Hadley is ENFP-T.

Extraverted, Intuitive, Feeling, Prospecting and her identity is Turbulent...

Yeah, I'd say that fits her...

I kinda didn't like the term Campaigner to describe her though, until I realize she literally does campaign, in her own messed up way, for things she wants. Like starting Animagus training.

Not all of the description fits her, but I have a feeling that it's in part because she's 13. I can see it fitting her fully as an adult.
