NAOMI IS TAKEN HOSTAGE BY HER RAPIST - Naomi (AnnaLynne McCord) is taken hostage in her own home by an out-of-control Mr. Cannon (guest star Hal Ozen) who also lures Silver (Jessica Stroup) into the situation. Annie (Shenae Grimes) and Dixon's (Tristan Wilds) cousin Emily (guest star Abbie Cobb, "Jonas") from Kansas comes to town for an extended visit, but Emily immediately gets on Annie's nerves. Dixon confronts Teddy (Trevor Donovan) about his kiss with Ian (guest star Kyle Riabko) and promises to keep his secret. During surf practice, Ivy (Gillian Zinser) takes a nasty spill that makes her question her ability to compete in the surf competition. Adrianna's (Jessica Lowndes) world continues to crumble when she appears on a talk show to tell her side of the story, and she is blindsided by a surprise guest. Given Adrianna's disastrous situation, Navid (Michael Steger) and Silver continue to keep their hook-ups a secret. Lori Loughlin and Ryan Eggold also star. Stuart Gillard directed the episode written by Tod Himmel (312).
