Abby's (Maura Tierney) bipolar mother, Maggie (Sally Field), testifies in court as to her competency, with surprising results. Back at the ER, Weaver (Laura Innes) is shocked to learn that her latest patient, a homeless derelict (Bette Ford), is actually "Princess Taffeta," Weaver's favorite kiddie-show host. Benton (Eriq La Salle) treats a repeat heart patient, his former teacher Carl Ferris (Roger Robinson). Palladino's (Erik Palladino) turbulent past catches up with him. And Carter (Noah Wyle) treats a young girl whose boyfriend has been trying to abort her baby through "natural" means. ~ Hal Erickson, Rovi
