Question: When Wayne exits Jason's ranch by guiding his horse backwards (a display of fine horsemanship and/or animal training, by the way), you may notice that he is holding his right hand exactly the same way as he does later in the movie when he has the bullet-against-the-spine problem and is temporarily paralyzed toward the end of the movie. Perhaps he did have a problem with his hand at that time, and the script was altered accordingly?
Question: When JP is taking a bath in the jail, his leg is propped up out of the water. It reveals a significant ankle injury. From what?
