I think people have asked about the book/adoption before, and I also hope it comes up again. It was answered with a we have not shown that yet kind of thing.
Basically most of the good questions we ask they cannot answer as it would spoil things. The fan panic stuff, well they can reassure people to watch. Then there are those few questions that are just clarifying something they meant to show, but maybe they edited the final cut in a way that made the scene less clear to some. So they will answer that (like Henry’s memory or time during the curse).
“If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?” -- Lewis Carroll, Alice's Adventures in Wonderland & Through the Looking-Glass
