In the shattering conclusion of a two-part story, Carter (Noah Wyle) finds Lucy (Kellie Martin) lying in a pool of blood, stabbed and near death. No sooner has this sunk in than Carter is himself attacked and stabbed by Lucy's patient, delusional lawyer Paul Sobricki (David Krumholtz). Both victims are rushed to the operating room -- but only one will emerge alive. ~ Hal Erickson, Rovi
