What is revealed about McCandless's character in "Detrital Wash?" In chapter 4

Chapter 4 introduces us to McCandless’s intense distaste for society abundantly clear. In these chapters, he comes close to rejoining society a few times, going to Los Angeles with the intention of getting a new ID and possibly a job, working in Las Vegas, staying in Bullhead City longer than he has stayed anywhere else, and even working for a McDonald’s using his real name and social security number. Yet each time, he finds himself quickly moving on again, unable or unwilling to reintegrate himself.
