We’ve already met Ben’s parents ( Jonathan Banks and Glenne Headly), so now it’s time to meet his sister. Annabeth Gish (The X-Files, Mystic Pizza) has been cast as Adam Scott’s onscreen sibling on Parks and Recreation, EW has learned.

In an episode of the NBC comedy set to film next week and air later this season, Ben and fiancée Leslie (Amy Poehler) take a road trip to his hometown of Partridge, Minn., where they meet up with his sister, Stephanie (Gish). Homecoming week should be interesting, as Ben briefly served as the town’s mayor at age 18 before being impeached.
