I think it’s the forensic guy. He’s small. The person who shot the film makers was small (a woman or a small man). The two people who worked with Red John and later killed where in law enforcement (the deputy sheriff and the secretary). Remember when the secretary was killed Red John cut her with a poison. Someone no one would notice. Red John walk right past the guards and got to the secretary. Someone who could get strange poisons. Someone who knew how to shoot a gun.

ROLL TIDE

First of all, let me say that I am one of you who cannot accept that McAllister is Red John. (I felt better about it when we thought it was Timothy Carter; I could have lived with that.) Furthermore, I am also of the common mind that believes that all that has occurred after the bomb in Jane's house is some sort of comatose dream.

I posted a theory a couple of weeks ago, prior to "My Blue Heaven", where I presented a few reasons that Bret Stiles (among a few others) could be Red John, mostly because of his intellect and acuity, which makes him an ideal nemesis for Patrick Jane. He is, I feel, the only man who could possibly challenge Jane, and play this game with him for so long.

But here is something that bothers me: "Roll Tide"

I've always thought that Kristina Frye was a real psychic. She read the waiter when she and Jane were on their date. Her reading was extremely precise, including the "Roll Tide" rally cry.

Red John said "Roll Tide" to Patrick later in the episode during their meeting. He was really saying "I was there, I heard it, at the restaurant. Just wanted you to know."

So where was he? Was he the waiter? The diner visible in that scene? 

Or is he Kristina Frye?

1) Yes. She is the only other character on the show who possesses the same level of intellect and acuity as Patrick. Aside from Stiles, she is the only other mathematical possibility. They are the only ones that can defeat him with words. There was an unmistakable magnetism between them. Unfortunately, she has only appeared in four episodes, and viewers who have started watching since that episode will not know about her.

2) No. But, if she is a true psychic, she is still possibly involved, depending on what McAllister said at the beginning of his death scene:
Did he say
"I am a psychic" ?
-or-
"I have psychic..." (and the word "powers" or "abilities" was cut off by Jane's hand on his throat?
-or-
"I have a psychic" ?

(I watched the scene over and over, trying to discern the words, but I had so much trouble.)

If the latter is what he said, he could have been referring to Kristina Frye.

Knowing that she is a psychic, her kidnapped her, brainwashed her, and has been using her as a weapon against Jane this entire time. She divined his list for Red John. I'll bet that Jane also knew all along that she was a real psychic, he just couldn't admit it to himself, much less anyone else, because of his past, and the harm that his former life caused to others.

Agree: You think that Kristina Frye IS a psychic, AND that McAllister was referring to her in his death scene OR that she is Red John.

Disagree: You think that she is not a psychic, and has not been invisibly involved at all since her departure from the show.

Please comment!!! I need to discuss this before I can move past it!!!

ROLL TIDE

It is obvious that everything was a hallucination inside Patrick Jane's brain. He has actually been living in a psychiatric hospital from first to last episode.

I think it had to be the waiter, the voices are similar but so was the detective-after watching it twice already! Can you imagine if it were someone on the cbi squad though? I hope this wasnt one of the many tv series that were cancelled this year!

‘Roll Tide,’ the phrase that Kristina used when talking to the waiter in the first of the episode, was the last thing Red John said to Jane. Notice Red John also used present tense when speaking about Kristina. “She’s so fond of you” or something to that effect. RJ’s voice sounded female initially. Plus, when you go back to her previous appearance on the show, she knew entirely too much about Jane’s wife and daugther’s murders.
