i think its stilles in 03x03 when frye re-appears Patrick go to the house that stilles told him to go, he said "i know more than red john" so i think he has someone inside RJ force, but RJ doesn't realize that one of his close friends its a spy?, i dont think so, so the other posibility is that Stilles is RJ
