How we cite our quotes: Chapter.Paragraph or Chapter.Section.Paragraph (depends on whether or not the chapter had sections - some did not)
Quote #4
Unless Harry's eyes were deceiving him, Fudge was suddenly looking awkward.
"Circumstances change, Harry [...] We have to take into account [...] in the present climate [...] Surely you don't want to be expelled?" (3.137-138)
For a politician, Fudge is a pretty lousy liar. We can't decide whether to give him props for that or not. Stylistically, the pauses between Fudge's phrases, and his inability to complete a sentence, demonstrate his awkwardness.
Quote #5
"Harry's got a right to know. I've tried to tell Fudge, but he insists on treating Harry like a child. He's thirteen years old and –"
"Arthur, the truth would terrify him!" said Mrs. Weasley shrilly. (4.3.25-26)
Arthur Weasley really ties the theme of truth to themes of childhood here. Throughout this book, truth is associated with being an adult – you have to be old enough to hear certain things.
Quote #6
"You haven't got any of these subjects today. It's only Defense Against the Dark Arts this afternoon."
"Oh yes," said Hermione vaguely, but she packed all the books into her bag just the same.
[...]
"D'you get the feeling that Hermione's not telling us something?" Ron asked Harry. (7.1.82)
Cool character detail alert – Hermione never actually lies about her Time-Turner. She instead opts to change the subject, give a vague response, or just remain silent.
