"No, we're born into it. My parents were blue."

"You don't let people do politics unless they're born to the right people? That's--" Wait. Probably he shouldn't anger the godless aliens. "--an interesting way of doing things."

"We'd actually suspected most intelligent species would have invented castes. It allows specialized education and, over time, eugenic selection within each caste for traits that benefit its lines of work."

"Eugenics is against God's will. The last time someone tried it they killed six million people."

"...eugenics is against... God's... will?" she says slowly, like she's not sure she's heard him correctly.

"All people are created by God individually and He loves them all equally, regardless of their abilities. All life is precious, no matter how short or how impaired. We are supposed to care for those afflicted, not to sterilize them or kill them."

"...if you don't sterilize people who can't or won't control themselves, they'll have children, and there will be less room for the children of healthy law abiding citizens who'll be most likely to have healthy law-abiding children. Voa's population control system doesn't take this nearly as far as most countries, we have a two-per-family guarantee for anyone who doesn't commit crimes or resort to social services, but I don't think I've ever heard the claim that the underlying principle was unsound, just that the cost of enforcement might be too high or something."

"Insufficient room is the opposite of the problem we have."

"Really," she says with sudden interest.

"We dumped huge amounts of bitoxphosphene into our atmosphere a century ago. No one knew any better. I-- I don't know how it would affect aliens, but if human women breathe it growing up, it makes many of them infertile, it makes them likely to become infertile as they age, they have miscarriages, children are born and die within a week in horrible pain..." 

"I don't know the substance by name. We do look very similar but I don't know how likely that will be to reflect similar underlying biology."

"It's also possible the bar is modifying what we see to make us look more familiar to each other."

"I have two legs, two arms ending in hands with five fingers each including one thumb per, one head with two eyes, blue hair..."

"That sounds exactly like humans, but we know this place is modifying our speech so that we can understand each other, I don't know whether it modifies 'eight tentacles and a beak' into 'two arms and one head.' You have to admit that sounds more plausible than your species and humans happening to be identical except for hair color."

"Is that also something this place does?" Avalor asks the bar.

Apart from occasional mild size warping, no.

"Not to criticize our distinguished host, but the bar could be lying. --That said, this place's powers probably do not extend outside the place itself, so if we decide to do anything other than have a nice cup of coffee and discuss the existence of God, we should go back to one person's or another's home planet, and then we'll be able to see if either of us has tentacles."

If I may, the bar napkins, if you exit and close the door, the bar will no longer be behind it when you reopen it.

Fred does not believe in letting Aslan decide when you return to Narnia. 

"Is there some way one of us could-- hold the door open, I guess?"

As long as a person from a given world is inside of the bar with the door closed, time in that world will typically be paused. While the door is open to a world, time runs at the same rate in that world and in view of the open door.

"Sounds like a job for interns."

"Yes, that doesn't sound like it will be a problem," agrees Avalor.

"You seemed interested in our infertility problems?"

"We have the complementary issue. The reason Voa was conquered was because someone considered our two-children-per-family policy an inadequate commitment to population control. Everyone wants more children than there is space for them to have, and we don't have an environmental disaster making infertility particularly common."

"Someone conquered you about-- is that that eugenics thing again? They were angry because you were letting the underclass breed?"

"...no, they felt threatened because they believed our population would grow and we'd feel the need to seek more territory from our neighbors by force. Two-per can be humanely net negative if it's enforced strictly enough that people in fact don't have third children, because some people will choose not to have any, and some people spring sideways, and some people die before they can reproduce, and some people can't find partners; but the Empire's ostensible belief was that it would be too easy for people to have third children unauthorized if they didn't have to interact with a population control board in order to have them at all. Someone might go to a hospital in a different city to have their third, say, and if the left hand weren't talking to the right this might go unnoticed until the statute of limitations ran out and we could no longer confiscate and adopt out their baby."
