“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.”

“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.”

“Harry: This book belongs to Harry Potter. Ron: Shared by Ron Weasley, because his fell apart. Hermione: Why don't you buy a new one then? Ron: Write on your own book, Hermione. Hermione: You bought all those dungbombs on Saturday. You could have bought a new book instead. Ron: Dungbombs rule.”

“Ron, you're making it snow," said Hermione patiently, grabbing his wrist and redirecting his wand away from the ceiling from which, sure enough, large white flakes had started to fall. Lavender Brown, Harry noticed, glared at Hermione from a neighboring table through very red eyes, and Hermione immediately let go of Ron's arm."Oh yeah," said Ron, looking down at his shoulders in vague surprise." Sorry...looks like we've all got horrible dandruff now...."He brushed some of the fake snow off Hermione's shoulder. Lavender burst into tears. Ron looked immensely guilty and turned his back on her."We split up," he told Harry out of the corner of his mouth. "Last night. When she saw me coming out of the dormitory with Hermione. Obviously she couldn't see you, so she thought it had just been the two of us.""ah," said Harry. "Well - you don't mind it's over, do you?" "No," Ron admitted. "It was pretty bad while she was yelling, but at least I didn't have to finish it.""Coward," said Hermione, though she looked amused. "Well, it was a bad night for romance all around. Ginny and Dean split up too, Harry."Harry thought there was a rather knowing look in her eye as she told him that, but she could no possibly know that his insides were suddenly dancing the conga.”

“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.”

“Are — you — insane?” said Hermione in a hushed voice.'I don't think so,' said Harry, shrugging.”
