They haven't told us either way on a Season Four, but I don't expect them to until after next Sunday anyway. More tension that way.

I think Mitchell will get his by the werewolf shaped bullet. All the other guns on the walls have gone off, so there's no reason that won't. But I think the Zombie ep was there for a reason, and if we don't get a new season for Hobbitt related reasons, it would be the built-in loophole I'd use to get M&A back, as I'm sure she'll do as she said and go with him.
