I've just watched the season finale episode and I don't think any of the suspects on the list Patrick's got is Red John. This occured to me when Lorelai said "you think you are pretty damn clever, but you are not". I think Red John might be someone Patrick met way before his family was murdered maybe when he was young... However, I really think is that Red John's got a lot of "accomplices" or "friends" and some of them are in Patrick's list. I think we'll be completely surprised when Bruno finally reveals Red John in season 6. I can't wait!!!!!
