Like some of the theories on here say, I really want RJ and the "Tyger, Tyger" group to be two separate things. Also, I want RJ to be against the "Tyger, Tyger". This would explain the death of Partridge, is RJ slowly taking out the members of the group? Lets hope so. For some reason I want RJ to be a kind of a sympathetic villain, I want him to help PJ take the "Tyger, Tyger" group down. As for who RJ is, Haffner seems the obvious choice, firstly he fits all the physical description, then there is his relationship with Lisbon. Finally, what interests me is that he doesn't work for the law enforcement anymore, instead he works privately, is this a clue? ("Tyger, Tyger" has memebers of the law enforcement).
