NAOMI IS FORCED TO TESTIFY DURING HER SEXUAL HARASSMENT HEARING, SCOTT PATTERSON GUEST STARS — Naomi’s (AnnaLynne McCord) little white lie has become the talk of the school, and when she is forced to testify in front of the school board, she drops a bomb that no one saw coming. Annie (Shenae Grimes) is finally able to put her relationship with Jasper (Zach Sherman, who does not appear in the episode) behind her, but when she and Silver (Jessica Stroup) inadvertently drive past the scene of her hit-and-run, the guilt comes rushing back to haunt her. Dixon (Tristan Wilds) and Ivy’s (Gillian Zinser) fake-dating situation continues and the two make a decision that neither one anticipated. Adrianna (Jessica Lowndes) and Navid (Michael Steger) share a friendly conversation which doesn’t go over well with their significant others, Gia (guest star Rumer Willis) and Lila (guest star Amber Wallace). An argument between Gia and Adrianna results in Adrianna walking in on Gia and her ex-girlfriend. Liam receives a surprise visit from his father, Finn (guest star Scott Patterson, “Gilmore Girls”), just released from prison. Though Ivy has warned Ryan (Ryan Eggold) that her mother is trouble, he continues to date Laurel (guest star Kelly Lynch). Rob Estes and Lori Loughlin also star. Millicent Shelton directed the episode written by Scott Weinger (#218).
