Joe's emotions

Joe is finally getting to the point of communicating with a nurse. He finally gets the nurse to understand his morse code and then a morse code reader comes in to decipher what Joe is trying to say. Joe desperately wants out of the hospital, so he wants to become a traveling freak show. He can't do anything else but show people what has happened to him. Even though his situation is very demeaning and showing his 'freakish' quality is, he wants to be out of the hospital. The army will no allow this because they do not want the outside world to see what can happen from war and they are scared of the fear Joe's condition would cause. Therefore Joe will remain stuck in the hospital.
