Ok just watched the s6 ep6 promo & the first thing I noticed was all suspects but Hafner & stiles are wearing a tie , this isn't surprising for stiles but Hafner why is he not wearing a tie & shirt button undone? , we know about the red tattoo & would assume pj is going to make the suspects remove their shirts , I believe Hafner killed the private investigator with the red tattoo. Ok I remember seeing ray Hafner training in one episode I couldn't find which episode pls leave in comments if you find it. So I'm not exactly sure but I think Hafner is wearing a vest which shows his shoulders so some of you may say he can't possibly be the killer but think about it what kind of idiot would leave such a distinctive tattoo visible & not even make sure the victim is dead. So my best guess is The tattoo is either a complete red herring or ray knows one of the other suspects has this tattoo & is framing them. So back to the Hafner not wearing tie & unbuttoned shirt either he was either in a rush after washing off fake tattoo or is just playin with Jane letting him know he knew what was coming.

I Just have a couple of thoughts after the last episode.

1.) The writers are doing a good job of giving the different suspects their "moments" and now that Haffner has been featured "again" it's making him seem like he is too obvious a choice. But is that another trick?

2.) Does anyone else think Van Pelt is going to be the casualty of Red John? With the announcement of her and "Rigsby" leaving the show it's plausible she gets killed and Rigsby leaves in despair ( I don't think they will kill Rigsby off as he has a child).Or is it another "trick" as we haven't heard anything about Cho going or staying. Maybe he will be the victim and none of them are coming back?

3.) If Haffner is RJ then Grace sarcastically telling him he did a "bang up job" protecting the dead guy probably wasn't a great move. Would this be seen as "insulting" him? Theresa is noticeably always very polite to him even when he is rude.

4.) Does RJ seem more careless and sloppy now? He has to use low end P.I.'s now when he would have had a mole on the inside before? Are we to assume Jane is getting to him and he's flustered?

5.) Ray clapping Jane on the shoulder like RJ again- more misdirection from the writers?

6.) Jane seems awfully cool and detached despite getting closer to Red John. Also, did no one tell him about Kirkland's death? Was he expecting it? Shouldn't he have been involved in the discussions about it?

i am realy dissapointed in Jane ... after girl aproached Cho in gym it was obvious that hi tryed to get close with him... she could see that cho is cop he had a gun ... Jane figure that out ...but??!!////
BUT THIS GIRL LOOKS JUST LIKE CHO's HOOKER GIRLFRIEND .. i instantly knew that this girls is sent by RJ to get close to cho...
Cho is not easy to trick and only with someone look like someone hi love will do the trick.... disapointed really ...

I'm going to discuss a very serious matter , this is possibly the biggest clue Ever to be left about red john.. How many people have three dots as tattoos on there arm? Not many..i can assure you , now lets think this through logically , In the next episode Patrick puts the rest of the suspects in a room and interrogates them , now We all know this happens in episode 6 , we all know we find out who red john is on episode 8. Leaving 2 episodes.. now we know jane has a shot gun to every one of the red john suspects and if the clue is real/Rj is on the list It would just take him episode 6 to figure out who red john is.. honestly it wouldn't take 2 whole episodes , specially when we have the suspects in one room and jane with leverage over them (The shotgun) , now lets look at the possibilities Shall we??

1.The suspects manage to get out before jane ever Interrogates them properly..

2.Red john isn't on the list. (Patrick would have episode 7 and 8 left to figure him out)

3.Bruno heller lied about episode 8 being when we find red john and it is infact this episode... (This could explain why episode 8 only has bertram and smith amongst all suspects , I mean finding out who red john is without actually showing him could be thought of as bad writing on brunos part , .. this episode contains all 5 Suspects as guest stars , i would be thrilled if we figure who he is on this episode but i doubt its true)

So let me Ask you guys , What option do you think is the most plausible? In my humble opinion i think it's Either 2 or 3 , because i don't see any other way why we wouldn't find rj in episode 6  IF he was on the list , I mean hey ill shoot you if you dont take off your shirt.. that seems pretty convincing.. plus PJ is a genius he'll notice some behavioral patterns in the suspects in the room , anyways if you have any more thoughts or possibilities you can add in this i would love to see them , thank you for your time...

PS:- I put up haffners name because if Rj was on the list i guess it would be him (Best fit) 
Because i already stated why we can rule out Smith , bertram , Stiles in a previous post :).
