CONTAINS SPOILERS!
Just a few more observations about RJ, some of which is from the latest TV Guide article that contains spoilers. After reading the TV Guide it implies RJ is the leader of the Tiger Conspiracy. 
So, I’m pretty sure “he is mar” = “he is mar(ked)” with a tattoo. Baker says that RJ wants to be close to PJ.  Stiles calls it “a form of love” (also notice in Fire and Brimstone who is on either side of Stiles).  How many of our 7 suspects have gone out of their way to be near PJ? Sheriff McAllister wants PJ to call him, “Tom.”  He tells PJ it was his “pleasure to help, anytime.”  He stays around when he wasn’t asked and saves PJ’s life.  Even if he’s afraid of heights (?), he climbs on the roof to do so. 
I’ve mentioned both his and RJ’s being ambidextrous before.  McAllister shoots and shakes hands with his right hand.  RJ shoots and draws the smiley with his right hand.  McAllister helps Jane up with his left hand. RJ drinks tea with his left hand.  They both sometimes wear wedding bands and sometimes don’t. 
Another thing is his voice.  He’s the only one of the 7 whose voice isn’t natural.  I think RJ’s “real” voice is soft, but as sheriff, he projects a gruffer tone.  Of course, those of us familiar with Xander Berkeley know he’s also a voice over artist and has played a variety of characters convincingly.  As I said in a previous post, the actor playing RJ was surprised and flattered, so it stands to reason that the same actor did NOT do the original RJ voiceovers.  ICYMI: Plotnick has previously stated that he always played Partridge as if he were RJ, so I am in doubt if he would be surprised. 
Remember as Dumar Tanner aka Sheriff Ted Hardy lay dying, he uttered, “Red John shhh”….. “sheriff,” perhaps?
