I've given up on theories now because we just don't know what's happened during the explosion, who got shot, etc..
It's possible that we will find out the real identity of Red John at the very end of the next episode, in the last few seconds..

So enjoy the next episode Mentalist fans, I can't wait!!! I really hope there will be a huge twist and nothing is as it seems!
I will accept anybody as RJ except Reede Smith. 

I had to choose someone to accuse otherwise I can't post it, so for the last time before the next episode, out of respect I choose my all time favourite Red John suspect ever. It might not be him, but I've never given up on him.:)

See you after the next episode aired, have fun!:)
