I'm a bit on the fence when it comes to Hugh. He's had some great moments, helping our established characters come to terms with their issues, and his humor at times is very well written.
But.... as a character himself, he hasn't really developed. Sure, we've seen a new side to him thanks to his relation with Seven, but most of it is a fear of loosing her, even though we have no clue yet where that fear comes from. Usually, for someone to have that kind of fear/jealousy, there's past experience that develops something like that.
Basicly, he's still the same guy as when we first met him. I would like some more development, some more background. Right now, he just is.
