About Hermione in OotP (2007): "Hermione in this one is really about trying to take Harry out of himself. He feels very isolated and alone and he's kind of lost in a big way, so he separates himself from everything he cares about, which is Hermione and Ron because he thinks that's easier. And so Hermione's job is kind of to get him involved again and show him that he does have something really important to offer and that he can do great things. She gives him back his self-worth, really. It's quite an important role."
