I also heard that they will be having a black character next season. He's going to be a singer. Maybe a SECRET (lol) boyfriend for Rose? I don't see him being truly a part of their high class circle any other way, do you all? Maybe if the Lord invests in his talents? Or if Branson wants to start a jazz club...? Haha, obviously I have no idea.
Otherwise, he'll be mostly on the sidelines as a token diversity character which I wouldn't like.
