“She should've interviewed Snape," said Harry grimly. "He'd give her the goods on me any day. "Potter has been crossing lines ever since he first arrived at this school...”

“Harry Potter must not go back to Hogwarts.“Harry Potter must stay where he is safe. He is too great, too good, to lose. If Harry Potter goes back to Hogwarts, he will be in mortal danger.”“Why?” said Harry in surprise.“There is a plot, Harry Potter. A plot to make most terrible things happen at Hogwarts School of Witchcraft and Wizardry this year.”

“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.”

Since then I've been thinking what I would lose if I cross my line & I haven't come up with anything either. There's always another line somewhere.”

“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...”

“Dudley had been accepted at Uncle Vernon's old private school, Smeltings...Harry, on the other hand, was going to Stonewall High, the local public high school. Dudley thought this was very funny. "They stuff people's heads down the toilet the first day at Stonewall," he told Harry. "Want to come upstairs and practice?" "No, thanks," said Harry. "The poor toilet's never had anything as horrible as your head down it - it might be sick." Then he ran, before Dudley could work out what he'd said.”
