After the incident with the pixies, Lockhart reverts to role playing in his Dark Arts class. Hermione approaches Lockhart at the end of class and asks for permission to get a book out of the restricted section of the library, in order to better understand the tactics employed in one of his books. Lockhart is very flattered by this attention paid to his works, so he signs the slip, and Harry, Hermione, and Ron hurry into the library, where they are given the book. They read about the painful and complicated steps to making and using Polyjuice potion, and by the end Hermione is the only one still interested in trying to make it, although she persuades the boys to join her. The Quidditch match between Gryffindor and Slytherin dawns, and during the Gryffindor team pep talk, Oliver Wood reassures his team that while the Slytherins have better brooms, the Gryffindors have better people on their brooms. He then tells Harry to get the Snitch or die trying. The game begins, and as soon as Harry is circling through the air looking for the Snitch, a Bludger streaks toward him, and continues to aim for him, even after knocked away by Fred and George. While the two beaters are protecting Harry, the Slytherins are scoring goal after goal, and during the time out talk, Harry requests that Fred and George return to the game, allowing him to fend against the Rogue Bludger for himself while he looks for the Snitch. Malfoy, the Slytherin seeker, laughs at Harry for his twirling evasions of the Bludger, and while he is laughing, Harry notices the Snitch next to his face. Harry pauses, is whacked by the Bludger, recovers quickly and flies at Malfoy, grabbing the Snitch and falling out of the sky. Harry wins the game but lands painfully, and he is greeted on the ground by Lockhart, who immediately sets to repair his broken arm but makes a mistake and de bones it. Harry is sent to the hospital wing where he must stay the night, waiting for his arm to re grow itself through a lengthy and painful process. During the night, he is visited by Dobby, who explains that he had closed up the train platform and bewitched the Bludger, both in hopes that Harry would give up and return home and away from Hogwarts, where his life would be threatened because the Chamber of Secrets had been opened again. Harry perks up at this knowledge, wanting to know more from Dobby, but the house elf is adamant about saying nothing more, and soon footsteps sound in the corridor and Dobby disappears. Dumbledore enters with Professor Mcgonagall, together carrying a stony figure that Harry soon recognizes as Colin Creevey, who has been petrified with his camera in front of his face. Dumbledore gravely reiterates what Dobby had said, that the Chamber of Secrets has been opened again.
