Diane Carter

Diane Carter was a Slytherin student at Hogwarts School of Witchcraft and Wizardry in the 1990s. On the day of her Sorting, she was extremely happy to be placed in Slytherin, as she couldn't imagine being with "those Gryffindor weirdoes." During the 1996-1997 school year, she confronted Harry Potter in the Viaduct, challenging him to a duel.
