Season 2, Ep. 1: Veronica Cares For Archie After the Shooting
Boy oh boy is this episode jam-packed. After Archie's dad is shot at the end of season one, Veronica rushes to his side to help through the trauma. She takes Archie back to his house to get Fred Andrews clothes and makes Archie shower, where she joins him (wearing only her pearls), which is super hot. This event also brings the couple closer together as Archie leans on Veronica while he tries to heal.
