after a few years of watching piece by piece not much a tv dude, I got hooked on the mentalist last year, this summer got my self season one, and two, so thats all I've seen for episodes in sequence but I'm sure I've seen at least 80% of the episodes, and all my evidence points to Stiles, except the fact that that blind women says the age of him to be much younger than Stiles, maybe it wasn't Red John him self that met that women but one of RJ(Stiles) closer disciples(maybe heffner),
but a good mole for RJ if BS, is in the first season episode "Miss Red" you see a young feller (cop/guard) that tried to stop that girl who made fun of his shirt to get away, that young cop was named "Stiles" hence Brett Stiles way to get inside info on CBI and thats all you get to see of stiles in the first season,
in the second season you finally meant Stiles than you see Red John in the last episode
Stiles is Heffner's leader
Stiles is damn good at manipulating others
and blah I could go on, but from my point of view Stiles is the one who can easiest pull off everything Red John has so far... And get away with it.
