** CONTAINS SPOILERS **
The episode overall is very good. But Stephanie March absolutely KILLS me in the end when she has the husband on the stand.
Through the course of questioning, she shows him that he was, in fact, that father of his wife's child, rather than the other man she'd been sleeping with and for whom she planned to leave him.
I love her delivery of the last lines of the cross-examination. When she asked, "Did he cry?" her voice dropped to just the right level. It's just an amazing bit of acting from March. I always love when there's just one line in an episode that totally stands out. That line, for me, has always been the main thing I remember about this episode.
