To all of you morons out there convinced that Partridge is RJ - do you
really think that someone would create a show in which he would allow
you to solve the main mystery by simply comparing voices ?! And not just
that - but to give you only one guy who has a creepy voice, like that
one of RJ ?! Do you really think that there are only a few of you whose
first suspect was Partridge ?! Are you really that stupid ?! Difference
is, we ruled him out because it would be a lame solution to the show
that is totally opposite of lame. However, he is connected to RJ, as are
Bertram, Kristina and GVP.

Further, the writing "He is ma" was
not meant to be he is Mars or Mashburn, but he is many. Those names
would mean nothing to Jane and the CBI since they meet those two way
later. And as the story develops, we find out that RJ has a net of
disciples, helping him in any way possible, including killing. And can't
you initiate your brain cells just a little bit, and use the mirror
when Lisbon is getting nearer to the bathroom to figure out where the
smiley is, and also realize that it is not the first thing you see at
the scene, because you block that left wall when you open the door ?!
And at the end of that episode, when Jane answers the phone, does the
voice on the other side sound anything like RJ's ? Of course not.

Also,
about shaking hands - it doesn't mean you should re-watch all the
episodes and lookout for the hand-shaking scenes. That wasn't supposed
to be taken literally. In Jane's book, there's a name of Dr Morning, a
"dead" guy. Did you see him shaking hands with Jane ? NO ! That means
Jane met him in his pre-CBI days. He also didn't shake hands with BP,
and yet his name is first on the list. Besides us ruling him out because
that would make the writing of the show bad and transparent, we ruled
him out because of his age and all of the other descriptions of RJ which
he doesn't match. But, Jane himself didn't rule him out so that makes
Partridge a legit suspect. And stop mentioning that scene in which Jane
and Kirkland shake hands. It happened recently, meaning they didn't have
enough time to become either friends or enemies after that. He is not RJ.

If it turns out that BP is ... that would make The Mentalist a laughing stock. So it is safe to say that someone else is RJ.
