"If your gut makes new gut cells are they born polluted like you?"

"Yes."

"Sooo. If we injected a bunch of your gut cells into lo-cal animals would they and all their child-ren will be polluted from then on?"

"...probably, I guess."

"Want me to do that some before we leave?"

"I don't know if it'd actually work... none of us are theologians."

"I tried to figure out that stuff but it didn't make any sense."

"I haven't even tried so I don't know that I can help you."

"Should I do it just in case?"

"I... don't know if you should?"

"Why not?"

"...because I don't know how the cleans will react and that is the important thing."

"Oh."

"They should stop being so important and let you have a turn."

The red blinks at her.

Vira blinks back.

Eventually they decide that this statement doesn't require a response and go back to what they were doing (being flop).

Eventually the reds return to Amenta, where the amaliens deconomatinate and then head onward, back to the amalien planet.

The reds discuss the matter among themselves.

They don't really think they're competent to settle a new planet, or that the resources necessary to let them mostly survive the learning curve will actually be forthcoming without major administrative hiccups of the "no one actually cares about this result, just about looking like they tried" variety. But they are mostly agreed that it sounds - better than soft genocide.

Lots of them may die, but. If they have any grandchildren at all they will have fertile free grandchildren who can be anything they want on a beautiful planet all their own surrounded by trees.

They put together volunteers who want to break ground, plant seeds, chop down trees and try turning them into cabins, and so on. They put together a list of tools and supplies they think this group will need, plus guesstimates of further shipments they'll want in the future depending on how the crops do, and ask the amaliens to present it to the Voan government.

Meanwhile, Deet has been getting amaliens organized so they can indust-rialize and things as Lucien and him had planned earlier. A bunch of them know how to build houses and tools and chop down things pretty fast now. They also have metalworking on a much larger scale then they previously managed. 

Lucien is happy to present the red's list to the Amentan government, though he tacks on an additional request for a colony ship from the amalien homeworld for bringing any amaliens who want to go there. 

...the amaliens who go there know they need to maintain a reasonable (Amentan) standard of cleanliness if they ever want to... leave... again... after living with reds for however long... right? Like it shouldn't be a big deal if they're just going ahead of the waves of settlement to put down infrastructure but if they're interacting more directly they need to be paying attention to that.

.... 

Sigh.

Are there some basics they should know about? He can pass them onto amaliens who will make their own individual decisions about it.

Here is how to do a full decontamination shower! Here are the barriers sufficient that you don't need to! Since they are indestructible they could in principle do one of these things that Amentans sometimes do to inanimate objects if that were ever more practical but it sounds really unpleasant!

Could they do those things even after they've been around reds not doing the other things for a while?

Maybe but it's a theological gray area because amaliens are living people and it's not entirely clear how pollution becomes incorporated into the nature of a living person.
