I have some thoughts about Bob and Michael Kirkland. Bob may have told Jane an unreal story about his brother. He has reasons. Maybe his twin Michael just disappeared and now Bob suspects him to be Red John. If it is, trying to catch Red John will be the same thing with finding his twin. 
Why did Bob Kirkland ask Jason Lennon "do you know me?". It is because if Jason answers "Yes you are Red John", then Bob will be sure that his brother is Red John. Why did Bob Kirkland catch the people on the fake suspects list and ask them "are you Red John?". Because their answers will explain whether Michael Kirkland is Red John or not.

If Bob suspects that Michael is Red John, does he give this information to Patrick Jane? Of course no. And he didn't give.

Now remember a scene from the last episode. Kirkland and Jane are talking after Kirkland kidnapped Jane. Jane says "What if I just give you one name to start?" and says "Robert Kirkland"

When Kirkland hears this, he doesn't seem to be surprised, but he gets unrestful. Because it shows that Kirkland's twin can be Red John, which he doesn't want to be true. And then look what he says: "...MAKES SENSE ACTUALLY".
Yes it makes sense because he is also suspecting it.

They need Sherlock Holmes to find out RJ's identity :)

Okay, so I agree with those who postulate that Red John isn't any of the 7 on the list. Here's why. We have to assume that at the end of the day, Jane will have bested RJ, outsmarted him. If it turns out that RJ is one of the 7, then Jane gets his man but never really gets that "aha!" moment where he tricks RJ. SO, I think that it will turn out that Jane KNEW that RJ would get his list, one way or the other, so he made up TWO dummy lists. One that he would call his real list, and one that he admits is his dummy list. He wouldn't even tell Lisbon about the real list, because we keep seeing how unreliable she is at keeping secrets. And he know that this would put her life in jeopardy if RJ knew that she knew. Since Jane doesn't believe in ESP, he knows there no way that RJ could read his mind, BUT, he led him to choose the 7 that he wanted him to think are on the list. This would throw him off the fact that Patrick is getting close, and Patrick IS getting close, using RJ's actions in response to the list to further whittle down his actual list. I sure hope that this is the case, none of the remaining suspects are attractive candidates. And, in the end, I think it will be someone else, hopefully, my boy Ellis Mars, who most RJ seekers see only on the surface, missing his hapless brilliance, for reasons pointed out in an earlier post.... Either way, enjoy the final shows!!
