Lies and Deceit Quotes in Harry Potter and the Prisoner of Azkaban
How we cite our quotes: Chapter.Paragraph or Chapter.Section.Paragraph (depends on whether or not the chapter had sections - some did not)
"Dumbledore told them that their best chance was the Fidelius Charm."
"An immensely complex spell," he said squeakily, "involving the magical concealment of a secret inside a single, living soul. The information is hidden inside the chosen person, or Secret-Keeper, and is henceforth impossible to find – unless, of course, the Secret-Keeper chooses to divulge it." (10.3.147-149)
Like so many of the spells in the Harry Potter books, the Fidelius Charm plays a thematic role. Fidelius is like the word "fidelity," which means loyalty or faith. This is fitting since the charm itself is about much more than just keeping a secret. It's really about loyalty and the decision to keep a secret. The Secret-Keeper can choose to divulge, but as long as that person chooses to stay silent, the secret remains safe.
Why had nobody ever told him? Dumbledore, Hagrid, Mr. Weasley, Cornelius Fudge [...] why hadn't anyone ever mentioned the fact that Harry's parents died because their best friend had betrayed them? (11.1.2)
Themes of betrayal and loyalty are really important in this book. Here, Harry himself feels betrayed by all the adults who committed a lie of omission.
Snape's sallow skin had gone the color of sour milk.
"And did the headmaster tell you the circumstances in which your father saved my life?" he whispered. "Or did he consider the details too unpleasant for precious Potter's delicate ears?" (14.3.78-79)
Once again, Harry's youth is an issue here, as it prevents him from hearing the whole truth about things. Contrast Snape's mean take on Harry's youth to Molly Weasley's protective streak towards "young" Harry earlier in the novel.
