"come on dad, why are you always at the lab?" Sans asked his father.

"yeah, i know. i know." Sans sighed. He lived in Hotland, with his creator, W.D. Gaster. He called Gaster "dad" because that's what he thought of him. After all, for years Gaster took care of him, fed him, and raised him. True, he was occasionally tested on and experimented on, but Sans was actually given a large amount of freedom, and he grew to love his father. After all, he had no one else. Sans was a clever child who loved learning and asking questions. He was very good at seeing people for who they really were. He could tell Gaster wasn't a bad person, even though he did occasionally experiment on him. Sans could always see that Gaster didn't want to do it. Gaster always said, ✂︎✋︎ ☟︎✌︎✞︎☜︎ ❄︎⚐︎ 👎︎⚐︎ ❄︎☟︎✋︎💧︎📬︎ ✋︎🕯︎💣︎ 💧︎⚐︎☼︎☼︎✡︎✂︎ ("I HAVE TO DO THIS, I'M SORRY") Before testing on Sans.

Sans lived in the Lab, but he had his own room. It looked like a normal kid's room, with toys and books and a nice bed. Sans wasn't really allowed to leave the lab, so the only person he ever saw was Gaster. Gaster rather enjoyed having Sans around. Though he originally created Sans to use primarily as an experiment to hopefully bring down the barrier, he did grow attached to the young skeleton. He really did feel bad for experimenting on Sans, so he had an idea. He would no longer cause Sans any pain, and his original plans would barely need to change.

SINCE I HAVE GROWN RATHER ATTACHED TO SANS, I FEEL TO GUILTY EXPERIMENTING AND TESTING ON HIM. NEVERTHELESS, I MUST CONTINUE MY PLANS. THIS PAST YEAR I HAVE BEEN WORKING ON A NEW BEING, USING SIMILAR DESIGNS I USED WHEN CONSTRUCTING SANS, I PLAN TO CHANGE SOME FEATURES ON THIS ONE TO PREVENT ME FROM GETTING ATTACHED. THIS ONE WILL BE STRONGER AS WELL, SO MY EXPERIMENTS WON'T EFFECT HIM AS MUCH.)

Gaster sighed. He didn't feel good about bringing another being to life. The newer model was already a year old. Almost exactly five years younger than Sans. He planned to never tell Sans about his new creation. All he cared about was breaking the barrier. Then maybe, he and Sans could be happy on the surface.

"so... i couldn't help but notice that it's been a whole year since you've tested on me" Sans said to Gaster one day. "does that mean you've found what you're looking for?" Gaster shook his Head. ✂︎☠︎⚐︎📪︎ ✋︎🕯︎✞︎☜︎ ☺︎🕆︎💧︎❄︎ ☞︎⚐︎🕆︎☠︎👎︎ ✌︎ 🕈︎✌︎✡︎ ❄︎⚐︎ 👎︎⚐︎ 💧︎⚐︎ 🕈︎✋︎❄︎☟︎⚐︎🕆︎❄︎ ☟︎🕆︎☼︎❄︎✋︎☠︎☝︎ ✡︎⚐︎🕆︎📬︎✂︎ ("NO, I'VE JUST FOUND A WAY TO DO SO WITHOUT HURTING YOU.") Sans sighed. "oh, that's good." and didn't think much of it.

One day, Gaster had spent an extra long amount of time in the lab. Sans kinda missed him, so he thought he'd go down and check out what was happening. He snuck down to where Gaster usually conducted his experiments, cracked open the door, and found Gaster asleep on top of some of his notes. "ah, he must have just fallen asleep down here." Sans thought to himself. He was about to make his way back to his room when he heard a soft crying. He suddenly felt worried. "is someone else down here?" He thought. He immediately got a worried feeling. "i shouldn't be down here. i'm going to go back. i'll ask him about it later."

The next day, Gaster walked up to Sans's room to say good morning and to eat breakfast with him. Sans decided to pop the question. "hey dad? i couldn't help but hear some soft crying last night. i was just wondering what that was." Gaster looked shocked. Oh no. He couldn't let Sans find out about the other being. Gaster got up. 👎︎⚐︎☠︎🕯︎❄︎ 🕈︎⚐︎☼︎☼︎✡︎ ✌︎👌︎⚐︎🕆︎❄︎ ✋︎❄︎📬︎ ✋︎ 🕈︎✌︎💧︎ ☺︎🕆︎💧︎❄︎ 👍︎⚐︎☠︎👎︎🕆︎👍︎❄︎✋︎☠︎☝︎ 💧︎⚐︎💣︎☜︎ ☜︎✠︎🏱︎☜︎☼︎✋︎💣︎☜︎☠︎❄︎💧︎📬︎ ✋︎🕯︎💣︎ ☝︎⚐︎✋︎☠︎☝︎ ❄︎⚐︎ ☝︎⚐︎ ⚐︎🕆︎❄︎💧︎✋︎👎︎☜︎ ❄︎⚐︎ ☝︎☜︎❄︎ ☞︎☼︎☜︎💧︎☟︎ ✌︎✋︎☼︎📬︎ 👎︎⚐︎☠︎🕯︎❄︎ ☞︎⚐︎☹︎☹︎⚐︎🕈︎ 💣︎☜︎📪︎ 💧︎✌︎☠︎💧︎📬︎ ("D︎O︎N︎'︎T︎ W︎O︎R︎R︎Y︎ A︎B︎O︎U︎T︎ I︎T︎.︎ I︎ W︎A︎S︎ J︎U︎S︎T︎ C︎O︎N︎D︎U︎C︎T︎I︎N︎G︎ S︎O︎M︎E︎ E︎X︎P︎E︎R︎I︎M︎E︎N︎T︎S︎.︎ I︎'︎M︎ G︎O︎I︎N︎G︎ T︎O︎ G︎O︎ O︎U︎T︎S︎I︎D︎E︎ T︎O︎ G︎E︎T︎ F︎R︎E︎S︎H︎ A︎I︎R︎.︎ D︎O︎N︎'︎T︎ F︎O︎L︎L︎O︎W︎ M︎E︎,︎ S︎A︎N︎S︎.︎")

Sans ignored him and stood up. "no. are you keeping something from me?" Gaster clearly looked worried. ✂︎✋︎🕯︎💣︎ ☺︎🕆︎💧︎❄︎ ☝︎⚐︎✋︎☠︎☝︎ ❄︎⚐︎ 👍︎☟︎☜︎👍︎😐︎ ⚐︎☠︎ ❄︎☟︎☜︎ 👍︎⚐︎☼︎☜︎📬︎ 👎︎⚐︎ ☠︎⚐︎❄︎ ☞︎⚐︎☹︎☹︎⚐︎🕈︎ 💣︎☜︎📬︎✂︎ ("I'M JUST GOING TO CHECK ON THE CORE. DO NOT FOLLOW ME.") Gaster had to get out of there and think of a way to cover this up. Sans looked down. "alright, alright. i'll go back to my room."

Gaster left, when Sans quickly turned around. "right after i find out what's going on." He teleported himself to Gaster. He didn't really know what it was like outside of the Lab since he'd never been, but recently he learned how to teleport to a specific person. He needed to find out what was going on. He saw Gaster sitting just outside of what looked like an elevator. He was near a ledge which was right next to the core. One wrong slip and he could easily fall in. He walked in on Gaster thinking to himself. 

"i need to know what's going on. do you have someone else down there. is that why you haven't been testing on me recently?" Sans asked. Gaster looked shocked. ✂︎✋︎ ❄︎⚐︎☹︎👎︎ ✡︎⚐︎🕆︎ ☠︎⚐︎❄︎ ❄︎⚐︎ ☞︎⚐︎☹︎☹︎⚐︎🕈︎ 💣︎☜︎📪︎ 💧︎✌︎☠︎💧︎📬︎✂︎ ("I TOLD YOU NOT TO FOLLOW ME, SANS.") Sans looked annoyed. "come on, what aren't you telling me. i am okay with you keeping me locked away from the world, i don't question most of the things you do, heck, i even let you experiment on me, so why won't you tell me what you're doing?" Sans stepped towards Gaster. Suddenly, the ground started to crumble beneath Sans. 

✂︎💧︎✌︎☠︎💧︎📪︎ 👎︎⚐︎☠︎🕯︎❄︎ 💣︎⚐︎✞︎☜︎✂︎ ("SANS, DON'T MOVE")

Sans continued to step forward. "are you testing on someone else? i don't want that. i'll let you test on me. i don't want someone else to deal with that for me. that's why i was created." The ground continued to break. It was incredibly unstable. 

✂︎💧︎✌︎☠︎💧︎✏︎ 🕈︎✌︎❄︎👍︎☟︎ ⚐︎🕆︎❄︎✏︎✂︎ ("SANS! WATCH OUT!")

The ground below Sans fell away. Sans began to fall, when Gaster pushed him aside. Then almost in slow motion, Gaster fell backwards into his creation, The Core. Sans watched, fear flashing before his eyes. "wait! wait! no!" He called out, watching his father figure fall away. Suddenly, the world started glitching. Sans held his head. "what's happening??"
