Let me clarify something, because I can't stand some people anymore.
I can't think of anybody else as Red John.
"He's not charming"; "A jerk like that can't be Red John" well, if he's Red John, he has to put a mask when he's with Patrick and in public appearences. You can't deny he's attractive (more than the other suspects anyway) http://tmsimg.com/celebs/v3/AllPhotos/162486/162486_v3_ba.jpg
"He's a bad posture" Not muscular, but not soft either. Just look at this http://1.bp.blogspot.com/_lLsdaCVk3Kk/TAcnBF4_klI/AAAAAAABpbo/QgAShi3Dv7E/s1600/JackPlotnick07.jpg
"He's too young" The actor is 45, he's the one who fits the age window more with Reed Diamond (Ray Haffner).
"He's dead" Every suspect but Smith and Bertram is dead. If there's someone who would fake his death, it's him.
"He's really dead, we saw his body twice". Why didn't they show us the face?
"Because they'd have to pay the actor for nothing" Oh. Tell me, couldn't they show us just Cho checking his face? The camera is on Cho as he verify that he's death, so they don't have to pay Jack Plotnick and we are all sure he's dead. Don't tell me it's useless becuase I don't buy it. Or at least, Lisbon asking Cho to check if it's really him, then Cho texts her saying it's him.
There were loads of ways to show the audience that Partridge is really dead, without paying the great Plotnick, but they didn't, get over it.
Also, Lorelei told Jane that he looks like Red John. Imagine Partridge putting off his geek forensic guy mask. If there's one from the 7 list, that looks like him acting smart, then it's him.
McAllister is helping Jane, he always wanted to help him. He even told Jane he isn't Red John and Jane looked him in the eye, and he realized he was speaking the truth.
It's impossible for RJ to trick Jane, even if he's a good actor, when he's asking the big question directly.
If Bruno Heller said the list is true, and he didn't lie, then Brett Partridge is Red John. I wasn't 100% sure because McAllister was there since the beginning (episode 2 though) but the latest episode told me he isn't red John, and so does the promo. (Congratulations to everybody who thinks it's McAllister because he's in the promo crashing in a window. Really guys, you're amazing)
I didn't want to write too much, but I couldn't help it.
