S5, E21: The Staff Rallies Around a Despondent Dr. Cox -- After a decision results in the death of three of his patients, a despondent Dr. Cox (John C. McGinley) shirks his duties and turns to drinking. Shocked, the staff does their best to cover for him at the hospital while each takes a turn trying to convince him how inspiring he is. Meanwhile, Turk (Donald Faison) is excited to start his new rotation with orthopedic surgery, but is put off by his attending doctor’s touchy-feely methods. So, J.D. (Zach Braff) and the Janitor (Neil Flynn) attempt to help Tuck find ways to bond with his new supervisor. Sarah Chalke, Judy Reyes and Ken Jenkins also guest star.
