I read somewhere on Tumblr that perhaps we have already seen Uncle Rudi, and he was shown to be the guy who opens up Moriarty's cell to see how he has written "Sherlock" all over it.
I have no idea what that was based on, though. (I know Mark has said that "perhaps we have already seen him", but I don't know why someone thinks that guy in particular was Uncle Rudi).
