John's face quickly becomes bloodied under the onslaught of Jack's blows, but John laughs insanely the entire time. He quickly grabs Jack's fists and holds them as tightly as he can, then headbutts Jack once to disorient him. John then rolls forward, pinning Jack to the ground, still gripping his hands tightly. John then begins smashing his head into Jack's head, relishing the experience of pain that he doesn't usually feel, due to his powers.
