I'd be curious to see more discussion on the comments from the poster who wrote the "spoiler" based on cast list (quoted below). I have a hard time accepting Bertram as RJ. Seems like he was an afterthought cast addition once the show was underway. I also find it unlikely the more comments I read that any of the 3-dot crew are RJ. Heller was already frank about the list of 7 being real, so it's almost like he gets to throw us off with a "fake" list of three.....Considering that and based on other commenters, I am now leaning to Ray or Stiles with a small window of plausibility that it could be Partridge or Kirkland undead. I also like some of the theories that someone on Janes team is duplicitous, amybe not with RJ but maybe with Tyger... if so, I'd vote for Cho. We are all looking to be shocked about who is Red John that the big surprise could be something else.

"...spoilers for the next episode based on pictures, cast list, and sources.
dont read this if you dont want to know who the real rj is.
and i dont care about green or red votes because this aint a theory.
s607 - sherrif thomas mcallister dies.
s608 - reede smith gets arrested, red john will be gale bertram."
