Answer:
Alcohol could be altering Nick's perception of events in chapters two and three.
Explanation:
Nick is the narrator in F. Scott Fitzgerald's novel "The Great Gatsby". He is Gatsby's neighbor and Daisy's cousin. Daisy, it just so happens, was Gatsby's girlfriend in the past.
In chapters two and three of the novel, Nick introduces us to people and events that are crucial for the development of the plot as well as of the characters. In chapter two, he is taken by Tom, Daisy's husband, to New York City. On the way there, they meet with Tom's lover, Myrtle. The three of them and a few others spend the rest of the day in an apartment, constantly drinking. It is an intoxicated Nick who witnesses many of the interactions described to readers along the chapter, including the moment when Tom breaks Myrtle's nose for saying his wife's name without his permission.
The same happens in chapter three. Nick finally attends one of Gatsby's luxurious parties. However, since he knows no one, he decides to get "roaring drunk". Again, it is an intoxicated Nick who finally runs into Jordan Baker, Daisy's friend, and who at last gets to meet the mysterious Gatsby.
Therefore, since Nick is drinking during the events of both chapters, it could very well be that his perception of those events is altered by the alcohol he has consumed. That might affect his memory, his understanding, and his account of things. He is obviously a biased narrator but, by drinking, he becomes even more unreliable.
