The new roles that Sifu has taken on—Old Asian Cook and Old Asian Guy Smoking—reinforce the idea that a person’s identity (and in the novel, this pertains to Asian people specifically) is determined by what they do or how the world sees them, not by who they are on the inside. Willis’s description of his separated parents as having “lost the plot” continues the theme of real life as performance. In the world of the novel, characters are stereotypes before they are people, and they follow scripts rather than speaking or behaving authentically.
