As the unnamed assailant slides forward off of Jack's blade and crumples wordlessly to the ground, his killer's white-knuckle grip on his weapon loosens. The sudden cessation of fighting grunts and clashing steel tells Jack that the battle is over, and a quick glance reveals that his own allies still stood.
That's good, he supposes.
His gaze shifts downward to the last man he'd put an end to, his lips tightening in a somewhat pitying frown. The dripping of blood from the point of Jack's weapon catches his eyes, and Jack slowly crouches beside the blood's source. He wipes the blade on an unsullied portion of clothing, once for either side of the steel. He checks the sheen in the moonlight before wiping twice more, finally satisfied with the process after the second attempt.
While battle gives way to bargaining nearby, Jack begins to search the bodies. Selfishly, for valuables that they'd no longer need. Unselfishly, for signs of who they were and why they'd attacked.
Eventually, he chimes into the debate. "At my last job, there was a guard who would take something from anyone who snuck into the show until they paid up, with interest. Two parents snuck in with a kid once, guard kept the kid in an empty bear cage until the parents worked off their debt. Not exactly the same situation here, but this survivor would serve us better as a bargaining chip, in case there're any more like him out there."
