In my all previous theories (PLEASE CHECK) before broeadcast of episode 4 ;

1- RJ is not a person on the list
2- There is a secret society (becuase CBC channel is a secret society's channel and this serial includes lots of masonic-illuminati symbolizms in backgrounds) 

Now , people just be clever and understand the mechanism

This serial is based on the sense of making more surprising and giving always the unexpected thing. Now ,like a fold, everyone has already been manilpulated and misdirected to this 7 people. BUT RJ WİLL NOT BE ONE OF THEM. 

Final facts that you will understand in future episodes are;

1- RJ is a person
2- RJ leading a secret /satanic organization
3-Tyger Tyger has more greater meaning, but Bertram,Reed or Sheriff kinda of this people only allow to know the organization on this level.Tyger Tyger will be upgraded to more mysterious meaning in future episodes.
4-Bret Stiles is being awaited ,because Heller wants people think him RJ but untill Bret sheriff, Ray ,Bertram will be eliminiated respectively.

5-Stiles will stand alone , he will guide PJ to see who the RJ is ,Stiles knows who the RJ is, but he cannot do anything agains RJ ,Stiles knows he cannot yield RJ .

6-Partrigde was tool of RJ and being used , Partrigde actually killed and death, he just wanted to tell this organization stuff to Lisbon before he gone.

7- RJ will never be revealed as a person ,,but we as audience and Jane will certainly understand who the RJ is, Rj will never be catched up. (Producers tell about his revelation,but revelation will not be showing a person as this is RJ)

8-Patrick Jane will never gets his revenge, Heller will use emotional position of Patrick and his desperation again at final episode 

9-Jane will loose, satanic will win ,but not explicitly ,everyone will feel this but will not see it,like the episodes where Jane was hallucinatiing his daughter as grown up , everyone felt how he desperate about missing his family, Heller will make same kind of emotional ending and Jane cannot beat RJ.

Please note this theory to somewhere and check my previous theories all of them are fulfiling before episdodes broadcasted. 

Please do not give any attention given in serials, like RJ's pyhsical appearance,voice,or other clues, all of them misdirection.Heller has to make serial ostentatious as Patrick Jane, PJ loves showing off ,RJ loves giving lessons and keeps PJ as a child in respect of striking people. PJ can guess killers, but RJ would kill . PJ always search for something, RJ always knows and never struggles. RJ rules, PJ works. So ending have to follow this routine. SEE THE WHOLE ,NOT CARE DETAILS,THIS SERAL NEVER BASED ON DETAILS ,BASED ON THESE TO CHARACTER'S INVISIBLE WORLDS.
