Season 4 ep. 16 "Every man in Visualize is like a son to me"- Bret Stiles,this phrase is very important i think. I think that Brett Patridge is Stiles son, and Stiles is the real Red John, i mean "the brain", the murders however are made by Brett. There are also many litle details to my theory, such as in that episode where O'Laughlin "apears" to Van Pelt he says "Open your eyes" eyes---visualize. And if we think about it Visualize is a very powerfull cult wich has many members in the police so they have acces to any kind of information. "sometimes the easiest answer is the right answer"
However, there are some episodes wich i don't quite get, for example in the episode where Panzer is killed, PJ knew that red john will go after Panzer to kill him, it wold habe benn so easy just to follow Panzer and catch RJ...this was the episode wich made me think about the possibility that PJ is RJ...but that is another theory.
