There's a serious question about Adult Shadows that I thought of: Is it possible for Adult Shadows to reproduce with eachother? I mean the children can even get engaged so they can get married when they become adults,there must be a reason for that, nearly anything in the Shadow House has its causes and reasons
What are the possibilities for a male adult and a female adult, both are perfectly unified with their humans, to get married and then decide to reproduce?
I mean would the child born from two unified shadows can be like Kate? Born with a human look but ended up turning into shadow when they get older,hell they can even turn their appearance to human form at will due to their parents being unified shadows. Then we are also left with the question which is can Shadows even reproduce?
Also I don't really think that even if Unified Shadows can reproduce,the Shadow House would stop recruiting children, after all those soots ain't gonna make themselves and they do need money gained from soot production to fund the spendings of many aspects (infrastructure, logistics of food and clothing,etc) and ofc the lavishness of noble lifestyle too
Sophie literally has a butterfly wing attached to her outfit and I'm pretty sure she ripped the wing by accident more than once, which means money is needed to get a new wing or to repair the wing
It's interesting to think about,after all if there's a character who are born from two unified adult shadows. It would be hella interesting honestly. Like how can they explain to other child shadows that Mommy and Daddy are shadows and that they don't have a Living Doll because they already have a face. Oh!!! What if there is an entire Shadow House to cater for that,where offsprings of unified shadows are put there, separated from the shadow children who are born from morphs that mimic the human children?
First of all, that's honestly a question that I have at the back of my mind for a long time!
You did pretty well on breaking down the possibilities. I must admit that for the engaged-married situation, my first thought is that they're just doing so because that is what humans do. Humans marry each other-- It will make them become more human-like.
For the reproduce part, if Shadows do reproduce sexually, I think it's a various level of fucked-up, considering that their bodies are basically corpses of dead humans (sort of, it's very much unclear). And I have always been curious about how do Morphs even reproduce, because not even Shadows know how do they originally came to be as Morphs.
If there are Shadows that are born from two unified Adults, I think they will either be treated in a slightly higher hierarchy, or as an experiment to see what kind of Shadows would be born. I do think that last part is a possibility, or could be an AU in itself!
