"Oh," he said thoughtfully. That was actually interesting. He didn't know all that much about human culture, he realized, and Link's words had definitely come as something of a shock. "Does that mean you can't reproduce with others of the same gender? We, um... bloodlines are strange, because generally trolls never see the people who conceived them. Fertilization always happens in an external source, and the genetic material gets kind of... mixed together, to see what happens, so no one really knows how related they are by blood to another individual. I mean, some highbloods think that there are others who have identical genetic material to them somewhere else in the timeline, and they are related more intimately that way, but... well, we're not really sure if it's true." That last sentence was the polite, fearful way of saying 'they're just doing it to make themselves feel special'.

Also, don't worry if you don't speak much, Link. Get Equius on a topic (or sufficiently upset) and he never shuts up.

"...Wow. Uh. I'm sorry, I... sorry." Pause. "Equius Zahhak."
