"Oh, I'm not a metamorphmagus but my dad was one, It's only something that runs in the family, every time that we use very powerful and complexe magic or we get angry our hair start to change and it glows if you keep on performing magic more and more, but when I was a kid I used to have problemes with it till mum showed me a way to fix it, all you need to do is to separate your emotions from your metamorph stages and all will be fine, even you can start shifting it just by thinking of something, its very cool my father used to transform himself to stuff you can't even image."
