“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 . . .”
“As he followed Bill back to the others a wry though came to him, born no doubt of the wine he had drunk. He seemed set on course to become just as reckless a godfather to Teddy Lupin as Sirius Black had been to him.”
“With another shock of excitement, Harry saw Sirius give James the thumbs-up.Sirius was lounging in his chair at his ease, tilting it back on two legs. He was very good-looking, his dark hair fell into his eyes with a sort of casual elegance neither James's nor Harry's could ever have achieved, and a girl sitting behind him was eyeing him hopefully, though he didn't seem to have noticed.”
“Does it hurt?" The childish question had escaped Harry's lips before he could stop it. "Dying? Not at all," said Sirius. "Quicker and easier than falling asleep.”
“Only one pair was still battling, apparently unaware of the new arrival. Harry saw Sirius duck Bellatrix's jet of red light: he was laughing at her.'Come on, you can do better than that!' he yelled, his voice echoing around the cavernous room.The second jet of light hit him squarely in the chest.The laughter had not quite died from his face, but his eyes widened in shock.”
“Beside him, making scarcely a sound, walked James, Sirius, Lupin, and Lily, and their presence was his courage, and the reason he was able to keep putting one foot in front of the other.”
