After Gatsby's death, Nick learns that it was Tom who told Wilson who was driving the yellow car which killed Myrtle and didn't stop. Or rather who he thought was the driver, the actual culprit was Daisy but Tom was under the impression that it was Gatsby and so was indirectly responsible for the latter's death. Nick is disgusted by both the Tom (who clearly knew Wilson's intentions as he was holding a gun and still felt completely 'justified') and Daisy (who never told Tom the truth, allowed the blame to fall on Gatsby and did not even attend his funeral). Nick describes them as people who 'smashed up things' before retreating into their 'vast carelessness'.
Nick cannot forgive or like Tom because of his dishonesty and treatment of others. He criticizes people like Tom and Daisy for their privilege and careless disregard for the consequences of their actions on others. Nick sees them as selfish and morally corrupt individuals.
Nick advises Gatsby not to try to repeat the past with Daisy, as he cannot recreate what they had before. He also warns Gatsby about the dangers of pursuing an idealized version of Daisy that may not exist. Ultimately, Nick encourages Gatsby to let go of his obsession with Daisy and move on.
The scene with Pammy shows Gatsby the reality of Daisy's life with Tom Buchanan and their daughter. It makes Gatsby realize that Daisy has her own family and responsibilities that he cannot simply erase. It serves as a reality check for Gatsby and deepens his understanding of the complexity of Daisy's situation.
The people on horseback who visit Gatsby's house in "The Great Gatsby" are a trio of well-to-do guests from East Egg. They are Jordan Baker, Tom Buchanan, and Daisy Buchanan.
Gatsby escapes from reality. He is stuck in the past. He cannot get over Daisy and he is not willing to let go of his dream of having her.
Gatsby knows Jordan Baker through their mutual connection to Daisy Buchanan. Jordan is a friend of Daisy's and is introduced to Gatsby through their social circle. Gatsby is initially intrigued by Jordan because of her association with Daisy.
Daisy
Myrtle was accidentally killed by Gatsby's car, when Daisy was behind the wheel but Gatsby was driving. Daisy was under the influence of her emotions and did not stop after hitting Myrtle.
Gatsby met and kissed Daisy in the summer. The encounter took place at Daisy's house in Louisville in 1917.
Jordan Baker plays the piano when Gatsby, Nick, and Daisy are in Tom and Daisy's house.
Daisy is appalled at Gatsby's party because of its extravagance and lack of sophistication. She is used to a more refined social circle and is taken aback by the excess and frivolity of the party. Daisy also may feel uncomfortable in the unfamiliar setting and with the attention that comes with Gatsby's wealth.
In "The Great Gatsby," Daisy never reads the letter from Gatsby. Tom discovers the letter and shows it to Daisy, who decides not to confront Gatsby about it. Daisy chooses to remain with Tom, ultimately betraying Gatsby.
Gatsby and Daisy meet again at Nick's house for tea when Gatsby arranges the meeting. This occurs in Chapter 5 of "The Great Gatsby."
