Originally introduced in the first series, Erin, commonly called by her last name, is Kelly Taylor's and David Silver’s half-sister. She publishes her own blog called The Vicious Circle, which she uses to discuss intimate details (truth or fiction) about her peers at West Beverly High School. She becomes best friends with Annie and develops a romantic interest in Dixon, which quickly blossoms into a relationship. Before the start of the first season, we learn that Silver has shared the information of father's affair with her then-best-friend Naomi. Naomi makes this public knowledge, causing Silver's mother to turn to drink. In "By Accident" Dixon dumps her after taking advice from his mother Debbie, but later in "Help Me, Rhonda" they get back together after Silver says that she loves him. She loses her virginity to Dixon on Valentine's Day. Silver has always had a slightly manic personality, but in "Life's a Drag" she becomes more unbalanced. She visits Dixon at the Peach Pit where they end up having sex and Silver secretly taped it and then shows the tape to an entire theater, causing Dixon to break up with her. She ends up breaking into Ryan Matthews' house, claiming that he destroyed her relationship with Dixon, and threatening him with a bottle of wine unless he fixes everything. Silver then attempts to run away to Kansas, stating repeatedly that going there would help her solve her problems with Dixon. A stranger finds her while she is saying random things and acting erratically. The stranger then calls someone to come get her. Dixon and his mother and father find her on the train tracks. Dixon then remembers about his birth mother having bipolar disorder and says that Silver suffers from it also. Dixon calms Silver down and they take her to the hospital. Soon Silver finds it unbearable to go back to West Beverly High and results to going to St. Claire's School for a better semester. Silver wins the West Bev "prom queen" at that year's prom, but admits that she's not prom material. It is soon mentioned to Silver that Ethan has a crush on her. In the season finale Ethan and Silver share a kiss. In season 2, Teddy, Adrianna's ex boy-friend wants to go out with her and kisses her in the Winter Wonderland dance, but later sees Teddy with the another girl but not knowing it's his sister, Silver is kissed by Dixon. Teddy's father goes to see Silver and bribes her to break up with Teddy, even though she doesn't take the money, she starts thinking about what his father said so she breaks up with Teddy. In the season finale, she tells him she is sorry and that she loves him and they reconcile.
