In the fight between Karen and Nicodemus, he has just shot Karen in the belly during their sword fight. She still manages to get Fidelacchius to his throat somehow...and then when she strikes while he is defenceless (after asking to be saved and removing his tie, coin and weapons) she then breaks the sword. Immediately he headbutts her and strikes her in the jaw. Then she fights back and loses their sparring and ends up in a lock the forces her to her knees. Then SOMEHOW he strikes her knee and breaks is, and she falls to the ground. The thing is though..how is that possible? She was already on the ground kneeling (a very strong position for a knee for a start) and then he breaks her knee and she falls to the ground again. But she was ALREADY on the ground
Karrin seemed to gather herself together. She flicked a quick blow at Nicodemus’s face, forcing him to duck, and then their hands engaged in a complex and swift-moving series of motions that ended with Karrin’s left arm held out straight, while she was forced down to her knees on the freezing sidewalk.
Nicodemus twisted Karrin, tilted his head to one side, and then drove his heel against her knee with crushing strength. I heard bones and tendons parting at the blow. Karrin choked out another sound of pain, and crumpled to the ground, broken.
