Guys, this season has something that bothers me. In
previous seasons RJ was presented as a brilliant mind, as good, or
even better, than the PJ, with many connections, disciples, very persuasive and a lot of power power. This guy played with PJ when wanted sor several years, he is arrogant and a very powerful man. None of the suspects seem to fit in this profile, unless Brett Stiles but I think he is too much obvious.

This
season we are seeing a different RJ, more fragile than
previously presented, to the point of hiring a cheap detective to put in
trasmissor in CBI office, totally contradicting his image of very well
connected man, full of resources and powerfull (and this kills the
theories that Bertram, Hafner or Smith can be RJ since they had free
access to the office in previous episodes, Bertram work there and Hafner
could do it easly in this epiosed since he was working with CBI).

Also
the phobia stuff sounds a lot off to me, I do not know why. I will be
very disappointed if RJ is one of the suspects because none of them fit
the profile presented in previous seasons. My opinion is that the
suspects are part of a secret organization that hunts RJ, and not that
he is their leader. I believe we will have a big surprise at the end and
that RJ is someone off the list and no one we expect to be.

The Mentalist Season 6 Episode 6 : "Preview"

I Just have a couple of thoughts after the last episode.

1.) The writers are doing a good job of giving the different suspects their "moments" and now that Haffner has been featured "again" it's making him seem like he is too obvious a choice. But is that another trick?

2.) Does anyone else think Van Pelt is going to be the casualty of Red John? With the announcement of her and "Rigsby" leaving the show it's plausible she gets killed and Rigsby leaves in despair ( I don't think they will kill Rigsby off as he has a child).Or is it another "trick" as we haven't heard anything about Cho going or staying. Maybe he will be the victim and none of them are coming back?

3.) If Haffner is RJ then Grace sarcastically telling him he did a "bang up job" protecting the dead guy probably wasn't a great move. Would this be seen as "insulting" him? Theresa is noticeably always very polite to him even when he is rude.

4.) Does RJ seem more careless and sloppy now? He has to use low end P.I.'s now when he would have had a mole on the inside before? Are we to assume Jane is getting to him and he's flustered?

5.) Ray clapping Jane on the shoulder like RJ again- more misdirection from the writers?

6.) Jane seems awfully cool and detached despite getting closer to Red John. Also, did no one tell him about Kirkland's death? Was he expecting it? Shouldn't he have been involved in the discussions about it?

Bret Stiles knows who Red John is and they are working together to take down the Tyger Tyger corporation.

There was a very popular theory I read months ago that Red John is the son of the old leader/founder of Visualize. It was the best theory I had read at that time and now I am going to expand on it because I believe it is true.

Here is a line from the poem 'The Tyger' by William Blake.
Did he who made the Lamb make thee?
Did he who made Visualize, make Red John?

I also believe the Tygers framed Bret Stiles for the death of Red John's father (The old leader of Visualize) and Bret Stiles is innocent. Red John knows this so is on a hunt to take down the Tygers.
