The green light represents Gatsby's dream of obtaining Daisy. Nick sees Gatsby reaching for the green light as Fitzgerald says, "But I didn't call for him, for he gave a sudden intimation that he was content to be alone-- he stretched out his arm toward the dark water in a curious way, and, far as I was from him, I could have sworn he was trembling" (Fitzgerald 21).
Chapter 5: Weather
The eyes of Dr. T. J. Eckleburg represent a 'god' in a way or the fact that someone is always watching in the Valley of Ashes. Fitzgerald says NIck feels as if he's being watched when he says, "I followed him over a low whitewashed railroad fence, and we walked back a hundred yards along the road under Doctor Eckleburg's persistent stare" (Fitzgerald 24).
Chapter 7: Tom and Daisy's Daughter
Gatsby's mansion represents Gatsby's physical love for Daisy since he got rich and bought the house across from Daisy and threw parties to get her attention. Fitzgerald says how Gatsby's didn't care about talking to most of his guests at his party when he said, "Sometimes they came and went without having met Gatsby at all, came for the party with a simplicity of heart that was its own ticket of admission"(Fitzgerald 41).
Chapter 9: Mr. Gatz
Throughout the story, the weather represents Gatsby's mood. When Gatsby was reunited with Daisy, it was pouring because he was nervous as Fitzgerald said, "While the rain continued it had seemed like the murmur of their voices, rising and swelling a little now and then with gusts of emotion"(Fitzgerald 88).
Pammy Buchanan symbolizes Daisy's new life and all the time that has gone by since Gatsby first met Daisy. It sinks him back to reality for a little as Fitzgerald writes about how Daisy is trying to help the situation, "'She doesn't look like her father,' explained Daisy"(Fitzgerald 117).
Gatsby's father represents someone who was truly there for Gatsby besides Nick. Although Gatsby was well known and had a huge life, Mr. Gatz represents how family will always be there for you when Fitzgerald said, "About five o' clock our procession of three cars reached the cemetery and stopped in a thick drizzle beside the gate- first a motor hearse, horribly black and wet, then Mr. Gatz and the minister and I in the limousine...."(Fitzgerald 174).
