I like to believe that the nursery family becomes more and more a proper family as time goes by.
Carly is always Marjorie and Reece's work daughter, except the 'work' prefix slowly falls away through the years. Raising the twins heals something in the Knight siblings. Holidays and quiet nights in with Char's daughters heals Mia. The whole family joining around them heals Siobhan and helps her to move on from the trauma that Roger put her through as she continues to grow more comfortable in her place as Jamie's mum. Sorcha and Clodagh don't ever worry about Quinn being an only child because she has not only her Irish cousins but also her nursery 'cousins' and there's hardly a week that goes by without some large gathering of children.
The family dynamic becomes more real as one-by-one the kids grow into adulthood and find that the "OG Knight trio" (Aut, Reece, and Mia) have a small trust fund for each of them to make sure they all get a good start in their adult life.
