90210: There's No Place Like Homecoming

Annie prepares for her driver's test and works out a plan with Ethan so they can attend the Homecoming dance without officially making it a date. Adrianna confesses about her drug use, effectively clearing Naomi's name, and is forced to check into rehab for her addiction. With no one left to turn to, Adrianna finds Navid by her side, determined to help her through her pain. At the dance, Ryan catches Kimberly buying drugs from a student but is even more surprised to learn that she is an undercover cop. After a conversation with Tabitha, Debbie confronts Tracy about her inappropriate behavior towards Harry, and despite her root canal pain, Silver and Dixon dance the night away.
