So we have learned of a tattoo consisting of 3 dots.   I am hoping in a way that all the gentlemen that PJ confronts have the tattoo.  Perhaps as part of the tiger tiger club.  The 3 dots could be part of a paw print?   I just don't want this to be simple and I really don't want RJ to be Haffner.  I feel like there has been so much mystery built around RJ that this revealing of clues and narrowing it down takes away from his (RJ's) character.   I really want to be surprised by the reveal and hope there is something unexpected planned!
