I think in finale of Season 6 the Real Red John will be revealed to be Patrick Jane - I think in past he self-hypnotised after killing his evil father Alex Jane because he couldn't handle the guilt, spliting off his bad self - this resulted in a schism in his personality with the guilty half manifesting itself periodically as Red John who has all the skills and knowledge of Patrick Jane. That is how he was aware of Patrick's childhood memorys and aware of the suspect list before Patrick and allways stayed one jump ahead. He has also hypnotised his cohorts not to recognise him when they meet but also subconciously protect him. Also they have carried out some of the killings of Red John to put the authorities off the scent even believing they were Red John such as Sheriff McAllister . I think it's an "in joke" that Simon Baker the actor who plays Patrick has been used as the voice of Red John. - John and Jane Doe = unidentified persons - Doe=DEER - The clues are there - ie Jane playing chess with himself - think about it am I right?
