S4, E22: Reeling after the news that J.D. (Zach Braff) and Carla (Judy Reyes) kissed after a night at the bar, Turk (Donald Faison) lets the two of them decided who will take responsibility and have to deal with the silent treatment indefinitely. Dr. Cox (John C. McGinley) reluctantly turns to Elliot (Sarah Chalke) for help getting through to a young, female patient (guest star Sarah Ramos, NBC's "American Dreams"). Meanwhile, Janitor (Neil Flynn) petitions Dr. Kelso (Ken Jenkins) for a new janitor's uniform, only to find his co-workers no longer fear him in his new threads.
