Hermione Granger

"I do hope you're planning to die, Harry, because if not, you're heading straight for a Muggle hospital."

"It's not who you are underneath, but what you do that defines you."

"Fear of a name only increases fear of the thing itself."

"Books are a uniquely portable magic."

"One can never have enough socks."

"The truth is like a lion; you don't have to defend it."

"Honestly, don't you two read? Hogwarts: A History is quite clear on this."

"It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived."

"Hermione, you're a lifesaver!"

"I'm sorry, but I care about the rules."

"No, I don't need to rest! I don't rest. I plan."

"Wizards have more power than muggles, and it's our job to think about how we use it."

"I know this is probably a terrible time to mention it, but you're a parselmouth."

"Someone's got to go and have more sense than to run down the Middle of the forest at night!"

"I'm going back to school, nothing's stopping me."

"The library is the most important place in the castle."

"Do you know how many house-elves work in kitchens across the country?"

"I spent the whole summer studying ancient runes."

"Just because it's not in your textbook doesn't mean it's not real."

"There's nothing in the rulebook saying a house-elf can't be freed."

"Honestly, you'd think you'd never been to Diagon Alley before."

"I know everything is scary right now, but we have to be brave."

"Knowledge is power, and power should be used wisely."

"Three points lost for Gryffindor? That's terrible!"

"Honestly, I'm not entirely sure what I've got here."

"I can't believe how they've been treating the house-elves."

"You've got to trust your instincts sometimes."

"We just have to make the best of it."

"I'm not trying to be difficult, I'm just trying to be thorough."

"The important thing is that you tried."
