[It's not as if William's the first person who's responded to that news by looking for wings. The glance causes Castiel to shift both wings in against his back, not that it would be visible to a normal human. But it's a self-conscious response to being scrutinized.
He can see that even in his drunken state, William is doing his best to sort through this revelation. Castiel has nothing but time, and so he doesn't mind waiting until the implied questions come in. He doesn't know what to make of the knowledge that William actually likes his version of Michael, although there's something else he says that's more alarming.]
... Did Lucifer throw you out of a window? [He's heard more shocking things, yes, but Castiel spends a lot of his time here hoping that his brothers don't make trouble. That's obviously too much to ask for.] I apologize for that. I'm not an archangel, but I am related to both of them.
[It's clear that William's completely lost his train of the thought, and the sooner that Castiel can get him to a bed, the better. He takes a step toward him.]
