In "The Son of Neptune," the character reflects on the concept of fairness, particularly in relation to life and death. The speaker, addressing Frank Zhang, challenges the idea that life should be fair, pointing out that fairness is often an illusion. The speaker emphasizes that life can be fleeting and unpredictable, using Frank's mother's guidance to the Afterlife as an example of how death does not adhere to notions of fairness.

The speaker continues by asserting that despite the absence of fairness in death, they are committed to fulfilling their responsibilities. This suggests a resigned acceptance of the inevitable nature of life and death, indicating that one must do their duty regardless of the circumstances. Ultimately, it highlights the complexities of mortality and the subjective nature of fairness in human experience.
