Hermione notices the emptiness more than ever when she's alone. She is not a  we , not anymore. Not the way Ginny and Harry are, not the way she and Ron used to be. She loved Ron in her own way. He was her everything, her reward for years of hardship and pain. The answer to the family she lost (and in ways she felt she never had), someone to truly understand each part of her, both ordinary and extraordinary.
