Come on, people - if there's any logic in this show the Red John could be only one person - Bret Stiles and I will prove it to you easily.

Let's try to profile the Red John a little. What is he like? Apparently he is an influential guy. Which means - money. But that's not all. The people are ready to kill for him. And that's not nearly all. The people die for him with a smile. He teaches his followers how to face and get rid of their fears. He shows his followers how to be in peace with themselves (or at least the followers believe so). Followers ... FOLLOWERS !!! What kind of guy has followers, ready to die for him? Do  you think that could be the chief of CBI? Do you think that could be some sherriff? If you think so ... well ... think again ... or .... maybe, ... exactly, that's right - A LEADER OF A CULT. There's only one in this show. If it was a reality, FBI would've done that profiling in a minute and Bret Stiles would be on their short list a long ago.

Ok, you'll say, but the sheriff admitted that he is the Red John and that's why he is dead. Is it possible that he impersonated the Red John in order to divert the attention? Well ... it happened before. Remember the end of the season 3?

Well, but Bret Stiles died in the explosion? Did he, really? Who knows ... 

Like I said - this is the only logical Red John. And considering the fact that we're still in the middle of the season I still haven't lost hope that it would appear that I'm right. And not because I wanna be right, not because of my ego, but for the sake of the show. If the sheriff really is the Red John it seems lame and far fetched. However ... there is only one way to find out ...
