Which girl does Kevin briefly go steady with before breaking up over Winnie?

Kevin briefly goes steady with Becky Slater before breaking up with her because of his feelings for Winnie Cooper. Becky is Kevin’s junior-high classmate and one-time girlfriend, introduced as part of the early romantic complications surrounding Kevin and Winnie.

Kevin’s relationship with Becky is not presented as a deep or lasting romance. He dates her while Winnie is seeing Kirk McCray, and Becky later realizes that Kevin still cares about Winnie. When the relationship ends, Becky becomes resentful and turns into a recurring nuisance in Kevin’s junior-high years.

Becky’s character also has an unusual production connection: Crystal McKellar, Danica McKellar’s sister, played Becky. Producers liked Crystal during casting and created the role after Danica was chosen to play Winnie.
