“Nasty temper he's got, that Sirius Black.”

“He's not a child!" said Sirius impatiently."He's not an adult either!" said Mrs. Weasley, the color rising in her cheeks. "He's not James, Sirius!""I'm perfectly clear who he is, thanks, Molly," said Sirius coldly."I'm not sure you are!" said Mrs. Weasley. "Sometimes, the way you talk about him, it's as though you think you've got your best friend back!”

“Sirius — it’s me . . . it’s Peter . . . your friend . . . you wouldn’t . . .”Black kicked out and Pettigrew recoiled.“There’s enough filth on my robes without you touching them,” said Black.”

“It seemed impossible that there could be people in the world who still desired food, who laughed, who neither knew nor cared that Sirius Black was gone forever.”

“I know [Umbridge] by reputation and I'm sure she's no Death Eater—''She's foul enough to be one…''Yes, but the world isn't split into good people and Death Eaters', said Sirius with a wry smile. 'I know she’s a nasty piece of work though'.”

“But some part of him realized, even as he fought to break free from Lupin, that Sirius had never kept him waiting before. . . . Sirius had risked everything, always, to see Harry, to help him. . . . If Sirius was not reappearing out of that archway when Harry was yelling for him as though his life depended on it, the only possible explanation was that he could not come back. . . . That he really was . . .”

“Oh, for heaven’s sake, Sirius, Dumbledore said no!”A bearlike black dog had appeared at Harry’s side as Harry clambered over the various trunks cluttering the hall to get to Mrs. Weasley.“Oh honestly,” said Mrs. Weasley despairingly. “Well, on your own head be it!”The great black dog gave a joyful bark and gamboled around them, snapping at pigeons, and chasing its own tail. Harry couldn’t help laughing. Sirius had been trapped inside for a very long time.”
