Billy is next portrayed as a sad man, who is given doctor’s orders to take a nap daily in order to remedy a weeping problem, however, the first time the reader is introduced to Billy’s naps, he cries instead. When Billy returns to reality, he is loaded onto a train car and time travels again to the night he is taken by the Tralfamadorians. Vonnegut uses the two colors blue and ivory to describe Billy’s feet and hands. These two colors together could symbolize death, as they are often seen in the color scheme of dead bodies. it is here the author introduces a unique metaphor, comparing human freight to liquid that would flow towards light and cooing. The Americans, once off of the freight car, are given overcoats which were taken off of the dead. Billy, like in the past, got the least valuable overcoat, as it was not an officer’s with brass buttons and tinsel but a civilian’s with a frozen fur collar. During the prisoner’s examination, the reader is re-introduced to characters that first were introduced in the first chapter. Edgar Derby and Paul Lazzaro are two characters who both the original narrator and Billy singled out in their stories. Billy, however, gives more detail, and describes the two as having the best and worst bodies of the group. Both were on Roland Weary’s boxcar. Billy again time travels back to Tralfamadore and his time there. Here, Billy is told that ‘free will’ is an idea only heard about on Earth. The Tralfamadores believe that because every second occurs simultaneously, everything that happens to everyone, even choices that they make with supposed free will, is inevitable so, therefore, there is no such thing as free will. As the Americans enter the POW camp, it is the opposite of what they and the reader would expect. Englishmen are there to sing and joyfully welcome them, and there is plenty of food to go around. Another recurring idea from the first chapter makes an appearance: soap and candles are made from the fat of dead Jews. Billy soon finds himself in the hospital after watching a Cinderella play and shrieking too much. He is watched over by Edgar Derby. During another one of his time travels, Billy is found to be in a mental ward in a veteran’s hospital in New York. Here the reader finds that he did not want to marry his wife, who is fat and is eating a Three Musketeers candy bar. Three musketeers is emerging as a common symbol in the story, with Weary and the two scouts calling themselves the Three Musketeers and a different woman reporter in the first chapter eating a Three Musketeers as the beginning narrator tells her his story. In the hospital, Billy is situated next to Eliot Rosewater, who constantly reads science fiction books by Kilgore Trout. These books show similarities with the Tralfamadorians, as they speak of a fourth dimension and a visitor from outer space shaped similarly to a Tralfamadorian.
