One of Harry's fellow third-year Gryffindors. Neville lives with his grandmother and struggles at school. Though he's very kind, his lack of confidence means that he often messes up when he tries to perform spells. His fear of Professor Snape in particular means that Potions is his worst subject; Snape doesn't help Neville at all and actively terrorizes him during classes. Neville suffers even more derision and ridicule after Professor McGonagall learns that Neville wrote down all of Sir Cadogan's passwords, as the paper somehow ends up in Sirius Black's hands. Though he's punished at the time for losing the paper and putting students at risk, Harry, Ron, and Hermione learn in the Shrieking Shack that Crookshanks stole the paper from the dormitory and it wasn't Neville's fault.
