I'm afraid i'm right that misterious character Sean Barlow finally revealed as Red John. So Jane and RJ met and shook hands in the carny in the past. Don't you think Jane shouldn't remember that he met in the past with currently RJ suspects (Partridge, Bertram, Kirkland, Minelli, etc...).??? Or they shook hands in the present, and Jane doesn't remember he met before any of them???

I think Red John will be a new character...

Other snippet

SCOTT ANTHONY LEET will play the role of Roddy Turner. He is described as follows.



Early-mid 30s, Anglo-Irish with an Irish accent, physically imposing,
from the carnival circuit, this tough young man can erupt into violence
at any given moment. Even though he's a prime murder suspect, he seems
genuinely distraught at the death.

I wonder if in 5x17 when PJ and Lisbon are in the middle of a questioning some random dude opens the wrong door. Why would Heller just add that in randomly? 

Robert Kirkland is the guy I'm talking about.
In some episode of season 5 He SHOOK the hands (before Lorelei Revealed that detail!) with PJ and then Patrick asked, "Do I know you?"
and he said, "You don't know me, but i know you".

P.S.: Both RK and RJ have letters in the name... it's obvious (kidding)

I think that Red John was once a prominent member of Visualise, hence why Brett Stiles knows him. I think he worked his way up through the ranks, but somewhere along the way corrupted the teachings of the cult. He uses his natural charm and influence along with Visualise teachings to create his own sub=group of followers. This is why he seems to have contacts all over the place including law enforcement and FBI. It's already been established that Visualise members are everywhere and don't always let their "faith" be known.

It is possible that Red John is an organisation of it's own, with the leader ordering hits on the various victims, while keeping his own hands clean at this stage. He could possibly teach his disciples his methods in order to keep the killings consistent. That would explain how his victims are killed so quickly when they are exposed as a lead (as in Red John's Friends when Jared Renfrew is already dead by the time the team reach him).

Also the message left behind "He is man" could indicate that Red John views himself as a higher power or even god-like figure, leading us back to Red John being a member of Visualise. It's possible that  Red John is bringing new members into the organisation, which is why Brett Stiles turns a blind eye to his other actions. Either that or he is Brett Stiles son, groomed from an early age to be the next leader of the organisation, and therefore been treated his whole life as a saviour.

There is a possibility that RJ is not one person but several. The first RJ started in 1988 with the Red Barn killings but then someone else started it up again around 1998. It's unlikely but it could of happened so Jane might have killed one Red John.

I think red john is the guy from homeland security, why should he be so obsessed with lorelay martins
??????

The guy at the very end of s05e17 moving over and his back being visible on the glass wall... Maybe working with the CBI...
