Do you know why I survived, professor, the night I got this. Because of her, because she sacrificed herself, because she refused to step aside, because her love was more powerful than Voldemort. Don't say his name. I'm not afraid of the name, professor. I'm going to tell you something, something others have only guessed at, it's true, I am the chosen one. Only I can destroy him, but to do so I need to know what Tom Riddle said to you all those years ago in your office, and I need to know what you told him. Be brave, professor, be brave like my mother. Otherwise, you disgrace her, otherwise she died for nothing.
