Khrev is a more serious guard, but was dragged down the ranks trying to "help" his "buddy" Caleb. Although serious, he is somewhat still lazy at times. Just imagine your most annoying friend next ti you, you want them to shut up, they never did when you first met, and you're so done that you just have to tolerate it. Maybe even an annoyed father telling his child for the hundredth time that he's not getting the toy. His voice range should be medium to low.
