James was silent in his obedience of the Inquisitor's overwatch command. It was a simple order: take a vantage point and set up, rifle at the ready. Which was extremely easy considering the variety of buildings available to him for cover, it did not take him long to find a proper point to take cover from. Soon he was set up with his rifle mounted in a small window of an empty apartment that he crawled into. The window gave enough of a view that he could see the Gallery clearly. His breathing was slight and controlled, reducing scope sway, the second he could no longer follow the group he began scanning the area for suspicious personnel, if he saw anyone coming in or out of the facility. If anything would come through, a silent signal would be sent to the Inquisitor to warn him. Right now he needed to be ready and sharp, as at any moment James's skill could be put to the ultimate test against any kind of heretical foe. So his scope scanned every face, every window, and anything in between were a person could do recon on the Gallery or the people inside it.
As long as the Inquisitor needed him and his rifle, they were ready to kill, tonight was no different. Tomorrow would not be either, for the Emperor and his people, the heretics shall fall by his shots. Glory to the Imperium, and honor to the Inquisitor.
