Continuity

 * This story is set during the end of the world. The "healthy" people have already left to extend the human race, leaving the few unlucky unhealthy ones to be on Earth as it is destroyed. This doesn't seem to fit well with TV: The End of the World, but instead fits more with TV: The Ark, with references to "arks" leaving the planet.
