A new road: Abby Lockhart, the part-time OB nurse who cared for Hathaway during "Great Expectations", reports to the ER for her third-year med-student rotation. Hathaway has a hunch that a young patient's health problems come from his mother. Carter and Cleo try to help a sick boy and the unpopular student he fought with. Kerry leaves the ER due to the flu, while Dave Malucci works in spite of it and Benton angles Romano's illness into some help for a young girl who was mauled by a dog.
