What if none of Jane's suspects are Red John? Red John knew the list before Jane, and therefore figured out how Jane got to that list and could've planned it all from the beginning. He could've purposely made Jane make a list of people who could be Red John, but really isn't. If he wanted the people on the list killed, he got a target on their backs....without getting directly involved and in the promo for the next episode it shows Jane threatening to shoot all the suspects.......though that's probably not gonna happen....but that doesn't mean one of the suspects he gathered in the room is Red John.
