| Quote #7 "Dumbledore told them that their best chance was the Fidelius Charm." |
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.
| Quote #8 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.
| Quote #9 Snape's sallow skin had gone the color of sour milk. |
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.
