Ron casually strolls around CBI, but no one can really say what he is doing. I would suggest he was once a carnival freak with Jane and became Red John because of jealousy. Ron is all places at all times, and never has to inject himself into the drama or showmanship of CBI investigations. Clearly, Ron is Satan. Ron is Red John.
Has no one suggested that Ron likes to make his job easier? How else could Ron make his job easier than to get Patrick Jane to work for CBI. Is Ron not legend? Is he not wise? Is he not always smiling?
