For everyone out there that thinks Red John is  'many,' it does not matter. Jane wants the person who killed his wife and daughter, which is only one person. He will probably bring Red John's associates to justice. If Red John consists of multiple people, then I would want to know the one person who killed his family more than the multiple people that make up Red John.

I really love theories on this site,they were very few bad theories abouth who Red John is( Van Pelt,Lisbon,Cho,Rigsby,even Jane himself...those were really bad theories) but now I see a whole bunch of Michael Kirkland theories and I am sorry guys but this one beats all of them...it is the worst theory ever,making Red John someone we have heard about until 6x4...come on,if Michael Kirkland would have turned out  to be Red John it would be the stupidest ending of all time...I am really surprised how many fans this so called theory has because I see a lot of plausible hits on that kind of theories.

     Here is my thoughts , here is my theory....
                     Please Read it...

  After the last episode , it's obvious 3 suspects had a tatoo on their left shoulder and the three are "good" whistlers ; those suspects are Gale Bertram , Reed smith and Sheriff Thomas Mccalister.
 
    We begin with Reed smith the unlikely suspect:
 - He is fat , doesn't fit any descriptions  and didn't appear in 4 first seasons, even if Bruno heller tries to make him suspicious, especially in the last episode but no way, he can't be RJ.
 
    And now Sheiff Thomas Mccalister is a good one , smarter. sometimes he appears alike Jane.

  The last One Gale Bertram he has many friends , he is a showman , Good posture , good speaker , high law enforcement.

   There are two things from the last episode that we should discuss it :
  
   1)  Gale Bertram after the discussion with Jane and Lisbon about closing in on Red John  , he makes a call, he said : " Yes, it's me , i had a very interesting discussion with patrick jane "

     =>  He calls a person who knows him , and who wants to keep informations about RJ. We don't know whom this guy. We should discuss that point.
.  
      2) Why Brett stiles cares when patrick wants to shoot Sheriff Thomas mccalister , and Stiles asks Patrick to see others two whom had the tatoo too :
     
     Did he want to protect Mccalister from shot , because he knew Sheriff is RJ , and patrick will shoot him 100% , because he waits 10 years for that moment.?
     OR
     Did he want to help Patrick , because he knew Mccalister is not Red john  and  Reed or Gale is the real RJ  ?
     OR
     Did he want patrick to know about the sign maybe of the organization "Tyger Tyger" , because Vizualize have some problem with them. ?

    Thanks to you all , don't forget to Share your points of view ...

<b><i>Remaining Mentalist Questions/Mysteries</i></b>

This is not a theory but an attempt to identify all the remaining mysteries which should be cleared up by the writers during the next two episodes or so (or I want my money back...).  Please feel free to add explanations and/or remaining questions in the 'comments'.

<b>1. What "He is man(r)..." written in blood was intended to mean</b>

If you were dying, would you waste time writing "He is" before writing down the name of the killer?  I think not.  Therefore it makes more sense the third word is something like "many" or "married".  Even "He is married" could have been shortened to just "married", so "many" might be the best bet, because it <i>requires</i> "He is" to make sense.

<b>2. Why does Rosalind Harker's descriptions contradict some suspects on the list?</b>

According to Harker's specs, Stiles is too old, Reede is too fat, and Bertram is too tall.  The reason that Jane nevertheless included them in his list of suspects could be that:

- He does not trust her descriptions, because she is deeply in love with RJ.
- RJ is not one person, but 'many'.

<b>3. Why does Bob Kirkland kill Jason Lennon without trying to find RJ's identity?</b>

Bob is seriously searching for RJ's identity, yet he doesn't avail himself of the opportunity to question Lennon about this.  Some people have said that's because he knew it would be a waste of time.  Which sounds pretty thin to me.  Lorelei told Patrick that Lennon was weak and would easily give up the name.  So, Bob just decided THIS guy would refuse to yield the name, but the others on the fake list would yield to torture?  

Another theory presented is that Bob wasn't Bob in this scene, but Michael.  However, Kirkland asked Lennon if he recognized him.  I believe this question could only make sense if it was Bob Kirkland that asked it and not Michael.

<b>4. How did Lorelei know that Red John shook hands with Patrick Jane?</b>

Did she see it herself?  Did Red John tell her? Why would he tell her that? "Hey Lorelei, I shook hands with Patrick Jane, Ha Ha!" - hmm, maybe.

<b>5. How did Patrick Jane whittle his list of handshakes down to 7 suspects?</b>

Never explained, but hopefully it will be.

<b>6. How did Red John know Patrick Jane's list?</b>

Major mystery still.

<b>7. How does Red John's create his distinctive voice?</b>

Is his 'normal' voice fake - or vice-versa?  Does he use a voice-altering microphone? Closest to that voice is probably Partridge.  I don't believe Partridge is still alive however.

<b>8. Why is Red John like Waldo?</b>

One of the writers, maybe even Heller himself, apparently said that Red John is like Waldo.  Waldo is always there in the background somewhere, like CBI agent Ron.  However I am reasonably convinced RJ is one of the suspects on the list.  So which of those guys has been like Waldo all along?  Not one of them, really, according to me.  So I hope the writers will please explain this one satisfactorily.

<b>9. Was Red John visible in the series pilot episode?</b>

One of the writers (Heller?) said something like "Red John was always there from the beginning".

- What is the precise words used the writer used?
- Does this mean Red John the character is already visible in one of the the first episodes?

<b>10. Why did Red John kill Partridge in 06x01: "The Desert Rose"?</b>

Heller said that there was a very good reason why Partridge was killed at this exact point, and this reason would become clear later on.

<b>11. What is the big clue in the final minutes of 06x01: "The Desert Rose"?</b>

Heller said that there is a clue in the last minutes which would be clear in later episodes. Was it because the smiley on Lisbon's face (the eyes) was drawn differently than RJ's normal smilies? Was it all the pigeons in the house, which might have scared Red John away before he killed Lisbon?

<b>12. Who is "Carmen Lee"?</b>

In 06x02: "Black-Winged Redbird" Jane is with Lisbon in her hospital room and a nurse comes in and asks if anybody knows where Mrs Carmen Lee is.One theory is that this migh be a post-hypnotic suggestion from Red John, which makes Jane remember Sophie Miller and eventually leading to him finding her head in her oven.  This could also suggest that Red John planted the clues about his 'fear of heights' (acrophobia) (or fear of insect bites - acorophobia).

<b>13. Does the red-headed lady on a bench feeding pigeons have any significance?</b>

Also in 06x02: "Black-Winged Redbird", while Jane and Lisbon sitting on a park bench, there's a lady on the next bench feeding pigeons.  Some people have speculated that this woman is Partridge in drag.  Or could she have some other significance?

<b>14. Why does nobody ask why it is necessary to shoot a chained (hand and foot) unarmed suspect in the back in order to prevent his shuffling getaway?</b>

I mean, c'mon!

<b>15. What happened at the end of episode 06x06: "Fire & Brimstone"?</b>

Many questions remain from this.  The gunshot, the voice who called "No, wait...", and of course the bomb. Who planted the bomb? Was it Jane, up to some trick?  Or was it Red John, who was forced to detonate it as a diversion to escape?  We will most probably know all this in the next episode.

MAJOR SPOILER... 

it DOESN'T reveal WHO it is but OTHER MAJOR STUFF if it is correct. READ AT OWN RISK....

  Just some Observations...
The first appearence of Gale bertram was in S03E01 , he was behind medias , he acts like a"Showman".According to Patrick Jane ,somewhere in S01E01, Red john is someone showman , artist ,has a good posture.

All connected RJ associate exposed in the previous episode did not have the 3-dot-tattoo, why now ?

BH tried to ruin Mentalist but not to end it ?

On the other hand, why on earth somebody so stupid to expose their identity to others with the easy-to-be-spotted signature ?

Did they swim ?
