"Nuclear holocaust, yeah. People created Cylons back home. They were machines, basically robots? And they essentially had served as slaves to the human race. Before I was born, while my dad was in the fleet as a young man, they rebelled. There was a huge war and eventually an armistice leaving them in their own airspace and us in ours. A few years ago, they waged all-out nuclear war on our planets. They had evolved enough to look like humans, even though they were still machines. They could regenerate themselves on their base ship. There were a bit less than 50,000 people in all of the colonies who survived that. By the time we managed to find a place to stay and make some sort of peace, we had around 38,000 people left in the entire human race. Plus that of the planet we landed on." Lee wouldn't ever classify himself as talkative, but he could carry on a conversation. Even if it were depressing, probably more easily if he were passionately interested.
