"OH I never said that I'd listen to her for you. I'm only going to defend you if wands come out," he said, with a snort. "She starts talking and you're on your own. I've heard too many of those lectures already."
Harry nodded. "I know. You had a crazy father who was training for a war that he made sure would never happen. I don't need to have lived through that to know. I come from 2003 and there was pretty much no dark magic activity. I know because I was bored out of my mind. I can't imagine that things got worse, not when people had lost all appetite for another war, especially after seeing that a bunch of kids had defeated the greatest Dark wizards around. So you might have learned the spells, but you never got to use them."
He sighed. "It's not your job, Jamie. If it's anyone's job, it's mine. I always thought it was mine, and guess what? I lost people. I lost a lot of people that I loved. When it comes to normal things, to feelings, then sure, protect them, but when it comes to war, and let's not pretend that this isn't a form of war, then no one can protect everyone. Things will happen. Look at Snape. If there's someone who can protect himself, it's him, and he got caught by surprise, first contact. Shit will happen, and this means that everyone will need to start training. For real this time. Not for some experimental ministry, but because we don't know what will come through next, and the best way to keep people alive isn't to protect them, but to teach them how to stay alive."
