He agrees that it's horrible how hundreds of people came to Gatsby's parties but none came to his funeral.
Nick is reminded of waiting in train stations on holiday vacations during his youth.
He goes on about the train stations in the Midwest, and concludes that he and the whole crowd – Daisy, Tom, Jordan, Gatsby – were all westerners who just couldn't cut it in the East.
He has a vision of something out of an El Greco painting – a drunken woman in white being carried on a stretcher, a woman whose name no one knows or cares about. Those carrying her then bring her into the wrong house.
After this little vision, Nick decides to go back home. He's had enough of this East business.
But before he goes, he meets up with Jordan, who accuses him of being "dishonest" after all. She says she trusted him, but it turned out he was as "careless" a driver as she is.
Nick's cryptic response? "I'm thirty. I'm five years too old to lie to myself and call it honor." He then remarks that he's "half in love with her" and "tremendously sorry" when he leaves.
Some time later (it seems he's taking it slow with the moving back home bit), Nick runs into Tom Buchanan.
Tom reveals that he's the one who told Mr. Wilson that the car belonged to Gatsby.
Nick can't bring himself to utter the truth – that Daisy was the one driving. He doesn't even know anymore whom to believe.
In the end, Nick realizes that Tom and Daisy were "careless people," people who made messes and then left others to clean them up.
Outside of Gatsby's large, empty house, Nick wanders the "blue lawn" and gazes at the "green light" across the bay – the light on Daisy's house.
He thinks of what the island must have looked like years ago to the first sailors that came to "the new world."
Gatsby was trying to run towards his dream, without realizing it was in the past behind him.
We end with one of the most famous passages in American literature: "Gatsby believed in the green light, the orgastic future that year by year recedes before us. It eluded us then, but that's no matter – to-morrow we will run faster, stretch out our arms farther…And one fine morning--So we beat on, boats against the current, borne back ceaselessly into the past" (9.151).
