“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...”

“Severus Snape wasn't yours," said Harry. "Snape was Dumbledores, Dumbledores from the moment you started hunting down my mother...”

“Hide them all, then. Keep her – them – safe. Please.'And what will you give me in return, Severus?'In – in return? Anything.”

“You are determined to hate him [Snape], 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; do not even expect him to be surprised by what you tell him. It might have been on Dumbledore’s orders that Severus questioned Draco.”

“Killed?" said Hagrid loudly, staring down at Harry. "Snape killed? What're yeh on abou', Harry?""Dumbledore," said Harry. "Snape killed... Dumbledore.”

“But this is touching, Severus,” said Dumbledore seriously. “Have you grown to care for the boy, after all?”“For him?” shouted Snape. “Expecto Patronum!”From the tip of his wand burst the silver doe. She landed on the office floor, bounded once across the office, and soared out of the window. Dumbledore watched her fly away, and as her silvery glow faded he turned back to Snape, and his eyes were full of tears.“After all this time?”“Always,” said Snape.”
