Plot summary
J.D. notices the Janitor cleaning gum off a wall and comments, "that's new"; the Janitor, assuming J.D. had noticed his new watch, thinks he wants a compliment back and comments on J.D.'s newly grown "pubescent Miami Vice beard". J.D. then conducts rounds with his new interns and doesn't like any of them. He thinks Katie is a teacher's pet, Denise has a terrible bedside manner, and Ed is lazy. He welcomes the new Chief of Medicine for Sacred Heart, Dr. Taylor Maddox, and is surprised at how attractive and nice she is.
Later, during another session of rounds, J.D. leaves the interns alone in the ward to watch the patients and gives them specific instructions. When he returns, he finds that they allowed a patient to crash. He vows he is done teaching them and hands them over to Josephine. In the cafeteria, Dr. Cox tells J.D. that he was not too dissimilar from these new interns, and that it is his job to teach. He ends up giving the interns a second chance.
Meanwhile, Dr. Cox is upset that he is once again going to have to be "that guy" who always stands up to the Chief of Medicine. Nevertheless, when he notices that Maddox is keeping a patient in the hospital only because he has incredible insurance, he begins arguing with her.
After Keith calls Katie "Mini Elliot", Elliot obsesses that she is too self-involved. Carla tries to gently give her a reality check, but Elliot fails to see the signs that Keith is still hurt over their breakup. Ted shows her that he is still upset, and she realizes that she has indeed become too self-involved. Privately, she apologizes to Keith for breaking his heart.
After Dr. Maddox sees the Janitor trip up J.D. with his mop, she angrily fires him. When he fails to take her seriously and returns to work the next day, she marches him outside and takes his keys. At the end of the episode a new, friendly janitor introduces himself, to J.D.'s delight.
Dr. Kelso enjoys a muffin at Coffee Bucks and watches the hospital drama unfold. Ted tries to tell him off, but still does not have enough self-confidence to stand up to his hated ex-boss.
