When Lily is cornered by a group of girls who mock her marriage and dead mother, they physically assault her—she's slapped and held down. A woman later tells Shawn she was slapped too and admits she created the misunderstanding that pushed Lily and Shawn to keep their distance; Shawn coldly says Lily should "return the slap." Pressured by classmates, Lily does. The episode ends with onlookers saying Shawn now regrets it and is falling apart, and Lily is left facing whether to comfort him.
