A good friend from high school once came out to me in the back seat of a moving car. For a long time, I questioned the choice of location for coming out, and how badly it could have gone had I been of a different disposition, but recently I've come to realize that he must have known he'd be accepted by me and trusted me not to bro out. Then we had Chinese buffet and he told me about all the gay things, so it was a good day.
I am fascinated with Jez. His world outlook and experiences just feel so different from everything and most everyone else in the story so far. He certainly is wasting no potential from the current situation. The transition from College life to life on the road, our knowledge as the reader of Peter's experiences compared to Jez's implied experiences. Two personalities shaped by two very different lives.
It's the end and the beginning all wrapped into one, and this small world has never felt bigger.
