Sometimes Steve felt bad while sparring, because many of his skills had been chemically induced. He had become strong because of what the military had done to him. Sure, everything else had been his own doing (the honing in of his skills, the quick decisions on how to use them) but unlike Henri his strength had been given to him.
Part of him wanted to go easy on her, but another part realized she probably wouldn't appreciate it so he ducked the left hook that was never meant to hit him anyway. He saw the hand that had been moving for his chest and grabbed Henri's wrist quickly, pulling her down to the ground hard.
