As it was reported back then:
Now it has been confirmed that a black character will be joining the cast for its next season, who will be named Jack Ross, and that the casting department is currently looking for an actor to play the part.
According to reports, Ross is described as "being 25-30 years and a singer at an exclusive club". Also the Abbey casting department says that whoever is cast for role "must be able to sing and posses a certain "wow" factor."
Hey are you thinking what I'm thinking?
Is he going to be "rolling in the hay" with any of those women on the show? How about that Lady Mary since she's now a widow? She's going to be needing someone for some TLC. I'm just saying. And you know what they say... once you go black....
