I was thinking about how Bob from The Company has never said what his last name was, or at least none of the characters have noted what his name was. Nathan said he can't remember what it is, and Mohinder just calls him Bob. SO I was thinking that perhaps his last name is important to the story arc, that perhaps he is related to a character we do know the last name of. Thinking about this a bit more, an idea came to me - could he by Sylar's dad? Bob has spoken to Mohinder about Sylar calling him Gabriel Grey, which most people don't anymore. Bob also seems preoccupied with preventing another Sylar from coming into being. I think that somewhere I read we would learn more about Sylar's dad this season, so it could be possible. And Bob kind of looks a little like him, in a way. What do you guys think?
