“This is your copy of Advanced Potion-Making, is it, Potter?”“Yes,” said Harry, still breathing hard.“You’re quite sure of that, are you, Potter?”“Yes,” said Harry, with a touch more defiance.“This is the copy of Advanced Potion-Making that you purchased from Flourish and Blotts?”“Yes,” said Harry firmly.“Then why,” asked Snape, “does it have the name ‘Roonil Wazlib’ written inside the front cover?”Harry’s heart missed a beat. “That’s my nickname,” he said.”

“Yes, Harry Potter!” said Dobby at once, his great eyes shining with excitement. “And if Dobby does it wrong, Dobby will throw himself off the topmost tower, Harry Potter!”“There won’t be any need for that,” said Harry hastily.”

“What is the difference, Potter, between monkshood and wolfsbane?"At this, Hermione stood up, her hand stretching towards the dungeon ceiling.I don't know," said Harry quietly. "I think Hermione does, though, why don't you try asking her?" A few people laughed; Harry caught sight of Seamus's eye and Seamus winked. Snape, however, was not pleased.Sit down," he snapped at Hermione. "For your information, Potter, asphodel and wormwood make a sleeping potion so powerful it is known as the Draught of Living Death. A bezoar is a stone taken from the stomach of a goat and it will save you from most poisons. As for monkshood and wolfsbane, they are the same plant, which also goes by the name of aconite. Well? Why aren't you all copying that down?"There was a sudden rummaging for quills and parchment. Over the noise, Snape said, "And a point will be taken from Gryffindor house for your cheek, Potter.”

“Is it like a Harry Potter thing?" He turned his head then. "A what?""A Harry Potter thing," she said again. "You know, don't say Voldemort's name because you might attract his attention?"He considered it. "You mean the children's book.""I have got to get you to watch more movies," she said. "You'd enjoy these. Yes, I mean the children's book.”

“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.”

“Famous Harry Potter," said Malfoy. "Can't even go to a bookshop without making the front page.”
