"... Twenty-five years?"

It is absolutely a guess, but Alfredo next says, "And, if I may, sir - xir?"

Somehow sir doesn't suit a Helpmate as well as a human - maybe it would prefer ma'am outright? - but he charges forth regardless, "Do you know what worlds came together to construct this dome? Why did they bring the palmamis here?"

Maybe tying it back to the original topic would help, somehow.
