This is more of a thought for the long-term - when the MC gets formally married to a founding family daughter.
I wonder if that founding family will embrace the concept of the dowry for the bride to be - as a matter of showing the 'value' that their daughter brings to her new husband (and that founding families hoped for ally on the council)?
This could create a bit of a competition to see who gives the 'best' dowry - given that the MC will have wives from the other four founding families (I'm counting Elizabeth Russell here) - which founding family wants to be shown as cheapskates, after all...
(I realize that, at present, Catherine's family is all but owned by Sarah's father, so that leaves 3 founding families with the means to compete in the dowry offered with their daughter.)
I don't know if Cosy will tell the story out this far into the future, but it struck me as another aspect of the founding families and their interrelationships/competitions with each other.
I think we will see the beginnings of the 'value' of favors from founding families in the aftermath of the upcoming Tuesday council vote where the MC will oppose every vote by Hannah's father.
It will take a few episodes for the 'favor effect' to begin to play out - likely taking us up to Friday or into the weekend - but it will be an interesting 'spice' to add to the main course of the time the MC spends with his women and how they further meld into the beginning of his harem.
Cheers!!
