Phoenix is an aged woman with a strong determination. Her grandson is ill and unable to fend for himself, so Phoenix takes it upon herself to care for him. The question that bothers me is as to where her grandson's parents are. The only inclination given is that they are not there. But it makes one wonder what happened to them. Another question would be as to what occurred in Phoenix's past for her to memorize that path so perfectly. Her memories merge into her everyday actions, but they don't point out what happened in her past.
On the way to get her grandson's medication, Phoenix encounters a hunter. He points a gun at her after helping her up, two very different actions. The time period and the action with the gun sadly makes sense. But him helping her up and speaking in a polite/semi-polite manner made me wonder if the hunter and Phoenix have history together at some point. Another thing was her situation with the pharmacy. As soon as she stepped in, she became a completely different person. She was timid, quiet, and withdrawn, nearly silent for the first part of her visit. That situation made me wonder what caused that behavior, which goes with the overall question: what happend in Phoenix's past?
