In Neil Gaiman and Terry Pratchett’s novel Good Omens, an unusual mix-up occurs when an angel and a demon are tasked with the care of the Antichrist. Instead of the intended child, an extra baby is accidentally switched at birth, leading to unforeseen consequences.
This extra baby, whom we later learn about, is named Adam and he grows up in the small English town of Lower Tadfield. He is raised by a loving family but remains largely unaware of his true potential as the Antichrist until the climax of the story. Adam possesses extraordinary powers but also a strong sense of morality, which ultimately plays a critical role in the storyline.
The real twist is that throughout his upbringing, Adam is just a normal boy, having typical childhood experiences and forming friendships. His character develops as he grapples with the implications of his identity. In the end, Adam chooses to embrace his humanity over his ominous destiny, which is a central theme of the narrative.
Thus, the fate of the extra baby is not just about what happens to him physically, but rather how his journey reflects on themes of choice, identity, and the nature of good and evil.
