While Ennis heaved, Jack crouched to the ground, hovering, hoping the other man would let him know what he could do to help. When he saw the look, he made up his mind, deliberately crawling over to Ennis, taking him in another embrace. Any resistence to the touch would be met with as much strength as Jack had, an attempt to wrestle the man on his knees back to the wall. To do a bit of dominating of his own, to show Ennis Jack needed this just as bad as he did.
