I think Red John is Kristina Frye. She is one of the few people that have the same skills as Patrick and appears to manipulate people with ease. She is also one of the only people that Patrick has had problems reading.

All the evidence points to Red John being a man.. the witness statements, the rape... But if we think about RJ's track record he has always used accomplices and at least one of his accomplices convinced the CBI team that he was RJ himself, therefore I don't think RJ has to be a man. I think RJ has to be someone who can manipulate men to pretend to be RJ. The rape was also not committed by RJ but by the man Lorelei killed in the last episode.

Women are more hated as criminals, it is somehow more shocking and dramatic (which is what the producers are looking for) for RJ to be a woman, especially when all evidence appears to suggest he is a man.

Kristina'a storyline was unbelievable. She was sure that RJ would not hurt her when she spoke of him on TV. This is not a conclusion a normal person would make from looking at the evidence. She then 'vanished' whilst under the guard of Van Pelt (who has also gone a little crazy since spending time with Kristina in my opinion). There was no apparent disturbance she just vanished which incriminates one of them or both of them to me. She is also the only person (to my recollection) who has survived a RJ kidnapping aside from PJ. Her appearance after her abduction was equally strange and unbelieveable. It is also incomprehensible that PJ would have just given up on her after the few minutes of trying to make her talk. She is the only survivor of RJ and she was very close with PJ, you would think he may at least visit her in a later episode.

RJ is a master manipulator with the same skills as PJ. Kristina shares her brilliance with Patrick in manipulation.

The letter RJ left to PJ when he killed his family taunts him about not being 'a real psychic'. Kristina is adamant that she is 'a real psychic.' Obviously real psychics do not exist so Kristina is not to be trusted.

Kristina and PJ shared a connection that explains their fascination with each other on another level - neither like to be outsmarted and both like game-playing.

Kristina appears to be about the same age as RJ may be and we didn't find out about her background.

RJ would not have spared Kristina's life. Also Kristina has sat happily out of view for a few seasons now so that we all forget her.


 

Regarding "he is mar"

I think that Jared was trying to write "He is married", and that while he did not know Rjs identity he knew he was married. Which gets me thinking about Rosalind and how she could fit in if in fact RJ is married. Also it could be like how Jane told that woman in the bar he was married even though his wife was dead. It is possible RJ has a dead wife as well, maybe someone Rosalind reminds him of. 

I think that in order to find RJ, Jane and the team will uncover something, somehow about his wife that can give them a lead. Maybe this mystery woman could be someone RJ met on the visualize farm, or that she died when he was working on the farm. 




I think that Lorelei will have let some sort of clue for Jane because she knew very well that she could die I think her way of saying thank you to Jane for finding the truth about Miranda will have been to leave a clue behind. 
Also I used to think Kirkland was RJ but i think that he is just a small pawn in RJs operation and his scenes are only to add suspicion, I don't believe he is a major player in this. 


Let me know what you think, agree or disagree?
