Boom!
The attack died down and both Grey and the young man came into view. They were both standing in the same spot as before, staring dead at each other. Now, the young man didn't exude the level of confidence he did at the start of the battle.
From their short exchange, he knew there was no way he would be able to kill Grey. He had to defeat Grey first before he should even think of killing him.
Grey was also staring at the young man, multiple thoughts running through his head. He knew this was not the full strength of the young man standing before him, but he was also confident that he would be able to defeat him.
Also, he didn't want to show his full card, he still had to think of a way to kill the young man who attacked him the last time. If he were to go up against that young man, he wanted to use his full strength to kill him in a single attack.
