Re-reading Saga and one thing keeps bothering me - It is beyond belief that a wing and a horn having a baby is somehow special or shocking. In literally every war in history there are babies made from the opposing sides. Is the story supposed to be that there has never been a successful birth? Or a successful implantation because of species incompatibility? If so that's never really made clear, and if so it would affect characters' actions in the book much differently than what we see. There's no sense that this is some scientifically unique messiah baby, just hat no horn has ever had sex with a wing. Which is ridiculous.
