"I didn't realize it led to so many deaths. I'm sorry."

"Of blues in particular. The other castes suffered but were not executed in particularly great quantity."

"Still. The coup that led to the Republic of Gilead resulted in... seventeen deaths, outside of Cascadia? Something like that."

"A plurality of Voan blues at the time lived in the capital."

Fred is not sure what to say so he goes for "I'm sorry" again.

"Thank you."

A moment of uncomfortable silence.

"So," Fred said, "why don't your people get some washing machine specs and I will-- actually... hey, Milliways Bar, can you give me a detailed written explanation of any technology that Amenta has and Earth doesn't, in English?"

I can provide copies of published material but I can't do translations proper nor compare unpublished materials.

"But if I copy out the thing I see by hand, then I will get an English copy when I leave?"

Yes. And she produces some examples; on top is an architectural spec for a two hundred story apartment building.

Fred gathers up all the humans and tells them to get to work copying. 

A few minutes into this, he asks the Milliways Bar for an audiobook. The audiobook seemed to be a perfectly ordinary drama, except for an offhand mention of a precog as if precogs were a normal thing that the reader should obviously be expected to know about, and the fact that literally everyone in the setting appears to be a dominant or a submissive. Once he figures out that 'submissive' is not being used in the complementarian sense, Fred considers returning the audiobook and asking for one less pornographic, but honestly he is pretty invested in the romance. 

Avalor sends for some more people to man the bar, including another blue and some more yellows and greens, and then she leaves, because she's got an election in the works. Someone holds the door to Amenta so time can pass towards the official result.

Once the copying is done, most of the humans leave! Fred asks the Milliways bar, "Do I age in here?"

Yes.

So much for the "live forever catching up on other worlds' media" plan.

Fred arranges for Nick to wait in Milliways, then steps outside to wait the zero subjective seconds until Avalor's election. 

Avalor is presently elected and comes back with two more blues - "Commander, these are the ambassadors from Tapa and Cene, who were the easiest to get on short notice and will give an idea of international reception of various possibilities."

"Hello! I'm the alien!"

"It's a pleasure to meet you," says the Tapai ambassador.

"This is very exciting!" says the Cenemi one.

"I'm not sure how much Governor Avalor has told you."

"She didn't explain much until we got here," says the Tapai ambassador. "I wouldn't have believed her, so that's fair."

"She told me it was like my favorite television show," says the Cenemi one, "which makes a lot more sense now that I've seen this!"

"Well, I have several pieces of good news for you. First, we have so much empty space. Second, we're having an infertility crisis and would welcome immigrants who want to have children. Third is the Good News of the Gospel of Jesus Christ but I think my theologians are already working with your theologians on that one and I don't trust myself to explain it."

"Speaking of which, my theologian says that she found your science fiction author very good at explaining for an alien cultural context and would like to talk to her again."

"Won't be a problem, unless her husband objects."

"...why would her husband object?"

"Instead of castes, humans specialize with genders. Men specialize in leadership."
