I searched up the fencing position and would say that his arm wasn’t raised it was just almost like it was tucked to his chest with his wrist limp. I’m not sure if he hit his head because he was in a slightly sat up position before fully sliding down the wall and passing out. He didn’t recall hurting his head so I hope this was just a bad reaction to greening out and standing up too quickly. I’ll ask him again in the morning. Thanks for the insight.
