We've cast Ellen Graff as Farrah!
Farrah clings to her peace and love days, where drugs were fun and AIDS was not yet in existence. She’s got that wisdom that comes from getting older and a frugal trait that comes from never relying on a significant other to provide financial security. Since the death of her wife, she has lived in the local nursing home and longs for her grandkids to have passionate, fulfilled lives.
