However, Peter discovers Liz's father is the supervillain Vulture. Peter, wishing to protect Liz from Adrian's criminal nature, is forced to leave Liz at the prom and go after Adrian himself, making Liz downtrodden. Thanks to Peter's efforts as Spider-Man, Adrian is arrested and sent to prison, which causes Liz and her mother to decide on moving to Oregon as Adrian didn't want them during his trial. While gathering her things from school, Liz expresses her dissatisfaction over what Peter did at the dance, but encourages him to move on and wishes him luck in his own endeavors.
