第 4 季，第 3 集: J.D. (Zach Braff) has become chief resident and is flaunting his new title and pay check all over the hospital. J.D.'s new sense of pride seems to be especially hurtful to Turk (Donald Faison), who is still a resident and currently being denied more difficult surgeries by his new attending physician. Turk's ego is further hurt when J.D. doubts his abilities as a surgeon. J.D. and Elliot's (Sarah Chalke) relationship has taken a turn for the worse when J.D. is accidentally called the co-Chief Resident and Elliot the Chief Resident. This mix-up lifts Elliot's post break-up spirits. Dr. Cox (John C. McGinley) and Jordan (Christa Miller Lawrence) are having relationship problems as well when they find out that their divorce was not final. Dr. Cox's other annoying woman in his life, Dr. Molly Clark (guest star Heather Graham), faces off with him over a plastic surgery patient.
