S6, E10: What a difference a month makes -- J.D. falls for a sexy new physical therapist but because of his unfortunate circumstances he finds it difficult to ask her out. Meanwhile, Turk breaks his arm and Dr. Kelso sends him back to residency where, with the help of Dr. Cox, he realizes that he knows less about actual medicine than he thought he did. Elsewhere, Eliot invites Keith to move in with her, but isn't quite ready to compromise her house rules. All the while Carla provides each of the doctors with guidance while they get over their fear, ignorance and stubbornness.
