I know a lot of people were miffed that Takatsuki ended up deciding she was not trans like Nitori, because they felt like it perpetuated the idea that its "just a phase" but I thought that was one of the best touches on the series. Because it's also important for people to know it's ok to not know right away. It's ok to explore your identity, especially when you're young, and it's ok for that identity to change over time. But I digress
