Guys, surely Red John is Brett Patridge!
I think we don't have to try more because we already know it...
Yeah, I know, you have read too many theories. I am not here to explain with an essay but..
-We never saw the body of Brett Patridge
-Brett Patridge may has a brother
-Red John could easily fool our characters "killing" his self!
Anyway, we will find out at 6.08 "Red John"...
This episode will be AWSOME!
