Lengthy oneshot because I suck

I don't know how wattpad works

     Papyrus had finally gone over his limit. He had remembered every single reset, though he still didn’t quite trust that they weren’t just broken dreams he randomly recalled. The poor skeleton had countless nightmares of being slaughtered by his human friend, much like Sans’. However, Papyrus had learned to never scream at night. Sans was already stressed enough, and Papy knew that Sans was going through something awful. Although both brothers seemed to have full memory of resets, they both approached them differently.
         Sans kept everything suppressed, yet he expressed his pain slightly. Papyrus, on the other hand, hid it more than Sans. And unfortunately, Sans was too caught up in his own problems to see it. Worse yet, neither knew the full story of what the other was going through. Sans and Frisk had no clue of what was happening to Papyrus, and Papyrus was unaware of Sans and Frisk’s ordeal. Out of the thousands of resets, Sans had never once mentioned anything to Papyrus. Not once. So in that way, Papy thought Sans would brush it off as deja vu or make a bad pun. In the same way, Sans couldn’t bear it to see Papy hurt, even if he was blissfully unaware that secrets hurt Paps more.
     Resets had actually harmed Papyrus more than Sans, as well. Papyrus had been hopeful that Frisk- or Chara, if it was them- would change their ways with each passing reset. Because of that, Papyrus had been let down by every genocide route since the first. Sans had always expected to see them in the judgement hall because he was the type to 
avenge his fallen. But Papyrus was the fallen, and he had a different insight on everything due to that. He had a wish, and that wish was crushed more than a thousand times over. Sans never even considered that the human would change, so it isn’t like he was ever let down like Papyrus was.
             If Sans was wronged, he would’ve wronged the offender right back. Yet if Papyrus was wronged, he would’ve apologized to them! They just weren’t the same. Of course, Pap had a small shred of offense deep within him, but he ignored it. Papyrus was mostly mad at himself, which is why he was there. He was standing in the cold, white Snowdin clearing; the same clearing where he gets killed each time. This was why he had summoned a bone, though nobody was out there. Even if somebody was there, this bone was not for them.
    “It all starts over.. It all starts over..” He assured himself, with quivering words. He’d already written the note that was now tucked into his tattered and red scarf. After what felt like forever, Papyrus slowly raised the bone to his right, next to his neck. Papy sharply inhaled, winced, and struck. A loud, thunderous crack filled the snowing clearing. “Gah!” he shrieked as his legs buckled and he fell to the icy ground. His plan didn’t work; his skull was still attached to his body. Pain shot through the whole of Papyrus as he struggled to check his stats. The health bar read 278 out of 680, which meant he was more than half dead. Papy groaned, weakly raising an arm. A gaster blaster with bright, tangerine-orange eyes appeared above him. With a simple movement of his fingers, the blaster pointed towards him. Papyrus then blasted himself, instantly disintegrating him, but leaving the entirely ground unscathed. Within a quick, painless moment, the Great Papyrus was nothing but a pile of dust inside of a heavily burnt scarf. Odd, the clothes didn’t make it, but the scarf did. Either way, Papyrus was dead now. Not that that was any different than what had happened to him so many times before. 
    Sans made his way down to his post, holding Frisk's hand. He'd thought this was REALLY going to be the last time. It had to be if Frisk didn't want to go through an endless cycle of torture, and Frisk knew that. They made the promise, so this would mark the first pacifist route in lifetimes. Frisk was still just a kid; Sans wasn't in the wrong for treating them as so on occasion. "Well kid," he said. "I haven't seen Paps since this morning. You think he's finally in the royal guard this time?" 
           Frisk shrugged. Sans looked at the ground and sighed. They continued walking to Sans' post, since they didn't have anything better to do. His eyelights suddenly disappeared as he came to the site that the Papyrus fight was held. Sans was always chilled to the bone at that awful place, but it was worse now. His eyes landed on Papy's bright red tattered scarf, and he immediately started fuming. "Frisk! How the f_ck could you do this! You lied to me-" his voice broke. "Papyrus-! Paps oh no oh nO!" Sans desperately ran to the scarf, scooping up his brother's dust.
    He faced away from Frisk, bunching up the scarf in his arms as they gasped. "I- This wasn't me! I didn't…. No… P-papyrus.." Sans' eye turned gold and blue as he whipped back around to pin Frisk on the floor. He held them down by their neck, quickly jumping to the conclusion that this was Frisk's doing. His cold, bone fingers clenched tighter around the child's throat. Frisk struggled, but managed an extremely hoarse, "w..AIt-!" 
     Sans got closer to their face. "I. Don't. Want. To. Hear. It." Somehow, they managed to kick Sans off of them, and attempted to run away. As Frisk was getting up, Sans threw himself at them, making both of them fall down. Frisk's leg bent wrong, and they yelped as they dropped to the floor with Sans on top of them. Sans immediately flipped Frisk onto their back. He harshly slammed his left hand onto their chest, and summoned a sharp-tipped bone with his right. Frisk once again yelped, blood sputtering out of their mouth from his left hand's blow. Sans dug the long, pointed bone into Frisk's chest. Frisk screamed a blood curdling scream, and tears instantly fell out of their pained eyes. Blood was now pouring out of their mouth, but they weren't hit in a vital area. Sans violently ripped the bone out of Frisk's ribs as tissues audibly tore. Blood gushed out of the wound, and Frisk lied on their back, panting in a broken way. The human drew another breath just as Sans plunged the bone back into them, going rather quickly. Absolutely drenching both of them in blood, Sans once more crushed the bone into Frisk's torso at an angle, scraping at the sides of the now large hole. 
    He began to cry psychotically, stabbing viciously into Frisk's corpse. He wailed for Papyrus, but alas, nobody came. Sans stared at the child's vacant, bloodied face, becoming eerily unsettled by their motionless. There was an odd film over Frisk's eyes, one that hadn't appeared the other times they had died. Sans had cared about them, still, so it was awful to see his pal like this. However, this wasn't his pal. He hated them, despite his half-hearted attempt to tolerate them once more. Actually, he didn't know how he felt or what to feel. Sans had very mixed emotions. Then, he remembered his brother. "No…" he thought. "We aren't friends. They killed-.... they killed him.. again.." Sans got off of Frisk, looking back to Pap's scarf. He sighed, putting it on again for the.. he didn't know how many times he'd worn that scarf. He just knew he hadn't worn it when Papy was alive. 
      Sans adjusted it, fiddling with the tattered end of it. A small, worn bit of paper fluttered out of one of the folds. He cocked an eyebrow bone. That was new. Sans picked it up, but it was blank? Sans then flipped it around, finding Papyrus' handwriting covering it. The note read;
       "Dear brother, I am sorry. I can't take it anymore, being killed by the human over and over again. You probably don't know what I'm talking about, but- I'll be back, and you won't remember any of this happened. Hopefully. I'm running out of space, I'll see you soon. I'm sorry. This was my only choice. I'm sorry..
        -Your brother, the Great Papyrus"
