Well, someone finally figured out who RJ is. I took 20 minutes to read the theory. Luckily, it felt coherent and readable + there were a lot "Ohhhh yeah!" moments. It was actually Bosco who is, I quote Lisbon, "a damn fly agent," and the info he gives Patrick in season 2 while on his deathbed, which forces Redjohn to kill off Partridge and lure Lisbon. I'm glad he played a role in the end.

Green: If you're happy that you stuck with Partridge and feel rewarded that Brett Partridge turned out to be an alternate identity for Redjohn.

Red: Why oh why... Screw it, I'm going to forget everything I read and carry on making theories its PJ or Mashburn or Haffner. P.S Heller lied to me. :(
