Final answer:
Nick's motivation to 'get somebody' for Gatsby reflects his willingness to support Gatsby and highlights the themes of companionship and individual quests in Fitzgerald's work.
Step-by-step explanation:
The question centers on why it is important for Nick to 'get somebody' for Gatsby in F. Scott Fitzgerald's novel. Nick's determination to assist Gatsby by finding someone stems from his deep-seated inclination toward aiding Gatsby in his endeavors, which has implications beyond mere social fulfillment.
In Fitzgerald's texts, characters often seek connections with others to achieve personal goals or to provide support in times of need. This trait reflects the humanistic themes prevalent in Fitzgerald's work, demonstrating the characters' desires for companionship and assistance in their individual journeys, as well as their ultimate quest for a sense of belonging in a changing society.
The individualistic and universal appeal of Gatsby's story, expressed through Nick's flawed perspective, amplifies the importance of Nick's role in providing aid to Gatsby.
