In John Scalzi's book "Redshirts," a character named Hanoen poses an intriguing question about the nature of a mysterious shark. He wonders whether it is a creature composed entirely of ice or one that inhabits icy environments. This thought reflects a deeper curiosity about the boundaries between reality and fiction, a recurring theme in the narrative. Hanoen's inquiry captures the blend of humor and adventure present throughout the story.

The question serves as a metaphor for the characters' exploration of their circumstances and the unexpected elements they encounter in their universe. It highlights their struggle to understand their roles and the absurdities of the world around them, encapsulating the essence of Scalzi's satirical take on science fiction tropes and storytelling conventions.
