y/n is harry s guardian angel. lily sent her.nobody knows, she doesn't want them to. it s the little things, when she jumps in to defend harry, when things go unexpectedly good, when things disappear so he won't trip on them,when the mood suddenly lifts when she enters the room or when the spells directed to him suddenly go into another direction or just simply dissapear into thin air. She has ginormous wings, those pure white ones that can cure people.
