Hermione Granger organizes a meeting with some of the other students at Hog's Head, where Barman works. Somewhat Doubtful Boy wonders why they need to be taught how to combat the dark arts and Slightly Creepy Boy asks Harry Potter to describe more of what happened when Cedric Diggory was killed. Nigel asks if Voldemort is really back, and Harry tells everyone he is. They then form a group called Dumbledore's Army. Dumbledore's Army, which consists of Harry, Hermione, Ron Weasley, Fred Weasley, George Weasley, Ginny Weasley, Neville Longbottom, Cho Chang, Nigel, Dean Thomas, Padma Patil, Parvati Patil, Somewhat Doubtful Boy, Slightly Creepy Boy and others, uses the Room of Requirement to train. More students join Dumbledore's Army. During one of their training sessions, they are caught by Dolores Umbridge, Mr Filch and the student members of the inquisitors. Dolores replaces Dumbledore as head of Hogwarts and all members of Dumbledore's Army are required to go to detention where they are forced to experience the same abuse as Harry was.
