Elizabeth (Alex Kingston) lashes out at Rachel (Hallee Hirsh) for nearly causing baby Ella's death. Greene (Anthony Edwards) worries that his brain tumor has returned. Carter's (Noah Wyle) mother (Mary McDonnell) continues "coping" with the long-ago death of her other son, Bobby, by living her life vicariously through a young leukemia patient. Lewis (Sherry Stringfield) is forced to hold down the ER fort virtually by herself when a bag of bad bagels causes the other staffers to suffer from food poisoning. And Abby (Maura Tierney) is attacked and beaten by her neighbor Brian (Matthew Settle) for offering support to Brian's abused wife. ~ Hal Erickson, Rovi
