Here is My husbands theory, those of you who are die hard mentalist fans like my husband and I are, may have noticed that in almost every episode there is a glimpse of an extra named CBI Ron. He has several speaking parts, one liners and what not. Here is our question, Why would a show have a reoccurring extra through out all 4 seasons of The Mentalist. His presence is over powering and once you notice him you will always see glimpses. He is always around when the team is working, and knows the ins and outs of the CBI. The writers want you to suspect all of the obvious people, and maybe they do have a roll to play with Red John. But they are there to keep you eyes away from the real Red John, this CBI Ron! Just you wait and see!
