From all the drama, one question in particular is really bugging me. I know McKay is naive, immature, and in desperate need of money, but how could she be okay with the idea of giving away her child—her own flesh and blood!
She thought at first it was insemination, so probably she thought the egg would come from the Luna, but even after he told her it would be the traditional way, all she could think about was the sex*al experience; she didn't even stop for a second to reconsider, knowing now they were asking her to sacrifice her own biological child.
