Sorry about the double post, I forgot to put a note at the beginning. This is a very very short little one-shot snippet. It was inspired by Star Wars and too many HarryxVoldemort pairings.
"Crucio!" Lord Voldemort hissed with a crazed glint in his eyes. This was the moment he was waiting for. Harry Potter, savior of the wizarding world, the Boy-Who-Was-About-To-Feel-His-True-Wrath, was writhing in pain at his feet. Excellent.
"Did you enjoy that, Potter?" There was mostly silence coming from the broken figure, aside from the occasional whimper. This was perfect. Now Voldemort could reveal his long-kept secret, and cause the boy even more pain. He smirked evilly, in a way that only a true Slytherin could.
"I have something to tell you, Harry Potter." The boy slightly raised his head, enough for Voldemort to see his green eyes. The Dark Lord could not read the emotions that poured out of them, but he decided he didn't need to.
"I am your father, Harry."
Instead of the protests of "No! No! That's not true. That's impossible!" that Voldemort had expected, the boy merely sighed.
"Well damn," he coughed out weakly, "I don't suppose you're one for incest?"
Voldemort twitched.
"AVADA KEDAVRA!"
