[Riddick is at less of a disadvantage. He coexists alongside his instincts; he's never masked them. He bends-- the blow to kneecap bruises his thigh instead, the shiv scores the top of his bicep instead of plunging in, and he moves past these pains to make a stiff-armed grab for Hannibal's throat. The smell of blood makes him hiss as much as the pain.]
