I always thought that Partridge was Red John. Now I am thinking Bob Kirkland (with his twin brother) is Rj because his story fills the blanks.

What is the meaning of "he is mar"? Look closely it. It is kind of "II is mar". It (he) is number two and refers to the twin brothers. Mar means Michael And Robert.

How did RJ know the list of PJ? We know that Rj is also a mentalist. Robert had a great cover. FBI and CBI considered that Kirkland believed PJ might be RJ so they gave information about Jane and his investigation on RJ. Therefore, Kirkland did not need to have a mole in CBI or FBI. Their directors were already his informants without knowing it. We know how mentalist are good at educated guess. Kirkland always watched closely Pj and even knew he was in mental institute even CBI did now know. With all information about Jane and the RJ investigation, a great mentalist like RJ can easily predicts the names PJ suspects.

How are RJ and Visualise connected? Michael had alcohol issue like his father. We also know that Visualise has also members with this kind of problems in their past. (I do not remember the episode but there was a girl with drug addictions and she said Visualise helped her to be clean). I think Michael also became a member and he was at the Red barn. Robert found Michael and how he became drug-addicted there after his alcohol problem. He killed other two members of Visualise and made his brother his disciple. He also hid his brother because he thought Visualise would suspect that Michael killed those members and could hurt Michael. So he made his brother disappear. This is how Bret Stiles knows about RJ. He believes he is Michael who kills people because his killing rituals resembles The Visualise rituals in a twisted way.

What is the meaning of conversation between Jane and Kirkland? When Jane said Robert Kirkland is in the list. He said "interesting. make sense actually but this doesn't help me with my cause, does it?". When Jane said "you are hunting RJ same as me". He also replies "not exactly the same, I am willing to kill seven people to get the job done". He also rejected Jane's demand to work together. He said "we both want our revenge and only one of us is going to get it". He has another agenda. He is not hunting Red John, but RJ himself and he wants to kill other suspects for a reason. That is his revenge. Maybe he hates Bret Stiles because what Visualise did to his brother and Haffner is the one who introduced the visualise to him and Tyger Tyger group is a threat for him or Bertram, McAllister and Smiths are moles in the group led by Red John.

If they are undercover cops inside the group, this makes sense. They are close to reveal the head of the Tyger Tyger group (I mean Kirkland). This why he approached Smith and told him about the group. He is a mentalist and he knew Smith would act with his anger and act against him. When it is revealed that Kirkland is a murderer hunting Red John (smith thinks that way) and might tell about the group to Jane, he feared that that would ruin the operation and he killed Kirkland. However, he did not know that the driver was the man of Kirkland and his gun had blank bullets. He was holding something when he was running. I assume that it was igniter for fake bullet wounds at his back and he swallowed something. I think it was a drug to help him weaken his pulse look him like a dead. In this way, he maybe planted the bomb at Jane house to kill all of them or wants Jane to kill them. That is why he gave tattoo clue to Jane.

Last thing. I am not sure Michael is identical twin of Robert. he said he has a twin brother, not identical twin. Maybe CBI Ron or Brett Partridge is his brother.

Sorry for bad English.
