She was going back to the cabin, and he saw her moving in the brush, and shot.
Can you imagine how horrible that would be??
A guy I went to school with accidentally shot and killed his father on a hunting trip while we were in high school. They were getting ready to pack up and go home and as my classmate leaned his rifle against the back of the truck, it went off and killed the father. We were all so horrified. No one knew what to say or do around him. I don't know what it would be like. I ran into him years later and he seemed to have come to terms with it, as much as anyone can. However, it is one of those things where the mark never goes away.
