The Great Gatsby: Chapter 1 - How does the narrator describe Gatsby?

Nick sees Gatsby for the first time at the end of Chapter 1. He describes seeing someone emerge from the shadows of Gatsby's house and stand watching the stars, his hands in his pockets. Gatsby's movements are "leisurely." As Nick continues to watch, Gatsby raises his arms and reaches toward the ocean in what Nick calls "a curious way." Nick thinks that Gatsby was trembling. He seems to be reaching for the one thing Nick can see across the water, the green light at the end of a dock. Gatsby suddenly vanishes. We learn later that the green light Gatsby reaches toward is the light at the end of Daisy's dock. It becomes a major symbol in the remainder of the novel.
