Diamonds and Spades

Prologue

Ace could feel the power bubbling up at his fingertips. This time he could do it. Second time was always the charm. Skid marks from when he had tried to travel back in time the last time were still on the floor and his body was heavily bruised from running into the wall. But yet he ran at it again.
The travel made his stomach twist in knots but he made it. He landed in the past. He could already feel his powers fading but he could do it.
       Ace was there. He heard the sudden bang behind him as his powers dissipated. Then a gang member edged it's way toward him. His blade and eyes were sharp and his weapon was coated in dark blood. It wasn't fresh by any means, but it was still rather unnerving.
     Then he rushed at Ace. Ace was familiar with this tactic having tried it a few times himself. Without thinking Ace pulled out his revolver. And within seconds the gang member had a bullet steadily planted in his stomach. He toppled over and his head landed on the barrel of Aces pistol.
      Aces finger traced the trigger as he thought about pulling it. He saw the man's beady eyes look up and Ace saw sorrow. This man had a life in front of him. Sadly, it was a life as a gang member. When Ace thought of this it didn't take a second of hesitation. The bullet pierced through the back of the man's head, leaving a gory hole.
      Ace ran. He knew that this wasn't the apocalypse anymore. That wasn't just survival now. People would consider it cold-blooded murder. He knew people were chasing after him. Their screams and the repetitive pounding of footsteps followed shortly behind him. Ace saw the colosseum in front of him. If he could make it, survival had a better chance. It wasn't certain. It never would be in the past. Ace wasn't the hero anymore. Now he was a murderer.
