Sirius Black Quotes in Harry Potter and the Half-Blood Prince
[Harry] could not quite keep a note of derision out of his voice; it was hard to sympathize with Slughorn’s cosseted existence when he remembered Sirius, crouching in a cave and living on rats. “Most of the teachers aren’t in it, and none of them has ever been killed – well, unless you count Quirrell, and he got what he deserved seeing as he was working with Voldemort.”
His eyes burned suddenly and he blinked. He felt stupid for admitting it, but the fact that he had had someone outside Hogwarts who cared what happened to him, almost like a parent, had been one of the best things about discovering his godfather…and now the post owls would never bring him that comfort again…
“You are determined to hate him, Harry,” said Lupin with a faint smile. “And I understand; with James as your father, with Sirius as your godfather, you have inherited an old prejudice. By all means tell Dumbledore what you have told Arthur and me, but do not expect him to share your view of the matter…”
…People who cared about him had stood in front of him one by one, his mother, his father, his godfather, and finally Dumbledore, all determined to protect him; but now that was over. He could not let anybody else stand between him and Voldemort; he must abandon forever the illusion he ought to have lost at the age of one, that the shelter of a parent’s arms meant that nothing could hurt him. There was no waking from this nightmare, no comforting whisper in the dark that he was safe really…the last and greatest of his protectors had died, and he was more alone than he had ever been before.
