In the episode where Hightower is framed as the killer of Todd Johnson, Bertram, in a strange scene with Lisbon and Laroche, quotes a poem by William Blake. (LaRoche was the one who identified it as Blake.) Red John quoted a different poem, "Tyger Tyger" by William Blake, to Jane when he rescued him from being killed by deranged college kids who were killing people Red John- style.  On his deathbead in a hospital burn unit, Todd Johnson's last words were the title of that poem.

This is just a smart hint which can be faked of Bruno Heller as well. But after the list of 7 suspects released i started watching the important episodes regarding RJ again especially paying attention to Gale Bertram. The Season 3 Final is the most interesting episode for this suspect. Imagine Bertram and Olovelein are in the same team. And Bertram knows that something is wrong but he keeps the distance because Pattrick could never reach him. He would never act because of information that was given to him by anyone, anyway he knew something is wrong when Olovelein got a different location of Heitower. I have to admit that i would be kind of perfect roleplay if he really is RJ. I think Brett Partridge could also be RJ - would be a perfect way to prevent being susspecious to Jane. But do you really think Brett would have access to such powerful recources and people while he is doing  his job? And wouldn´t it be kind of boring if a noname like him becomes RJ? Bertram would be much more surprising. Jane maybe knows already that Bertram is RJ, still he can´t proof. This will be the most difficult question for Season 6, how to proof the head of CBI being RJ.

Think about it, and please let me know your thoughts!
