Lisa is this cool, smart, chill and friendly girl, who enters the Tournament of Roses Royal Court alongside Donna. She works a cashier at a convenience store in a rough Los Angeles neighborhood.
Lisa becomes friends with Donna Martin during the competition and eventually wins the Rose Queen of the Royal Court title, defeating Donna and all of the other girls. When Ray Pruit shows up to confront Donna after filing assault charges against Joe Bradley, Lisa is quick to not leave Donna alone with him, having been told of Ray's abusive behavior. Donna later fills in for Lisa at work, while Lisa performs her Rose Queen duties.
