Ok, well if you look at the scene where the gun shot happens the light comes the window on the left, where Ray was sitting, not from the right window where Patrick would have been. So I believe that Patrick didn't shoot anyone at the end of the episode. 

I also believe that RJ is separate from Tyger Tyger and that Tyger is being used to throw us off the scent of the real RJ, which is Haffner. He fits the descriptions given previously and so I'm sticking with him for now. 

Smith killed Kirkland because he found about a secret organisation while investigation RJ. Smith figures that PJ will also find out about this organisation wirh his own RJ investigation so Smith sends the PI to bug the office to see if PJ truly has info on the organisation. When she is caught he figures she is too much of a liability and kills her. This is why her killer has the tattoo. The tyger tyger org members have the tattoos, I dont't think RJ does.

I think PJ lets Ray and Stiles leave and if you look closely there is a car that looks like Smith's car just as Lisbon is arriving at Jane's house (when she crosses two cars and gets beeped at). I think Bertram, Smith, Mcallister and Jane are in this car.

My guess is it's haffner. We can't forget red barn episode. RJ is associated with Vizualise and did you see how Stiles painted the girl with the blood. As RJ admires Stiles, he would have used the writing of the blood in his killings.

This last episode was amazing....although I cursed at PJ for tricking Lisbon (and us viewers). My heart broke into tiny pieces. She was teary and happy about what he was saying and the hug and he played her. Shame on you! :)

I have just remembered a scene from a few episodes back when PJ was in Bertram's office with some of the other RJ suspects, PJ said he was getting closer (or along them lines). Once PJ leaves, Reede Smith asks Bertram just how much PJ knows, to which Bertram say's "that is the question" and he say's it in quiet a creepy way, not in a way that he is just frustrated because Jane is being secretive.

He has been in it long enough for Hellar to have a "look all this time he was RJ" moments.

The actor who plays Partridge has said himself that he is actually dead, so that would rule him out.

I personally have two suspects which would fit my profile of Red John.

Brett Partridge: They said there is something special about Partridge his death and I like to believe he returns. The Theory that Stiles is his father might be true, maybe Patrick really wants to kidnap Stiles to get Partridge out of hiding (Because obviously Patrick knows already who Red John is, he is just playing his games). Saw the promo for a Criminal Minds episode coming out soon? Look who it is and the voice is similar to Red John. We all know the other clues that lead to Partridge, so I won't list all of them now.

Here the video of 'Red John' on Criminal Minds: http://www.youtube.com/watch?v=XGbq8LuACeg&feature=youtu.be

Maybe Heller wants us to believe it is Partridge, in that case here is my second suspect: 

Ray Haffner: (In case he didn't die now) 
He was my suspect from the very start and I still hold onto it. When they gathered all the suspects together, he was the only one asking Lisbon to drop the Red John Case after, why would he want that? Because either he is involved or he is Red John himself. He is involved into Visualise as well and stuff.

BESIDES

The other three are involved into Tyger Tyger, which will go on when the Red John case is done. The woman last week was killed by one of those three or another memeber of Tyger Tyger. It was never Red John who bugged their office, it was the organisation. The murder was unlike Red John anyway. 

Let me know what you think

Okay guys lets just be cool for a moment and think straight.After the last episode there are 3 possibilities in my opinion.

First Possibility which i hope is not true i will personally be very dissapointed is that Red John is not a single person it is just this 'Tyger Tyger' organisation in law enforcements and thats why it is very hard to caught him because there is no Red John there is just only a bunch of strong connected law enforcements officers who help each other.

Second possibility is that once again Bruno Heller tried to confuse us.I believe a lot of you including me believed that Red John was Timothy Carter from s03e24 and waited for a whole summer to see what is going to happen.So there is a strong possibility to make this happen again.So if this is happening either Red John was off the list of 7 from the beggining or is Brett Partridge.If it is someone off the list i will be very dissapointed also cause NO one can be Red John...And dont tell me about Ellis Mars(OMG) or Walter Mashburn or even worse CBI Ron...If it turns out to be out of the list then Bruno Heller better stop writing.But if Brett Partridge is Red John then Bruno Heller is very smart.I am saying this because before this season most of people's number one for Red John was Brett Partridge...Bruno didnt liked that and wanted to take us away from Partridge so he "killed" him and trapped us once again to believe that Red John is someone else from the list.

And the third possibility which i believe would be the best is Red John being one of these 3 men.Gale Bertram , Reede Smith , Sheriff Thomas McCallister.Of course that means he is the leader of this "Tyger Tyger" thing and thats how he can go away with so many murders...If the third possibility is true then we have to think from the beggining.We have to think the "He is mar" ,,we have to think Rosalind Harker's description ,we have to think the body type of Red John in s02e23 we have to think Rebecca's reaction(s2e08).From the description and the body type of RJ in s02e23 and also by thinkin straight we have to rule out Reede Smith.Come on now you believe that Bruno Heller put RJ in the show in season 5!!!! and made him a fat guy with violence tenses...Come on RJ isnt that type of guy.So Gale Bertram or Sheriff Thomas McCallister or Tom as he wants from PJ to call him...Or RED JOHN as i call him...Xander Berkeley is a great actor and its odd that he played only in one episode and was chosen to be one list.Im sure non of you when you saw the list remember this guy...And its also strange that the mentalist writers made him younger.This is odd isnt it??I am saying because he has to fit in age with this young man that possibly wil play the young RJ in the next two episodes in the Elliston farm.

1)RED JOHN IS JUST AN ORGANISATION(I LL KILL YOU HELLER IF THIS IS TRUE :) )
2)RED JOHN IS EITHER BRETT PARTRIDGE OR SOMEONE ELSE OFF THE LIST(ILL KILL YOU TOO)
3)GB or RS or TM...and my pick is TM(Thomas McCallister)

Glad to read your thoughts!!
