S11, E14: Weaver encounters an evasive patient, Helen Kingsley (Frances Fisher - "Titanic," "House of Sand and Fog"), who shocks her by revealing that she is her birth mother, who at the age of 15 delivered Weaver and put her up for adoption. As they share life stories, their budding relationship withers when Weaver confesses to the evangelical Christian that she's a lesbian. Meanwhile, Pratt warily assigns Jane (recurring guest star Sara Gilbert - "Roseanne") to attend to a confused elderly woman, while Carter causes a commotion when he confronts a scheming couple hoping to get some painkilling drugs.
