This looks to be a good one, and judging by the title, we’re back to the Pi Sigs.
Lord of the Pi’s. Selma Rose (guest star Patricia Hearst), the wealthy grand-daughter of the founder of Hearst College and a member of the Hearst College Board of Trustees, mysteriously disappears the night before she is to cast a swing vote that will determine the fate of the Greek system on campus. Keith (Enrico Colantoni), with Veronica’s (Kristen Bell) help, is hired by Dean O’Dell (guest star Ed Begley, Jr., "Arrested Development") to investigate the disappearance. Meanwhile, Veronica has been rehired as a photographer at the Hearst Free Press, but she and Logan (Jason Dohring) fight over her involvement in the rape case. Percy Daggs III, Francis Capra, Ryan Hansen, Michael Muhney, Tina Majorino, Chris Lowell and Julie Gonzalo also star. Steve Gomer directed the episode written by Diane Ruggiero.
