Kal, or Clark as he used to be called, would have never expected an attack. He thought that he was doing right by making amends. By fixing every part of damage he had done while here. He was told it was a good step.
So he was understandably in shock when he felt metal fists hitting him from behind, felt a sharp pain as he landed on his back. It was the Batman. He was more in shock that the man actually hit him, than he was about the fact that it had actually hurt. He slowly got back on his feet. "What are you doing, what was that for? If this is about what I said to you.. then I'm sorry. I don't want to fight."
