"...I will be your living nightmare. I will hunt you to the ends of this earth. You won’t be able to breathe without thinking of me. Behind every corner, you will see my face. I’m free of the imperius curse, I can do what I want now and my only mission in life would be to kill you. And we know I’m better at it now than you are, aunt." He said the word like an insult. "Kill her and you will have created an enemy for a lifetime and I will make sure yours will be short and your death agonizing. You’ll have my word."
