The crowd of people get terrified at the moment when Harry and the corpse of Cedric appear at the border of the maze.
Nobody except Dumbledore believes Harry when he tells what had happened. Dumbledore asks him to stay right at this place until he comes back, but Alastor Moody pulls Harry towards the castle. Harry also gives him every information about what had happened in the last time. Moody asks him about You-Know-Who, his behaviour and his dealing against the other death eaters. Moody gets himself into an illusion and finally holds his wand against Harry. The true identity of the Professor appears. Just in time Professor Dumbledore, Professor McGonagall and Professor Snape arrive at the office of Professor Moody. Dumbledore shows everyone the truth about the Professor of Defence Against the Dark Arts.
Dumbledore gives Snape the order to get the truth potion and brings the house-elf Winky to Moody’s office and McGonagall gets the order to bring a black dog of Hagrid into his headmaster office.
Dumbledore clarifies exactly to the bewildered Harry what’s going on. Moody has been played by Barty Crouch jr. who used the Polyjuice Potion to play the role during the whole school year. Under the influence of truth potion Crouch tells them from his escape of Azkaban with the body switching with his mother, the happenings during the Quidditch World Championship, the murder at his father and finally the transfiguration of the Triwizard Cup into a Portkey.
