He was conscious of the other agents watching and (in some cases) clearing out, but Slade also couldn't have cared less. A brawl hadn't really be his aim when he'd come here, but clearly Dick needed it so he was willing to make certain concessions. Of course, when it came right down to it, in a straight-out contest of strength, Slade would win thanks to his body's enhancements. He could hit harder and faster, and he knew exactly where Dick would hurt the most.
For that reason, though he was also taking blows in the fight, he was fairly certain that he would last longer than Grayson.
