Alicia sometimes has a hard time telling black people apart. (Spoilers ahead!) These are the circumstances: she's at Colin Sweeney's weird fetish engagement party to his new future wife (played by Tony-winner Laura Benanti), Gawker posted a picture of Zach with a bong and Eli Gold is freaking out, and she had thirty minutes to get Sweeney to sign a financial disclosure. Then, someone is murdered, and she's trying to remember who was where. At some point, she saw a black man go up the stairs. Was it the victim's boyfriend? That makes sense, they look enough alike, so she says yes.
The detective working the case shows Alicia photos of the victims boyfriend and Sweeney's manservant and asks, "you confused these two men?" One has light brown skin and short hair. The other is bald with a wider nose, different head shape and pointy ears, as well as several shades darker. She says she was distracted. "Well it's a good thing I wasn't there," he replies, "otherwise you would have said I was the killer."
We're not supposed to think Alicia is actually racist. Five seasons of the show have taught us that at her worst she's an ex-house wife whose spent a lot of time in the suburbs with upper middle class white people. Also, boyfriends kill their girlfriends all the time, and it's not like there were going to be a lot of black people at Colin Sweeney's party. You could maybe argue that it was brave of The Good Wife to tackle capital-R Race like this, but we'd say it was a weak attempt.
