The Good Wife question

I missed part of last season – why does the black guy hate Cary so much?

Wait, which black guy? Do you mean his supervisor in the state’s attorney’s office as in yesterday’s episode? I get the impression that it was romantic jealousy as he’s also interested in the female attorney who said that she was resigning within a week.

Yeah, that’s the one.

Is that all it was? I had the impression there might be some back story there – maybe not.
