I have two points that came to my mind recently

1) I do not understand the whole "Lorelei and Patrick made the video together" thing... if this was the case (=Lorelei wanting to help PJ instead of seeking revenge alone as we saw in the episode)....
WHY WOULDNT SHE TELL PJ WHO RJ IS DIRECTLY??!


2) Bruno Heller just wrote these episodes. I am pretty sure that Heller wrote the main RJ storyline without leaving the job to his other screenwriters, so we should filter the seven suspects against this episode list. I would dare to add that RJ was introduced in one of these episodes!

   Just thought I would share my theory after re-watching Season 3 Episode 3. This episode works around visualize, and at one stage Patrick falls asleep in one of the visualize rooms. When he wakes up he finds a fortune cookie which contains the message "A friend is in danger and needs your help". Although the writers want us to believe that it is about Kristina Frye; what if it is a clue to Patrick's happy memory at the end of season 5. Maybe Patrick was hypnotized and who ever Red John is left this message as a hint to what he would do later on. 
   This then leads me on to why I believe Red John is Bret Stiles. First of, once Bret find out that the killer in this episode is his lawyer Julius, he says "Please tell me you didn't kill that young women". he then presides to slap him. Could Brett have set this all up to get Patrick into visualize and interact with him more. In this episode O'Laughlin also fist appears for the first time and in the interrogation of Julius the lawyer asks him for his cooperation "with the FBI's investigation into visualize and Bret Stiles". As Julius is being moved to the police car a visualize member by the name of Heron shoots and kills Julius. Heron looks to focused and although could be just the adrenaline of shooting someone he could also have been hypnotized by Stiles to kill this man so not to tell anyone who Bret Stiles really is. Patrick and Stiles then have a one to one discussion where Patrick says "Your safe, bravo". In the video sent to Patrick in the last episode of season 5 allegedly by Red John it contained the word "Bravo", could it be a hint by Heller that Red John feels the end is near as it almost was for Bret Stiles in season 3.
   I know Bret doesn't fit the profile described by Rosalind Harker but maybe this is a false clue, after all why leave someone who you were in close contact and can describe you to the authorities without trying to manipulate the investigation.

After I've shown you my theory about Partridge, I want to show us also that one about Raymond Haffner.

Haffner strongly returns to be a candidate as possible Red John.
Telling the truth, I wouldn’t like this choice, but everything’s possible.
Let’s see the reasons that allow us to suspect him. We ‘ve seen him just in two episodes, but we can collect a lot of clues.
He started his career in the FBI Organized Crime Division. Two important arrests using wiretaps and creative
surveillance technique. This could explains his contacts in the FBI and also the way he could get all the informations that he needs.

One of his colleague, the smallish Tork, dealing with Patrick says him ”I heard you used to be in the circus.” Maybe Haffner told Tork about that.

The case his team has worked on (4x02) involved a gym. Haffner declares to know that gym very well and that a lot of bigwigs work out there… so he has important contacts too.

In his office there is a football trophy, so he’s an ex player: just like Todd Johnson and FBI agent Craig O'laughlin. Craig, particulary, knew Amos Van Pelt, Grace’s father. On the episode 4x12 Van Pelt hallucinates and she sees Craig.
He tells her that he’s just a figment of her imagination and that she has to open her eyes all the way, if she want to see the truth of things. Maybe he’s speaking about football: maybe Haffner knew Amos Van Pelt too and he has become friends with O’laughlin, somehow.
Amos Van Pelt was the coach at Burton. O’laughlin has been a professional player (NFL) for a couple of years in Tennessee.

Haffner asks Cho if he thinks Patrick is smarter than him. Then he offers to be a spy for him in return for the job.

Haffner understands immediately that it's Patrick behind the heels trick against Tork.

Shortly after Lisbon made a call to LaRoche about Sally Carter, we can see Van Pelt trying to talk to Haffner, who says he's busy; he looks pretty thoughtful while pouring some tea.
By the way, it seems he is looking for Ron, considering the line of his sight. In that case, Ron could be one of his followers and this could explain all the clues we have collected against him as possible Red John.
Shortly after Sally Carter is found dead, apparently committed suicide, leaving a farewell letter.

Then, coming back to the case, Haffner finds the address book and says to Patrick that he checks on him: “Did you really think that was gonna happen? Like I wasn't watching you every minute?" That's a little creepy.

At the end, Bertram blames Haffner for have been kidded by Patrick and he dismiss him from the assignment. Haffner appears surprised, like he has really fallen in Patrick’s trap. But if Haffner is Red John, then this will be just a big act to looks less clever than he really is.

On the other episode, 5x13, authors try blatantly to make him more suspicious.
But let’s proceed step by step:
first he felicitates Lisbon and he’s sarcastic remembering the work experience with Patrick.
Then he invites Lisbon to have a lunch with him.
During this lunch he starts complimenting Lisbon for keeping under control Patrick at best, whereas he considers Patrick uncontrollable.
He also adds to know a couple thousand people who whould think the same thing.
Then he tries to persuade her to work with him, leaving the CBI and, particulary, Jane.
Later a weird fact happens: Ray nominates Jason Cooper and Lisbon realizes he has being a Visualize’s member since he was young; he says he was a screwed-up kid.
Later we’ll discover that Red John too has been a Visualize’s member in 1988 and that he has worked in a farm. If Hafner was Red John, I think he wouldn’t leave such a evident clue so easly. What for?
Maybe the authors gave us this information to mislead us and to make him more suspicious. But… never say never!
And when Lisbon asks him if he has been in that farm in 1988 his answer is even more suspicious: instead of answering simply “NO”, as anyone who has a spotless conscience would answer, Ray evades the question, answering her “Lisbon, we're still friends, right? Why would you ask me that?”
Maybe he has known Red John and he wants to protect him cause he has become an accomplice. But, one more time, he could be Red John himself.
But we have already learned that when the clues are shown to us so manifestly, they’re probably false… but who knows??
Anyway, the doubts against Haffner are significant. He’s not on the first place among the suspects, but he could be surely on the podium.
My Podium is:
Partridge;
Bertram;
Haffner.
Only missing Bertram's theory; I have one, but it's in Italian. Coming soon... :D
And there is also a theory about McAllister: I found something interesting, but I still think he was a red herring. Anyway, probably I will post something about him too.

I know that there are a
lot of theories about Brett Partridge. What I want to do is not to make another one, but to add to some of them another
aspect that may be relevant. 



Let's start by picking the four episodes that Brett Partridge appeared:

Pilot; Red Sky in the Morning; Red Lacquer Nail
Polish; Red John's Rules.


On the first one, Pilot, you have his first
appearance in the show. It's a Red John copycat, but Brett says it is the real
Red John. 


On the second One, Red
Sky in the Morning, again you have a Red John copycat, and again you see Brett
saying that it is the real one.


On the third episode, Red
Lacquer Nail Polish, you don’t have a Red John case. But he says that it was
accident, while Jane says it was a murder.


On the fourth episode,
Red John’s Rules, you have a Red John case, but again Brett says the opposite,
saying it is a copycat.

 



The question is: Is he supposed
to be wrong all the time? Or is he just playing with Jane? I bet on the second
one. You can’t just say that he doesn’t know Red John well. You just need to
watch again the season 5 finale. He says he’s been working on Red John’s crime
scenes since he begins. And then when the crime scene photographer asks him if
he had killed recently, what did he answer? That it didn’t count, because Lorelei
Martins was an internal issue. So he knows Red John case well. And if you see
the way he says it, it’s like he is answering by himself.

 



But anyway, from all the
suspects, he is the one we know the least. And I believe that this is true for Jane.
But over everything, like his voice, his job, his physical description and what
every other evidence people have about him, what I want to add is this:

 



The three episodes that Brett appeared on a Red John
case (real or copycat) were written by Bruno Heller. And that is not something to ignore. Especially
if you think that in the two copycat cases – that ordinary non-related to Red
John people tried to copycat him – you have Brett Partridge. That’s not
coincidence at all. He went to the two because he knew that they weren’t his
murderers, and he wanted to see Patrick closely.

 



The thing is, although he
is such a small character compared to the other suspects (or at least the
second smaller), he has always been a Bruno Heller itself character. On the
third episode you can see him on a not-Bruno Heller episode, but you don’t see
a Red John case, so it’s ok.

 



I would bet that on the
next episode he shows up, and it’s a Red John episode, the people behind the
writing will be Bruno Heller itself. And that, my friends, would not be a
coincidence.
