Gatsby confides in Jordan, hoping she will convince Nick to help him reunite with Daisy. Jordan relays the story to Nick and asks that he host a meeting with Daisy and Jay at his house. When Nick questions why Jordan did not arrange a meeting, she responds that Jay wants to show Daisy his house; since Nick lives next door to Gatsby, it is logical to meet at his house.
Jordan’s comment “And Daisy ought to have something in her life” alludes to Daisy’s unhappy marriage. Tom has been cheating on Daisy since their honeymoon, and he has shown no interest in fidelity, even though his wife and the rest of society are aware of his behavior. Previously, Myrtle had telephoned Tom during dinner, and Jordan had tried to eavesdrop, which seemed to make light of the situation. However, in this scene it becomes clear that Jordan realizes how serious the situation really is, and she knows that Daisy is unhappy. Her comment is meant to express to Nick that Daisy deserves some happiness in life, and that she believes Jay is the person who can bring Daisy that happiness.
Jordan has been affected by Jay’s story. As a teenager, she had seen Daisy and Jay together and had been struck by their chemistry. She has always remembered the young officer who “looked at Daisy…in a way that every young girl wants to be looked at sometime.” She never realized that the young man was Jay Gatsby. However, now Jay has expressed his interest in rekindling his relationship with Daisy, so Jordan wishes to bring her friend back to a happy relationship.
