*spoilers* Becoming a Synthie (Sophie)
Little Sophie's antics lately of acting out as a synth...is it a phase? Or is she becoming a mini Synthie? It's kind of odd that the parents are already judging her and want her to be seen by a professional when they could just get down on her level, talk to her, and treat her like a child (warmth, stories, hugs). I don't see them doing that much with her. Mia/Anita seemed like more of a hands on parental figure - no wonder Sophie wants to be more like her.
Leo was also raised by Mia/Anita but he never became a Synthie. Granted, he is part synth already... And he's not exactly stable too. But that's more of a parental failure on his end.
