In "The Longer You Stay", Chen and Malucci attempt to treat a patient without compiling a complete medical history and fail to recognize his illness as Marfan syndrome, which Carter correctly diagnoses immediately after seeing the patient's chest X-ray, but too late to do anything. Malucci mistakenly assumes the patient is a drug user, and the procedure he and Chen perform proves to be fatal. Kerry Weaver, the on-duty attending physician during this incident, could not be reached because she had gone across the street to Doc Magoo’s and left her pager in the restroom. When she returns and learns of Chen and Malucci's procedure, which required her authorization to be performed, she became enraged and tells Malucci that "in a perfect world, Dr. Malucci, I would never subject any patients to your care." Chen is ultimately forced to resign over the incident, though she later appeals the decision and returns.
