SetupStatus Quo

Theme
Gilliam tells Curtis that everyone has their preordained place: "You know what I hate about myself? I know what people taste like. I know babies taste best." This foreshadows the theme that survival within this system requires unconscionable compromise.
Worldbuilding
The tail section's hierarchy is established: protein blocks as food, children being measured and taken, Mason's cruelty demonstrated when she freezes a man's arm for throwing a shoe. Curtis, Edgar, and Gilliam plan their rebellion while receiving cryptic messages hidden in protein blocks.
Disruption
The guards take two children, including Tanya's son Timmy and Andrew's son Andy, measuring them before dragging them toward the front. This child abduction galvanizes the tail section and transforms Curtis's simmering resentment into urgent revolutionary action.

Crisis

Act III
ResolutionSecond Threshold
Curtis enters the engine room and meets Wilford, who reveals the horrifying truth: the revolution was orchestrated, Gilliam was complicit, and Curtis was chosen to replace Wilford. The system manufactures its own opposition to maintain population control and balance.
Synthesis
Curtis confesses his darkest secret—he ate babies to survive and nearly ate Edgar. Wilford offers him control of the engine. Curtis discovers the missing children are enslaved inside the engine as replacement parts. He rejects Wilford's offer and helps Namgoong detonate the explosive.
Transformation
The explosion derails the train. Yona and Timmy emerge as the sole survivors into the frozen world. They see a polar bear—proof that life exists outside. Curtis sacrificed himself not to control the system but to destroy it, enabling genuine freedom rather than cyclical oppression.
