Harry (Rob Estes) and Debbie (Lori Loughlin) inform Annie (Shenae Grimes) and Dixon (Tristan Wilds) about Harry's son that was given up for adoption nearly 22 years ago. While Dixon doesn't seem bothered by the information, Annie releases her frustration and anger at a sleepover with Naomi (AnnaLynne McCord), Silver (Jessica Stroup) and Adrianna (Jessica Lowndes). The sleepover quickly turns into a house party with guys and drinking games. Meanwhile, Annie and Ethan (Dustin Milligan) decide to hide their relationship from their friends and Dixon opens up to Silver (Jessica Stroup) about his latest family issues. Adrianna and Navid (Michael Steger) continue to get close until she misunderstands his intentions. Now that Ryan (Ryan Eggold) is in on Kimberlys (guest star Jessica Lucas) secret, the two can no longer control their desire for each other but are oblivious when a student observes their actions.
