We can all agree that the reason that Angus hangs around is because of Faye right? Frankly, he doesn't seem like that bad of a person as some people make him out to be. "Boundries" be damned I say. He likes Faye, and she has this whole aggressive repulsion thing going on with the people in her life. There's something to be said about matching wits with a character, a la Shakespeare's "Much Ado About Nothing."
I'm not pretending to know the whole character development that Jeph has in mind, but seriously who's never heard the idea that opposites attract. I mean really, Angus gets paid to lose arguments. Anytime he could get to try and win one or at least defend a position righteously seems like something he might enjoy thoroughly. Even if Faye really doesn't like him, it's not like he knows that.
The only inkling we could have is the fact that she just got out of a bad relationship, sort of, and frankly there are way too many unknowns with Faye's personality to judge whether she is or isn't interested.
Anyway, I know that I'm a n00b here in the forum, but I've kinda got this OCD thing with stories that I find interesting. I read the whole series in one night basically non-stop and this opinion is the result of it. Of course it could be the fact that I've been up for 24 hours straight with the help of adderall, but whatever.
