After Sirius finds out what Umbridge has been doing to Harry, he promises him to take care of it. Harry asks how and Sirius only says that he got to know a few people in Azkaban. A few days later, he sneaks them out of Grimmauld under Harry's cloak and leads his godson through the Leakey Cauldron, through Diagon Alley and into Knockturn Alley. At this point, Harry is thoroughly confused, especially when Sirius knocks three times on a random door. They are led inside and Harry quickly realised that he's surrounded by hired muscle. To his surprise, they greet Sirius warmly and lead then through the house, up the stairs to the boss. Waiting behind a large desk is a beautiful woman, who is vaguely familiar. But it is not until she is introduced as Lady Delacour when Harry remembers that he had last seen her before, when Fleur met her family before the Third Task.
