I don't know how this kind of mistake might occur , who can leak the most expected episode??? Was there conflict between Heller and with his colleagues??? Or this leak has been made deliberatelly by Heller himself ,likewise "maybe" like this site??? 

Thousands of questions... BUT

The leak episode most likey is the real one, because ;

1- It very fits with extended promo broadcasted previous week
2- This end is indeed schokingly primitive ,essentially that is the matter which make it surprisingly terrific. A simple end against great expectation of audience, power of opposits which Heller was using this method through the serial.
3- Two big lessons:

1st one : " You were smart but arragont, so you could never imagine a person smarter than you "

so being self-possessed is something greater than being smart 

2nd one: Great power is behind being unknown ,mysterious and always behind the throne but no-one can figure or would like to pick you as the one who wanted( I might consider mcalister as rj, but I did not want to pick him, he was not good enough for my own created perspective of RJ)

Apart from those, this power is same for GOD, we believe or think that there is a GOD behind all life , but who is he? There is no list of 7 either; first idea; 

1- Myself(like everybody does in the first place and said Patrick is Redjohn himself)
2- A creator very powerful ,unreachable, invisible and almighty(like RJ) ,but we saw that all his(mcallister) power was originated from his simplicity.

Other than these, there are absolutely too many ridicilous moments in this episode and through all serial , what happened to visualise? How patrick guessed the church and how might him be sure of that bertram was going to reach him? There are of course more complicated of question thousands of ,again BUT: 

We understood that this serial was simple and just for entertaining people,with some background subliminal purposes that was all, we expected too much 

I think this was the original episode and you will watch same on Sunday maybe with some little changes but highly likely with same essence and ending. 

Well done Heller, we enjoyed ,you could make it more greater but who would understand, basic humanity , basic art:)

Here's what really happened...(just a little something for comic relief) :)

Guess with less than 24 hours to go I'll spill the beans.

Red John was introduced in the Pilot, but it's not Brett Partridge.

It's Morgan Tolliver.

Pretty obvious once you realize that Tolliver is the Americanized form of Taliaferro. It's a common name in the south, I can't believe after 6 seasons nobody else picked up on this.

Just Google taliaferro, tolliver or any combination thereof.

Whoever Red John is, I look forward to this site continuing as a 'support group' to help each other answer unanswered questions (you know that will happen), defend the most intricate analysis of RJ should/shouldn't have been, and further speculation about the TT organizations.  In other words, we, too, will take on a life of our own!!

Now won't that be just grand?!?  I can hardly wait......

....meanwhile, let's hope the imminent "Red John" episode matches the high caliber of the series to date!!

(P.S.....I still do not think RJ is one of the seven on that list, and believe Mashburn is the villain)

Heller had to stop there. Season 1 - 3 were Red John (Timothy Carter) died. He was a perfect Red John. It was a perfect final. But "pigeon", "911", "don't kill me Patric" ... too much for me. 

Oh, man. You are making me lose my patience. If you still think the "leaked" is the real one, you didn't learn anything frome 5 seasons of PJ ruses and deceits. You are just dumb.

That it will be disappointing, with a lot of plot holes and absurd twists, this is another matter. This site will be submerged of "So, why did... " , "How is it possible that... ", "It's utterly absurd when.... ", "It was unfair to the viewers to say ... " and so on.

I'm pretty sure that the leaked episode is not the one to be aired on Sunday. I hope it isnt, as quite frankly, I couldnt see any of the writers gaining employment in this bussiness again!

I would think that Jane would want to know how he found out his list of suspects.

I'm sure he would have some other questions for him before he kills him.

I agree with others here, that arguably the single most awaited episode in TV history, would not either reveal the character in a promo, nor allow the 'leak' of it.

There is (as of midnight Saturday 24th Nov.) a link to a youtube full video on the Official Mentalist Facebook page, 44 mins long, strange that they would allow that as I am sure they would be checking what people are saying on there.

I noticed that in the promo, the church scene with Jane and 'Red John', while you see him walking down the aisle, there is no Bertram or candle stick stand on the floor, that is clearly visible in 'the episode'.

I personally think its another great example of the creativity of the writers of this show, thinking way outside the box, and proving that almost anything is possible these days. I for one am very looking forward to what is aired on Sunday, just please don't postpone it another week!
