I wouldn't guess it would be that much of a crisis to nearly anybody.
Ma Whittaker's lament is going to amount to, "Sigh. Well, damnit, I was hopin' at least one of 'em would have grandkids, but it looks like that ain't happening...." I know bigotry is a stereotype for Georgia, but that's all it is. Faye seems to have arrived without a bunch of attitudes about gays, blacks, etc, and her sister Amanda, who is actually in an interracial lesbian relationship, had Ma Whittaker upset because of *financial* irresponsibility, not bigotry. So it looks like neither of them got that kind of intolerance at home.
Angus and Faye weren't waiting for each other anyway as far as I recall. If he's at all upset, he's going to blame himself for walking away, not Bubbles for being there for Faye when he wasn't. It's also likely that he's dating someone else now, and afraid that Faye is going to be upset with him. Cue comedy when respective partners both roll their eyes.
Sven, on the third hand, I can see getting smacked a little bit when he asks a crude question about whether Faye & Bubbles are into threesomes.
