Episode 14 has a small, not unfixable plot hole.
We have a girl who is being kept prisoner, and has been a prisoner since she was a baby. She gets one day in which she goes to the outside world for the first time. She presumably doesn’t have any pocket money with which to get wrapping paper.
Nonetheless, she presents her beloved caregiver with a wrapped present. Even if she didn’t have to buy anything – even if the contents were leaves and rocks gathered from the yard – where did she get the wrapping paper?
That being said, this episode has a lot of good quotes, such as the one below.
