Oh cmon guys Bruno Heller is a mastermind, how can you be fooled by a sentence such as Bertram's: when you catch red john i'll be there or when the psychoteraphist says that mr. ROTH is a good whistler and McAllister is shown after,... You must look at the smaller picture, I can guarantee Bruno has our eyes and minds compleatly messed up with those ''BIG CLUES'' but in the end, like said before, the birds which are shown in many different episodes ( all include RJ ) will be the main clue to RJ, or something like that.. 

So i must say that I think that no one of the seven is RJ, they are all his friends and they know about each other ( the meeting ). I also think that Bret Styles is RJ's father, and Bob Kirkland is RJ's brother. I must also say that Teresa Lisbon might not be murdored ( yet ), because she is the weak part of Jane, he would do anything for her and I think RJ will soon start to use her as a bait to mess with Jane. So I must say that I dont know who RJ is but I will say that we are missing something... Bruno Heller GREAT JOB :) <3
