Superpowers, magic - Connor's not really bothered about the difference personally, but he makes a note anyway. What Jane and her alters do - superpowers.

He tries not to look down at the sweater because if he does, he'll have to agree.

"OK. Let's assume it won't work on me." If it does, Connor isn't going to be any help, and this is going to be one hell of a night. And one hell of a rest of the year, considering he literally shares a room with his actual partner, who's not going to appreciate this. "I could probably stop her from going at all. Or would you rather I just stay with her all night and make sure she gets back here by herself?"
