Christy (played by Faris) met up with her long-lost father Alvin (Kevin Pollak) on the show's latest episode, but the reunion wasn't exactly what she expected. In spite of her mother's wishes, Christy awkwardly introduced her kids Violet (Sadie Calvano) and Roscoe (Blake Garrett Rosenthal), to their grandfather on Monday night.
You can check out a clip of Christy's mother Bonnie (Allison Janney) reacting to her ex's return below.
