Staking Claim

S3, E3: Ephram regrets promising Nina that he would watch over Hannah (recurring guest star SARAH DREW) at school, especially when Hannah's constant presence interferes with his time alone with Amy. Amy befriends Hannah out of pity, but she soon finds Hannah so refreshing that a real friendship develops. Meanwhile, Dr. Brown tries to ignore the tension between Dr. Abbott and Edna, but Dr. Abbott's attitude forces Edna to quit and go to work for rival doctor Jake (recurring guest star SCOTT WOLF). Dr. Brown treats a 13-year-old patient whose mysterious injuries cause the family physician to suspect the boy's mother, Sara Beck (ELIZABETH MITCHELL), of abuse.
