The Scrubs revival’s ending can only really happen one way if the arc of Zach Braff’s Dr. John “JD” Dorian is going to be truly satisfying, but it would also require a reshuffle in the hierarchy of Sacred Heart Hospital. Although John C. McGinley’s Dr. Percival “Perry” Cox served as the second-most senior of all the Doctors in Scrubs for the first eight seasons, he became Chief of Medicine in the sitcom’s penultimate run. Doing so would have implied a perfect ending if JD had stuck around as his second-in-command, but the imminent Scrubs revival can fix the misstep.
