Chapter 6 - Foreshadowing

Billy obviously knows when and how he is going to die because he is a time traveler, but there is foreshadowing of his murderer. When talking with a co-POW named Paul Lazzaro, Billy knows that Lazzaro will be involved  in Billy's murder. This is foreshadowed when Lazzaro states, "...Whenever the doorbell rings, have somebody else answer the door" (141). This shady and sinister quote pretty much solidifies that he will murder Billy Pilgrim.
