Buffy watched him stumble back and backed up herself. This guy was strong and confirmed it by stating it to her. “I don’t know who sent me. Some guy. Told me ‘To find Batman’ whatever the hell that was.” She laughed before continuing “which clearly is you... with the suit. If you’re so strong, why do you even wear it?”<br/><br/>This guy was tougher than the other humans Buffy has faced and she was curious as to why. “So you a demon or something? Human who made some deal with a witch to make then superhuman?”<br/><br/>She was just given directions to hurt this guy, not kill him. And by the first few  minutes they’ve interacted, it was going to be hard for her to hurt him significantly.
