Too bad there will no season 2 but I think of two possible things on how it will ends. All the research about him was just a coincidence about the character he was playing, I mean its not connected to what he was doing, like studying with wallace, being a trickster. The end part of the season proved it when he revived two men with a kid witness OR the kid is part of the trick and everything about him is right, being part of a greater terrorism with wallace, etc.
