Don't know about you guys, but I'm actually looking more forward to "My Blue Heaven" (The episode after "Red John") to see how PJ copes with what has transpired. And especially because Simon Baker directs that episode and I thought that "Blinking Red Light" (Another directed by him) was perhaps the best episode of The Mentalist because of its symbolism and script - "That kind of duplicity, leading a double life. I don’t know
how you do that.” – James Panzer to Patrick Jane.

My view on who RJ was worked out by thinking outside the show. SPOILERS...

Someones twitter feed has the phrase "Truth be told" said twice and its Ray Haffner. And we know the RJ actor stated "Truth be told, I thought I was a red herring".

I am upset at this but hey I'm sure Brett Partidge will be unmasked as the forensic guy who removed RJ evidence. So we were kinda right haha.
