Despite his fantastic story, Dale believes the Doctor. The peace with the Draconians lasted many years, but suddenly devolved into senseless acts of hostility. The Doctor's story would explain a great deal. Dale outlines the escape plan: Cross, one of the overseers, will leave two spacesuits near an airlock, and they will walk across the lunar surface to steal a spaceship. Dale offers to take the Doctor back to Earth where he can tell his story to Dale's contacts in the press and government. However, once inside the airlock, they find oxygen tanks for the suits are empty. Cross has double-crossed them, and the room is depressurising.
