As Dixon (Tristan Wilds) continues to recuperate, Adrianna (Jessica Lowndes) confides in Annie (Shenae Grimes) that she and Dixon are having intimacy issues. Annie grows closer to Colin (guest star Rob Mayes), but Riley (guest star Riley Smith) suspects that Colin isn’t who he appears to be. Colin discovers that Alex (Trai Byers) installed a GPS tracking app on Naomi’s (AnnaLynne McCord) phone so he can track her whereabouts, but Colin reconfigures her phone so she can secretly read Alec’s emails, which exposes Alec’s efforts to sabotage Max’s (Josh Zuckerman) relationships. Navid (Michael Steger) hopes to show Silver (Jessica Stroup) how successful he’s become with the launch of the Pop Up, but he becomes suspicious that Silver and Liam (Matt Lanter) are secretly seeing each other. Lindsey (Peyton List) comes to the opening event to discuss Liam’s business plan, and their animosity gives way to passion.
