It was strange, listening to Roger's explanation, hearing how things could have been but weren't. On his Earth, anyway. "I recall there being recorded shortages of fossil fuels in the 20th century. And mutually ensured weapon via nuclear weapons was certainly a concern. But it's hard to imagine things getting to the point where someone would actually have instigated that kind of disaster. Especially knowing the stakes involved."

Not impossible to imagine, of course. Especially considering what had happened in the 31st century.
