First Snowfall

S9 E8: Abby's family nightmare continues as she and her mother, Maggie (recurring guest star Sally Field - "Norma Rae"), search for Abby's missing brother, Eric (recurring guest star Tom Everett Scott), who Abby suspects is suffering from serious mental problems. The two women go to a Midwestern air force base, hoping to prevent Eric from being court-martialed for being absent without leave. Carter struggles to get out of Chicago to join Abby. Meanwhile, Corday treats a family of patients who, while building a snowman, were severely injured after being struck by a truck driver. She must help the father, Stuart (Jeff Kober), make a life-or-death decision. Corday also sympathizes with troubled surgical resident Paul Nathan (recurring guest star Don Cheadle) as he struggles with the increasing symptoms of his physical handicap.
