in his thought, got scared when Alphys slammed the door open. Frisk looked at Frisk, startled as well, but Gaster dropped the container for the liquid which shattered in Frisk's head, spilling all over her. She rubbed her head but it was already too late as she started decreasing in age. Gaster stared with blank sockets at the baby on the floor.
"Shit..." He said. Alphys brought her arms to her mouth.
"O-OH MY GOD!! I-I AM S-SO SORRY!! I-IS S-SHE O-OK??" Frisk, looking around confused and seeing the unfamiliar environment, started crying. Gaster and Alphys both winced. The man scooped her up and started rocking her.
"She will be fine...It's temporary but...with that amount..? I don't think she will be back to her older self for around two days..." Alphys bowed down.
"I-IT'S ALL M-MY FAULT! I-I AM S-SO SORRY!!" Frisk finally stopped crying. Her clothes were hanging very loosely around her. Gaster sighed.
"It's my fault Alphys...please excuse me i need to deal with this..." Alphys nodded.
"Y-Yes G-Gaster..D-Do you need help..?" Gaster shook his head. He chuckled.
"I have been a single dad almost the whole time i've had my sons. I think i can manage another kid." Alphys sighed in relief.
"I-I am s-so sorry.." Gaster smiled.
"Don't worry yourself so much...You could however tell Frisk's friends and teachers about this...complication." Little Frisk babbled something and poked Gaster in his nasal cavity. That made him flinch a little but he chuckled, which made Baby Frisk giggle.
"Not so different from old you, huh?" Frisk blew a raspberry at him and both the skeleton and the lizard laughed.
"S-she's so tiny and cuteeee~!!" Alphys said looking at her. It was true she had big honey yellow eyes, freckles and her hair was small and kind of messy. She wiggled her little feet and hands around. Gaster chuckled again.
"Maybe this won't be so bad."
"THAT...is frisk..? like...frisk? my girlfriend and best friend...and she's a baby." Sans said, staring with blank eyes at the small Frisk sitting on his couch. Papyrus beamed.
"I FINALLY GET TO BE THE BIG BROTHER!!" Papyrus said with stars in his eyes. Frisk watched with twinkling eyes the shapes in Papyrus eyes. She threw her hands up and babbled in excitement. Papyrus beamed even more, blushing a light orange.
"SHE'S SO TINY AND CUTE!! NYEH HEH HEH!!" Gaster laughed.
"Don't worry, Sans. She will be back to normal in two days. The chemical runs off at some point." Sans sighed in relief.
"oh thank god...but now that you mention it...she really is cute!" Sans said smirking as he looks at tiny Frisk. He kneels down to her level and she tilts her head confused.
"heya there baby bones~" He says. Frisk immediately resonated with the voice and she put her tiny hands on his cheek-bones. Sans chuckled. She was a small cheerful bean. Sans then remembered the way she would act at night after her nightmares. What could have those parents done to this sweet loving child so she would end up that way? He didn't want to know...
"NYEH HEH HEH! CAN WE TAKE TURNS IN TAKING CARE OF HER??" Papyrus asks excited. Sans smirks as he pulls out his phone and takes pictures.
"i call dibs on the first turn!" Sans says. Gaster frowns.
"I will actually take her, she needs a change of clothes, some dippers and some food." Sans scoffed and crossed his arms in annoyance. He wanted to spend time with baby Frisk...Not fair.
"NYEH HEH HEH!! I WANT TO HELP!" Gaster sighed.
"Alright Papyrus...come with me." The younger skeleton followed the father as he scooped up the little baby. She babbled something again and Sans scoffed again and pulled out his DS. Might as well play something while he waits. Upstairs however. Papyrus was having a hard time understanding something.
"WHY DID YOU KEEP ALL OF THESE..?" Gaster shrugged.
"I will be honest..? I don't know." Papyrus shrugged as well but then Gaster gave him Frisk. He stiffened and froze. He's never been a big brother before.
"HELLO TINY BABY FRISK!" Frisk looked at him for a second then giggled. She was one cheerful baby. The fluff on her head started curling as the humidity wasn't there anymore. Papyrus gasped.
"YOU HAVE CURLY HAIR TINY HUMAN FRISK!! NYEH HEH HEH!! DO NOT WORRY, ME AND FATHER WILL DRESS YOU UP IN NO TIME!!" Gaster chuckled as he pulled out Papyrus old pj's and some dippers.
"Here we go then." After a lot of tries to get stubborn little Frisk to cooperate they finally managed to get her in both. Papyrus came down first with tiny Frisk in his arms and sighed as he let himself and her drop on the couch. However, the tiny skeleton almost dropped Frisk. Sans was fast to catch her with his magic. Frisk looked at her soul with curious eyes as it was a blue heart. She tried to poke it. She shuddered. Sans laughed.
"don't poke that you dummy.." He wanted to grab her but another set of magic enveloped her and she got pulled to the kitchen. She landed in Gaster's arms.
"She needs to be fed." Sans frowned and crossed his arms again, letting his leg bounce in annoyance. He almost had her. Frisk however have Gaster one hell of a bad time as apparently she HATED milk. And that's an understatement. Thank god she was old enough to eat baby food or else...Gaster frowned while he tried again to give her the bottle. She started crying. Gaster started rocking her. She calmed down and immediately fell asleep.
"Interesting...i've never seen a baby refuse milk..." Sans shrugged.
"she did say she used to be lactose intolerant when she was smaller and that's why we get her low fat." Gaster hummed in agreement. Sans was about to take Frisk when Papyrus came in and scooped her. Sans stared in disbelief with empty sockets.
"NYEH HEH HEH!! I SHALL PLAY WITH THE TINY HUMAN." Frisk immediately woke up, but instead of crying just looked confused at Papyrus. She babbled something then blew a raspberry. Papyrus scrunched his face up in disgust as spit went on his face.
"HUMANS HAVE SO MUCH DIFFERENT LIQUIDS...IT'S INTRIGUING BUT DISGUSTING." Sans wanted to say it was actually his turn but Papyrus seemed so happy to finally be the bigger brother, he couldn't possibly break him like that. He sighed and slumped on the couch. Papyrus set Frisk on the floor and they were playing with some huge cubes, almost Lego but safe for babies type of thing, and Frisk was frowning at Papyrus who was building with different colors and uncoordinated. She babbled in protest and with one swift move took his whole tower down. She crawled towards his pieces and started rearranging them. Gaster moved his glasses down to watch better what was happening and Sans stared in disbelief. Papyrus beamed.
"SHE IS TRYING TO TEACH ME!! NYEH HEH HEH!! SHE ALREADY LEARNED SO FAST! I AM A GREAT BIG BROTHER!!" Papyrus kept playing with Frisk. Frisk however seemed a bit smarter than they first thought. She would sometimes try to tell Papyrus stuff. At one point Papyrus got bored.
"OK FRISK...SAY PAPYRUS!" Frisk stared at him and tilted her head. Gaster chuckled. Sans took a few pictures. She was adorable.
"You want her to say your name..?" He nodded.
"PAH-PAY-RUS!" Frisk frowned with determination.
"Pah...pah..." She tried to say. Sans snorted.
"BROTHER!! WHY DON'T YOU TRY TO TEACH HER SOMETHING??"Sans snorted and leaned back.
"i could try to teach her how to pun."
"P-..Pun!" Frisk said throwing her hands up. All three skeleton's sockets went blank. Sans and Gaster started laughing as Papyrus turned towards Sans.
"LOOK WHAT YOU DID!! NYO HO HO...AT THIS RYTHME SHE WILL NEVER SAY PAPYRUS..."
"Paps!" Everyone looked at Frisk. She beamed and was clapping her hands. Papyrus beamed
"YES!! THAT'S RIGHT FRISK!! NYEH HEH HEH!!" Sans frowned and knelt down. He felt jealous. It was stupid but...he didn't get any time with her and she said PAPYRUS nickname.
"hey baby-bones. say sans." He said. Frisk tilted her head and smiled.
"sasy!!" His sockets went blank.
"close enough i guess." She put her hands on his cheek bones and and gave him a peck. He smiled. His soul fluttered in his chest. He was about to pick her up when Gaster scooped her up. His sockets went blank again as he froze, left with nothing in front of him. Papyrus patted his skull.
"THIS IS MARVELOUS! SHE IS DEVELOPING FASTER THAN OTHER HUMAN KIDS!!" Frisk tilted her head as she was held up.
"bleah?" She asked. Gaster chuckled and cradled her.
"I am taking her with me for tests!!" Sans frowned.
"hold up old man, what the hell do you mean?! she's still too young!!" Sans said, frowning.
"It's just tests as in colors and stuff like that...don't worry your skull about it. Here we go!" Sans frowned.
"WAIT! she still has a weak stomach don't telepo-...rt..." His dad was already gone. Sans crossed his arms. Papyrus looked at him and smiled.
"I AM SURE YOU WILL GET YOUR TURN!!" Sans sighed and pulled out his DS again.
"i know, paps...i know.."
He never got his turn. Either Paps or Gaster would steal her from him. It was starting to be very...VERY annoying. He tried after lunch to play with her but Papyrus was already really in the role of a big brother and he tried to put her to sleep. Thank god Frisk was patient even as a baby. She just fell asleep out of boredom. Gaster wasn't lying about those tests, however he noticed something. Frisk was also trying to get to him. He caught her trying to crawl to the couch while she was playing with Papyrus or reaching for him at the lunch and dinner table. Sometimes she would even try to get away from Gaster. That made him feel a tiny bit better about himself. The first night with Frisk however was chaos. She would cry once every few hours. Papyrus had no problem sleeping but him and Gaster had one hell of a bad time.
The next day was filled with more failed attempts. Sans kept trying and trying bout either Papyrus and Gaster would take his chance. However at one point Frisk was the one who got mad. She started crying in rage. Sans was left dumbfound as she kept crying more and more. Gaster and Papyrus were trying to calm her down only to find out they were hopeless.
"FATHER, SHE JUST WON'T STOP CRYING!!" Sans rolled his eye-lights and came into the kitchen and picked her up. She immediately stopped and hugged the skeleton. He smirked. Gaster and Papyrus both frowned at the skeleton. He smirked sheepishly.
"guess she wants me huh?" His smug look only grew as he noticed both his father and brother were jealous.
"heh, heya there baby bones~" Frisk threw her hands up and babbled happily. He ran his phalanges gently through her little fluff of hair. She giggled. Papyrus sighed.
"GUESS SOULS SPEAK FOR THEMSELVES. EVEN AS A BABY SHE STILL FEEL A CONNECTION WITH YOU." Gaster frowned.
"That's enough, give her here. She's calm now." Sans put her down on the couch and crossed his arms.
"hahaha....no. it's my turn, ok? i barely got any time with her...and when i was about to you two would steal her." The three skeletons kept fighting. Frisk looked sadly at the three as tears swelled up in her eyes. She was used to her parents fighting because of her...she knew not to be a bother since and early age. The instincts that have been written by her parents in her kicked in. She left the room so she wouldn't cause more trouble. As the skeletons fought they didn't notice one thing. Frisk was gone.
"LET'S SEE WHO SHE CHOOSES!! FRISK--..." Papyrus froze as he noticed she was gone. Sans and Gaster turned around only to notice what happened. They lost Frisk.
"how in the world--" Gaster palled, if that is even possible for a skeleton, as he saw she was gone.
"Frisk...?" No response. Gaster face-palmed and inhaled.
"...fuck...ok...we just lost Frisk..."
"maybe if you guys would have let me stay with her!!"
"I...I'm sorry.....but...we need to search every dammed corner of this place ok?!" Gaster said panicked. The two brothers nodded at their father and they all left the living room.
"FRISK! FRISKKKK?? WE'RE SORRY FOR MAKING YOU SAD! PLEASE COME OUT!!" Papyrus said as he was searching under the beds. It was getting late and they will soon need to sleep. He ran into his brother who looked really panicked.
"HVE YOU FOUND ANYTHING BROTHER??" Sans sighed.
"i kinda hoped you did...shit- i...i shouldn't have said no...i...i was selfish and...fuck- we lost her now.." Papyrus put a reassuring hand on his brothers arm. Sans looked at him.
"DO NOT FRET BROTHER...IT'S ALL OF OUR FAULTS AND...WE WILL FIND HER! I PROMISE!" Sans chuckled.
"when did you twerp get so smart...?" He beamed.
"THAT IS BEACUSE BEING A BIG BROTHER GIVES YOU A NEW MINDSET??" Sans chuckled.
"hahahah!....no." He said. Papyrus frowned and he patted his skull.
"let's go find her, ok?" Papyrus took on a determined look.
Sans was surprised when he tried to feel her soul and found out she knows how to camouflage herself. She conceals herself from such a young age...That's disturbing. He frowned and started thinking. Where could she possibly hide...? That's when he remembered something. Something Frisk told him.
"I'm not a huge fan of hide and seek. Believe me when I say I played it enough with my parents for survival in that hell of a house. But I do remember I hid A LOT in the closet when I was younger. My parents were too dumb to notice anything. As long as I was out of their sight? they didn't care anymore."
"paps...did you check the closets??" Papyrus shook his head.
"I DIDN'T.." Sans smirked. They avoided the exact place she was in. They went to her room and opened the wardrobe to find, to no ones surprise, a sleeping Frisk. Sans and Papyrus sighed in relief.
"OH THANK GOD SHE IS ALRIGHT...DRESS HER UP IN HER OLD CLOTHES AND WE CAN ALL GO TO SLEEP!" Sans nodded as Papyrus left the room happy to have found the little girl. He changed her and set her on the bed, but instead of leaving, laid next to her.
"hope you'll be back in the morning..." He let himself fall asleep as well.
He woke up first. His eyes were still close and he prayed that when he will open his sockets he will see normal Frisk. When he opened them, he did. She was sleeping peacefully next to him, her chest slowly going up and down as she was breathing. Sans jumped on her and pulled her in a hug. Frisk woke up from the sudden hug and they both fell out of bed.
"WHAT THE HELL SILLY-BONES??" Frisk said, frowning. Sans just chuckled as he tightened his hug.
"OH THANK GOD YOU'RE NOT A BABY ANYMORE!!" Frisk stiffened.
"A baby...? THAT'S RIGHT! GASTER DROPPED HIS CHEMICAL ON ME! Oh my god i was a baby...Wait...WHAT DAY IS TODAY??" Sans smirked.
"it's monday." Frisk whined.
"NOOOO! I missed the whole damn weekend...uughhhhh...fuck that experiment.." Sans gave her a smug look.
"oh come on baby bones~ i have pictures~" Frisk flushed.
"WHAT?!" He started laughing as she jumped on him and they started playfully wrestling. She won and was now on top of Sans back. He groaned.
"get off you pig.." Frisk snorted.
"oink oink. nopeeee. now....what happened when i was a baby?" Sans shrugged.
"we just found out you are super smart... a-and your soul resonates with m-mine." Frisk looked at the little blushing Sans under her and gave him a kiss on the cheek-bone smiling satisfied.
"Told you we were soulmates~! The power of traumatic experiences!! WHOOO!!" Frisk said throwing her hands up as Sans flushed bright blue and took the pillow and started using it to get her off. She fell off of him and started laughing as she got hit by the fluffy pillow.
"what the hell?! don't say it like it's nothing you dummy!!" They both laughed as they kept fighting with pillows, but Frisk technically wasn't lying as even in that moment, their souls were fluttering in their chests at the sight of each other.
