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. Dixon (Tristan Wilds) realizes he and Sasha (guest star Mekia Cox, "Bones") are in two different places in their life and decides to end their relationship, but she ends up delivering life-changing news. Tensions rise between Debbie (Lori Loughlin) and Harry (Rob Estes) when she walks in on Harry and Kelly in his office.

Liam ran over Ivy's surfboard. Ivy is his new love interest. After Sasha keeps pulling Dixon away from his surf club to where he almost gets kicked off the team, Dixon breaks up with her. Sasha later apologizes for being a needy girlfriend then reveals that she is pregnant. Naomi continues to date the dean's son. She flirted with his roommate, Jamie. They chatted about her love of the university. Naomi see's Liam talking to Ivy and realizes that she needs to move on as well. She breaks off her faux relationship with Richard and asks Jamie to the Halloween party.
Annie and Jasper continue to spend time together, even after Dixon warns her that Jasper is not someone that could be trusted. Annie rebuts by saying that Dixon sneaks out of the house every night. Annie volunteers to be in Jasper's film. She helped him steal a car from the beach house for the movie. Back at home, Debbie and Harry argue over Harry's relationship with Kelly. Harry calls Kelly and tells her about Debbie's suspicion and it is revealed that there is some truth; Kelly does have a crush on Harry.
Silver has been taking care of her mother, Jackie, by herself. She is so preoccupied with that she forgets to do a homework assignment and Teddy ends up getting her in trouble for it.
