Describe the tone of the last three communications from McCandless in chapter 7

In the previous section, McCandless attempts a few times to rejoin society, but finds he cannot stomach it for long. Here we see, however, that he does seem to be planning to settle down after his Alaska trip—his last great adventure. Although it is tragically impossible to know whether he would’ve actually settled down, that he was planning on it at all shows that he did not see his lifestyle as a permanent one, and it also refutes on some level the idea that his Alaska trip was intentionally suicidal.
