Barty Crouch Junior

"If there's something I hate more than any other, it's a Death Eaterwho walked free. They turned their backs on my master when he needed them most. I expected him to punish them. I expected him to torture them. Tell me he hurt them, Harry.... Tell me he told them that I, I alone remained faithful... Prepared to risk everything to deliver to him the one thing he wanted above all... You."

"Father, I didn't! I didn't, I swear it, Father, don't send me back to the Dementors... No! Mother, no! I didn't do it, I didn't do it, I didn't do it, I didn't know! Don't send me there, don't let him! I'm your son! I'm yourson!"
