“Makes a diff'rence, havin' a decent family,' he said. 'Me dad was decent. An' your mum an' dad were decent. If they'd lived, life woulda bin diff'rent, eh?''Yeah, I s'pose,' said Harry cautiously. Hagrid seemed to be in a very strange mood.'Family,' said Hagrid gloomily. 'Whatever yeh say, blood's important...”
“Ah, go boil yer heads, both of yeh", said Hagrid. “Harry — yer a wizard.”
“Killed?" said Hagrid loudly, staring down at Harry. "Snape killed? What're yeh on abou', Harry?""Dumbledore," said Harry. "Snape killed... Dumbledore.”
