Lauren Graham had a four-episode run as Andrea, a manipulative efficiency expert who shakes up the office (firing Matthew, demoting Dave, and promoting Lisa). She is sometimes referred to as "Planbee" after Matthew misunderstands her being Jimmy's "Plan B" for the office. In a season 4 episode commentary track, Tierney gives the hiring of Graham as a possible explanation for Alexander's departure, which contradicts the idea that Alexander intended to leave before Graham appeared on the show. (In Dave Foley's appearance on Joe Rogan's podcast, they talked about Alexander leaving because she was not given enough lines.) All of the changes introduced during Graham's time on the show would be restored by mid-season to the way things were before her arrival.
