" Voldemort,” said Riddle softly, “is my past, present, and future, Harry Potter. . . .”
He pulled Harry’s wand from his pocket and began to trace it through the air, writing three shimmering words:
TOM MARVOLO RIDDLE
Then he waved the wand once, and the letters of his name rearranged themselves:
I AM LORD VOLDEMORT "
