Greene (Anthony Edwards) is a changed man after the departure of Susan Lewis -- and the change is not for the better. Surreptitiously checking into Jeanie's (Gloria Reuben) confidential file, Greene learns the truth about her HIV status. Meanwhile, Carter (Noah Wyle) is taken aback by Keaton's (Glenne Headly) travel plans, and Benton (Eriq La Salle) bears down even harder on Gant (Omar Epps). ~ Hal Erickson, Rovi
