Phenom S01E13 - Brian and the Tennis Star

Lou's arranges for Marissa Guiteau, an attractive, outgoing French tennis player known for being a party girl, to stay at the Doolan home to keep her away from the L.A. nightlife and keep her focused on the game. Her arrival causes problems for Angela when Marissa flirts with Angela's boyfriend Jesse and repeatedly cheats during their tennis matches; Brian also catches Marissa's eye, at the same time that Roanne decides to take a "trial separation" from Brian because she thinks that he's too sensitive.
