Lorelai Martin's sister was killed by Red John. Now, I question the integrity of Lorelai's testimony that Red JOhn has shaken Jane's hand. She did say that they would be 'good friends'. I understand her to have been respectful of Patrick Jane. If she worships Red John, she must think highly of Jane to think that those two could be 'good friends'. She said it, but she says that Red John thinks it. I believe she thought of it only because she liked Jane. Now, this is a clue to Red John's identity.
Jane is a leader, and Red John is a leader. Two leaders could 'bump' heads on issues. Jane is seen as independant, and Red John needs people to follow. Red John's freinds are afraid of him. Jane is unafraid. It is likely that the two would never be 'good friends'. In my opinion, Lorelai exposed the fact that Red John has an inferiority complex. I believe he lives in somebody's shadow. His success is underscored by the person he assists. I believe Red John could be Brett Stiles' assistant. Red John is looking for a way to move on, despite his feeling inferior to Brett Stiles. Plus, the murders that made Brett Stiles popular could have been orchestrated by Red John. Brett Stiles could have been framed for those murders, so the business gets taken over by the assistant. Red John might have used his contacts (in the FBI) to setup Brett Stiles for murder(s). It would explain how Brett Stiles could know about Kristina Frye's whereabouts.
I believe that Hafner was quitting his job to avoid confrontation with Tyger, Tyger. His new job is an honest man's attempt at dealing with hiding. If you were an FBI agent and you hid from a perp, you would feel depressed. Hafneroffers Lisbon a job, because he just wants to offer Lisbon the same comfort he is experienceing; while hiding. He fears Red John, and he wants to protect Lisbon. He knows that Red John has friends in the CBI. Hafner wants to avoid a "run-in" with Red John's friends, in the CBI. Hafner's "gut" is telling him that Tyger, Tyger is watching him. He wanted to look respectable, while running & hiding. He is keeping his composure. "Visualize" is helping him cope. I think about the type of person Red John must be and Hafner is far from it. However, his new boss looks more the part. Red John just might turn out to be Brett Stile's assistant.
