Hi all!

I won't tell you who RJ is but I will tell you how you can find him in a simple way without getting involved with the storyline. Finally we'll have our RJ in hand, that's for sure. Let's take another perspective in trying to find out who he might be. In almost all similar scenarios (unknown serial killer), the killer is somehow revealed. It might be a surprise for the audience or just obvious. It doesn't matter. What matters is that the person picked for that role must fit the character which is generated during the run.

You can't expect Kevin Costner to play a cannibal. He has a natural soft face and expressions. Further, he can't make you feel it's alright. What I'm saying is; the actor and the character image drawn must have a harmony/fit like hand and glove. An exact click. Even though most actors and actresses can overcome hard/complicated acts most of the time but when it comes to some psycho-master serial killer, you need someone who can really make that impression. You can play the game of "who could have played this role if it wasn't him?". For instance; try to find an alternative for Jim Carrey in Ace Ventura. Or replace Al Pacino with someone else in The Godfather.

As I can see from the very beginning of the show, the cast-character match goes perfect, precise and intimate. Try to replace Simon Baker for PJ for God's sake! So, the actor to be picked to play RJ can not happen on random selection. Because, if he doesn't get killed by Patrick immediately after being revealed, this means he will have some time in the show. He will talk, do things, etc. Maybe he will get arrested first. We will somehow see him in interaction with other people. But in his true identity. No more hiding...Therefore, whoever he will be, he will have to fill in the bottle of RJ on all aspects. Serial killers after being caught/revealed (as I have seen so far):

a- Act like crazy. Extreme ideas, exaggerated speech, talking nonsense weird stuff
b- Stay calm, joyful and cool until they have no way out but still you can feel his insanity
c- Get absolutely silent like they are not aware of anyone else around them

If you have any other observations, you can add up in your mind. Now the first question is: Which category do you think RJ will fit in? I pick "b". And who would fit into the category "b"? My money is on Partridge or Haffner. Others, even if they try to play that version, there will be a credibility issue.
