Chapter One: The Truth Is Revealed

Harry stood silently in the hallway outside the Headmaster's office. Professor McGonagall had told him that Dumbledore wished to speak to him. About what, Harry did not know.

The door that lead into the Headmaster's office opened, and Harry's new Defense Against the Dark Arts teacher, Remus Lupin appeared. Harry was just starting his third year at Hogwarts, but he already liked Lupin. He had helped Harry on the Hogwarts Express and he was a real nice guy. Harry just hoped that Lupin wouldn't turn out to be a dark wizard and try to kill him, or an arrogant, conceited git like the Defense teacher the year before.

"Come on in Harry," Lupin said warily. Harry followed him into the elegant office. Much to Harry's dislike, his most hated teacher, Severus Snape was sitting in a chair across from Albus Dumbledore. To Harry's surprise, Snape's face did not hold his infamous sneer that Harry was now growing quite use to. Instead his face was completely neutral, showing not even a flicker of emotion.

"I- Is anything wrong Professor?" Harry asked nervously, his eyes now on Dumbledore.

"No Harry, but I do have some important news that has just come to my attention, and I feel you have every right to know what it is," he said calmly as his eyes slowly drifted to Snape and quickly snapped back onto Harry. "Harry, I think it would be best if you would sit down…" The Headmaster said slowly.

Harry walked to the armchair beside Professor Lupin and seated himself abruptly. "What is it Professor?" Harry asked worriedly.

Dumbledore closed his eyes for a moment before saying, "Harry… James Potter isn't your real father."
