John had heard the scream, yet it didn't matter at the moment, as he already started a fight of which he can not back down from. John had run up to the man and throwing a right hook to his jaw. It would not be a jump, but more of a run-up. The way he executed the punch was with a run up with until he was within range. The punch would likely send him flying, with John being able to survive the pressure of the ocean, he had become one strong fella.
