darcy -- Olivia has health problems mostly genetically though April and her mothers family who has a history of several different kinds of things. Although partially it is due to April having been so small!
In our furry universe, there are hormones/medications you can take to "age up" a body to be ready for birth under the necessary circumstance. This can help numerous things in the world, but generally is to make it safer and more capable for the birth giver. However, most people even do this around middle school age or a little below, so 6 years old is a farther stretch! Still possibly, just meant there are risks which they knew about and prepared for :) (I really love building lore things like this)
Ruben does actually work! He's an architect, specifically commercial and residential. He's known as a pretty quiet type at his job and mostly works remote. People do see him as kind of... "The guy you don't want to be on the bad side of but ultimately a harmless, odd thing" haha. He's never really been the type to have people know what he's up to or what his personal life is like. I think the only time they could tell was when his marriage was going downhill and he was starting the divorce process. He'd work extra hours, show up exhausted or hung over or be late/close on due times- that kind of thing. Then there was the whole hush-hush "you okay buddy?" kinda shit and he's like "Yes."
Basically- he doesn't really ever have an opportunity to talk about his daughters or family and he likes it that way. He's very upfront and confident and loves a good debate or argument, so he often spares himself what he sees as "inferior, frustrating" convos by just avoiding personally talking.
