Chase Buell is one of the neighborhood boys who obsess over the Lisbon sisters. When the boys go over to the Lisbon house at the end of the novel with the intention of “saving” the girls, they proudly tell Lux that they can use Chase Buell’s car (which is actually his mother’s) to drive them somewhere far away. Lux indulges this idea, though she suggests that they should take the Lisbon family’s car because it’s bigger. She also starts unbuckling Chase’s belt and reaching into his pants, much to the utter and complete surprise of not just Chase but all of the other boys. But when Lux hears a thump (the sound of Bonnie hanging herself), she stops fiddling with Chase’s pants and says she’s going to wait in the garage, where she asphyxiates herself in her parents’ car.
