“Then I heard footsteps on a stairs and in a moment the thickish figure of a woman blocked out the light from the office door.”
After they arrive at Wilson's car garage in the Valley of Ashes, Nick sees a woman, Myrtle, who is coming down the stairs to meet up with Tom.
"No, you don't, Myrtle'll be hurt if you don't come up to the apartment. Won't you, Myrtle?"
After Tom gets a dog for Myrtle, Nick wants to leave, saying that he has to leave them there. However, Tom immediately interjects and uses Myrtle as an excuse to forcefully keep him there.
"It's just a crazy old thing. I just slip it on sometimes when I don't care what I look like."
After arriving at the apartment and inviting guests, Myrtle changes out of an outfit a second time into a more expensive wear. Due to this, she now acts as if she is better than anyone else.
Myrtle and her sister started bad mouthing Daisy, catching Tom's attention and telling her to not repeat her name. Myrtle took it as a challenge, repeating her name multiple times. This then led to Tom breaking her nose.
"Daisy! Daisy! Daisy!" shouted Mrs. Wilson. "I'll say it whenever I want to! Daisy! Dai----"“Making a short deft movement Tom Buchanan broke her nose with his open hand.”
