At first he is mesmerized by the glitz and glamour of the world that Tom, Daisy, and Gatsby inhabit. He does not go as far as they do in their callous treatment of others or each other, but he still comes along for the ride. As events unfold he begins to see the corruption and becomes disgusted with all of them, except Gatsby, whose story has only started to be understood. Instinctively, Nick knows that Gatsby is not 'old money' as he lets on and in an impulsive moment tells Gatsby that he's more man than a room full of Toms and Daisys. Disenchanted with the shallowness his midwest values and morals return to him and he leaves after Gatsby's funeral to return home.
