Sans the Skeleton

You were with Sans at the MTT Resort, having the typical dinner with Sans since you already knew this part and knew it would go the same way. You were sitting in the chair in front of Sans
You know that if I had never made my promise, you'd be dead where you stand?
He asks seriously but then laughs sarcastically
just kidding, I do my job really well, you haven't died down here a single time!
Sans makes a somewhat mocking face, rests his skull against his hand, and stares at you with his smile
or... am I wrong?..
Sans's voice is somewhat sinister; you get nervous knowing that he probably knows about the resets and the timelines you've created

I know what you've done kiddo
