“Albus Severus," Harry said quietly, so that nobody but Ginny could hear, and she was tactful enough to pretend to be waving to Rose, who was now on the train, "you were named for two headmasters of Hogwarts. One of them was a Slytherin and he was probably the bravest man I ever knew.”

“I’m never wearing them," Ron was saying stubbornly. "Never."
"Fine," snapped Mrs. Weasley. "Go naked. And, Harry, make sure you get a picture of him. Goodness knows I could do with a laugh.”

“Percy wouldn't notice a joke if it danced naked in front of him wearing one of Dobby's hats.”

“Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. He didn't realize that love as powerful as your mother's for you leaves its own mark. Not a scar, no visible sign… to have been loved so deeply, even though the person who loved us is gone, will give us some protection forever. It is in your very own skin. Quirrel, full of hatred, greed, and ambition, sharing his soul with Voldemort, could not touch you for this reason. It was agony to touch a person marked by something so good.”
