A lot is going on with Naomi including a community service, a lying boyfriend, and an evil sister who comes back.
In the next "90210", as a result of falsely accusing her faculty adviser of sexual harassment, Naomi is now required to complete community service and publicly apologizes to her peers for the trouble she has caused. Liam and his father, Finn (guest star Scott Patterson), reconnect and attempt to rebuild their relationship.
The gang is preparing for the SAT's when Silver disagrees with Teddy's decision to skip college to focus on his tennis career and things grow even more tense when she meets his movie star father, Spence (guest star Ryan O'Neal). Navid and Dixon host an underground gambling party that results in Dixon owing Mark (guest star Blake Hood) a lot of money.
Debbie reveals to Harry that she kissed another man, which forces the two to finally discuss their recent problems. Annie overhears their parents conversation and turns to Liam for support. Just when Naomi thinks her life is back on track, her evil sister Jen (guest star Sara Foster) returns to Beverly Hills.
"Multiple Choices" airs on April 27 because the show is taking a one-week break.
