So what happens to our narrator? At the end, Nick has come to realize that he’s changed and will never be the same. It seems his character dilemma is never fully resolved. We do not know where he will go ("West" is pretty vague), or what he will do, only that he is leaving the house he's resided in for the course of the book. His observation that all the players in this story were “Westerners” is an apt one – it sums up one of the novel’s main themes, the idea that we might be defined by where we’re from, or the kinds of worlds we grow up in.
