Nick Carraway narrates chapter 4, as he does the whole novel, but he allows Jordan four or five pages to tell the story of Daisy's history with Gatsby and Tom in her own words. As Nick sets the scene, he meets Jordan at the Tea Room in the Plaza Hotel, and she tells him the story while sitting up very straight in her chair.
The story reads more like a letter Jordan might have written, but Nick is at pains to describe it as an oral narrative. It is as if he transcribed it word for word—but he never says he does that, and it would be a very odd thing for him to do, especially over tea in a fancy hotel. Therefore, he almost certainly must be reconstructing the narrative from memory—and then putting it into Jordan's voice as if it is entirely Jordan's story.
In this section, Jordan describes how much she admired the older Daisy. She talks about how popular Daisy was, and how she came across Daisy once with Gatsby, a young officer, sitting with Daisy in her white roadster. The two were utterly absorbed in each other. As Jordan describes it:
The officer looked at Daisy while she was speaking, in a way that every young girl wants to be looked at sometime, and because it seemed romantic to me I have remembered the incident ever since. His name was Jay Gatsby and I didn’t lay eyes on him again for over four years—even after I’d met him on Long Island I didn’t realize it was the same man.
Later, Jordan tells the story of Daisy's marriage to Tom, strongly implying that Daisy didn't want to marry him. She also tells Nick that Tom's infidelities started as soon as he was married and that there were scandals because of Tom's behaviors.
Nick apparently includes this passage as a verbatim first-person tale from Jordan's own mouth to make it as credible as possible. He does this so that we will fully believe in this version of the story. Of course, what the reader must keep in mind is that this is a third hand account. It comes through Jordan to Nick and from Nick to us. We are called to question how much Jordan's story has been altered by Nick, intentionally or not, to coincide with the portrait of Gatsby that Nick is trying to create.
