Well, i dont know if anyone noticed this before. But today i was watching a re-run from a past episode when the team had a different boss........ the time when cho injured his back. So anyways the episode involved the CBI following this guy who they thought was going to snap at anytime and kill people. During the investigation Jane and the other boss were observing his characters to see if the suspect was indeed a "killer type". Fast forward the episode, Jane as usual caught the killer and out-witted the boss but at the very end the boss approaches Jane and says while he was observing the suspect he was also observing Jane. He said the qualities he observed showed that Jane was a psychopath and a killer!! This has to be the biggest clue that Jane has a double personality issue!!! 
Also how could he have destroyed that fond memory of his.................he was the only one who knew about that. Anyways there you have it.
