In John Scalzi's novel "Redshirts," the concept of being expendable is humorously explored through the lives of characters in a science fiction TV series. Abnett articulates the role of 'red shirts,' highlighting the trope of minor characters who often face peril in such narratives. This commentary points to the absurdity and often comedic nature of their existence within the story.

The book delves into the lives of these characters as they become aware of their fates, ultimately questioning the nature of reality and storytelling in a genre defined by such conventions. Scalzi cleverly blends humor and existential themes, turning what is typically a grim fate for background characters into a reflection on agency and purpose in life.
