Thomas McAllister was not Red John, he was one of RJ's disciples who was assigned the task by the leader of Blake Association(obviously Red John) to assume character of Red John(something we have seen before, Timothy Carter S03 finale ring any bells).There is no way that Red John who is a character who has been developed and slowly increasing in complexity for the entire mentalist series is suddenly revealed as McAllister in an episode which quality can be compared to the shit from my ass.
On that basis you can say Bruno Heller is just trying to trick us.. again. However he did include something which stuck out for me in S06E08, it must be subtle though because I don't seem to see anyone else picking up on it or thinking much of it.Brett Partridge is the real Red John. You would already know a lot of other strong reasons to believe so accumulated yourself and/or read in many popular theories, on top of them this is what cemented BP being RJ for me, or at least McAllister definitely not being RJ.Notice these things in S06E08 final scene:1. A man standing watching the child playing.2. His stance/posture.3. His resemblance (in build/posture) to Brett Partridge.4. Listen to the audio.Here is the part in the final scene I refer to. (if doesn't near the end of the video at first then skip to about 57sec-1min and watch to the end).http://youtu.be/cfbXiMoeRsc?t=57s
