Outside, the world is recovering from the effects of the war and Ophelia is able to experience things she has previously only known about via her father's lessons. They discover the cattle owners are Johnson's community, and Bill is soon reunited with Catherine, who is heavily pregnant with her eighth child. She married Johnson when she was in her teens, but six of the children she has already given birth to have died in infancy due to genetic mutation. Since Johnson is old enough to be Catherine's father, Ophelia is disgusted, thinking the outsiders are uncivilised compared to the people in the bunker. Dwight retorts that the latter are like "dinosaurs", attempting to maintain pre-war standards of living and not adapting to the changed conditions in the world.
