Well might as post my theory before we find out actually who RJ is. I truly think RJ will either end up being Brett Partridge or Ray Haffner. I will start with Partridge. Wouldn't RJ fake his death so he didn't have to worry about Jane? Well I don't think so. I know people are saying his shirt is different from when he died to when Cho inspected. To me that means nothing. But maybe RJ faked his death to mess with Jane again. Partridge also does seem capable of murder. He seems to fascinated with rJ to be him. I don't think RJ himself would act like that about himself to people. But maybe I'm wrong. Now to Haffner he supposedly dead too right? Well maybe someone over heard Jane tell Lisbon about the tattoo and told Haffner so then he got it removed. He also always calls Lisbon by her first name (Teresa). That's what RJ called her. He also likes Lisbon so that's why he spared her. I thought it was Haffner for a long time. He was my prime suspect even before Jane made the list. But the way he acted towards Lisbon when he found out he was a suspect. I don't think RJ would act like that. So that's when I brought Partridge back in the discussion. I'm not even gonna wasted time talking about the other suspects. If it turns out to be anyone else but one of those two I will be very disappointed especially if its Bertram. Well I have to pick one and I think I'm gonna stick with my gut and say Ray Haffner is Red John.
