The only person in my head is me.Tibe is not the same. The crown has changed him, as you feared it would.The fire is in him, the fire that will burn all the world.And it is in your son, in the prince who will never change his blood and will never sit a throne. The only person in my head is me. The only person who has not changed is you. You are still the little girl in a dusty room, forgotten, unwanted, out of place. You are the queen of everything, mother to a beautiful son, wife to a king who loves you, and still you cannot find it in yourself to smile. Still you make nothing. Still you are empty. The only person in your head is you. And she is no one of any importance. She is nothing
