Two Questions:
1. Why does Glass leave Powaqa (the Indian girl) or why does she leave him after he saves her from Toussaint? Wouldn't it have been better for both of them to travel together since they were both lost in the wilderness - and if Powaqa wasn't lost, wouldn't she have helped her rescuer find a way back to food, shelter and medical aid?
2. Why does the old Indian (Powaqa's father) kill Fitzgerald at the end? Does he know Fitzgerald? Was he able to identify him as the man fighting Glass - his daughter's rescuer - from hundreds of yards away when Glass was dressed in the dead Captain's coat?
And why did he kill Fitzgerald, but not Glass?
Did the old Indian's daughter identify Glass to him as her rescuer? If so, no indication was given as she acted like she didn't recognize Glass when she rode by.
