12. Rage

It was happening again, just like all those years ago. It churned and bubbled inside of him, festering like poison that consumed him and robbed him of his sanity. Nothing else registered in his mind. All he could see was the Gorn holding Teddy captive, a crude makeshift blade to his throat. His son was pale, his hair still white while eyes begged for help, fear obvious within their depths.

He had been caught off guard. They were running and it was only a split second too late that Harry became tangled in some vines that had been laid out in the middle of the path. The vine was connected to netting which triggered a few large rocks to fall onto him. Luckily they merely pinned his legs rather than crushing or breaking them. He was also thankful Teddy was unharmed. Yet before he could move the rocks, they heard the hissing of the Gorn nearby. Harry had ordered Teddy to run and hide, wishing for him to be safe. He had been stubborn at first, but complied in the end and rushed off.

Using Wingardium Leviosa to levitate the rocks, Harry managed to pull himself out and heal his injuries. When he was able to walk, Harry had quickly worked to locate his son although hearing his scream had shot terror through him. And that's how he found himself in his current predicament.

Clamping onto the fiery anger curling inside of him, Harry hissed out, "Release my son or you will find yourself in for a world of pain." The Gorn merely pressed the blade tighter to Teddy's vulnerable throat as if daring him to attack. A single cut formed, blood beading to the surface before rolling down in a tear. Something snapped.

"Accio dagger!" Harry shouted. As commanded the dagger flew into his hand, the movement surprising the Gorn enough to loosen his hold on Teddy. The small boy took advantage of the weakness and slipped away rushing to hide behind a boulder. The Gorn snarled in rage before the voice of his opponent cried out, "Immobulus!"

Harry watched as the Gorn froze and fell over, its body bound and unable to move. Walking over slowly, he appeared very much like a predator stalking his prey. His hair was fluttering as his magic rolled off of him in waves, his eyes glowing with power yet their depths were cold and unforgiving. Raising his fingers again, he hissed, "Crucio!"

The Gorn couldn't even scream, it merely twitched and withered in pain. A dark, vile blackness crept in Harry's mind, hissing and purring to him. He felt a twisted satisfaction in watching this creature flail in pain, to know he had the power to make it bend to his will.

After all, it had hurt his son and threatened their lives. It along with its people had killed off innocent civilians. They all deserved pain, deserved to feel withering agony for their sins. The voice, so familiar and vile, hissed in agreement. It cooed to Harry, whispering more dark words and suggestions. It told him to torture the Gorn, to kill it and the rest of its race. They were filth and didn't deserve to live. They didn't deserve life!

"Dad! Stop it! Dad please! DAD!"

Harry jumped his concentration gone, breaking the spell. Green eyes glanced down to see Teddy clinging to him tightly as if to physically restrain him, sobbing into his uniform. Dazed, he looked to the Gorn who was twitching, but still alive. The implication of what he had just done hit him like a sledge hammer and it took all his will not to vomit. Yet he could feel the bile at the back of his throat, his stomach churning in disgust.

Falling to his knees, Harry clutched Teddy to himself and buried his face into his son's hair, his shoulders shaking as he began to cry. It was unforgiveable what he had just done. He had used a curse that he despised with all his soul, a curse that had robbed one of his old friend's his parents. And he had liked it.

He had felt such wicked, sinister emotions; such glee and satisfaction in the power it gave him. To know that he held a life within his hand, that he held power over the Gorn. For a moment, that same dark voice spoke to him and mocked him; the voice of the man who had stolen everything from him. It whispered that now they were the same, two sides of the same coin and Harry cried harder.

Please review! Thanks!
