I think it must be Reede Smith. During Red John appearance in season 2, the actor Drew Powell was thinner. He now has short, straight hair and is a bit fat. He easily shows his anger, but Heller stated in an interview that RJ could be him with psychopathic anger masked by anger. That is the best way to hide it. Everyone believes that since he cannot hide his anger, he cannot be RJ as Rj is cool, calm but who knows Smith might be putting on an act as displaying his anger.

Hi guys



This is my theory:


There are two organizations, Tiger, Tiger and
RJ organization. Those two organizations are in war, and war became more
serious, when RJ killer Brett Partridge. Partridge is member of Tiger Tiger
organization. Bruno Heller said that there is clue in S06 E01. That clue will
have more sense at the end of the story. We all will understand that clue at
the end, but in my opinion that clue is when Partridge said Tiger Tiger. That
is evidence that Partridge was member of that organization.

Ray Haffner is RJ, because Rosalind Harker described
him, and he is Visualize member, and he could be on that farm, where RJ killed
his first victims.

Todd Johnson was a cop killer, and I think he
was killing police officers that are members of Tiger, Tiger organization.  Kira Tinsley was hired by Tiger Tiger
organization, not by RJ, and that is reason why someone from Tiger organization
murdered her. She had to bug CBI offices, because Jane would figure out if they
send some police officer. It is much easier to send someone from outside.

Craig O’Laughlin and that Sheriff from final
episode of last episode did not have tattoo, and we are sure that they were RJ
friends. They were cops and why they did not have a Tattoo.  That is because they were friends of RJ and
not members of Tiger organization.  

Betram wants RJ and that is why he is so eager to
be there when Jane catches him.  

Why Kirkland killed Jason Lennon, which is one
question that I cannot understand. I think that producers want to mislead us.

Hello, everybody.
This is not really theory, rather what we should think it really happened when Heller and the production ruin the whole plot with absurd explanations, dumb motives, pompastic twists. I believe that not only Heller had no clue about RJ identity when he gave the interview on season 5, but as well that the show starts to fall short of logic. The last thing is Partridge dying with the words Tyger Tyger in his mouth, instead of "Get X (here be RJ true name". This is so lame, unoriginal, and not the only stupid behaviour seen on the show starting from mid season 5 (for ex the Lorelei episodes and PJ, the titular Mentalist, incapable to make her reveal RJ identity...).

So, the only satisfactory eplanation NOW is that RJ is one of the Kirkland brothers. Otherwise you can't explain season 5 scene with the wounded RJ disciple in the hospital. If Kirkland is so determined to track down RJ to even resort to torture, he would have had no point in just finishing him off instead of getting the name out of him. The real RJ, his twin, would have acted like this. Besides the "fearful symmetry" clue, as someone has already noted, perfectly fits with the "twin" (triplets also allowed...) contrivance.

Every writer, screenwriter, storyteller (and viewer) knows that when the talk goes about twins, you should expect something cool happening...
Hope you didn't cock it, Heller.

What if the "clue" at the end of S6 EP1 was...

The odd double-take Lisbon did on the street...before...she went in alone.

It's as if she recognized someone, but, not someone she is close too...I.e. Bertram, Haffner, Mccalister, Stiles or Smith...if it was them, wouldn't she have assumed they were there to help or at least she would of reminded re team of a sighting?

I think it MAY end up being a clue...

My bets on a "blast from the past". You remember Mr. Mars don't you?:). Second guess would be...yours an my favorite Walter mashburn! Soon enough I suppose
