Hagrid dropped the teapot.
“How do you know about Fluffy?” he said.
“Fluffy ?”
“Yeah — he's mine — bought him off a Greek chappie I met in the pub las’ year — I lent him to Dumbledore to guard the—”
“Yes?” said Harry eagerly.
“Now, don't ask me anymore,” said Hagrid gruffly. “That's top secret, that is.”
“But Snape's trying to steal it.”
“Rubbish,” said Hagrid again. “Snape's a Hogwarts teacher, he'd do nothin’ of the sort.”
“So why did he just try and kill Harry?” cried Hermione.
The afternoon's events certainly seemed to have changed her mind about Snape.
“I know a jinx when I see one, Hagrid, I've read all about them! You've got to keep eye contact, and Snape wasn't blinking at all, I saw him!”
“I'm tellin’ yeh, yer wrong!” said Hagrid hotly. “I don’ know why Harry's broom acted like that, but Snape wouldn’ try an’ kill a student! Now, listen to me, all three of yeh — yer meddlin’ in things that don’ concern yeh. It's dangerous. You forget that dog, an’ you forget what it's guardin', that's between Professor Dumbledore an’ Nicolas Flamel—”
“Aha!” said Harry, “so there's someone called Nicolas Flamel involved, is there?”
Hagrid looked furious with himself.
