I wonder...
Lorelei mentioned that PJ and RJ are a lot alike, that they could have been friends.  The only person with whom PJ seems to have a "friendly" relationship with is Stiles. 
Re-watch their scenes together, it's like a tit-for-tat conversation, back-and-forth witty comments. 
Stiles may not fit the clue profiles we've heard from Rosalind et al. , but as we've seen over the seasons, RJ is many.  That ability to bring so many into his circle, drink the perverbial kool-aid, and to have them do his bidding....

I want to follow up on my other posting that Haffner is Red John.  I cant stand this fool.  He is such a sneaky slime bag.  He was just faking being fooled by Jane.  He just sat there all smug during his lecture from Bertram, probably laughing inside at the scam he was pulling.  I also think Haffner is banging Lisbon.  I mean how many times has she gotten laid in 5 seasons?  Once?  He created this whole story about her having great investigative prowess and putting that to use in his PI firm.  The only reason Lisbon solves any cases is because of Jane.  F'ng Haffner is so sleazy.  Not that we all havent conned women into bed but Haffner is just a dirtball.  My hate for his character grows by the minute.  I hate the network for making me wait until Sept. to finally see what I already know.  I am guessing Haffner(REd John) will start to kill off the other members of Janes list one by one.  Haffner obviously has the physical goods to kill at will un-challenged. The bad news is I will have to spend several months waiting for Haffner to be jailed or killed.  I am guessing he will just escape and leave the country.  I FUCKING HATE HAFFNER!

hey everybody !  ..i can prove very easy that is a work by patrick and laureli martins...watch 5x16 there will be blood...somewhere in that episode laureli gets shot in the arm...later in the episode she confronts the guy that tells her that RJ killed her sister miranda...NOW notice her left arm she has a white bandage covering her wound....NOW watch the scene where she " is found dead " notice the bandage in her left arm is gone...judging by her facial expression at least to me  she doen't appear to be dead...if Rj somehow killed her wouln't there be some king of struggle or at the very least some kind of facial expression of pain or something....NOW look at the smiley face there's something odd about the face....it looks fake...for some odd reason they don't show the whole face NOW look at the left eye it doesn't look the same as in other Rj murders..the eyelid is supposed to look like a v upsidedown on the left eye.......NOW HERE'S THE GOOD ONE....look at the video in the season finale when laureli reveals the 7 suspects....LOOK at her left arm...the white bandage covering her wound she got at the 5x16 episode...THAT WAS 7 EPISODES AGO..therefore the video had to be shot after laureli killed the man that told her that RJ killed miranda and before she was found dead at the end of episode 5x16...which explains why patrick got out of there so quicky that way he would have to explain anything about the muerder scene espeacially to lisbon...MAKE YOU OWN CONCLUSION.for some reason i think patrick and laureli have a plan and teresa IS NOT IN ON IT...teresa has been very eager asking patrick about the list in a lot lot of episodes leading to the finale in one particular one even asking jane if she was on the list....what do you guys think?...i'm not acussing teresa.
