First of all I would like to say that the rest of the theories were amazing and very convincing to read. Thanks for the deep insight on the plots.
I believe that the red john is either Patrick Jane himself, or a inside member of CBI that Jane has been working with all along. Just a quick tangent- do any of you know why the episodes after the red john episode aren't with a form of red in the title?the titles are either green or something else with different colors. I thought that was interesting.

The amount of episodes and seasons put into just one villain makes me feel like the creators had in mind that they wouldn't give us a direct list of the people to expect. Why would they make it easy for us to figure our red john? Jane could have an alter-ego self that knew everything about him and was the reason why he can't defeat this villain. Being the genius that he is, jane would make the perfect Red John. Red john needs to be someone that we never expect and thst knows Jane so well that he predicts what he will do at every moment.

My other theory is that it might be a partner of jane that he works close with such as Lisbon or Grisby. Lisbon knows Jane so well that Jane trusts her fully and would never doubt her. She is at all times is knowing what. Jane is doing and Jane looks at her as a partner to stop the villain. She would be a perfect villain working in the back scene without a suspicion by Jane that she is red john.

Ps, I found the reed smith translation of his name into the red or whatever very interesting considering the amour of symbolism used in the shoe such as Tiger, Tyger. The creators are smart.

PLEASE LEAVE FEEDBACK AND ANSER MY QUESTIONS, I AM DYING TO KNOW!!!!
