This is not a theory but a response to "Stoopkid". After reviewing a lot of theories and comments I can see where you commented about a character at a book signing during mid-season.

The poster "formercop" never said anything about a "book signing". He said a "convention" in Las Vegas.

He is actually correct. Actor Xander Berkeley was at a film convention in Las Vegas, Nevada, last month. It was not a book signing as you called it nor did formercop call it a book signing, either. I was at the event formercop was referring to.

This is how things get twisted up!

Back to what I was saying.

Xander Berkeley was in Vegas, signing photos and talking about his roles as George Mason and Percy Rose.

After the convention, he was at a table signing autographs. He was not charging money for them but donations were recommended and would be given to a charity.

If you selected the photo of him wearing the sheriff uniform from The Mentalist, he would sign it "Xander Berkeley, AKA-Red John"

He was very nice and signed for every last person.

When asked about Red John, he said the show indeed made him the infamous serial killer. He also commented to about 100 people that there would be no more "Red John's".

He then joked that some people wanted Sue Ellen to shoot JR but it did not pan out that way.

Nonehtheless, even though formercop is quite abrasive, you, Stoopkid are very good at twisting peoples words. And not just his either.

I admit, and I will try to avoid rudeness, but you are somewhat infatuated and obsessed. It is a TV show and at the end of the day they all go home rich and famous and you do not.

Enjoy what is left of the series because it will be coming to a close real fast. And as much as I hate to admit it, Red John does not appear to be in the picture (literally).

Yours Truly,
Ms. Deadra Hellenstein

Bruno Heller said Red John is done.
Simon Baker said Red John is done.

"How'd it feel when you got the news you'd been picked to be Red John?
Xander Berkeley: Fantastic! I was stunned and flattered. Earning this little place in pop-culture history was the last thing I ever expected."

Jane is finally out of his depression after like 10 years, they have moved away from that now. The show has a new direction. They are NOT going to bring back depressed Jane again, he will not have to hunt down another Red John. Use your brains people!

As the weeks go by, more and more of you will admit that this is true because nothing's going to happen. Stoopkid will be the only one by the season (or series) finale who will still be a 100% sure that RJ is coming back. Poor guy! :D I guess we should let him enjoy his last 7 weeks when he can still feel a bit important here. :D

Your want/need for answers regarding Red John are the results of bad writing and directing. Sadly for you, Red John is dead. He was revealed quite some time ago.

Condolences to all Red John fans.

There is a rumor that pigeon which defeated Red John later got hired by FBI.

StoopKid (aka Stop! Kid...) : 

Shit, man, you're just saying shit. You think yourself as a writer? You're so full of shit, randomly mubbling about things nobody cares about, for MONTHS you were like "Oh it will be GVP and Rigsby GVP AND RIGSBY GVB AND RIGSBY"...
and now "OK LOL HAIBACH IS NOT THE KILLER LOL THERE IS SOMEONE ELSE" For fuck sake, boy, you're just the worst attention-whore I've ever seen, there are 6 fuckin' episodes left. 
Have you seen the summary of each of them so far?? It's just RANDOM stories with NO CONNECTION between them.
By the way, StoopidKid, if you really cared about your favoriiiiiite shooooow, you should know that next week Lisbon's boyfriend will be introduced.

SEE A PATTERN NOW HERE?? The last episodes will just be FUCKIN' JISBON STORIES UNTIL THE FINALE. That's it. 

You know what will be the last episode?? "RAINBOW world", that's will surely be the title. And the story will be some random shitty investigation just to allow the Jibson romance to finally be over, with Jane and Lisbon kissing and leaving the FBI and living happily ever after.

Bullake Shitsociation, Red John vs. the Scary Pigeon... It's OVER. OVER. OVER. They said it. Numerous times. Patrick Jane said it. Bruno Heller said it. In fact, there is only you who keeps believing about it. You, the "writer". LOL. Blow me, boy.

Who is Red John? That is easy to answer. Red John was Sheriff Macallister. That's right, you already know who it is. The Red John era is done and over. Bruno Heller could not have made it any more clear than he once did. He warned that the identity of Red John would be a disappointment. So of you think it is, some of you do not. Those of you who are disappointed are the people who are looking and hoping for more, pertaining to Red John. Either you miss Red John, you do not like the "new" Mentalist since Red John was killed OR you cannot accept that episode was truly "it".....Red John was revealed, killed and over.

Heller went out of his way to make sure that YOU would know that Macallister WAS indeed Red John.

-You saw the Sheriff actually speak with the Red John voice (yes, I know Baker was the actual voice in the studio)

-Jane said the only way he would be able to confirm Red John's identity is to look him in the eyes and ask him. Which he did!

-After he shot Red John, the scene focused on Jane's face and him muttering "You're Red John"

Jane was convinced Macallister was Red John. Jane killed Red John. That's it!

If you're looking for the end title to have some reference to red or Red John, you're obviously setting yourself up for more disappointment.

The show is not backtracking. It's not going back to anything to do with Red John.

The only thing this show is doing is setting up for it to end, showing that everyone has moved on since the Red John days. Sure, there is plenty of crime to be solved, but anything related to the Blake association, Visualize, Red John is ancient history!

The new Mentalist is whittling the cast down to where they all have moved on!!

The final episode is going to not lead up to a final confrontation with Red John, but with everyone is doing well and moving on with their lives. Not to mention something leading up to Lisbon and Jane getting involved with each other.

Remember, hearts can mean love, too!

My prediction is the finale will be on Jane and Lisbon becoming romantically involved. Not this Red John ship that sailed last November!

Other than being annoyed that it was actually Haibach - I really enjoyed this episode.  There were a few WTF moments but I'm gonna let those slide.  It was just SO MUCH BETTER that the last few weeks that for now I am satisified.

Question though - I don't think they categorically said that Haibach was also behind the other murders - it is just assumed at this point, right?
