Q. If humans successfully bring back extinct species such as the Auroch, would the Being that was formerly the Auroch and is now cattle, go back to being an auroch?

A. Sadly, no. Selective breeding is great for trying to re-fill the archaeological niches we’ve emptied, but it’s creating a new breed, not bringing back the old one.

To get the Being formerly known as the Auroch to revert to its old form, you would need time travel. Or cloning a new auroch from preserved DNA, Jurassic Park style.

Q. If someone nowadays figured out how to make a new Being, could there be a new Mouse? Or would it being dead not matter when it comes to that and it still technically counts as existing?

A. There could be a new Mouse, yes! It would be a newly-created Being from scratch, no relation to the original Mouse.

Q. Do Beings automatically learn their new Master’s language? Like, what would happen if Ilsa’s next Master only spoke, say, Japanese. Or would she just find someone who already speaks German? What about people who speak a signed language?

A. Beings are automatically fluent in the language(s) of their current Master. Their knowledge of the previous Master’s language(s) will still be strong in the beginning, and then start fading. So in this example, Ilsa would instantly know Japanese, and would remember German and English for a while, but lose most of it pretty quickly.

We’ve seen Patrick use bits of Arabic and German, because he used to be fluent, and still remembers a few phrases. He was jumping randomly between languages (Hebrew, German, Malachim, and English) when Cohen first met him, because he was between Masters and didn’t have a “default” language to settle on.

Sign language works the same way as any other — if the Master is fluent, the Being is fluent.
