Facts:
1. Kirkland is dead. 6 left
2. Bertram + Smith + Mcallister = Corrupted police ( Tiger - Tiger ) led by RJ so possibilities is they are not RJ
3. Haffner was police and still is Visualize.
4. Patrick got a clue that is massive ( tattoo of RJ )
5. Pattridge has the most similar voice to RJ
My thoughts:
In season 5 if im not mistaken patrick and his team invastigate a case at an old farm house which was controlled by VIsualize and had the red john face on its wall from long time ago.
Detective said that she was hired by visualize before she got killed by her client ( RJ )
As stated by the doctor RJ has phobias and haffner seems to be scared of things
They say that RJ controls many people and so does Brett stiles from visualize
My Conclussion
RJ is 6 men:
Pattridge = his voice
3 agents ( FBI , CBI , POLICE ) his eyes and ears
Haffner = his hands
Stiles = his brain and leader...
What I am not sure though is that red john appeared as a person to the doctor and she concluded but a visualize member would never do that because they all some how find inner peace at that place.
And more interesting is that RJ never makes mistakes that are THAT obvious to patrick...
