The remote beach house setting functions almost as a character, it isolates the protagonists from help, limits their resources, and creates a contained environment where the infection can spread unchecked. The fog and shifting coastal landscape mirror the world out of balance, amplifying the sense that nature itself has turned hostile.

The infection serves as both a literal biological threat and a metaphor for ecological collapse and loss of control. It drives characters to mutate and lose their humanity while forcing impossible moral choices. The fog acts as a barrier to safety, trapping characters in a space where they must watch each other deteriorate.
