No, poor Squishy.
It's so sad! He needs a little comfy bed and a blanket to wrap up in and someone there to just pet his head and say everything's gonna be alright, poor Squishy poo.
Wow, that's much worse than I was fearing. And all of the ones we've met so far are direct decedents of Nel (Serinar, Dannathion, Siderion, Nameria, Ruthian).
It's probably even worse than this: the Red Dragonflight waged a genocidal war against the black dragonflight, specifically targeting all potential broodmothers. Wrathion also participated. So even assuming the remaining individuals are fully unrelated (unlikely) there are probably only a couple females tops in the remaining 15.
With 2 females there are only 26 potential reproductive pairings between unrelated dragons. Throwing in Nel only raises this to 28. There are also only 92 potential non-reproductive pairings that could improve social stability among these (hopefully) unrelated dragons.
I'm confused. The population model in the other journal showed how even in a species with binary gender, same-sex attraction isn't necessarily an issue even in fairly dire circumstances.
However, the binary gender model doesn't appear to apply to the Warcraft dragons at all, so even that isn't an issue. Since dragons appears to be culturally, instinctively, and biologically capable of handling multiple mates & consorts, a non-reproductive relationship doesn't come at the expense of a reproductive relationship. There no need to wait for "stability", as there's no cost to these interactions, only benefits in terms of stronger bonds within the flight and stronger offspring in general.
Ultimately, Nel's problem is even bigger than just the fact that his species is on the brink of extinction. A dragonflight was more than a species— it was a community, a culture, a civilization. He needs whelps badly, but he ultimately need more than whelps. He needs broodmothers and broodfathers, teachers, healers, historians, fighters, warders of the earth, etc. He needs a strong interconnected flight that trusts and can rely on each other, which can confront the enormous challenges they face as a unified force.
Having offspring is necessary, but not sufficient: the offspring must survive, they must learn to be true black dragons, to avoid the corruption, regain their culture and fight for their place in the world. This requires a strong flight. This requires strong bonds between the remaining dragons, in addition to the need for more offspring. So anything that starts to repair the mate / consort bonds, engender trust, and strengthen the relationships is a step in the right direction.
Of course, this is all pretty much a moot point for Neltharion and the Black Dragons we've seen so far. All of the ones we've seen are closely related to Neltharion and to each-other, so they're all probably culturally, biologically, and instinctively ineligible to be mates or consorts to each-other regardless of gender, for rather obvious reasons.
