Now, I'm pretty sure it's not going to be as easy as Bruno Heller made it loke in his later interview. He's making us believe that one of the names on that list is going to turn out as Red John. No twist plots.
However, I can't believe him.
First of all, many of the subjects of the list such as McAllister or Reede Smith are just ridiculous. Who wouldn't feel disappointed if, after 5 seasons, a character that has only been shown once or twice, ends up being Red John?
And I'm sure their goal is not, at least willingly, to disappoint the audience.
Some other subjects like Stiles, Bertram, Partridge or even Kirkland might be better choices. They've been dropping "subtile" clues throughout the latest seasons, just to keep us busy and thinking, believing that we're smart enough to figure out who Red John is.
In my opinion, Red John's identity will surely disappoint all of us. We've been waiting for him for too long. However, the writers like having fun and I really think that Heller has played us all by saying that the real name is "on the list".
What if that one's not THE LIST? What if Patrick is really one step ahead of him?
I find the theories about the personality disorder absolutely ridiculous. Taking that into account, I think they'll surprise us next season with another of Jane's tricks, although I'm certain that we're quite close to knowing a lot more about his real identity.
