"Albus Severus," Harry said quietly, so that nobody but Ginny could hear, and she was tactful enough to pretend to be waving to Rose, who was now on the train, "you were named for two headmasters of Hogwarts. One of them was a Slytherin and he was probably the bravest man I ever knew."
— J.K. Rowling (Harry Potter and the Deathly Hallows)

"It was, he thought, the difference between being dragged into the arena to face a battle to the death and walking into the arena with your head held high. Some people, perhaps, would say that there was little to choose between the two ways, but Dumbledore knew - and so do I, thought Harry, with a rush of fierce pride, and so did my parents - that there was all the difference in the world."
— J.K. Rowling (Harry Potter and the Half-Blood Prince)

"Death's got an Invisibility Cloak?" Harry interrupted again.
"So he can sneak up on people," said Ron. "Sometimes he gets bored of running at them, flapping his arms and shrieking . . ."
— J.K. Rowling (Harry Potter Boxset Books 1-7)

"I DON'T CARE!" Harry yelled at them, snatching up a lunascope and throwing it into the fireplace. "I'VE HAD ENOUGH, I'VE SEEN ENOUGH, I WANT OUT, I WANT IT TO END, I DON'T CARE ANYMORE"
"You do care," said Dumbledore. He had not flinched or made a single move to stop Harry demolishing his office. His expression was calm, almost detached. "You care so much you feel as though you will bleed to death with the pain of it."
— J.K. Rowling (Harry Potter and the Order of the Phoenix)

"You could say sorry," suggested Harry bluntly.
"What, and get attacked by another flock of canaries?" muttered Ron.
"What did you have to imitate her for?"
"She laughed at my mustache!"
"So did I, it was the stupidest thing I've ever seen."

"Ah" said Dumbledore gently, "Yes I thought we might hit that little snag!"
"Snag?" said Fudge, his voice still vibrating with joy. "I see no snag, Dumbledore!"
"Well," said Dumbledore apologetically, "I'm afraid I do."
"Oh, really?"
"Well it's just that you seem to be labouring under the delusion that I am going to -- come quietly. I am afraid I am not going to come quietly at all, Cornelius. I have absolutely no intention of being sent to Azkaban. I could break out, of course -- but what a waste of time, and frankly, I can think of a whole host of things I would rather be doing."
— J.K. Rowling (Harry Potter and the Order of the Phoenix)

"It's going to be alright sir," Harry said over and over again, more worried by Dumbledore's silence than he had been by his weakened voice. "We're nearly there ... I can Apparate us both back ... don't worry ..."

"I am not worried, Harry," said Dumbledore, his voice a little stronger despite the freezing water. "I am with you."
— J.K. Rowling (Harry Potter and the Half-Blood Prince)

"Give her hell from us, Peeves."
— J.K. Rowling (Harry Potter and the Order of the Phoenix)

"Well?" Ron said finally, looking up at Harry. "How was it?"
Harry considered it for a moment. "Wet," he said truthfully.
Ron made a noise that might have indicated jubilation or disgust, it was hard to tell.
"Because she was crying," Harry continued heavily.
"Oh," said Ron, his smile faded slightly. "Are you that bad at kissing?"
"Dunno," said Harry, who hadn't considered this, and immediately felt rather worried. "Maybe I am."
"Of course you're not," said Hermione absently, still scribbling away at her letter.
"How do you know?" said Ron in a sharp voice.
"Because Cho spends half her time crying these days," said Hermione vaguely. "She it at mealtimes, in the loos, all over the place."
"You'd think a bit of kissing would cheer her up," said Ron grinning.
"Ron," said Hermione in a dignified voice, dipping the point of quill into her ink pot, "You are the most insensitive wart I have ever had the misfortune to meet."
"What's that supposed to mean?" Ron asks indignantly. "What sort of person cries while someone's kissing them?"
"Yeah," said Harry, slightly desperately, "Who does?"
Hermione looked at the two of them with an almost pitying expression on her face.
"Don't you understand how Cho's feeling at the moment?" she asked.
"No," said Harry and Ron together.
Hermione sighed and laid down her quill.
"Well, obviously, she feels very sad, because of Cedric dying. Then I expect she is feeling confused because she liked Cedric and now she likes Harry, and she can't work out who she likes best. Then she'll be feeling guilty, thinking it's an insult to Cedric's memory to be kissing Harry at all, and then she'll be worrying about what everyone else might say if she starts going out with Harry. And she probably can't work out what her feelings towards Harry are anyway, because he was with Cedric when he died, so that's all very mixed up and painful. Oh, and she is afraid she is going to be thrown off the Ravenclaw Quidditch team because she's been flying so badly."
A slightly stunned silence greeted the end of this speech, then Ron said, "One person can't feel all that at once, they'd explode."
"Just because you've got the emotional range of a teaspoon doesn't mean we all have," Hermione said nastily, picking up her quill again."

"You'd think people had better things to gossip about," said Ginny as she sat on the common room floor, leaning against Harry’s legs and reading the Daily Prophet. "Three Dementor attacks in a week, and all Romilda Vane does is ask me if it’s true you’ve got a Hippogriff tattooed across your chest."
Ron and Hermione both roared with laughter. Harry ignored them.
"What did you tell her?"
"I told her it's a Hungarian Horntail," said Ginny, turning a page of the newspaper idly. "Much more macho."
"Thanks," said Harry, grinning. "And what did you tell her Ron’s got?"
"A Pygmy Puff, but I didn’t say where."
— J.K. Rowling (Harry Potter and the Half-Blood Prince)
