One day, as Nick and Tom are riding the train into the city, Tom forces Nick to follow him out of the train at one of these stops. Tom leads Nick to George Wilson’s garage, which sits on the edge of the valley of ashes. It is at this valley of the ashes that Nick first meets Tom's mistress Myrtle Wilson. The two men proceed to a car repair garage owned by George Wilson, a "spiritless man" who is also Myrtle's husband. Tom taunts Wilson and chats briefly with him about business matters. Later, Tom forces both Myrtle and nick to accompany him to the city. Myrtle lies to her husband claiming that she is off to visit her sister in New York and accompanies them. He carries the to the apartment in which he has his affair, and they have an impromptu , shrill, vulgar party with Myrtle's sister, Catherine and a repulsive couple called McKee's. The group gossips about Jay Gatsby and Catherine claims that is somehow related to Kaiser Wilhelm, the much-despised ruler of Germany during World War 1. The group proceeds to drink excessively. Nick claims that he got drunk for only the second time in his life at this party. The behavior and conversation of the others at the party repulse Nick but though he is repulsed by this vulgarity, he is too fascinated to compel himself to leave. He says that he was "within and without, simultaneously enchanted and repelled by the inexhaustible variety of life."
As the afternoon wore on, Myrtle became increasingly intoxicated and she becomes more outspoken about her situation in life, her marriage, her impassioned first meeting with Tom, and finally Tom's marriage with Daisy. When she begins to talk about Daisy, Tom sternly warns her never to mention his wife. Myrtle becomes enraged and blurts out that she will talk about whatever she feels fit whenever she wants, and begins to chant Daisy's name loudly, mocking Tom. Making a "short deft movement" Tom lashes out with his open hand and breaks Myrtle's nose which causes total confusion. This abruptly ends the party on a low note and the guests make their drunken departure.
In this chapter it becomes clear that Tom is a bully and a hypocrite as he carries on a public affair, but still feels compelled to abuse his mistress in order to keep her in place.
