The Supernatural Quotes in Harry Potter and the Half-Blood Prince

How we cite our quotes: (chapter.paragraph)

Quote #4

Hermione had managed to squeeze through to a large display near the counter and was reading the information on the back of a box bearing a highly colored picture of a handsome youth and a swooning girl who were standing on the deck of a pirate ship.

"One simple incantation and you will enter a top-quality, highly realistic, thirty-minute daydream, easy to fit into the average school lesson and virtually undetectable (side effects include vacant expression and minor drooling." (6.95-96)

Even Hermione, the one who knows everything and who is cautious about much in life, can't help but be lured in by the promise of a love potion. The fact that magic can interfere with love seems troubling to us considering all of the emotions that get tied up with falling in love. What happens when people take love potions in this story?

Quote #5

"That's right….Well, we thought Shield Hats were a bit of a laugh, you know, challenge your mate to jinx you while wearing it and watch his face when the jinx just bounces off. But the Ministry bought five hundred for all its support staff! And we're still getting massive orders!" (6.112)

The fact that the Ministry of Magic is buying supplies from Fred and George's joke shop does not inspire the greatest of confidence in us. Seriously, though, the Ministry of Magic is supposed to be very powerful and full of all kinds of information. This fact tells us a lot about the state of affairs in the magical headquarters. Things must not be good. Fred and George show us another side of magic: its playful, silly, and prankster side. Yet, we also know that when mixed with the wrong kind of magic, even this playful magic can be dangerous.

Quote #6

"The Dark Arts," said Snape, "are many, varied, ever-changing, and eternal. Fighting them is like fighting a many-headed monster, which, each time a neck is severed, sprouts a head even fiercer and cleverer than before. You are fighting that which is unfixed, mutating, indestructible." (9.55)

Has Harry ever encountered Dark Magic that proved Snape's point right? Has he ever fought something that was like fighting a "many-headed monster"?
