Is there something we should do to make you comfortable?

Um, the other unclean things are people's waste and garbage.

I guess you should pick a human village that has plumbing?

They don't all have plumbing?

No? There are a lot of humans.

There are thirteen billion Amentans and literally all of them have plumbing unless they are camping.

Well, I don't think it's even a majority of humans. 

I guess that is good to know.

If you think it's important you can tell the engineers how your world does it, maybe.

So, uh, do you have any things that you figure are unclean here or is that just not a thing.

I mean, we have things that aren't clean? Like, if they have dirt on them. I don't think we have the concept you're using.

Oh. I guess I can explain about being red then if people still wanna know.

I think the Prince Canafinwë would probably be happy if someone reassured him that it isn't something his brother will yell at him for not getting to the bottom of sooner.

Apparently you won't care! We're the people who have to do all the unclean jobs.

...and you thought we might kill you if we found out?

Well, see, since we've been doing them for so long reds are unclean too. And we touched things.

...I think I still don't understand. 

Everybody thinks we're gross and hates us.

Oh.

That's awful, I'm sorry.

Thanks.

What insanity.

It's not great. Although it's not actually why Katin was in danger, that was just because I didn't have her credit paid off, my country'll kill uncredited babies of any caste.

- they'll kill babies?

If you don't have a credit for them, yeah. Most places just take them and adopt them out and sterilize you maybe with a jail term for that.

She bursts into tears. Oh no - oh no -
