Bonnie is a cheerleader at West Beverly Hills High School. She is first seen at a pep rally for grudge week doing cheers. She briefly makes eye contact with Brandon Walsh and smiles during the cheering.
Bonnie later calls anonymously to a Teen hotline, where she gets into contact with Brenda Walsh after the phone lines have closed. She questions whether or not she was raped by a guy she likes. She calls again the next night, crying, upset, and stating that she was raped once again behind the gym.
She later briefly runs into Dylan McKay in the hallway and apologizes. She later calls the hotline again and reports a third rape, this time with two guys. Brenda figures out who she is and approaches her in the hallway. Bonnie reacts with anger, telling Brenda she's jealous of her popularity and storms away.
After the last grudge week event, Bonnie is getting into her car when George Sudaris and a friend try to rape her again, but Brenda alerted the police ahead of time and the rape was prevented and George arrested.
