When J.D. decides to use a tape recorder to gather his thoughts, the voice-overs transfer to Elliot, who makes new friends with Molly and gets the courage to tell-off her foil Dr. Cox. However, Eliot soon realizes that Molly is not quite the person she thought she was when her felon boyfriend is admitted to the hospital after stealing a car and crashing it into a telephone pole. Meanwhile, in the world of the newlyweds, Turk is constantly waking up Carla when he goes to bed; and J.D. has concerns that Dr. Cox may have ruined his credibility with the new residents.

J.D. decides he won't start dating again until Elliot does, but doesn't expect the person she starts dating to be his brother Dan, who's still sticking around after the recent death of their father. When J.D. catches them sleeping together in the on-call room, things get a little awkward between the three. Meanwhile, after Turk is diagnosed with Type II Diabetes, he milks every ounce of sympathy out of his friends. Elsewhere, Dr. Cox and Dr. Kelso get fed-up with Molly's perception that everyone is good at heart and seek to prove her wrong.
