“And now, Harry, let us step out into the night and pursue that flighty temptress, adventure.”
Dumbledore, Half-Blood Prince, Ch. 3
“But while I was at the Dursleys’, I realised I can’t shut myself away or – or crack up. Sirius wouldn’t have wanted that, would he? And anyway, life’s too short … Look at Madam Bones, look at Emmeline Vance … It could be me next, couldn’t it? But if it is, I’ll make sure I take as many Death Eaters with me as I can, and Voldemort too if I can manage it.”
Harry, Half-Blood Prince, Ch. 4
“Spoken like your mother and father’s son and Sirius’s true godson! I take my hat off to you — or I would, if I were not afraid of showering you in spiders.”
Dumbledore, Half-Blood Prince, Ch. 4
“Very well, then. I see a light in the kitchen. Let us not deprive Molly any longer of the chance to deplore how thin you are.”
Dumbledore, Half-Blood Prince, Ch. 4
“Naturally I do [think I'm right], but as I have already proven to you, I make mistakes like the next man. In fact, being — forgive me — rather cleverer than most men, my mistakes tend to be correspondingly huger.”
Dumbledore, Half-Blood Prince, Ch. 10
“I can make things move without touching them. I can make animals do what I want them to do, without training them. I can make bad things happen to people who annoy me. I can make them hurt if I want to.”
Young Tom Riddle, Half-Blood Prince, Ch. 13
“Did I know that I had just met the most dangerous Dark wizard of all time? No, I had no idea that he was to grow up to be what he is. However, I was certainly intrigued by him. I returned to Hogwarts intending to keep an eye upon him, something I should have done in any case, given that he was alone and friendless, but which, already, I felt I ought to for others’ sake as much as his.”
Dumbledore, Half-Blood Prince, Ch. 13
“You will hear many of his Death Eaters claiming that they are in his confidence, that they alone are close to him, even understand him. They are deluded. Lord Voldemort has never had a friend, nor do I believe that he has ever wanted one.”
Dumbledore, Half-Blood Prince, Ch. 13
“It looks like he’s eating her face, doesn’t it? But I suppose he’s got to refine his technique somehow.”
Ginny [about Ron], Half-Blood Prince, Ch. 14
“Yes, he’s a vampire [Scrimgeour]. Father wrote a very long article about it when Scrimgeour first took over from Cornelius Fudge, but he was forced not to publish by somebody from the Ministry. Obviously, they didn’t want the truth to get out!”
Luna, Half-Blood Prince, Ch. 15
