Harry was in Sirius's room in Grimmauld place. He had been escorted there after the nasty dementor attack he and his cousin encountered. Anyway, Mrs. Weasley told Harry to go up stairs where he would meet Ron and Hermione in one of the rooms while she and the rest of the Order went to a meeting. Harry ended up in Sirius room instead. Buckbeak was there chewing on something metal. "What do you have there Buckbeak?" Harry asked walking towards the creature. Harry tooked the metal thing out of Buckbeaks mouth and realized that it was a time turner. Before he could ask himself how Buckbeak ended up with the time turner, it started to tick and before he knew it a bright flash happened as he was knocked unconsious.
