1. My Own Worst Enemy

After Elliot almost kisses J.D. in the on-call room, she begins to question her engagement with Keith.

The episode then focuses on epiphanies by the main characters. Elliot realizes she carried on a meaningless relationship due to her desire to be married; consequently, she calls off the wedding twice. J.D. realizes his tendency to sabotage himself and yearns to avoid it, but fails when he refuses to believe that the Janitor has a girlfriend named Lady. Meanwhile, Turk is challenged with choosing the semi-annual candy bar he is allowed to eat because of his diabetes. He, too, has an epiphany and decides to make a random selection.

Throughout the episode, Dr. Cox, Turk, and Dr. Kelso pull together to diagnose a very charming patient, Joe Hutnik. Cox, upon telling Dr. Beardfacé that if he wants to lose the nickname "Beardface", he has to shave his beard, realizes that his initial diagnosis of Lyme disease was correct, citing Occam's Razor (which J.D. references internally while holding a Razr cell phone). In this case, the patient's tick bite was not discovered because it was under his hair.

J.D. consults Turk about Kim, because he feels he's only with her because she is pregnant with his child. He realizes that's true—but because of the trauma of his parents divorcing, he will stay with Kim even though he's not in love with her.
