Hermione: ".. I've read the whole book."
Dolores Umbridge: "Well then you should be able to tell me what Slinkhard thinks about Counter-Jinxs in Chapter Fifteen.."
Hermione: "He says that counter-jinxes are improperly named. He says "counter-jinx" is just a name people give their jinxes when they want to make them sound more acceptable. But I disagree... Mr. Slinkhard doesn't like jinxes, does he? But I think they can be very useful when they're used defensively..."
Dolores Umbridge: "Oh you do, do you? Well, I'm afraid thats it is Mr. Slinkhards opinion and not yours, that matters within this classroom, Mrs. Granger."
