e to the mental ward where he recovered in 1948. In the mental ward, Billy's bed is next to the bed of Elliot Rosewater. Like Billy, he has little love for life, in part because of things he saw and did in the war. He is the man who introduces Billy to the science fiction of Kilgore Trout. Billy is enduring one of his mother's dreaded visits. She is a simple, religious woman. She makes Billy feel worse just by being there. Billy leaps back in time to the POW camp. A British colonel talks to Derby; after the newly arrived Americans shaved, the British were shocked by how young they all were. Derby tells of how he was captured: the Americans were pushed back into a forest, and the Germans rained shells on them until they surrendered. Billy leaps back to the hospital. He is being visited by his ugly, overweight fiance Valencia. He knew he was going crazy when he proposed to her. He does not want to marry her. She is visiting now, eating a Three Musketeers bar and wearing a diamond engagement ring that Billy found while in Germany. Elliot tells her about The Gospel from Outer Space, a Kilgore Trout book. Valencia tries to talk to Billy about plans for their wedding and marriage, but he is not too involved. He leaps forward in time to the zoo on Trafalmadore, where he was on display when he was forty-four years old. The habitat is furnished with Sears and Roebuck furniture. He is naked. He answers questions posed by the Trafalmadorian tourists. He learns that there are five sexes among the Trafalmadorians, but the sex difference is only visible in the fourth dimension. On earth there are actually seven sexes, all necessary to the production of children; earthlings just do not notice the sex difference between themselves because many of the sex acts occur in the fourth dimension. These ideas baffle Billy, and they in turn are baffled by his linear concept of time. Billy expects the Trafalmadorians to be concerned about or horrified by the war...
