You’ve been resetting over and over. You usually did pacifist routes so Sans didn’t care that much. But you’ve just reset a genocide route, that you finished. You decided to do a pacifist route again, but you knew some guy wouldn’t be happy about your return: Sans.

You just exited the ruins and you were walking toward Snowdin. You heard a branch snap.

“Don’t you know how to greet a new pal? Turn around and shake my hand.”

you turned to see Sans. You shook his hand and heard a fart noise.

“Whoopee cushion in the hand prank. Works everytime.”

he leaned forward and whispered something in you ear

“Why are you here? Are you going to kill everyone again?” he said, sounding threatening before acting like nothing happened
