“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.”
“Of course we still want to know you!" Harry said, staring at Hagrid."You don't think anything that Skeeter cow - sorry, Professor," he added quickly, looking at Dumbledore."I have gone temporarily deaf and haven't any idea what you said, Harry," said Dumbledore, twiddling his thumbs and staring at the ceiling.”
“He’s gone, Harry told himself. He’s gone. He had to keep thinking it as he washed and dressed, as though repetition would dull the shock of it. He’s gone and he’s not coming back. And that was the simple truth of it, Harry knew, because their protective enchantments meant that it would be impossible, once they vacated this spot, for Ron to find them again.”
“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?”
“But as he reached the ground and sprinted towards the dais, Lupin grabbed Harry around the chest, holding him back.There's nothing you can do, Harry -'Get him, save him, he's only just gone through!'- it's too late, Harry.'We can still reach him -' Harry struggled hard and viciously, but Lupin would not let go...There's nothing you can do, Harry...nothing...he's gone.”
“Dumbledore will only leave from Hogwarts when there are none loyal to him!”
