Final answer:
Gatsby's change in demeanor after coming out with Jordan hints at an emotional shift, likely tied to Daisy, and reflects Fitzgerald's themes of unattainable love and the unique individuality of his characters.
Step-by-step explanation:
When Jordan and Gatsby come back out together, there is a distinct change in Gatsby's demeanor that is noticeable. This change likely reflects a moment of vulnerability or a shift in his emotional state, which may suggest his deep feelings towards Daisy and the anxieties or pressures he feels in trying to sustain the persona that he has crafted for himself. In F. Scott Fitzgerald's works, characters such as Gatsby are deeply complex, and their changes in behavior are often significant, encapsulating the novel's larger themes of longing, aspiration, and the ephemerality of the American Dream during the 1920s. While Gatsby may appear great on the surface, he is, in Fitzgerald's narrative, a uniquely individual character whose story cannot be generalized to represent anyone else's experiences—baron, brewer, or bootlegger. This particular change in Gatsby's demeanor is likely connected to the powerful influence of unattainable love, one of the central themes Fitzgerald returned to in his work. It can tell us about Gatsby's persona as being crafted and fragile, sensitive to the nuances of his social interactions, especially those pertaining to Daisy.
