Donna finds herself in a dilemma when she confides in Kelly during a night on the town that she must decide between returning to Japan and being with David, or moving back to Beverly Hills and keeping their 20-month-old daughter, Ruby, which leads her to decide to open up her own design shop in Los Angeles. Meanwhile, Silver is the topic of gossip at West Beverly due to her recent mental issues and does not know if she is ready to return to school. While Annie and Naomi try to patch things up between them in order to help Silver, Annie soon overhears that Naomi's father is being served a sexual harassment lawsuit, and she keeps it to herself... and later regrets it when Naomi is evicted from her hotel suite. Ethan continues on his downward spiral due to Liam's bad influence in wanting to be a bad guy as Liam is. Also, Adrianna and Navid meet with potential adoptive parents for the baby. Elsewhere, Harry and Debbie hold a yard sale when they finally sell their Kansas house and try to get rid of all of their old house's possessions as they plan to move out of Tabitha's house and to find a house of their own in Beverly Hills.

Following their engagement, Navid and Adrianna celebrate their respective bachelor and bachelorette parties. While Adrianna feasts with Annie, Naomi, Silver, and their female friends at the Wilson home, Liam takes Navid, Ethan, and Dixon to have a wild night on the town with some college girls at a burlesque club. Meanwhile, sparks fly between Ryan and Jen, and Dixon continues to feel unappreciated by Silver. Jen also persuades Naomi to stand up to their father as well as move in with her at a local house, while Naomi continues to grow more insecure as well as jealous over Liam when she sees him talking with Annie whom he sees as naive and holding back her own dark side.
