Guys i think that RJ isn't Einstein.
I think that he just knows Jane for a long time and he knows what steps Jane will make.
Someone hiding in the backround.
Someone who could watch Jane all day.
Someone who have a same ring as RJ.(6x03,When Jane says to Lisbon:"I could marry you off in a minute.",and then he says:"Hi Ron!",Ron has the same ring as RJ in episode  Red Is The New Black.)
Someone who is left handed. (6x03,When Jane says to Lisbon:"I could marry you off in a minute.",and then he says:"Hi Ron!",Ron is holding a file with left hand.)
My bet is on Ron.
If he isn't RJ,then why would Bruno Heller even put him in the every episode of season 6,but just on a moment?
If he isn't RJ,he has some connection with him.
And that weird look Jane is looking at him.Hmmm.
Maybe Jane suspects him,but he doesn't want to tell Lisbon beacuse Lisbon will tell someone and all CBI would knew.Inclouding Ron.


Just my theory.What do you guys think? :)
