My opinion on the episode and the ending
(I could wait to get to my pc, so I watched somebody's steam through my smartphone). The Bloody Mary fight was a boring to me, and so was Crooky's trial, and to end on a ciffhanger... Seriously?
I was a little afraid that the cliffhanger ending could happen, but still I'm very disappointed. And there are many holes in the realization that Faith is Nerissa. We know for a fact that the head we found was that Faith unless a glamour could mimic the marks of her being slapped around by the Woodsman. And whose head was it then? Something is very wrong with that revelation. I have no idea if the game has other ending (if you do better with the investigation, the trial, etc.) and I won't have time to play it and experiment my different saves until tomorrow, but as for now I'm disappointed.
The game had showed much more promise than that in the 1st and 3rd episodes. The episode is short. Bigby is rushed from one scene to another, there's no exploring, investigating... And in the end Bigby is barely even given enough time and information to ponder on his verdict.
In the end, to me it felt like Nerissa(Faith) just tricked/played us from the beginning (I had a theory on that being the case, and I even nailed on Georgie being the killer if there was one, but I never thought the girl would turn out to be that "evil"). If that was really the case, and not just Bigby making a huge mistake, I think we deserved to have had a final confrontation with the girl instead of a cut to black. Either way, Bigby ended up looking like a moron. :-\
