Christ

When Joe is sedated, he has a dream about Christ. The dream relates to his earlier memory of the train station when he went off to war. There was a woman calling for her son and saying that he did not belong in the war, he was only sixteen years old. Joe sees the woman’s son, and he realizes that he is Christ.
Joe is in the train station and sits by while a group of men are playing cards. The men all sitting in the train station have something in common: they are all going to die in the war. They play cards and discuss their deaths, and Christ joins them and proves that he is Christ by making whiskey appear for the men.
One man playing cards points out Joe and pretty much said that he doesn’t belong there because he is not going to die. But, Joe tells the men about his fate. He is just the stub of a man with no arms or legs, no face, and no way to communicate with others. That shuts the other men up and they agree that being Joe is worse than being dead.
The men all get on the train, and Christ leaves because he has other dying men to see. Joe feels like he does not belong on the train, so he gets off. By getting off the train he puts himself in a place where he is neither alive nor dead. Joe finds Christ and cries at his feet asking for mercy.
