But Dumbledore says he doesn't care what they do as long as they don't take him off the Chocolate Frog cards.

How the fuck are you my dawg when there's no loyalty?

He will never have true friends who is afraid of making enemies.

"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."

Only a fool lets somebody else tell him who his enemy is.

The world will, in the end, follow only those who have despised as well as served it.

The last words Albus Dumbledore spoke to the pair of us?'
Harry is the best hope we have. Trust him.

Let the disloyal then withdraw, let them separate themselves from the loyal. . . . get you gone to your unholy and abominable campaign.

The Irish, above all people in the world, hates a traitor. <small>p. 35</small>

She loathed disloyalty, and there was no greater disloyalty than class betrayal.

This fierce basilisk, this ungrateful, cruel, supercilious wretch, will neither seek, serve, own, nor follow you in any shape whatever.

"I DON'T CARE!" Harry yelled at them, snatching up a lunascope and throwing it into the fireplace. "I'VE HAD ENOUGH, I'VE SEEN ENOUGH, I WANT OUT, I WANT IT TO END, I DON'T CARE ANYMORE!"
"You do care," said Dumbledore. He had not flinched or made a single move to stop Harry demolishing his office. His expression was calm, almost detached. "You care so much you feel as though you will bleed to death with the pain of it."

People are only loyal until it becomes convenient not to be.

I don't care how loyal you think you're going to be, Dink. It's not in you. You're a brat and you always will be. So admit what a lousy follower you are, and go ahead and LEAD.
