Why does any child have to be destined for fame? They’re average kids with average talents. Nothing terrible, nothing amazing.He is pushing the whole being child actors narrative so hard, it's going to land the Es in such emotional turmoil when either it doesn't happen or they decide they don't actually want it and have to disappoint their father.
I disagree that Alessia has what it takes not in terms of talent, who knows, but she has never given any sign that she enjoys performing or being the center of attention or anything. I for one hope that the silver lining of them always ignoring her is that she can grow up more normal and decide for herself what she wants to do without the insane pressure from Anna and Jono to perform like some sort of circus animal.
