I'm not really sure who Red John is, but I really don't think it's Patrick Jane. Great theory, but if you revisit Red John episodes where PJ interacts with people who knew Red John, the interactions just don't make sense. I like Kristina Frye for Red John - "psychic," supposedly abducted by RJ, the mute routine/PJ hypnosis episode, ect. The Lorelei comment about the first time PJ shook his hand casts doubt on Kristina Frye, but otherwise she may fit. If this were a proper soap opera, her gender wouldn't be a hiccup in the theory - she used to be a man and had gender reassignment surgery!
