"No, I think you like to delude yourself," he answered. "You still tell yourself that an expelliarmus won the war, but it didn't. A killing curse killed Voldemort. Just because you weren't the one to cast it, it doesn't mean that it wasn't the killing curse that did the job, just that you didn't do it."
He snorted. "Now, you think you send people out with a few spells and tell them to capture if possible, but the result is that they will die. Just look at the Hit Wizards at Hogwarts. So you like to think that we can play nice and not get slaughtered, then fine, but when people start dying don't expect anyone to listen to you anymore."
James stood up. "No, I knew you were going to complain before you even called. I told Severus to expect you. I knew it the moment I spoke to Moody that it was going to happen, so if you think this is subtle, it wasn't. In fact, I told him on Saturday that it would happen."
