"SANS!"

He sat bolt upright in his chair at the sentry station, fully awake now thanks to the fearful scream of his younger brother. No.. he didn't think it would've been one of these runs. Then again, what did he gain for falsely placing his trust in the human?

"hang on paps!" He shouted, scrambling up and forcing his eye to glow, "i'm coming, just hang on!" He tried to shortcut right to where he knew his brother, Papyrus would be, but it didn't work, why didn't it work?

"of all the times my weakness shows itself," he muttered, kick off his fuzzy slippers so he could run without tripping.

In less than a minute, Sans made it to his brother's remains. A pile of dust, and his signature red scarf. He fell to his knees, clutching the scarf to his face, covering the tears that leaked from his eyesockets.

"i've seen this dozens of times," he choked out, his eternal smile painful now, "and, gosh, it still hurts."

"That's really no surprise is it?" A voice in front of him asked, "Considering it never changes that you fail him."

He raised his head and met the red eyes, the evil eyes of the kid. "frisk," he growled, not even bothering to stick to the script if the kid didn't.

"Actually, no," they tilted their head with an innocent smile, "But that's a great guess, Sansy."

"you're not..." he stood and gave them a laidback smile, "well we haven't properly met, that's no way to meet a new friend."

"This is no time to joke, Mr. Comedian," they giggled slightly, twirling their knife between their fingers, "You know me. After all, I've killed both you and your brother at least a hundred times by now."

At this he flinched, shoving his hands in his jacket pockets to hide it. "so humor me," he said coldly, "you obviously know my name, it's only fair you give me yours."

"Now now Sansy," they gave him a mischievous smile, "No need to be so rude. And you don't need to know anyway, it's more fun to see you tear yourself down guessing."

He glared, trying to hide the fear at how different this was. "well, if you really are the one behind all the genocides," he wrapped the scarf around his neck, "you're in for one bad time."

He went to turn their soul blue, so he could initiate the battle and attack, but he couldn't raise his arm, couldn't move. He struggled for a moment, then met the kid's eyes, "what did you- what did you do?"

"I didn't do anything," the innocent smile widened, "I thought you already knew how weak you were, this is all you."

"no- no it's not-"

"Geez, you're more in denial than I thought, lazybones," the creepy giggle, "I guess you really are hopeless."

"you don't know what you're talking about," an unseen force pushed him back to the ground.

The kid stepped forwards, using the end of the knife to force him to raise his head, to look them in the eye, "Its time you join your brother. And have fun explaining to him how you failed both him and his friends."

And with that, they slashed open his ribcage, sending him back into an immediate white light.
