People i think i might found another clue...
Beside the fact that RJ is most likely a Caucasian male, ~6 feet tall and short hair. There is the 4x13 episode when Rosalind is telling to PJ by phone, that "Roy Tagliaferro" is there with her and you can clearly see RJ's LEFT hand, holding a cup of tea!
On his fingers, there's no marriage ring so "He is Ma..." definitely doesn't mean "he is married". Plus (my opinion), the graciousness of his hand, holding the tea cup, might also suggest that he is English! (and also the "Tyger Tyger" quote).


About Kirkland... i was thinking thees days at another theory: What if Kirkland, like Lorelei, was once an RJ follower and now it's trying to chase him from the "inside"? That could be a reason for the concerns about his cover(?). Please don't send me to hell for this...it is just a thought :)
