Another complete and very possible theory on Brett Partridge.

Many clues and reasoning always
brings me back to Partridge.
First I thought that perhaps it He is mar
means that is injured, in the sense that Jared does not know who he
is, but have struggled, as happened with Carter Peak and was
scratched, RJ was forced to flee because someone was coming, but
thought he was dead , but before dying he wrote on the wall. Then he
took away samples of trace or altered after they are collected by
Scientific. RJ had to do before the CBI. Or does it mean Marshall in
the sense of police officer.
If RJ is Partridge knew well how to
eliminate all traces of samples of the hospital, because his
fingerprints and his DNA is in the database, such as those of all
members of the police and army. The elements against Brett are the
following:
- The same voice in 2×23 (the voice is very similar, but maybe isn't the same
also in 4×24, and similar at the voice of Carter). He has a particular way of pronunce some letter and some word, and a particular way of speak some phrases
- Its size and appearance fits on Roy, as described by
Rosalind)
- The clothing of her first appearance resembles that of
Roy Tagliaferro, and the masked man who save Jane in copycats scene
- His necktie and jacket with the word forensics,
it seems that the mysterious figure who follows Rebecca in 2×08
-
Admiration for RJ
- Presence on the two scene of copycats (Wagner and snuff movie directors)
- The
picture of Blake  “A brace of partridge”, linked by a Red John poetry in 2x23, The Tyger
- The character
is completely useless for the purposes of the plot, in the second
appearance; others minors characters have an utility in the storyline
- Although this has a name and a surname instead of
simply called CBI Brett or CSI Brett (unlike CBI Ron, CBI Karl, Security guard Jim or other
agents and characters), appears in the pilot (is also described in the script), but
no one ever mentions him. This is a sign that is important. It's only character very minor that he has a complete name
- In 2x23: the
scene between RJ and Jane (goes away and comes back) is the perfect mirror
image of the previous one between Jane and Brett (for me is very important clue)
- The character
sarcastic and childish (RJ kills for fun and fun and getting offended
easily, as the Joker, even if it’s Jane Moriarty)
- He hates
Jane: perhaps you feel nervous and inadequate in its true form, but
through his role as RJ instead became the charismatic and confident,
like many people with dual identities
- When asked, no “He
interpreted physically RJ?”, But “has lent her voice to RJ
MASKED?” Plotnick said, “I can not say anything to avoid the risk
of ruining the surprise,” he could say or explain: “I only
voiced” or “no, I know nothing” but not said, perhaps because
it had a contractual clause which requires them to remain vague.
-
Has an important position (CSI supervisor, says about: “My guys
have to work”)
- For the same age as (1968) could be both a
friend of Tanner, both of Johnson, O’Laughin and Montero (the
perpetrator of the museum) and Kristina
- Hightower is trapped by
forensics (O’Laughlin killed Montero, but also because he hadn't access to evidence)
-
The CSI agents probably is under him (the strange nervous behavior) also work at
the scene of Timothy Carter
- We know nothing of his true
abilities nor his financial situation (maybe it’s full rich of family or
earn easily with scams and casino)
. The behavior of Partridge does not exclude the fact that it can be
extremely intelligent, but wants to hide appearing stupid or
insignificant (Jane says: “the viewers watch the girl assistant,
while the magician does his tricks,” which could be, in the case of
RJ : look at all the famous actors McDowell, Currie Graham and
Bradley Whitford, and should look Plotnick). However, Partridge is a
person who has the power and capabilities, otherwise it would have
been the supervisor of the CSI, as suggested. All these false trails
laid there for detecting, after almost seemed to shout that he was in
RJ 2×23, the answer to Jack Plotnick (which still does not know when
he will return). the evidence and the arguments make it suspect.



Age: Partridge should actually be older
than Jane (at least the actor is older than one year).

If Heller or other writers in future will says who Red John is a
guest and he don't appear for many time in the show, with his face,
Partridge can be return a very strong suspect. The episode 2x23 screams
to us that Red John is Brett.
He's a ghoul, nervous and seemingly uncharismatic, with a mad face, but even Jim Moriarty of BBC Sherlock has a crazy appearance,  the first time we saw him (in the laboratory) looked like a guy with no power and no leader's character, in fact psychopaths know perfectly disguise, like as is also shown in The Mentalist many times.
Then Brett is right in suspect's list.
