Loyalty is another theme in the book. Although it may seem strange, John's extreme loyalty to Mkatie's family is the reason why he restrains her in the end. John is a member of the Zulu people in South Africa. As the narrator notes in the beginning, her mother had always "preferred Zulu servants," because they "were obedient, conscientious, and fiercely loyal. Their society was built on loyalty." As noted above, John demonstrates his loyalty to the narrator and her sister, Mkatie, countless times.
