Ephram regrets promising Nina that he would watch over Hannah at school, especially when her constant presence interferes with his time alone with Amy. Amy befriends Hannah out of a sense of charity, but soon finds Hannah so refreshing that a real friendship develops. Meanwhile, Andy tries to ignore the tension between Dr. Abbott and Edna, but his attitude forces Edna to quit and go to work for Dr. Hartman. Andy treats a 13-year-old patient (guest-star Carter Jenkins) whose mysterious injuries cause Andy to suspect the boy's mother (guest-star Elizabeth Mitchell) of abuse.
