Re: But... how can she have children if Vision is an android? THIS JUST KEEPS GETTING MORE AND MORE COMPLICATED!
Welcome to Retcon City!
Sure, sometimes all it takes is something simple (Fuckit, Hawkman died, he's now resurrected, almost exactly like his backstory is supposed to work!), but usually . . . you get an overcomplicated mess that no one enjoys, but stays canon because few people see a way out of it.
