Re: A question about Bronn
I'm inclined to agree with Syphon, that he was there as a mercenary. Maybe he was protecting people who were trading with the Wildlings or something like that. I doubt Bronn was ever a member of the Nights Watch or a wildling himself.
I'm thinking that they're setting things up for a "beyond the wall" info dump in season two. When we need to know more about the Wildlings as Jon's storyline plays out, hey, there's Bronn who can conveniently tell us all about them (maybe in idle chat with Tyrion about the time he visited The Wall or something like that).
