I think she’s using it more to show an air of affectation moreso than as a regional/national accent, trying to portray her "nobility." Same thing with that Count…why was he wearing that sash? I believe those are only worn for celebratory occasions. But, what do I know.
And, as I did last time also, I like Gina’s hair streaks. I think they’re kinda cool. At any rate, they are MUCH more attractive than Kate’s blue one. (Hey, Kate, isn’t it time you gave that horrible thing the heave-ho? You’re Stef’s wife now and don’t need the attention anymore.)
