Nothing against the actress - I first saw her ten years ago when she was in LaBute's Medea in London, and she was excellent. But it was funny - Nancy brings her in, and introduces her, not so much as deputy, but as a replacement. I don't know, I don't think it was possible to win here: if they cast another black woman it would have seemed like tokenism; a black man would have seemed sexist; a white woman seems - well. You see my point. So if they were restrained by external factors, I totally understand, but it was never a very racially diverse cast in the first place, and it was sad to lose Nancy. (In fact, we also lost Fitz, and Sam's assistant (I forget her name) and we don't see Edward James Olmos after S1... although we get Jimmy Smits, which helps. And it's nice to have another regular female character, especially one who's driving the military plots most of the time.)
