Confusion
Papyrus was getting ready to fight the human. He summoned a large bone "WHEN WILL THE HUMAN COME HERE?" Papyrus thought to himself. The skeleton stud there, he had just shown the human the gauntlet and wondered what was taking him so long.
A small Figre approached Papyrus "HUMAN, ALL-" Suddenly, Papyrus was interrupted. "nah bro it's only me." Sans said chuckling. "OH..." Papyrus said disappointed. "hey bro, can i fight the human?" Sans asked his brother. "YOU WISH TO FIGHT HIM?" Papyrus replied in a confused tone.
"yeah since he's only a child you'd probably kill him by looking at him since you're so strong, it's best if i fight him instead." Sans said. "HMMM ALRIGHT THEN, I'LL BE IN MY ROOM, COME TO ME WHEN YOU'VE CAPTURED HIM!"
Papyrus said in a prideful manner "I'M GLAD YOU'RE FINALLY DOING SOMETHING FOR A CHANGE." Papyrus added as he wandered off. After a few minutes a small figure approached Sans. "heh kid, surprised to see me? don't act confused kid, you know i know about the resets. I don't know what happened but i know they happen.." Sans chuckled to himself. "look i know you decided not to kill anyone this time around but... look kid." Sans sighed. "that look in your eyes tells me that you've fought me around four times now and you're angry because i kill you when i spare you, so the only real choice is killing me or giving up ad we both know that you'll never give u-" A punch cracked Sans' skull. "After the forth reset I promised to kill you before you even started the fight." Frisk smiled as he punched Sans again and again until his fist went through his skull, blood stained his hand as Frisk took off the tough glove and got out a knife from Sans' kitchen and rammed it through Sans' ribs. "heh kid, when will you stop?" Frisk smiled "After this run I'll do another pacifist run and then I'll stop the resets." Sans smiled again "just be careful of papyrus, when he finds out what you did to me... he'll" Sans was cut of "Give me a bad time yeah I know." Frisk walked off as Sans dissolved into dust.
"SANS IT'S BEEN FIFTEEN MINUETS, HAVE YOU CAUGHT THE HUMAN YET." Papyrus walked through the fog until he say some clothes on the ground. "GREAT, HE'S NAKED, STRIPPED HIS CLOTHES, DROPPED A BLOODY KNIFE AND LEFT IT ALL IN THIS... Dusty Powder." Papyrus dropped to his knees "...Sans..." Tears fell from his face "Why would the human do this..." Papyrus saw the Knife on the floor. His picked it up... "I'll kill that Bastard.."
