The elevator practically crashed into the basement. Again. Sans flew back and banged his head against the wall. Again. They needed to put some frikkin seatbelts in here before he cracked his head open for real.

Sans groaned and rubbed his head as the elevator doors slid open. He hoisted himself off the floor, wobbling his way into the cold, dark, borderline slimey lab. This place never failed to give him the creeps. Even though he spent a good chunk of his life down here, for some reason he almost always shivered upon going down the hallways. There were times that you couldn't even see the end of the hallways. They needed to get some goddamn lights in this place. But for some reason Gaster always liked it this dark. Said it always "Helped him think better" or something like that.

He opened the door to the study room, where he found Gaster hunched over his desk, furiously scribbling on paper.

"... Gaster? What's up?" He asked, looking around the annoyingly dark room. It was a miracle he could write anything down in here. Gaster didn't respond. He squinted aggressively at his writing, his glasses slightly crooked from forgetting to straighten them.

"Uh… Whatcha call me here for?" Sans asked as he walked the rest of the way through the door. Gaster finished his last number on the paper, looking it over it again and again to make sure everything was correct.

"Sans… I think I did it." He whispered. "I think I found a way."

"Uh… Okay… I'm not one to criticize a prank, but I seriously just walked all the way over here from Snowden and Grillbyz was-"

"I'm serious, Sans." He interrupted, handing him the paper.

"Uh… Are you sure? I mean… You've been working on this since before… Well… Me." Sans glance over the paper, scanning through the equations. "I mean, there's no way-"

Sans stopped in his tracks, sockets widening as he read more closely.

"Holy… Holy shit. Are you serious?! Are you… No way. No fucking way."

"Sans… I've done it." He said, putting a hand to his head and smiling. "I've done it. I can't believe it. It's been so long..."

"Hey, Hotshot. I helped with at least a third of it. Gimme at least a little credit."

"Of course, forgive me. We did it, Sans. We did it."

"Nah, I was just fuckin with ya. I did next to nothin." Sans looked over the paper once more, this time, it must have fully hit him. His hand started shaking, blue dripping from his sockets, almost dripping onto the paper.

"Have… Have you told Alphys? Asgore?" He sniffed, a half grin forming on his face.

"Not yet. I wanted to let you know first." Gaster said proudly.

"... God… We did it. I can't believe this." Sans whispered, wiping his face and handing the paper back to him. "Can I… Can I tell Papy-"

"Wait a little while. We still need to test to see if it works." Gaster said, resting a hand on Sans's shoulder. "But in the meantime, think about what we've accomplished, Sans. This… This will change everything. This will change Monstrosity… This will change Humanity… This… This will change the world Sans."

"I… I know, Gasty. I know… I'm… I'm just so happy knowing that all of that work… Every second of it… It wasn't all for nothing. I just…" Sans put his face in his hands, his shoulders shaking. "We've been working on this for as long as I can remember… God, we did it. We finally did it."

Suddenly, Gaster kneeled down and embraced Sans. He made muffled sound of surprise against his lab coat in surprise. He eventually returned the hug, feeling warmth down to his marrow.

"Sans, we could make it so that Monsters and Humans can be at peace again... We can make it so that the war never happened."

"I know… I know Dad."


"SANS! YOU'RE ACTING MUCH HAPPIER THAN USUAL TODAY! THAT'S FANTASTIC!"

Sans heard Papyrus shout at from the other room as he hummed while he stirred an egg mixture in a bowl.

"I guess so, bro. I guess so." He said, shaking salt and pepper into the mix.

"WHY, YOU'RE COOKING AND EVERYTHING! INCREDIBLE! YOU MUST HAVE FIGURED OUT WHAT I WAS GOING TO ANNOUNCE TO YOU AND GASTER TODAY!"

Sans grinned, putting down the whisk and turning away from the quiche he was making.

"Yeah? What's that, bro?" Sans asked, finding Papyrus standing proudly before him.

"FAKING THAT YOU DON'T KNOW WHAT I'M TALKING ABOUT SO THAT YOU'LL MAKE ME FEEL BETTER, EH? FEAR NOT! FOR I AM NOT OFFENDED BY YOUR ACCIDENTAL REALIZATION! IN FACT, JUST TO PROVE HOW NOT OFFENDED I AM, I SHALL PLAY ALONG AND TELL YOU ANYWAY!"

Papyrus cleared his throat and stood tall, towering over Sans.

"I, THE GREAT PAPYRUS, HAVE DECIDED THAT I WANT TO JOIN THE ROYAL GUARD! I WILL PROTECT THE ENTIRE UNDERGROUND WITH MY SKILL AND MIGHT! I WILL BECOME KNOWN AS THE MOST BRAVEST, THE MOST MIGHTY, AND THE MOST CHARISMATIC KNIGHT IN THE ENTIRE UNDERGROUND! NO, THE WHOLE WORLD I SAY!"

Sans's smile shrunk. He almost let it be smacked off of his face, but he stopped himself just in time.

"HMM? WHAT'S WRONG, BROTHER? YOU SEEM UPSET ABOUT SOMETHING."

Sans shook his head, snapping himself out of it.

"What? 'Course not, dude. I'm just-"

IN AWE, ARE YOU? SURPRISED THAT I WOULD PUT MY GREATNESS ON THE LINE? ONCE AGAIN, FEAR NOT! I WILL SURVIVE ANYTHING THAT ANYONE THROWS AT ME! I WILL SIMPLY LOOK AT ANYONE THAT GETS IN MY WAY, AND THEY WILL TREMBLE IN FEAR BEFORE ME! THEY WILL FORGET THAT THEY WERE SUPPOSED TO FIGHT ME, AND WILL RUN COWERING IN FEAR, GRANTING ME VICTORIOUS!"

Papyrus, kneeled down next to Sans, putting an arm over his bended knee.

"DO NOT WORRY, BROTHER! FOR NO HARM SHALL COME TO ME! I ASSURE YOU!"

Sans forced himself to smile, not making eye contact.

"Thanks, Papyrus. I feel a lot better knowing that. Now, I gotta get back to makin that… Uh… Thing. 'Kay? You work on that."

"BUT OF COURSE!" Papyrus exclaimed. "I SHALL BE IN CONTACT WITH THE CAPTAIN, UNDYNE, AS SOON AS POSSIBLE!"

"Alright, but not before dinner, okay? I'm workin real hard on this and I don't want it all to go to waste." Sans said, going back into the kitchen.

"UGH, FINE. BUT MAKE IT QUICK! I NEED TO GO PRACTICE MY ACCEPTANCE SPEECH!" He said, dashing up the stairs and into his room.

Sans let his face drop.

He didn't have the heart to tell him that the Royal Guard would be obsolete soon.
