Certain characters prioritize self-interest, whether through hoarding resources, abandoning allies, or colluding with external parties. These figures introduce moral complexity and danger that extend beyond zombie attacks. Their presence forces protagonists to constantly reassess trust and cooperation, driving narrative tension and character development.
Supporting Characters and Evolving Relationships
Beyond primary figures, a wider network of students and staff contributes to world-building and thematic depth.
