“Dumbledore had not raised his voice, he did not even sound angry, but Harry would have preferred him to yell; this cold disappointment was worse than anything.”
“But somebody else had spoken Snape’s name, quite softly.“Severus . . .”The sound frightened Harry beyond anything he had experienced all evening. For the first time, Dumbledore was pleading.Snape gazed for a moment at Dumbledore, and there was revulsion and hatred etched in the harsh lines of his face.“Severus . . . please . . .”Snape raised his wand and pointed it directly at Dumbledore. “Avada Kedavra!”A jet of green light shot from the end of Snape’s wand and hit Dumbledore squarely in the chest. Harry’s scream of horror never left him; silent and unmoving, he was forced to watch as Dumbledore was blasted into the air. For a split second, he seemed to hang suspended beneath the shining skull, and then he fell slowly backward, like a great rag doll, over the battlements and out of sight.”
“It's going to be all right, 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.”
“He felt even angrier that Dumbledore was showing signs of weakness. He had no business being weak when Harry wanted to rage and storm at him.”
“He accused me of being Dumbledore's man through and through.""How very rude of him.""I told him I was."Dumbledore opened his mouth to speak and then closed it again. Fawkes the phoenix let out a low, soft, musical cry. To Harry's intense embarrassment, he suddenly realized that Dumbledore's bright blue eyes looked rather watery, and stared hastily at his own knee. When Dumbledore spoke, however, his voice was quite steady. "I am very touched, Harry.”
“At that moment, Harry fully understood for the first time why people said Dumbledore was the only wizard Voldemort had ever feared. The look upon Dumbledore's face as he stared down at the unconscious form of Mad-Eye moody was more terrible than Harry could have ever imagined. There was no benign smile upon Dumbledore's face, no twinkle in the eyes behind the spectacles. There was cold fury in every line of the ancient face; a sense of power radiated from Dumbledore as though he were giving off burning heat.”
