“But this is touching, Severus,” said Dumbledore seriously. “Have you grown to care for the boy, after all?”
“For him?” shouted Snape. “Expecto Patronum!”
From the tip of his wand burst the silver doe. She landed on the office floor, bounded once across the office, and soared out of the window. Dumbledore watched her fly away, and as her silvery glow faded he turned back to Snape, and his eyes were full of tears.
“After all this time?”
“Always,” said Snape.”

“Have you ever seen anything quite as pathetic?" said Malfoy. "And he’s supposed to be our teacher!"
Harry and Ron both made furious moves toward Malfoy, but Hermione got there first - SMACK!
She had slapped Malfoy across the face with all the strength she could muster. Malfoy staggered. Harry, Ron, Crabbe, and Goyle stood flabbergasted as Hermione raised her hand again.
"Don’t you dare call Hagrid pathetic you foul—you evil—"
"Hermione!" said Ron weakly and he tried to grab her hand as she swung it back.
"Get off Ron!"
Hermione pulled out her wand. Malfoy stepped backward. Crabbe and Goyle looked at him for instructions, thoroughly bewildered.
"C’mon," Malfoy muttered, and in a moment, all three of them had disappeared into the passageway to the dungeons.
"Hermione!" Ron said again, sounding both stunned and impressed.”

“Harry — I think I've just understood something! I've got to go to the library!”
And she sprinted away, up the stairs.
“What does she understand?” said Harry distractedly, still looking around, trying to tell where the voice had come from.
“Loads more than I do,” said Ron, shaking his head.
“But why’s she got to go to the library?”
“Because that’s what Hermione does,” said Ron, shrugging. “When in doubt, go to the library.”
