At the time it seemed so cut and dry. When the old man held out the knife and asked him to kill the kid, Dave didn't think twice. The man was clearly nuts. Raving about an apocalypse that only the boy's death could stop. Dave had done what any rational person would have - knocked the lunatic out. A lucky punch and all had been over... or so he thought. Locked in a skyscraper in Melbourne, Dave Thomas has ample time to rue and lament his decision. As he watches the city burn, it's a little difficult to escape the enormity of his mistake. Claws have invaded the shadows. Billions are dead. Continents in ruin. And to rub salt in the wounds, the only hope for salvation is to face that decision all over again. He really should have killed the kid.
