Gena doesn't think twice when she slides the pistol across to Emma. Shane isn't looking, and what would he say anyway? He wasn't the one threatened, handed over as a prize to be raped and tortured.
Emma looks down as Mother nudges her hand with the butt. Mauser is on his knees praying, they have time before the missile strike, and no one's paying attention.
She always wondered why her father said learning to shoot was a good idea. Now, Emma knows.
Fragments of his skull and brain matter splatter over the concrete. Blood spatter coats her face and clothes in a fine mist, leaving her to blink away the emotional indifference. Killing Mauser is no harder than putting down an injured animal.
