My new theory is about Marcus Pike and the purpose he is serving in the show recently. If what I think is correct, I think that he was sent by Red John the matchmaker to seduce Lisbon so Patrick would be jealous, confess his love, and live peacefully before he start digging again in his memories for answers. However, I believe that PJ is aware of what is happening and knows that RJ will never leave him alone. As for why I think RJ is still alive and doing well is because Bruno Pigeon Heller left us with so many hanging threads.
Here is the press release for the season finale (or the series finale)
