Wtf guys you say that only partrige and bertram are on imdb list i just viewed the cast list so either im blind or you are dumb but 

I CANT SEE neiter patrick jane, or lisbon or anyone else from the team on the list. so how can you even say that one of partrige and bertram is red john the description clearly says that Jane meets RJ face to face,  so Baker must be in the episode.

Or else i have a theory that might be possible the Jane RJ contact shown in episode 8 will be from their past, maybe when they met the first time as still teenagers or something like that, Jane will be dreaming or just thinking about the past and the whole episode will be shown like that. we will know who is rj at the end of 8 and jane will know who is rj by the and of 8 but the actual contact in the present time wont exist not yet in episode 8.

my theroy, sorry for bad english hope you understood it. byebye
