It’s Halloween at the Beverly Hills Beach Club and Adrianna (Jessica Lowndes) channels Marilyn Monroe to help her deal with the end of her relationship with Navid (Michael Steger). Silver (Jessica Stroup) and Kelly (Jennie Garth) continue to have differing opinions about caring for Jackie (Ann Gillespie). Silver is overloaded with school work and caring for her mom, but soon learns that she and Teddy (Teddy Donovan) have more in common than a class project. Naomi (AnnaLynne McCord) continues her relationship with Richard (guest star Jonathon Trent, “CSI: NY”), but when she and Jamie (guest star Travis Van Winkle, “Meet the Spartans”) share an intimate conversation, her plans to schmooze with the dean of CU come to a screeching halt.
