I`m watched again S02E023, Red John touched the Jane's shoulder. (Roll tide?)  Now look at the S04E02

Haffner touched the same way Cho's shoulder. 

coincidence or a clue?  

I really don't think it's Haffner, RJ is very controlling and egotistical. Haffner is a member of visualize , do you think rj could stand not being in charge?

To all the people who say that RJ is Michael Kirkland- wouldn't it be weird for RJ to turn out who only joins at the last moment? Also, Heller said that we already saw RJ. Now you will that it was Michael that killed Lennon in the hospital, but why would he ask him if he recognized him? Surely if he is RJ, then Lennon would know him. Especially as he led RJ to Lorelei's sister. Additionally, twins don't looks exactly the same after 40 or so years, their appearance changes depending on their lifestyle etc. We know that Michael was an alcoholic for some time, whilst Bob was leading a relatively healthy life.

rj is ray haffner because he has the weirdest face when he is pumping himself and because he likes lisbon and he wants to have sex with her all the time

Cmon guys, stop with the Jane is RJ bullsh*t!

To me there are only 3 viable suspects from the list

1) Ray Haffner
2) Gale Bertram
3) Brett Styles

It can't be Reed Smith as he's just a fat peice of lard who needs to lose some weight.
Can you imagine him commanding loyalty off people, and hypnotising them?

LOL

according to the notes of the psychiatrist red john likes to whistle. but the video at that time pointed out to  thomas mcallster whistling. but as he is not afraid of heights so he might be rule off.
in the hospital when ray haffner came to visit lisbon he whistled while he was leaving.also he is the only one suspect who has been introduced but not acquitted. 
reede smith will be a member not the boss

I believe that at least three people on the list are involved in the whole tiger, tiger group Gale Bertram, reed smith(this was confirmed last episode) and Ray haffner. I think that either haffner is r.j and the other two are working for him or r.j is Brett stiles and haffner is using the other two to gather information.
