Just to clarify about the Kevan scenario:I didn't write that to be coy or anything. Our source honestly wasn't sure if it was Kevan (Ian Gelder) or not. However, the fact that there was a man who looked like him in the company of Qyburn and the Mountain would seem to indicate that it is indeed him... who else could it be?
Yeah, unless they just couldn't get Kevan back so they've introduced some new Lannister uncle who is exactly like him, it seems likely that Kevan is in.
