Ron: "I know, mate, so it's now or never, isn't it?"
— Harry Potter to Hermione and Ron when they kiss during battle.
5. Hermione: "I told them you'd take it like this."
Harry: "If you think I'm going to let six people risk their lives —!"
Ron: "— because it's the first time for all of us."
6. Ron: "If you're not in Gryffindor, we'll disinherit you. But no pressure!"
Hermione: "Ron! He doesn't mean that..."
7. "To the well-organised mind, death is but the next great adventure."

—Hermione is angry at Draco for happily watching the execution of Buckbeak.

Harry Potter: "Is he — a bit mad?"
Percy Weasley: "Mad? He's a genius! Best wizard in the world! But he is a bit mad, yes."
11. Albus Dumbledore: "Rumours of your doings have reached your old school, Tom. I should be sorry to believe half of them."
Tom Riddle: "Greatness inspires envy, envy engenders spite, spite spawns lies. You must know this, Dumbledore."

Umbridge: "Ah, yes. The time has come for answers, whether he wants to give them or not. Have you bought the Veritaserum?"
Snape: "I'm afraid you have used up all my stores interrogating students [...] Unless you wish to poison Potter - and I assure you, I would have the greatest sympathy if you did - I cannot help you."
17. Dumbledore: "Harry, do you know why...Professor Quirrell couldn't bear to have you touch him? It was because of your mother. She sacrificed herself for you. And that kind of act leaves a mark... This kind of mark cannot be seen. It lives in your very skin."
Harry: "What is it?"

20. “She’ll be in Slughorn’s office,” said Harry confidently, leading the way to the door.
“Why will she be in there?” asked Ron anxiously, hurrying to keep up.

“Great idea,” said Harry.
21. "I'm going to bed before either of you come up with another idea to get us killed, or worse; expelled."

Albus Dumbledore: "But this is touching, Severus. Have you grown to care for the boy, after all?"
23. Dumbledore: "I had proven, as a very young man, that power was my weakness and temptation. I was safer at Hogwarts. I think I was a good teacher."
