Mac would notice Thistle getting out of the way and turned his head, noticing the draconic coming right for him. The uselessness of the rifle, Thistle eating his teammates and somehow infatuating him, and the shrinking of the tazer got to him. It probably was a mistake to look away from his target, but he didn't really care about anything now. He gripped his rifle and smacked Wil in the face with the butt of his gun. If he didn't drop like a stone, he hoped that Kine would get there and help him out.
