“And I must draft an advertisement for the Daily Prophet, too,' he added thoughtfully. 'We'll be needing a new Defense Against the Dark Arts teacher.... Dear me, we do seem to run through them, don't we?”
“Ron and Hermione were still smirking and Harry felt his temper rise; he wasn’t even sure why he was feeling so angry.“Don’t sit there grinning like you know better than I do, I was there, wasn’t I?” he said heatedly. “I know what went on, all right? And I didn’t get through any of that because I was brilliant at Defense Against the Dark Arts, I got through it all because — because help came at the right time, or because I guessed right — but I just blundered through it all, I didn’t have a clue what I was doing — STOP LAUGHING!”
“Oh, come off it,” said Ron, striding over to her and whipping her results out of her hand. “Yep— ten ‘Outstandings’ and one ‘Exceeds Expectations’ at Defense Against the Dark Arts.” He looked down at her, half-amused, half-exasperated. “You’re actually disappointed, aren’t you?”
“They run off eckeltricity, do they?" he said knowledgeably. "Ah yes, I can see the plugs. I collect plugs," he added to Uncle Vernon. "And batteries. Got a large collection of batteries.”
“Hang on . . .” Harry muttered to Ron. “There’s an empty chair at the staff table. . . . Where’s Snape?”"Maybe he's ill!" said Ron hopefully. “Maybe he’s left,” said Harry, “because he missed out on the Defense Against the Dark Arts job again!”“Or he might have been sacked!” said Ron enthusiastically. “I mean, everyone hates him —”“Or maybe,” said a very cold voice right behind them, “he’s waiting to hear why you two didn’t arrive on the school train.”Harry spun around. There, his black robes rippling in a cold breeze, stood Severus Snape.”
“Why, dear boy, we don't send wizards to Azkaban just for blowing up their aunts.”
“We'll be there, Harry," said Ron"What?""At your Aunt and Uncle's house," said Ron, "And then we'll go with you wherever you're going.""No-" said Harry quickly; he hadn't counted on this, he had meant them to understand that he was undertaking the most dangerous journey alone. "You said it once before," said Hermione quickly, "that there was time to turn back if we wanted to. We've had time, haven't we? We're with you whatever happens.”
