Hawthorn actually is not afraid of much. She's been through a lot of trauma, but has emerged stronger from it. I suppose her greatest fears are her temper or lack of control on her predatory nature, being forced to kill in self defense, having offspring who will be bullied for being halflings. Her more day to day fears are accidentally losing control of her pyrokinesis (since it's a woodland area) and spiders, funnily enough!
