The Great... Sans? (Underswap! Sans X Reader)

Let's Clear up some Things

You fell to the ground after everything had stopped melting, curling into a ball and sobbing your heart out.

You knew Papyrus had managed to teleport you two to safety, but that didn't matter as long as it meant that Sans, no, that MONSTER controlling Sans was still out and about.

After you had calmed yourself down you sat up, wiping what you tears you could away with your soaked hoodie sweater. Looking around you realized you were in the waterfall, with a bench not to far away which Papyrus was sitting on. Underneath it was a quich, but you decided not to take it. You weren't ready for that responsibility.

Sitting next to Papyrus, who was sobbing into his hands quietly, you leaned into him and wrapped your arms around his torso and giving him a heartfelt hug full of sorrow and pity. The poor man, you couldnt even begin to imagine what he is going through.

"Papyrus. I know how this looks right now. But I promise you, with every fiber of my being, I will save Sans from that monster."

He chuckles darkly and removes his hands. Tears are still streaming down his face as he gives me a cold, unforgiving smile.

"I EXPECTED YOU WOULD KNOW HOW TO HANDLE THIS."

You looked at him in confusion and removed your hands from the hug.

"What do you mean?"

He glares at you, his smile faltering a little, "DONT ACT LIKE YOU DONT KNOW."

His smile completely dissapears and is replaced with a ugly scowl.

"DONT YOU DARE STARE AT ME LIKE YOU DONT REMEMBER!"

Tears pool out his sockets as he glares at you, and he takes angry breaths as if he's restraining himself.

"Papyrus, I dont understand-"

"OH, YOU DONT UNDERSTAND. THEN LET ME CLEAR IT UP FOR YOU."

He stands up off the bench and beguns to pace, breathing harder as he tries to control his temper.

"THIS ISNT THE FIRST TIMELINE WHERE SOMETHING HORRIFIC HAPPENED TO SANS, BUT YOU WOULD KNOW THAT, WOULDN'T YOU? BECAUSE EVERY TIME IT WAS AT YOUR HANDS."

You stare at Papyrus in horror. You had hurt Sans? But why?

"Why?"

He forces a laugh, "YOU TELL ME."

You place your hands to your forehead, a heavy feeling in your chest.

"What are timelines?"

Papyrus shakes his head, but answers anyway.

"TIMELINES ARE DIFFERENT REALITIES CREATED EVERY TIME YOU RESET."

"Reset?"

"YES, YOU CAN RESET THE WORLD. BUT ONLY UP TO YOUR STARTING POINT, WHEN YOU FELL DOWN."

Processing this information, you stare at your hands, as if you could see this power course through your veins.

"If I can reset the world, and I have done it before, then why can you remember?"

He sighs, "I DONT REMEMBER ALL OF IT, BUT I REMEMBER PARTS, MOSTLY THE IMPORTANT MOMENTS, SUCH AS DEATHS OR BIG BURSTS OF EMOTION I HAD."

You rub your face, take a deep breath, and ask one last question.

"Papyrus... what happened in the previous timelines?"
