Is this really just curiosity? She doubts that. He's trying to dig for information from her, but what for? If what they've been told is true, the entire world is gone so what is there to gain from it?

"It depends on what part of it you lived in. I was lucky enough to be born to a minor noble house." Lies. But if it's a good enough cover to infiltrate that tier of society, it's good enough here. "But most of the people were skaa, basically people treated like cattle."

The same way he's looking to learn about her, she's doing the same. She's certain she's giving off a degree of disdain for the system, which is fine. How he reacts will tell her something about him as well.

"Everything was under the control of the Lord Ruler and his government, and the nobility were no exception. People were kept in line with poverty and threats of mass executions if they stepped out of line."
