Having completed medical school, Carter (Noah Wyle) invites Benton (Eriq La Salle) to his graduation -- only to miss the festivities himself because he's too busy comforting his patient TC (Gabrielle Boni). Meanwhile, Carol Hathaway (Julianna Margulies), fed up with the bureaucracy and backstabbing of hospital politics, quits her job; and Greene (Anthony Edwards) is forced to back Weaver (Laura Innes) for the job of attending physician if he wants to appoint Lewis (Sherry Stringfield) as chief resident. This final episode of ER's second season includes an unresolved plot strand involving Benton, his erstwhile lover, Jeanie (Gloria Reuben), and an HIV examination. ~ Hal Erickson, Rovi
