The moment Scott started rolling, Alex was dropping out of the tree. As he strode towards the wolf laying on the ground, he pulled off his helmet and shrugged out of the top half of his ghillie suit, letting both fall to the ground. It was only as he got close, and as Scott was helpfully rolling over and sitting up, that he pulled the short sword from the scabbard strapped to his back.
"I'd tell you to pray for salvation, but everyone knows that dogs don't go to heaven," Alex said, just before he brought the sword down swiftly, removing Scott's head from his body.
And if he kicked the teen's head away from the body like a soccer ball just for the hell of it, no one needed to know.
