I had a very good reason to be mad, and I didn't get mad often. I got expelled for trying to make Ilvermorny a nicer place. Lily invited me to stay with her and go to Hogwarts from then, and Dumbledore approved, so I guess that was my only option, if I wanted to become an Aurologist and an Unspeakable. And now there were other people at this school that apparently needs someone to understand them. Something in my nature just leads me to try to help others as much as I possibly can. But it's hard when those people don't open up, and harder when you have problems of your own.
But if being in the most adventurous house of Ilvermorny has taught me one thing, it is that nothing is really actually impossible.
