Dumbledore's man through and through, aren't you Potter?"
"Yeah I am," said Harry. "Glad we straightened that out.

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.

Harry - you're a great wizard, you know."
"I'm not as good as you," said Harry, very embarrassed, as she let go of him.
"Me!" said Hermione. "Books! And cleverness! There are more important things - friendship and bravery and - oh Harry - be careful!

We are all in the same boat in a stormy sea, and we owe each other a terrible loyalty.
