"What does it matter?" said Malfoy. "Defense Against the Dark Arts – it's all just a joke, isn't it, an act? Like any of us need protecting against the Dark Arts –"
Who is Malfoy referring to when he says "any of us"? And why don't they need protecting against the Dark Arts? What is he getting at? Is he suggesting that anyone who fights against Voldemort won't wield Dark Magic? Is he suggesting that there is only one person or one group capable of wielding Dark Magic?
