During the scene at the Morningside Heights apartment, how does Nick initially react to the behavior of the other characters? How does he end up behaving differently from the way he acted back home, and why is this significant?

Tom takes Nick and Myrtle to New York City, to the Morningside Heights apartment he keeps for his affair. Here they have an impromptu party with Myrtle’s sister, Catherine, and a couple named McKee. Catherine has bright red hair, wears a great deal of makeup, and tells Nick that she has heard that Jay Gatsby is the nephew or cousin of Kaiser Wilhelm, the ruler of Germany during World War I. The McKees, who live downstairs, are a horrid couple: Mr. McKee is pale and feminine, and Mrs. McKee is shrill. The group proceeds to drink excessively. Nick claims that he got drunk for only the second time in his life at this party.

The ostentatious behavior and conversation of the others at the party repulse Nick, and he tries to leave. At the same time, he finds himself fascinated by the lurid spectacle of the group. Myrtle grows louder and more obnoxious the more she drinks, and shortly after Tom gives her a new puppy as a gift, she begins to talk about Daisy. Tom sternly warns her never to mention his wife. Myrtle angrily says that she will talk about whatever she chooses and begins chanting Daisy’s name. Tom responds by breaking her nose, bringing the party to an abrupt halt. Nick leaves, drunkenly, with Mr. McKee, and ends up taking the 4 a.m. train back to Long Island.
