The outbreak of a sexually transmitted disease affects several members of the hospital staff; Izzie and Cristina worry about a patient whose wife and daughter are at odds over his care.

When Robin must leave in the middle of their first date, Ted can hardly wait to see her again, and his eagerness threatens to scare her away.

A man accused of murdering his wife realizes he's been given a second chance at correcting past mistakes.

J.D. (Zach Braff) suffers from guilt-induced insomnia after Carla (Judy Reyes) points out that he avoided a terminally ill patient because the man was a difficult pill. Meanwhile, Dr. Cox' (John C. McGinley) ex-wife Jordan (guest-star Christa Miller) interferes in his new relationship with medical student Kristin (guest star Kelli Williams, "The Practice"), and Turk (Donald Faison) and Elliot (Sarah Chalke) obsess over evidence that Dr. Kelso (Ken Jenkins) might be concealing a musical past.

When J.D. (Zach Braff) asks Dr. Cox (John C. McGinley) to give the residents a pep talk, Dr. Cox takes things a little too far by telling them that inevitably, they will eventually kill a patient or two, which throws the staff into a frenzy. Meanwhile, Carla (Judy Reyes) becomes so annoyed with Turk's (Donald Faison) stuffed dog Rowdy, she takes drastic measures to get rid of him. Elsewhere, Elliot (Sarah Chalke) fights for a patient to receive a heart valve, and becomes frustrated when Molly (guest star Heather Graham) steps in to thwart her efforts. Neil Flynn also stars.
