What does Joe want?

After many attempts to communicate with nurses, one nurse recognizes his morse code and a man comes who understands it. He asks Joe what he wants. What Joe really wants is to be put back together into a functioning human being so that he can live normally in the world, but he knows that is not possible. He decides that he wants to be used as a freak show and travel outside the hospital to show the horrors of war to people. The man leaves after Joe's request but then returns tell him that what he wants is against regulations. He realizes that they are keeping him a secret and that they want to forget about him. The army doesn't want to show people the horrors of the war because it would discourage them from enlisting. He feels hopeless because he realizes that he will be confined in the hospital and that his loneliness from a lack of contact with people and the outside world will never cease.
