Kay's fist smacked against the palm of Mac's hand. Her form had improved noticeably. Not perfect, Mac noted, but at least [member="Lady Kay"] was a quick learner on that regard. The improvement in form had also allowed the punch to be delivered more effectively. Mac's palm stung a little. "Better. Much much better." Mac continued to keep his arm outstretched. "Again."
Like anything, practice makes perfect. Mac signaled for Lady Kay to strike his hand repeatedly and when his palm began to bruise a little from the repeated blows, he switched hands and signaled for Lady Kay to do the same, now punching with her left hand. She wasn't calculating as much, though Mac could still tell that she was conscious in about her form. She needed to rely on her instincts. After repeated strikes with both hands, her form began to improve. However Mac noticed that there was something missing from Lady Kay. He knew what it was of course, it was the same ingredient that allowed Mac to be the fighter that he was. Raw emotion.
Whether it be anger or fear or compassion or determination, every fighter had to have some sort of emotion to push them far past their limit. From Mac's experience, every fight eventually boiled down to sheer will power and it was the emotions that built such power. The fear of death creates the will to live. The anger creates the desire for revenge. Compassion breeds a want for peace through victory. It was not evident to Mac that Kay possessed any such emotions. That was understandable of course. Mac slowly realized throughout the exercise that, despite being a force user, Kay was not a fighter. But Mac could change that. Such raw emotions rarely came out in such low stakes situations. No, Mac needed to see what Kay was really worth.
As Kay threw another punch, Mac grabbed her fist with his right hand and pressed his left hand on the back of her elbow, forcing his hand against the joint and giving him manipulation of her arm. He twisted her arm so that he could easily pop it out of its socket, he had done it before. Mac had no intention of doing so, but Kay didn't know that. He figured that he hadn't completely gained Kay's trust and she still harbored some fear of him as he did of her. He executed his counter to Kay's punch with a sudden harshness that suddenly made the situation feel very real. He wanted to see Kay's reaction, to light a fire under her, so to speak.
