I find San's and Papyrus's relationship to be damn heartwarming.

But after seeing what happens in a genocide run, the incredibly real, fierce love Sans has for Papyrus seems to be unveiled for the first time. The ending, well, broke my heart, to be honest. So I decided I'd make a backstory for the duo in the perspective of Sans. *SPOILERS* I found his surprisingly god-like power in the Sans battle really interesting, so this provides some explanation for that, as well.

This chapter is fairly short, but later on they get longer and more in depth.

Anyways, I hope you enjoy. Love you, Sans.

I can recall every memory, from the beginning to the bitter end. It all seems like a dream, now.

Family? Nah. Not gonna go through all that. Family is the ones that stick with you, through and through.

My own blood and bones didn't.

Papyrus did.

And that's history.

He'd leap out of bed like he was launched out of a catapult at the first hint of dawn. He was so excited, so determined, perpetually. I'd fix myself my morning cup of ketchup as he sprinted outside in his makeshift "battle body" and brandishing this tattered, old sword we found in the snow one day, swinging it around as if he were possessed by a five-year-old demon and threatening the heads of the other innocent kids around town.

It was so long ago.

We're skeletons. We age like death. It could be centuries ago, for all we know.

I remember when he finally got his attack down, the "blue attack". He'd been trying ruthlessly for months, prancing out the house in the morning with an incredible amount of energy, as usual, and coming back with the same giddiness as when he left. He'd beg the Royal Guards to help him out, show him some attacks, but they'd usually tell him to piss off. He'd run to the library and grab every book off the shelves if it had the words "puzzle", "attack", or "human" in it. He'd practice constantly, ask whoever passed by to battle. They regarded him as a freak. But even with all that, he wouldn't let up. I kind of admire that about him. That annoying persistence, that never-give-up innocence. He tried tirelessly to the point that it aggravated me every time he came back in the evening, hardly any progress to pay for his work.

I was reading the newspaper, as any teenage skeleton would, sipping my ketchup. It was just like any other day. He was outside, battling a snow poff. The snow poff seemed to be winning.

But suddenly, I heard a scream. My bones were rattled; I thought the snow poff must've attacked him. So I started towards the door, but a few feet away from it, he barreled through, more excited than I'd ever seen him, which is saying something for a guy who seems to be on Red Bull every moment of his life. He was screeching incoherently, something about snow, humans, the royal guard, and a dog.

I just looked. And grinned.

He frantically dragged me outside, presenting me the pile of snow, mildly disturbed from some kind of force.

I didn't really get it, at first. "Papyrus, your snow poff fell over."

"I know that!" He belted out the first words I could understand. "Do you know why it's fallen over?!"

I stared at him uncertainly, shrugged.

"I did it!"

"Whattaya mean?"

He folded his arms over each other, cocked his chin into the air smugly. He was trying to play it cool, as he always was, but his childish excitement was about as evident as the fact that we were skeletons. "Well, Sans, it all payed off, finally! That snow poff has been defeated by me, the great Papyrus, with my infamous blue attack!"

Immediately upon finishing his sentence, he readied his fists, facing me in a somewhat sassy, aggressive stance. "Fight me, Sans! Let me show you how amazing it is!"

"Whatever you say, bro."

Needless to say, I was impressed. Papyrus wasn't the most intimidating person, but his blue attack was special. I'd never see anything like it before.

And I was proud as any brother would be.
