Damned if that doesn't make Dean feel uncomfortable. He's so used to looking at that body and seeing Cas...he actually doesn't want it to belong to Jimmy again, not if he's being honest. Which makes him feel like a terrible human being. Which he is, so that's nothing new.

Dean ignores that. "What's that have to do with you learning how to relax? You think Jimmy's gonna be happy if you give him back a body on the verge of a heart attack because it's last inhabitant didn't know how to take a freaking nap sometimes?"
