They're just love, aren't they, especially when they're as adorable as mine is! ;)
I've only written Hugo once as a main character (well, erm, given the fact that the next_gen fest is still open that might or might not be a lie, LOL), but I've always enjoyed it. I'd put him in a "supporting" role often enough, but I totally think he's got a potential to be a star! :D
