Just some questions :1, How is it possible for Reede Smith to be on Jane`s list, when we all know that Red John is a slim person (we`ve all seen him in the last episode of season two - it appears to be a tall, slim men). Patrick did see him. He knows that. So why would he put Smith there?
2. Have you noticed that, whenever he watches TV, Jane whatches TIGERS (or other animals) going after their prays and catching them? Is he trying to find out something, or does he just have a guilty pleasure in watching other creatures suffering? And, more important, it appears to have this in common with Red John. I think he`s analyzing the tyger`s behavior in order to discover why did RJ recite the "Tyger" poem.

*Just a thought: I think all the 7 suspects have something in common; one of them is the real RJ, and the other six are related to him somehow. 

And I saved the best for the end: We see a trailer of the second episode of season 2 where Jane says that all this time he has been one step ahead of RJ. My guess? THE LIST thing.
When Kirkland broke into his room and discovered Jane`s work, it was, obviously, a trick carefully orchestrated by Jane. So I think Jane had a sort of game in mind, like "whoever will broke into his roof has something to do with Red John: maybe he is an informant, or maybe he is the actual Red John". There`s the trick, I guess. I think the in Jane`s mind there are less than 7 (now 6 remaining) suspects. My guess? He already has a top three.
