The scene in the movie I am talking about is when she first approaches him and they go back to his hotel. They are fighting and such and she ends up on top of him. He's lying on his back and she has (I believe) a broken chair leg in each hand and she's trying to stab at him with it. He has both her arms at the wrist and his arms are shaking, because presumably she is just so strong. No. Can smaller people defeat larger people in fights using technique? Yes. In that moment though, it was strength v. strength and he was struggling.
Even if he didn't want to hurt her, I cannot imagine he couldn't have just tossed her off of him and been done with it.
It's right at the end of this clip. His arms are shaking. Give me a damn break.
