Travis is now drifting in and out of the New York City night life, a dark shadow among darker shadows. Not noticed , no reason to be noticed, Travis is one with his surroundings. He wears rider jeans, cowboy boots, a plaid western shirt and a worn beige Army jacket with a patch reading, "King Kong Company 1968-70". He has the smell of sex about him: Sick sex, repressed sex, lonely sex, but sex nonetheless. He is a raw male force, driving forward; toward what, one cannot tell. Then one looks closer and sees the evitable. The clock spring cannot be wound continually tighter. As the earth moves toward the sun, Travis Bickle moves toward violence.
Travis gets a job.
