I've been scrolling down through theories and came across several that directly states or implies that Bruno Heller's writing is getting 'shitty' or somewhere along those lines. I find that extremely offensive on his behalf as he was able to keep majority of us intrigued thus far. We don't know who Red John is yet, and I have hope that everything will be explained in the following 2 episodes. Yeah.. just had to state that, I really love the Mentalist and love Bruno Heller for creating it!! 

Anyways, does anyone think there's any significant when O'Laughlin kind of rips the necklace off Van Pelt just before he dies? http://www.youtube.com/watch?v=XYtvydPDWxY @ 2:20. I'm probably reading into things way too much, but I really thought it was bugged or something, so Red John was able to listen in on the team. 

Oh and if Walter Mashburn is in the 'Red John' episode, he'll probably be there to help Jane escape to South America, due to his wealth he'll be able to do that. Just a theory.

So excited for the next few episodes!!
Happy theorizing :)
