S5·E1 Day for Knight

Third-year med student Lucy Knight reports to the ER for the first day of her rotation. Greene takes a teacherly interest in her, helping her get acquainted, but she gets off to a bad start with the irritable Carter when she speaks insensitively, and without Carter present, with a patient's wife about her husband's very serious condition. The rest of the day finds her comforting a woman who has suffered a miscarriage, getting locked out on the roof, having Carol bail her out on a simple procedure, and trying to figure out Kerry Weaver's "Tour on Tape."
