Romano (Paul McCrane) surprises everyone when he promotes his longtime nemesis Elizabeth Corday (Alex Kingston) to associate chief of surgery. Returning from his mother's funeral, Greene (Anthony Edwards) is plunged into an argument with Weaver (Laura Innes) over a patient who is to be resuscitated. New second-year resident Malucchi (aka "Dr. Dave," played by Erik Palladino), manages to rub the entire staff the wrong way, especially Carter (Noah Wyle) during a medical crisis at a construction site. And can it be that Benton (Eriq La Salle) is not truly the biological father of little Reese (Matthew Watkins)? ~ Hal Erickson, Rovi
