Well, first of all, Kirkland uncovered Tyger Tyger, as he told Smith during the RJ investigation. He told him that it was a corrupt group within law enforcement. Smith probably told the powers that be behind TT about Kirkland and they had to get rid of him before he blew the whistle on them. Kirkland tipped his hand to the wrong person.
Haffner could have been part of this when he was a CBI agent. Haffner could have reported information to Stiles. However, I still think TT is separate from RJ. Red John could still be part of TT though because all of the men on the list are law enforcement except Stiles. What better way to get information and form "high level" friendships? So if all of the men have the tattoo that means they all belong to TT. I think they won't all die in the explosion, that would be stupid on the writer's part. I think maybe one will be "missing" from the explosion, maybe Patrick will be also, chasing RJ, and the person missing will be RJ. I also do not believe anyone dead is RJ nor is any member of the Team. Now, are they TT members? Maybe. But RJ is someone on the list. Heller would not alienate a fan base to lie to them so blatantly as for RJ to not be on that list, if he did it would really surprise me.

Hello everyone,

I don't know who Red John is but maybe  I could Help.

So we just learned that Red John has a 3 dots tattoo. I think this clue given by Bruno Heller is not for Patrick Jane, but for us, the internet community.

Three dots is a common tattoo in the latino knowledge, it means "My crazy life" or "Mi vida loca".

"Mi vida loca" is the title of a movie directed by Allison Anders.

Turns out this woman has also directed two  very important episodes of The mentalist : 

- The first one
- "The red barn" (S05E13), where Patrick Jane makes a concrete connection between Red John and the "Visualize" Cult. We can also this the first smiley of Red John in that episode.

I think the answer is in both episodes. 

First and foremost let me preface my hypothesis by saying that it's been a fun ride watching the Red John chase from the very start and I hope the ending will not be unsatisfying.

The next three episodes are going to flow like a movie, and my theory for "Fire and Brimstone" is that Jane believes he has collected all his clues he needs to identify Red John, with the final Red Tattoo clue being the big discriminator. What Jane does not know however, which the audience does, is the whole Tyger Tyger situation.

From the promo Jane has got all 5 suspects in the room at gunpoint to finally get the moment he has been waiting for for the past 10 years-to catch Red John. What I believe will happen is that Jane, almost in a extremely simplistic way by his standards (albeit somewhat rational), will order them all to take off their tops to reveal which has The Red Tattoo thinking that whoever does must be Red John. However, the twist that I am predicting is that MOST of the 5 will have that tattoo if not ALL of them. With the tattoo relating to the Tyger Tyger organization in some way. This will initially stump Jane, but be his first insight into finding out about the vast secret organization leading into the 7th episode (The Great Red Dragon), and delaying what he thinks will happen in "First and Brimstone" but will actually occur in the 8th episode, which is the reveal of Red John.

These 3 episodes are the climax of 6 years of storytelling. It's gonna be good. :)

A few other points:

Many believe that Red John is not any of the 5 or even initial 7. I personally believe Bruno on this matter, however anything could happen.

Something more important for me just as much as who Red John is, is a thorough explanation of EVERYTHING that has transpired during the Red John storyline, I.e the He Is Ma clue, how and why do his disciples do what they do. After 6 seasons, the Red John storyline needs to conclude not only entertainingly, but with good clarity into all the clues and red herrings, not only in these S6 episodes, but the whole series. I think the fans that have stuck by deserve that at the least, and laziness in the final chapter would be a shame.

The theories will be coming thick and fast now!
