"My place," Sans says, when what he wants to do is take Papyrus to the hospital except he's not putting his little brother in the hands of the humans who live here. The house Sans is stuck living in is going to have to do, even as Sans tallies up strange symptoms and wonders how much Papyrus is even going to be able to tell him about what happened once they're inside. "I'm loaning you my couch and I'm gonna teach you how to take a nap."

He's not really used to feeling this particular brand of concerned for Papyrus. Not for a long time, anyway. Papyrus, as a rule, can take care of himself better than Sans can. But right now--he just has to deal with this, he guesses.
