[i]As Noxx knocked and spoke, suspicious ratcheting and clicking noises would come from the other side of the room, ceasing after a couple seconds. Then, the much anticipated light would flare forth, blinding in its intensity and illuminating the full half of the room it was aimed at. A split second later a brief but even brighter flash would erupt from directly beneath the flash light, the bullet aimed to penetrate right through the machine Nixx was behind with enough kinetic energy left over to put a hole in her center mass, unless stopped by the force field. 

This wasn't the aim of a Stormtrooper. It was the aim of someone that knew how point at a moving target, and unless said target was faster than a bullet, hit it. 
After the shot was fired the light would rotate in a fast circle low to the ground- an obvious barrel roll- and would wind up resting just above a slot machine on Noxx's right. 
If Noxx ducked, she might miss the grenade that would roll to a stop in front if her cover. The pin wouldn't be pulled. 

Unlike her, he'd probably not have his head peaking vulnerably over the top. Regardless, Donny had no idea her weapon could fire through anything. He could certainly work fast though, and with the deftness and slight of hand street magicians utilized. Somehow in between the shot and the roll he'd have managed to loose the grenade, apparently with both hands full. If she noticed the explosive, his plan would be obvious. The first shot meant as a kill, and the grenade as insurance in case the enemy showed any signs of life behind cover.[/i]
