Like, think about it, what sort of sex ed would Shadow have gotten? His life aboard the Space Colony ARK happened over 50 years, so probably somewhere in the lates 1940s/early 1950. Sex ed didn’t start being taught in schools (in America) till 1978. Shadow predates sex ed classes. Not that it would even matter, since Shadow never went to any school, his education would’ve been aboard the ARK. And during that time period, talking about sex was extremely taboo. So then… did anyone aboard the ARK ever teach Shadow about the birds and the bees? Probably not, since the scientists would’ve planned for their living science project to just… never have sex, and they probably wouldn’t have wanted Project Shadow to have any offspring. They wouldn’t have wanted their living experiment making babies. So then, Shadow is probably naive af since he never got any sex education.
