RED JOHN IS SHERIFF THOMAS MCALLISTER,
Ok. Here I go..
Bob Kirkland and Brett Partridge are goners so that leaves 5 people.
Bertram, Haffner, Smith. In my opinion these 3 aren't RJ, in episode 2 we see Lisbon have a nightmare with these 3 in it and what are they doing? Clearing up a Red John murder, thats their role, they are the ones who cover for Red John, essentially "Getting away with murder" as Kirkland said this episode.
Now we are left with two people: Brett Stiles and Sheriff Thomas McAllister.
Bret Stiles, I think, has a close relation to RJ, we know RJ was a visualize member, and the fact that he knows so much about RJ, he even told Jane where RJ had Kristina. Why didn't RJ kill Stiles for telling Jane where Kristina was? Because Bret was the one who took RJ under his wing and helped him forming a sort of father/son relationship.
Now onto McAllister.
Nick Nordella plays "Young Man" in episode 7(great red dragon) and 8(Red John) (imdb casting: http://www.imdb.com/title/tt3196216/?ref_=nm_flmg_act_2
http://www.imdb.com/title/tt3196212/?ref_=nm_flmg_act_2 )
Here is a clear shot of his face: http://www.imdb.com/media/rm3043796224/nm0634984
Remind you of anyone? A young Sheriff Thomas McAllister, most likely he is going to play young RJ(sheriff) in a visualize farm flashback from 1988.
Another thing, according the script, McAllister is about 45 years old (2008): that
means he was born sometime between 1962-1963; the actor who portrays
him, Xander Berkeley, is older than McAllister (he was born in 1955). This is vital. Why did the directors knock down his age? BECAUSE HE IS RED JOHN. In 1988 he would of been 32-33 if his real age was used but the directors knocked it down so in 1988 he is 25, fitting the Red John was a male under the age of 30 description given by Jane.
