"Harry. Oh, I'd almost forgotten you were here. Standing on the bones of my father. I'd introduce you, but word has it you're almost as famous as me these days. The Boy-Who-Lived. How lies have fed your legend, Harry! Shall I reveal what really happened that night thirteen years ago? Shall I divulge how I truly lost my powers? Yes, shall I? It was love. You see, when dear, sweet Lily Potter gave her life for her only son, she provided the ultimate protection. I could not touch him. It was old magic. Something I should have foreseen. But no matter, no matter. Things have changed. I CAN TOUCH YOU... NOW! [He places his finger on Harry's forehead lightning bolt scar, and Harry immediately screams out in agony, to Voldemort's cruel delight] Astonishing what a few drops of your blood will do, eh, Harry?"
