In the finale, the Kings paid out the premise of the show, completely: that political wife, standing on stage, beside the husband who has besmirched her—we know her, and we know her better than she knows herself. Alicia is a woman who reflexively believes in her own integrity and decency, even as she makes moral compromises. Alicia wants to feel as if she is good, to appear as if she is good, more than she needs to be good. She dried those tears, she adjusted that jacket. In The Good Wife’s last moment, Alicia’s political education ended; alone in that hallway, she revealed herself to be a candidate.
