Katey Sagal is set to make a notable return to Fox, joining the recurring cast of the medical series "Best Medicine" for its second season. Known for her iconic roles in shows like "Sons of Anarchy" and "Married … With Children," Sagal will portray Kathleen Gavin, the estranged mother of Louisa, played by Abigail Spencer. Her character is described as combative and conniving, earning her the nickname "Shady Katie" among the residents of Port Wenn, where she is notably unwelcome.

This role marks Sagal's return to Fox, a network that has been pivotal in her career, having launched her into the spotlight with her earlier work. The character of Kathleen Gavin promises to bring a new layer of drama to the series, as she navigates her complex relationship with her daughter Louisa, who has distanced herself from her mother for reasons yet to be explored in the show.S1S3
