Watching over 4 seasons of "The mentalist" has provided us with a quit handful understanding of Bruno Heller's strategies.He's an Expert at distracting us from the truth lying in front of our eyes; so according to his methods of scripting I think he's going to surprise us as he always does.but considering PJ , BP or BS as Red John isn't much of a surpise cause we've all thought about it. I believe RJ is someone we see each episode but can't think of him(if he's a man) as RJ.someone like Cho or Gale Bertram.
