I haven't heard anything up to this point, but I think that Jenny will remain a special case in terms of bitchiness.
I'd kinda expect/hope that it's going to be more of a "friends with benefits" story for Ronda where she starts to respect MC and where they have fun together, without necessarily pushing the romance stuff too far. It'll also make her a good partner for threesomes and stuff.
I think the real romance stories are kinda reserved for Eve, Judith and to a lesser degree Roxxy. As odd as it sounds, but as far as I see it, Mia is supposed to become the kinky one, who finally breaks free after she's freed from Helen and who wants to try new things.
