I watched the last couple of episodes back to back yesterday, really enjoyed doing it that way rather than one at a time, i felt it was a satisfying conclusion to the Red John story, looking forward to the next episode.
I saw an earlier episode, the one where they find the Red John smiley on a barn which used to belong to Visualize, Lisbon asks Haffner if he was ever there, mentioning to him that Haffner would have been 21 at the time, Haffner walks out of the room, i think Haffner is Red John.
Kirkland is too obvious after the hospital killing scene, the twin thing might be something though, maybe he was protecting his twin brother by killing the guy in the hospital.
I watched the episode where Jane is tied to the chair and Red John is seen with their gloves on, it got me thinking again, maybe Red John isn't on that list, maybe Red John is in fact a woman, maybe the scriptwriters have given the audience a red herring with that list, i hope so.
Technically if he has split personalities it isn't him so they could get away with saying that, i hope they don't reveal Red John during this season but the show could survive even after such a reveal, i'm sure they have some directions already mapped out.
Can't wait for the new season, always good to shake things up a little, keeps things fresh, maybe we need a guess who Red John is thread, my money is on Jane having multiple personalities, nah wait, can't be, that would end the show at the reveal part.
