Heller said that RJ is like Waldo, he is always in the backround.......Ron is ALWAYS in the backound.

Ron 
John 
Red Ron
Red John

As the season go on i think we will keep seeing the man we call Red John, if Ron starts to talk more than he has to be RJ. I mean he's got to be walking around in the backround all the time for some reason. i also think that Robert Kirkland works for RJ because of the ending of the last episode!!!
