It was only after hearing Jaden's question that finally, John came back to his senses. Considering that the fight had just happened close to the car, he was able to make out a few things.
At first, it was that guy who had been launched flying by just a single attack from Jaden. Then in the next moment, there was a scream that came from a distance away.
John obviously did not understand the reason of the scream, but he believed that it was clear that Jaden was involved. As for the method that was used to attack, did John even need to think about it? Jaden was a mutant, and it was clear that it was not impossible for him to be able to attack from a distance, right?
Then in the next moment, just before the scream, John was able to tell that there was a figure that was approaching. He did not notice when it approached, but he only noticed that there was a figure that had suddenly appeared in front of Jaden.
