90210 (2008) - 2x05 - Environmental Hazards

Naomi (AnnaLynne McCord) learns that her test scores may not be high enough for her to be accepted into CU. Devastated, Naomi devises a plan to be tutored by Richard (guest star Jonathon Trent, "CSI: NY"), the son of the school's dean of admissions, but quickly realizes she would much rather be studying Jamie (guest star Travis Van Winkle, "Meet the Spartans"), a CU student. Dixon's (Tristan Wilds) girlfriend, Sasha (guest star Mekia Cox, "Bones"), becomes suspicious about his age and does a little detective work to learn the truth, leaving Dixon devastated. Navid (Michael Steger) and Adrianna (Jessica Lowndes) double date with Teddy (Trevor Donovan), but Adrianna's growing feelings towards Teddy make for an awkward situation. Silver (Jessica Stroup) accompanies Adrianna to an AA meeting and surprisingly bumps into her mom, Jackie (guest star Gillespie), who tells Silver she would like to re-establish their relationship. An angry Silver rejects her mother, but her world is turned upside down when Adrianna reveals shocking news about Jackie.
