Justin Finch-Fletchley

Justin Finch-Fletchley is a Hufflepuff student in Harry's year, and a Muggle-born who was originally headed for Eton until he discovered that he was a wizard at age eleven. He is Sorted in Philosopher's Stone but makes his first proper appearance in Chamber of Secrets, in which he is threatened by a snake conjured up by Malfoy during Gilderoy Lockhart's disastrous Dueling Club, and Harry orders the snake to relent by speaking Parseltongue; it is initially believed that Harry was encouraging the snake to attack. Despite Ernie Macmillan's subsequent order that he stay in his dormitory, Justin is later petrified by the basilisk along with Hermione, Colin Creevey, and Penelope Clearwater.
In Goblet of Fire, under the impression that Harry was attempting to steal fellow Hufflepuff and Triwizard Tournament entrant Cedric Diggory's glory by entering the competition, Justin and Ernie temporarily give Harry the silent treatment. Justin joins Dumbledore's Army in his fifth year in Order of the Phoenix; during practice of the Expelliarmus Charm at one meeting, Luna succeeds in disarming him, but also in entangling him in his robes and causing his hair to stand on end. He is part of the group of D.A. members who successfully defend Harry against Malfoy, Crabbe, and Goyle aboard the Hogwarts Express at the end of the term, which also marked his last appearance in the series.
Justin was played by Edward Randell in the film adaptation of Chamber of Secrets
