Kovacs' (Goran Visnjic) car accident and disastrous misdiagnosis has left a patient with profound brain damage. While Weaver (Laura Innes) suffers from the side effects of her "secret" pregnancy, Abby (Maura Tierney) covers for her at the ER. The heightened security measures at County General ensnare Pratt (Mekhi Phifer), who is packing a gun -- thereby placing Carter (Noah Wyle) in an unenviable position. Gallant (Sharif Atkins) squares off against the mercenary young bride (Sofia Milos) of an elderly patient (Patrick Cranshaw). And Lewis (Sherry Stringfield) keeps a suicide watch on a self-admitted child molester. Edward Asner makes the first of several appearances as Dr. James McNulty, the crusty head of a storefront clinic. ~ Hal Erickson, Rovi
