Im had to rewatch all the episodes and here is an interesting quote from S6 E07.
(Right after Lisbon and Jane questioned Smith about the BA.)
Libson: You believe him ?
Jane: He confessed a murder. Red John would never break like that, not even as an act.
Really interesting if you think the way McAllister acted at S6 E08. And that was 1 episode before S6 E08.
To begin, i believe like alot of people in this site that RJ is somehow alive and we will see a better episode of Jane finding who he is. Why am i so positive you may ask? The reason is that the reveal did not satisfy the fans in any way. Even the last episode had more suspence more tricks by Jane and more action. I just cannot see the big reveal that we are waiting for being given in such a horrible way.
The last episode is going to be RJ related and it is going to be a double episode filled with flashbacks
action and a talk between RJ and PJ. At least that is my guess.
To all of those who accuse PJ of being RJ:
To make my point clear i do not believe there is no possibility of him being RJ as the similarities are alot. But you have to realise how many plot holes that would leave and how many scenes would have to be explained. The questions would be 10x more than the questions that exist now and the end of the series would leave the funs even more frustrated than they are now.
