That is such an awesome, empowering ending! It's so realistic, because if you have somebody bothering you about that kind of thing, they're not going to magically transform their minds. Maybe in the future, Christopher will come to terms with it. Maybe he won't. But the important thing is that Jacob understands that it's not Christopher's choice what he wears. It's up to Jacob. It's his body, and his clothes. He's proud of the dress that he and his mother made together.
