I think that Tristan is the 10 Commandments copy-cat killer. The one we saw in that house with the cane...
But can I just say this is shaping up to become such a great season. Everyone (sans that little Holden ****) delivered their lines amazingly and Gaga improved tenfold since her previous episode

Like I don't even see her as 'Gaga'.
Did anyone else think the girl who was sitting next to Gaga (drinking her blood i guess?) was Angela Basset's character? (in the 70s disco scene)
Episode 2 >>> Episode 1 >>>>> whole of freakshow.
Edit: Also Mare's character was my fave this episode. So amazing.
