Terry Boot

Terry Boot is a Ravenclaw student in Harry's year who is close friends with housemates Michael Corner and Anthony Goldstein. In Order of the Phoenix, Terry becomes a member of Dumbledore's Army at the first meeting at the Hog's Head. After one D.A. meeting in the Room of Requirement, Terry is impressed by Hermione's charmed communication-device Galleons distributed among the members, as well as her ability to perform the N.E.W.T.-level Protean Charm. He is among the six D.A. members who assist Harry when Malfoy, Crabbe and Goyle attempt to ambush him aboard the Hogwarts Express at the end of the term. In Half-Blood Prince, Terry appears in Horace Slughorn's Advanced Potions class, and is physically punished by the Carrows in his seventh year after shouting an announcement in the Great Hall about Harry, Ron, and Hermione's Gringotts bank break-in and their escape on a dragon. He is among the D.A. members who later seek refuge in the Room of Requirement prior to Harry's return to Hogwarts, and provides Ron with an explanation of Ravenclaw's diadem.
Terry's first name was originally "Trevor" on Rowling's original pre-canon classlist that she created prior to the completion of Philosopher's Stone.[3] He has yet to appear in any of the films, but was included in the Order of the Phoenix video game.
