I agree! I hate when they do the carbon copy thing. They could have at least given the son the silver hair and Adele's eye colour, that would have looked nice! The baby girl was more of a mix having purple eyes with her red hair but still, I wish there was a better switch up :')
That isn't as in natural as you may think plenty of children end up looking like a carbon copy of one of their parents. Some even end up looking like the aunt's or uncles or grandparents from one of the parents sides. Genetics can't be predicted so it's entirely possible to have two children that are carbon copies physically to their parents. Often they even share their parents personalities, like the Duke's son may look like him, but he acts like his mother. And their daughter may look like her mother, but she seems to have her father's personality. These are all NATURAL traits, and perfectly NORMAL.
Why didn’t the author at LEAST switch up the hair colors of the children?! They look like carbon copies of the parents which is very unnatural!
