“Anyway, members of the Inquisitorial Squad do have the power to dock points so, Granger, I'll have five from you for being rude about our new Headmistress. Macmillan, five for contradicting me. Five because I don't like you, Potter. Weasley, your shirt's untucked, so I'll have another five for that. Oh yeah, I forgot, you're a Mudblood, Granger, so ten off for that.”
“That is the second time you have spoken out of turn, Miss Granger,” said Snape coolly. “Five more points from Gryffindor for being an insufferable know-it-all.”
“Miss Granger, you foolish girl, how could you think of tackling a mountain troll on your own? Five points will be taken from Gryffindor for this,” said Professor McGonagall. “I’m very disappointed in you.”Hermione left. Professor McGonagall turned to Harry and Ron.“Well, I still say you were lucky, but not many first years could have taken on a full-grown mountain troll. You each win Gryffindor five points.”
“Another ten points from Gryffindor,” said Snape. “I would expect nothing more sophisticated from you, Ronald Weasley, the boy so solid he cannot Apparate half an inch across a room.”
“I think I'd better do the actual stealing," Hermione continued in a matter-of-fact tone. "You two will be expelled if you get into anymore trouble, and I've got a clean record. So all of you need to do is cause enough mayhem to keep Snape busy for five minutes or so.”
“You look in excellent health to me, Potter, so you will excuse me if I don't let you off homework today. I assure you that if you do die, you need not hand it in.”
“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.”
