I can't believe people are still reading into the RJ thing.  Bruno doesn't even respect his fans or the RJ storyline enough to bother to explain anything or tie things up.  Saddest thing is that they never knew who RJ was until that season, which pretty much means that none of the clues ever meant anything and they probably wouldn't hold up now.  It was all a load of rubbish.

On another note, watch Sherlock if you haven't - now there, clues fall into place.
