Macalister is not Red John reason #1748385
(I re-wrote it and added some)

Why on earth would Macalister show up at Patricks house knowing darn tootin well what was going on and submissively let it happen, then set off a bomb that would f him up in the process i assume right ?
Then let Patrick live; fake his own death, just to appear a day later to frame Bertram as himself and kill Patrick?
He coulda just killed everyone Jane's house and handled it there instead of getting surrogates and dragging bodies and all that noise. Makes no logical sense.
Red John could of killed Patrick a kajillion times in six seasons but he didn't. He choses to let patrick know he has this "list", kills Partridge, hires an outsider to un shadily put a bug on Cho's desk, kills her, then goes to a meeting at Janes house and blows it up and only kills Styles and Haffner and lets Patrick live. Then it was finally time to kill Jane ONE DAY later ! Why? "The game is over and i won". Oh, really did you? Just because he walked out with a gun its game over? Lol. Seriously laugh out loud. He coulda pulled out a gun on top of that roof at GVP and Rigsby's wedding !

Also Jane said the scene at his house was theatre, and what ever seemed to be true then the OPPOSITE was true.
Well the opposite of what happened would be that Red John was not even on the list.
Macalister faking his death wasn't the opposite of what happened at all.

And what about the infamous gunshot? A concussion bomb is a grenade. It goes boom! We all heard a gunshot then the house blew up but we missed what happened in between those two events.
Patrick had a flashback at the hospital. His flashback ended right before the gunshot. If it was simple amnesia from the bomb them he woulda forgot a whole lot more than just moments before the boom.
*I think this PROVES that there was mind control and hypnotism going on at his house. By whom? Most likely the real Red John. The guy/girl who made Kristina Freye a mute . The guy who makes his followers love him and die for him with a smile on their faces. Charles Manson'ish in so many ways.
The BA and their members exhibit hardly any similarities to Red John followers. Blake Association is just normal cops and law enforcement that are doing favors in a mafia like way for a boss that they have never met or even know his name. And they don't have crazy eyes like Sheriff Hardy, Bosco's secretary, Rosaline Harker (jk), Todd Johnson, the lady that stole the baby, and the lady in the church. Lorelie Martins is different . She was more than a simple pawn. A high ranking night in shining leather armor.

The reason why Jane seems off in episodes 1-8 is even more proof. Hardly caring that Red John guessed the list, telling Lisbon fatal secrets, not caring that CBI was shut down and just being totally apathetic in every way.
Jane is not a "new man".
He has not gotten over anything or quieted any dark spirits that haunt him. He still sports that wedding ring. He did not just join CBI's and his nemesis, the FBI because he was bored . He needs them. Jane uses people on the regular.
He has a plan, and watching it unfold will be like 10,000 dominoes all falling down one by one .
Check mate .

Macalister is NOT Red John reason #1748385

Well the opposite of what happened would be that Red John was not even on the list and planted the bomb.
Macalister faking his death wasn't the opposite of what happened at all.

When is the next episode??

Like many of you, I'm also very sad and disappointed how it ended. Not just the RJ finale, but all the first 8 episodes were poorly written (at least for me). Like for example, when we learned RJ has some phobia and is a good whistler, then suddenly all the 7 suspects start to whistle and develop phobias that we never heard of from last 5 seasons. That was just incredibly dull and inconsistent. Not to mention they didn't even try to explain how on earth did RJ know 7 suspects before PJ. That came as a huge shocker, even a casual viewer would at least expect an answer to that, it's such a shame. And those 7 suspects came from nowhere, right? I felt like they were more of a product from Heller's head than Jane's which is terrible. First they put someone like Smith and didn't include some of the characters who have made a lot more impact than him (Mashburn, Ardiles, Mars...), and second they completely ignored Rosalind and Red Barn episode because some of the suspects really don't match to what we learned. If anything, they could at least explain why they didn't follow Rosalind's description. And top of all, Kira Tinsley. Omg that was probably the worst thing. Someone who has been breaking the CBI network through all these years falls to a random character and her failed attempt to bug CBI office. How did she even see the tattoo, how did she know about it? Anomaly. And finally, the RJ episode, it wasn't impressive at all. Someone would expect he wouldn't die 10 minutes after we learned who he is. I expected far more. And i forgot to mention, to reduce the 7 suspects to 1, they just killed every other, haha, terrible.

I give only 1 % chance real RJ is still alive. Only way to even try to explain this  horrible mess is it was maybe orchestrated by real RJ, to deceive everyone. But, i will not hope on that, don't wanna be disappointed twice.

If anything will pop out, probably it's gonna be some close RJ friend. From CBI maybe? Like Ron or a wild card Cho (unlike Grace and Rigsby, he is the only one undeveloped) or someone else, doesn't matter. Then we might learn how at least RJ knew 7 names.

Maybe he's RJ maybe he's not, but watching an old episode made me think.

The episode where Jane goes on the one "You Got Served" show or w.e it's called, where he tries to catch Henry Dahl's killer.

Craig (who we figure out is one of RJ's many accomplices) is talking to Rigsby and Cho, then Van Pelt asks him "Where do you wanna go for dinner". He says "Napa".

Napa, Napa, Napa. We know Thomas "Red John" McAllister is the sheriff in Napa. Maybe he was there for a meeting with him?

Note this can mean nothing and could be interesting, but this is probably the only episode where Craig and Van Pelt say they are going on a date, and by surprise its where "Red John" lives? Maybe Van Pelt is with RJ and went there knowing they would meet him?

Yay or Nay?

I'm so glad to see that people here are finally starting to get it. The RJ case is closed and there's no point trying to make up theories anymore.
This series used to be the best but they all messed it up in season 6 and now it's time for us to move on and discover new shows that we will be just as passionate about.
5-6 years is a long time, so well done Mentalist. It didn't end the way we wanted but true fans will still keep this show in their hearts forever. The show must go on! (just not this one.:P)

At the visualize farm we know from "Red Barn",  two red headed women kill a member of Visualize.  According to the killer's story, her mother was being attacked.  The daughter killed a man, in self defense.  Mysteriously another murder was occuring; in fact, two murders were supposedly happening.  
I suspect that there were no other murders happening.  McAllister was called in as a friend by the mother of the shooter.  She needed police assistance.  She didn't want her daughter to go to jail, so she gets McAllister to help her out.  McAllister might be her ex-boyfriend or the girl's father.

McAllister shows up and gets rid of any witnesses.  However, one witness escapes (mysteriously).  Only people familiar with the farm knew about the underground room.  The mother knew about the room, and we know she did.  In the story, the daughter reveals that her mother knew about the room - since she had been out there (before).  

In order to track down this alleged witness, McAllister left an ensign.  He draws a smiley face in blood to make a trademark.  He plans on getting some publicity, so he can intercept the witness.  If the story got to the press, the surviving witness could come forward.  When he or she came forward, McAllister would be able to intercept the witness.  He would use his police badge to get information from other officers.

Since the attempt was unsuccessful, he needed to murder again.  He planned on luring out that witness, because he didn't want to be blackmailed nor arrested.  Truthfully, Visualize could have been blackmailing McAllister, but it is unlikely.  More murders meant the surviving witness could come forward, and he or she could solve the case.  More murders were a way for Red John/McAlister to try to get info about the surviving witness to his murders.

The reason for the victims being red headed is simple.  The girl who did the original murder was red headed, and her mother was red headed (or are red headed).  McAllister wanted to stimulate the witnesses memory of the events from that night, so they would come forward with his or her testimony - which could put McAllister in prison.

If Mcallister did get backmailed, the blake association could be a group of police officers being blackmailed.  McAllister could be a "drop", in the bucket.  However, there aren't a lot of criminal law enforcement, even though the B A  is a large organization.  It seems unlikely that many police would be a part of it, but they could be bribed.  Timothy Carter had a "slave" locked up, in his basement.  If she was pimped out to politicians, judges, police, or FBI , those "johns" could be blackmailed.  Red John might be a name chosen for being one of many "johns".
