“Harry constantly repeated Dumbledore's final words to himself. "I will only truly have left this school when none here are loyal to me. ... Help will always be given at Hogwarts to those who ask for it. "But what good were these words? Who exactly were they supposed to ask for help, when everyone was just as confused and scared as they were?”
“Such loyalty is admirable, of course,” said Scrimgeour, who seemed to be restraining his irritation with difficulty, “but Dumbledore is gone, Harry. He’s gone.”“He will only be gone from the school when none here are loyal to him,” said Harry, smiling in spite of himself.”
“However, you will find that I will only truly have left this school when none here are loyal to me. You will also find that help will be given at Hogwarts to those who ask for it.”
“You can try, but you seem cleverer than Fudge, so I'd have thought you'd have learned from his mistakes. He tried intervening at Hogwarts. You might have noticed he's not Minister anymore, but Dumbledore's still headmaster. I'd leave Dumbledore alone, if I were you.”
