Kim goes into labor, and J.D. struggles to decide if he should tell her what he really thinks of their relationship. Turk, desperate to do something not baby-related, races to beat a video game before Carla discovers him. And Dr. Cox searches for someone he trusts enough to give his daughter a shot.

Turk tries to assure a worried Carla that their daughter will acknowledge her Latin heritage. Meanwhile the Janitor challenges J.D. to identify everyone in the hospital, when it is discovered that he uses nicknames, because he doesn't know the people's actual names. If J.D. can't name all of them, he must take up the mop for a day. Elsewhere, Dr. Cox realizes that he is lonely without his wife and children.
