I find it ridiculous that some people here think Red John has a fear of birds. How the hell did they come up with this idea? Just because there were pigeons in both episodes? lol

I have read a few theories based on the fact that 6x08 only guest-starres Michael Gaston (Bertram) and Drew Powell (Smith) and therefore one of the two has to be RJ.

But do you really think that if RJ e.g. was Partridge, they'd put Jack Plotnick on this list weeks before the episode airs? They'd give it away if they did.

Also, compare the guest-starrings of 6x08 (three names) to the one of e.g. 6x01 (eleven names) then you will realize that the list is not complete yet and names will still be added.

So IMHO, the two names being known to appear in 6x08 is rather indicating that the two are not RJ. Maybe they are part of the upcoming story. Remember that the show is not over after 6x08 and the writers need to come up with something to keep people interested (which will be hard I guess).

Definately when Heller asked about partridge's death, he had to say Yes he died. He can't say no he just faked it...
Similarly when partridge's character asked about giving voice to redjohn, he can't say Yes...

That does not mean partridge has to be red john..I just want to tell that we can not totally remove partridge from our consideration...

rosalinda harker said rj is just under 6ft tall , patridge is 5 11 the rest are much more off , therefore after all the theorys i read im pretty sure its him

I like making stupid guys without brain laughing! It's Partridge. 

This is a machine translation, sorry.

Brett Partridge is Red John. he fake death. It's a trick.
That it does not kill the Lisbon is misdirection to Jane.
It hid the fake death.
Why not investigating the case of Partridge? Because, there is a truth that can not put out there now.

Future.
Jane revenge.. It is not a crime to kill the dead men. Jane can move on.

The more I ponder this, the more in sure BRETT PARTRIDGE is Red John.

Couple things.

1. Heller said IT WAS IMPORTANT for BP to die in the first episode. WHY ON EARTH would that be remotely important, unless it was to make everyone think he was dead when he wasn't. Again WE NEVER SAW A BODY!! Red John slits throats. BPs throat wasn't slit. Know why? He isn't dead.

2. Described RJ as a "where's Waldo" character. Someone that had been a background guy. This ELIMINATES Ray Haffner, Bret Stiles, and Gale Bertram. Maybe even Kirkland. In fact, probably Kirland.

3. Why would 2 major suspects/characters on a show have the same first name? You never see that!!! Oh I know. Brett with an extra "T" is a junior, as in BRET STILE'S SON. Remember Stiles telling Jane he knows more than Pj or RJ could ever know? Well that's because he used to change lil Brett's diapers when he was a baby. Stiles is 25 years older than Partridge. Having your dad as the head of Visualize would be an excellent way to have limitless resources huh??

4. Someone pointed out that the actor playing BP
said "no" when asked if his voice was ever used in RJ phone calls. Well I'm almost positive there's NO WAY HE COULD ANSWER THAT YES!! That might just give it away don't you think?
