Who is described as the quintessence of the Jazz Age, reminiscent of a Scott Fitzgerald character?

The description of someone as the "quintessence of the Jazz Age," evoking the essence of a F. Scott Fitzgerald character, clearly points to the character of Boy in "Fifth Business." Throughout the novel, Boy is portrayed as a charismatic, flamboyant individual embodying the extravagant lifestyle and cultural shifts of the Jazz Age, much like the protagonists found in Fitzgerald's works.

Boy's personality, his pursuits in life, and his romantic entanglements reflect the hedonism and complexity of that era. He is depicted as someone who revels in the pleasures of life and is deeply engaged in the social scene, making him a fitting representation of the flamboyant spirit that characterizes the Jazz Age.

In contrast, characters like Dunstan Ramsay and Willie Ramsay have very different narratives and traits that do not align with the Jazz Age's extravagant and carefree spirit. Sam West, while having his own significance, does not capture the same embodiment of the Jazz Age lifestyle as Boy does. Thus, Boy stands out as the quintessential character representative of that period.
