 The U.S. Navy destroyer, relatively well-stocked with food but low on nuclear fuel, will scout northern Africa, then make her way to the Pacific Ocean in search of habitable land for the two crews.Thomas keeps the deal he made with the Soviet captain (trading food and a place for the Soviets in any society the "Nathan James" crew builds on land for nuclear fuel, if found at the Soviet base) from most of his crew, in order to not get their hopes up.
