Red John is very powerful, has a lot of disciples.Also we know that is a tall character.And in some way has some sort of style, like PJ.
Of course is absolutley smart.I think B.H is playing with us, showin a character in the shadows that is the mos likely to be RedJohn in the "Red dawn" episode ending.
And showing him again in the last episode, makes me think that maybe we are finally meeting RedJohn himself.
It is tall, intelligent, in a position of power(NSA), he has about the same age as PJ.He is kind of threatening, but not disturbing crazy.About the voice we could say that is like the other suspects, but he has something extra, call it the X factor.
What can I say?: ROBERT KIRKLAND IS RED JOHN.
Untill we watch him murder someone (most likely from CBI) this will be a theory.
