I think that RJ is Oscar Cordero, the guy who brought papers on Bob Kirkland murder to Rigsby. I know that he isn't a major character in the whole series, moreover I think this is the first time he showed up (let someone correct me if I'm wrong).
From the beginning of the season 6 I never bought the story with 7 suspects. I know that there are a lot you guys who believe that Red John has to be on the Jane's list (list he told to his CBI partners) because Bruno Heller officially confirmed it. That's OK, but honestly if that's true, I think the series will turn out as one of the biggest flops in recent years. Why would you simply tell your audience after 5 seasons who the "real" RJ suspects are when you haven't told them almost anything in last few years. A wise man, good director is never going to do that, now I only hope Bruno Heller is a wise man.
Why do I think Red John is Oscar Cordero? I don't know. I got a weird feeling when he showed up. He is so neutral. He matches RJ's description, short hair, average height, kinda normal voice, not muscular but he doesn't seem physically week. Actually, when the idea of Red John being him crossed my mind was when he said to Rigsby that maybe one day he will do favour for him. That's what RJ wants, other people to follow him, to obey him, to do favours from him. By the way, on IMDB it says that he features in "The Great Red Dragon" and "Red John" so he's not a character of zero significance. The only thing that doesn't match is his age, he looks like he's barely 30.
I don't know guys. That's just my guess I wanted to share with you. Most probably I'm wrong, but I wanted to contribute to this site before it shuts down, before saga is over.
