4-Dark

Darkness is a friend to some, and a deep enemy to others. Mariano had learned this over the years, how to make himself melt away into it, or to use to reappear across the room. Darkness was a close friend, and one that he dare not betray. That is what brought him here, he was driven by darkness, it was slowly draining away his control, until soon he would be nothing, nothing but the darkness that he had found so comforting. He pulled out his loaded pistol, and shifted through the shadows. The house was dull, white walls, brown furniture, old lamps. Most surely it was the home of an elderly person, but he didn't care, he was being driven by the darkness. He heard a door crack open, and he instantly stilled. A older man, probably of the age of seventy, though seeming remarkably healthy walked through the hall, right past him. He slowly reached down, drew his pistol and aimed it non-chalantly at the back of the man's head. It was so easy, just the pull of the trigger, and he could melt all the deeper into his friend, and hide amongst him like a bird among bushes. It would not accept him, if he did not continue to serve its will. He felt his finger on the cold trigger slowly begin to squeeze, pushing the life out of the old man. Until he was hit by visions. He saw a fountain of blood, the man rising out of it, basking in it. He slowly raised himself out of it, and began to crawl toward Mariano, leaving a trail of blood in his wake. Mariano froze, and felt the gun begin to slip from his grip, "What have I become?" and collapsed on the floor.

"Is he alright?" Jerry asked, pointing to where the man now known as Mariano lay on a hospital bed.
The doctor looked at him, "I'm afraid not, something, we can't figure out what, seems to be stifling his breathing. It happens in the night, and we are afraid he could be near the end."
The room began to darken as the Texan sun set over the horizon. They watched for a little bit, watching the near murderer, or at least as far as they knew. The sun set across the room, in beautiful spectrum colors, but when it disappeared, the man began to convulse.
"CODE RED! CODE RED!" The doctor yelled as he ran to the man. Just then, and the man went still, the doctor felt his pulse.
"He's dead."
