“Hmm,” said a small voice in his ear. “Difficult. Very difficult. Plenty of courage, I see. Not a bad mind either. There’s talent, oh my goodness, yes — and a nice thirst to prove yourself, now that’s interesting. . . . So where shall I put you?”Harry gripped the edges of the stool and thought, Not Slytherin, not Slytherin.“Not Slytherin, eh?” said the small voice. “Are you sure? You could be great, you know, it’s all here in your head, and Slytherin will help you on the way to greatness, no doubt about that — no? Well, if you’re sure — better be GRYFFINDOR!”

“You could be great, you know, it’s all here in your head, and Slytherin will help you on the way to greatness, no doubt about that.”

“You will find ambiguity a great ally on your road to power. Give a sign of Slytherin on one day, and contradict it with a sign of Gryffindor the next; and the Slytherins will be enabled to believe what they wish, while the Gryffindors argue themselves into supporting you as well. So long as there is uncertainty, people can believe whatever seems to be to their own advantage. And so long as you appear strong, so long as you appear to be winning, their instincts will tell them that their advantage lies with you. Walk always in the shadow, and light and darkness both will follow.”

“If this was Harry Potter, he'd definitely be in Slytherin”

“But if it matters to you, you'll be able to choose Gryffindor over Slytherin. The Sorting Hat takes your choice into account.""Really?""It did for me," said Harry.He had never told any of his children that before, and he saw the wonder in Albus's face when he said it.”

“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.”
