OK, I just had a couple of revelations about this episode:
1. That was a really cool scene where the Doctor talks to the Minotaur and we only see them both in mirrors. Why? Because it's symbolic. The minotaur is a reflection of the Doctor, as we discover at the end of the episode. Pretty fucking cool.
2. RORY KNEW. When the Doctor asks him if he's found his room yet and he says no, the Doctor says "Maybe you aren't afraid of anything", to which Rory replies "Well, after all the time I spent with you on the TARDIS, what else is there to be afraid of?" or something like that. The Doctor points out that he said this in the past tense, which Rory denies. Anyway, the point is that RORY FUCKING KNEW.
.....HOW DID HE KNOW??!!! Was he just planning on leaving the Doctor soon when he said that? WHAT WAS THAT??!!
