With Cade Skywalker sleeping around with a good number of people just on the page so far (Deliah, Azlyn, Darth Talon), there's a good possibility that Deliah (or some other near-human) could get pregnant with a Skywalker baby for the next generation. For all we know, there are already a dozen unknown Skywalkers scattered across the galaxy. But even putting that aside, if Deliah were to get pregnant, would we the audience be willing to accept a near-human Skywalker? Could we accept future Skywalkers being Zeltrons? Or some other near-human species? I mean, we haven't even seen any Skywalkers that aren't white European humans. We haven't seen any black Skywalkers or asian Skywalkers. For some reason, that seems taboo. So could readers really accept the future Skywalkers being Zeltron, and not even 100% human? Even though Zeltrons are (or at least appear to be) just another (fictional) ethnicity within humanity? (I never understood why so many near-human species aren't considered human, but "near human," but that's a whole other topic).
