Clark would have easily been able to dodge or catch the sailing mug if not for the fact that Lois had surprised him. Once second she was all calm and collected, the next she was hurling his mug at him? It slammed into his shoulder and immediately shattered, the impact very much turning out to be similar to one throwing a glass at a rock wall. Looking down at the ruins of his mug, Clark took a step to the side in case he needed to dodge another flying object. One hand rose to brush the bits and pieces of broken mug from his shirt as he looked across the room at Lois in concern.
"You didn't have to throw that," he pointed out. At least he was getting some kind of emotion out of her? That didn't mean that it was a good thing. After all, she was throwing things at him. He regretted wishing for it, somewhat. "Was I supposed to tell you that I was The Blur? Do you realize how many enemies I have out there that would love to get their hands on the one person who knows who I am? Be reasonable, Lois. I was protecting you."
