Homer treats Valentine as a kind of “consolation prize”—he would have preferred to dance with Dorothy, but he’ll settle for Valentine instead. It’s implied that Homer loses his virginity to Valentine, though Hickam doesn’t say so explicitly. It’s no coincidence that Homer feels sympathy for Buck immediately after he loses his virginity. Hickam suggests that Homer has become more mature (and sexual maturity is part of this), developing genuine sympathy even those who show nothing but disdain for him. This contrasts to the early scene where Homer mocked Buck for losing his sports scholarship.
