Hey, I don't really know why but I have hunch which tells me Faith is probably alive. 1. You only find the head, not the rest of her body; could've been someone glamoured to look like her easily. It is really interesting how this game is trying to screw with our minds and I liked Faith a lot, I hope she will return in EP5 even if she reveals herself as an antagonist. I saved Prince Lawrence, I just like those two characters. 2. Beginning of the game, Faith leaving the scene after you beat Woody; she rose her index and her middle finger up saying: "See ya around." Same hand, same fingers, same phrase with Mary in the ending of EP3 3. Both of them seem to wield Woody's axe really good, as you can see Faith smashing it into Woody's head and Bloody Mary almost doing the same with Bigby. Just a theory, nothing too extreme tho.
