90210 Episode 5.06 The Con

Liam (Matt Lanter) and Lindsey (guest star Peyton List) keep their relationship under wraps, but when Navid's (Michael Steger) jealous streak gets the best of him, he arranges for Liam and Lindsey's sex tape to be shown in place of Liam's movie premiere at Phenomi-com. Riley (guest star Riley Smith) admits his feelings to Annie (Shenae Grimes), but Annie's more interested in giving her relationship with Colin (guest star Rob Mayes) a chance. Meanwhile, Max (Josh Zuckerman) tries to figure out how his company's video game technology got hacked, so Naomi (AnnaLynne McCord) and Alec (Trai Byers) work together to demo a new video game at Phenomi-con. Taylor (Wes Brown) feels guilty for hooking up with Adrianna (Jessica Lowndes), so he tells her to end things with Dixon (Tristan Wilds) if she wants to be with him. Dixon collapses due to a spinal infection, and Adrianna learns that he stopped taking his pain medication because he was afraid to become addicted again.
