“Killed?" said Hagrid loudly, staring down at Harry. "Snape killed? What're yeh on abou', Harry?""Dumbledore," said Harry. "Snape killed... Dumbledore.”
“Severus Snape wasn't yours," said Harry. "Snape was Dumbledores, Dumbledores from the moment you started hunting down my mother...”
“And what will you give me in return, Severus?’ ‘In – in return?’ Snape gaped at Dumbledore, and Harry expected him to protest, but after a long moment he said, ‘Anything...”
“Of course we still want to know you!" Harry said, staring at Hagrid."You don't think anything that Skeeter cow - sorry, Professor," he added quickly, looking at Dumbledore."I have gone temporarily deaf and haven't any idea what you said, Harry," said Dumbledore, twiddling his thumbs and staring at the ceiling.”
“Harry, despite your privileged insight into Voldemort’s world (which, incidentally, is a gift any Death Eater would kill to have), you have never been seduced by the Dark Arts, never, even for a second, shown the slightest desire to become one of Voldemort’s followers!”“Of course I haven’t!” said Harry indignantly. “He killed my mum and dad!”“You are protected, in short, by your ability to love!” said Dumbledore loudly.”
“Ah, go boil yer heads, both of yeh", said Hagrid. “Harry — yer a wizard.”
