Um. Well. Yes.
There was a moment in this episode which suggested that it was all a dream. I'm going to cling to that, because so much of this made little sense, was just cool scenes cobbled together, relying on action and the big revelations to stop us from questioning the sense of it all, or noticing how many elements have been re-used from the previous series.
There's a point where all the hand-wavey just falls down. I think I'll be watching this series for the one-off episodes, rather than loving the whole thing.
