The Cart Before the Wings
At the cabin's end (Chapter 6), Leif builds a rocket cart from salvage—rusted metal, a boiler, a pilot seat—with trembling hands. Leif: “"This will work."” Katita: “"It always does. Until it doesn't."” The pressure in his shoulder-blades is unbearable now; he can feel something pushing against skin from the inside. Not pain. Anticipation. Leif: “"When do I ask you?"” Katita: “"When you can't hold it anymore."” Outside, the desert night fills with pursuit: wild dogs, military police, Dirtheart activists in animal masks, a farmer's wood-chipper mech grinding across red earth. The cabin burns. They load into the cart. As it accelerates downhill toward the city's mouth, toward the beach, Leif feels his back split open. White wings, enormous and newborn, unfold from his spine. Katita: “"Oh god oh god no—"” But it's too late. The wings catch air. Leif flies. The cart crashes empty into the beach, and the episode ends mid-flight, suspended.
