In the last episode there will be 7 suspects.
All of them will be shown. One is RJ. (I think he is Brett Partridge)

But whatever. Everytime PJ gets closer, RJ is one step ahead. PJ uses PJ friends to do it.
This time, PJ is working solo. No, he is not. He is always talking to Lisbon. Maybe she will be the secret move, or maybe she will spoil everything. She is in direct contact with Gabe Mancini, from FBI, on those poker games. PJ is using her to mislead RJ, but who knows what she can say without thinking?

I think we will she RJ face, I think someone will die to protect PJ.
RJ will lose and run, and, on season 6, RJ will use everything he have to not be catch.
