While it seems like they revealed a lot, they actually didn't reveal much. It seems like a lot to US, because we know how things are "supposed to be." Any variation from the way it's "been done" seems like a tremendous lot of knowledge. To the regular person, this description is minimalistic. To us, it is golden.
Barnabas does need a reason to reject Angelique. One would believe it's for another woman - possibly Josette. But if Barnabas is a [spoiler]"playboy,"[/spoiler] anything is possible. Never would have put that description to Barnabas before so it should make for interesting character development. I do hope that Barnabas falls in love with Josette and, in doing so, [spoiler]gives up his playboy ways,[/spoiler] but I am not sure. If anything, assuming Josette is in this, I don't see her committing suicide for some reason... But, maybe I'm wrong.
