Here's a breakdown of their relationship:
* Daisy Buchanan: Nick's second cousin once removed. They share a family connection through Nick's mother.
* Tom Buchanan: Daisy's husband, and thus Nick's cousin-in-law.
* Jordan Baker: A friend of Daisy's and a professional golfer. While not directly related to the Buchanans, Jordan becomes a central figure in the novel through her connection to them and to Nick.
It's important to note that Nick's relationship with the Buchanans is not a close one. He describes himself as "a guest" in their world, often feeling like an outsider observing their extravagant lifestyle and complicated personal lives. This distance allows him to serve as a more objective narrator, offering a critical view of their actions and motivations.
