This is what we know so far as this season and the reason why Kevin Corrigan has been introduced, and is a possible suspect to be RJ. If he isn't I think he is definitely working with him. Kevin Corrigan is playing a character called Robert Kirkland and is the man in the limo at the end of Red Dawn. He is going to be in at least Episodes 7 and 8 and probably more. It is interesting to note that in episode 8 Jane goes to Visualize to see Bret Stiles to help ferret out Lorelei....so we shall see how Corrigan aka Strickland plays out...I am sure Visualize is somehow connected..I don't believe Stiles is RJ...but maybe a former leader of the cult that was usurped by Stiles?

In my opinion with this relevation it makes no sense that RJ is any of the Lisbon's team. I mean why involve the FBI when Jane can be watched close up by the actual team members. So Alexa Shultz,  Strickland and who ever else is under that particular team of the FBI would seem suspect.  

I really think that the creator of the mentalist series doesn't even know who red john is .

In my opinion, RJ was revealed in the fifth episode of the fifth season, this is the man in the car with Alexa Schultz! It's obvious

It is Patricks father.

I though it was given away on last Sunday' episode. At the end of the episode an FBI agent, Alexa Shultz, calls Minelli from a limo. After she hangs up, there is a person sitting right across here who thanks here for making the call. Isn't it obvious?

I believe Red John is a group of people.  That makes them more illusive.  There of course is a leader and that leader is in question, but many are in this group.  this makes sense to me because the people that help "Red John" are often killers or people hoping to rise in power.  Some of the greatest movies and television shows are based on secret groups willing to do evil things to rise to power.

Just a guess, but this seems the only thing that makes all of it fit.  I do not think it is Jane.  Nor kistina frye or grace.  

Thanks and good hunting us.

I have been watching all the episodes of this great serie and i believe Red John have never showed himself to the public "yet"
All the caracters we have seen untill now are just people working on catching RJ or working on helping RJ but clearly RJ himself have not been on the show yet.

I think that Miss Schultz of the FBI and that guy in the limo are just the high officers helping RJ, dont forget patrick mentioned this already a few times.... remember that RJ's only chance of not getting cought is help from the inside.

The thing is..... this whole serie is not about Patrick Jane but about Red John ( think about it ) the most exiting episodes are the ones with RJ in it, if the writers of the serie put out RJ face now it will defenitly mean the end of the serie.
I just think the guy in the last episode  Wth Miss Schultz in the limo is gonna shake up some things but cannot be RJ.
