Summary
(rewrite)
He flinched hard as a skeletal hand bigger than his torso came to lay on his skull, gentle in all the ways it shouldn’t have been. It simply laid there, claws careful not to nick him, before warm breath came next to his head.
“Good boy. I will take care of it.”
Sans blinked, tears dotting his sockets as it finally backed away, staring down in him with an unknowable expression.
“You… you will?” Sans asked, voice trembling, quiet and meek. It stared for a moment before nodding once.
“Yes. But it will not be pretty. Go to your bedroom, shut and lock the door. Do not come back out until I tell you it is okay.”

Okay, so admittedly none of this has gone entirely according to plan.
Actually, most of it did the opposite of that.

OR:
Sans runs afoul of some pirates once or twice, and it turns out there are a lot of things he doesn't know about the universe at large - things he really wasn't ever supposed to learn.
