According to the mentalist website, The Great Red Dragon episode synopsis is 

"Following the shocking events at Jane's house, the Red John suspect list is narrowed down further and the CBI's priority is the remaining suspects."

Who's gonna die next week ?

title "Red John"
cast "Gale Bertram"

It must be Bertram. He controls the law enforcement network but nobody knows he is RJ since he pretends to be part of RJs network. He is hiding in plain sight.

 He works with Stiles who controls the Visualize network. Stiles knows Bertram is RJ and Bertram lets Stiles do what he wants with Visualize :)

Bertram is happy to let Jane think Stiles may be RJ. Stiles controls Haffner and Haffner keeps an eye on Stiles.

The paragraphs below are not necessarily linear, it is more of a compilation of my thoughts on the season up to this point:

     Up until this week I thought for sure Haffner was RJ, however following this weeks episode I am almost positive it isn't him simply for the fact that he wouldn't have needed a private detective to bug the CBI as he was working with them and very well could have done it on his own. Additionally, I think that because Haffner has had such an eerie presence in most of his appearances this season, it only adds to my disbelief and makes me feel as though it is a clear red herring from the writers.

   In a post a few weeks back, I also said I felt someone on Jane's team (Cho, Rigsby, or Van Pelt) had to be more involved with RJ and that we would soon find more in coming episodes. If RJ really did have an accomplice working directly with Jane, why would he bug the office? Although I still have my doubts about Van Pelt, I think what I said earlier may very well have been false.
 
     After this next episode, I believe we will learn one of two things: either none of Jane's suspects are correct (which is impossible given Heller's statement is true regarding the validity of the list), or at least two of the suspects will escape the explosion from the promo leaving us on a total cliffhanger. To be completely honest, I don't have a clue who Red John is and if you think you "know" anything (excuse my French), but you are a jackass. I would love to see Stiles or Bertram, but I can't wait to see how things unfold!

You guys are impossible, going where Heller points you. Some episodes ago you were all on pidgeons and that they are RJ's phobia and now you have seen little spider and Haffner's reaction to it and sudenly it must be him. I admit Haffner fits it nicely (private detective hired by Visualize) but I bet it's Bertram (or McAllister cause it was said that we will be disapointed) and he is super-cunny leaving trails that leads to other suspects 

hahahahahahaha this is very funny, i have entered this website all days, and now that we have seen this episode heller has acomplished his mision ... admit it..

NONE OF YOU HAD A CLUE WHO RED JOHN IS.

RJ IS GALE BERTRAM BECAUSE HE IS BALD
