They were still out there. Attacks and raids had ceased once all non-reformed Death Eaters were put in Azkaban. But they started up again in 2012, and Harry knew: this wasn't something that was going to die out. It was a generational thing. First in the 70s, then the 90s, now the 2010s-2020s. This war hadn't ended with it's leaders. He felt like he should have known. The Order hadn't dissolved with their own manipulative leader's death. Why would the Death Eaters?
This time it feels worse. They're being told not to fight. That these people that are protesting in the streets, the people everyone knows are behind the recent decrease in muggleborns aren't dead set on decimating half of the magical population.
Harry really doesn't want to fight. He's had is fair share of war, but he knows if he doesn't fight, his nieces, nephews, sons, and daughter will. He knows children will be forced to fight once more. Harry is well aware that they're going to anyway. But hopefully he can end this before they do. It's probably futile. Just like the first time he fought in this war, no one's taking him seriously. Students, teenagers, seem to be the only ones doing anything (not including his In-laws, Draco and his gang, Luna, or any of his Gryffindor dormmates. They were already gearing themselves up for a fight).
Teddy was following in his mother's clumsy footsteps and training to be an auror. Victoire was going to go into healer training next year. The oldest of them were already prepping for this. The younger ones (Dominique, Molly, Lucy, Louis, Fred, James, Roxanne, Al, Rose, Hugo, and Lily) were focused on learning magic to the best of their ability because they knew what had happened to their Uncle Fred. They knew what happened to Lavender Brown and Colin Creevey and Cedric Diggory and Regulus Black. And they weren't ready to die, but they weren't just going to sit around let their world fall apart. Not without a fight.
Harry gave a curt nod to Draco, who was bidding goodbye to Scorpius. Draco gave one in return. They wouldn't allow what happened to them happen to their children. Because children weren't soldiers and they shouldn't be treated as such. But as Harry saw the look of determination inside James' eyes, he knew it was too late. Once again the world rest in the hands of teenagers that didn't know what they were doing; just hoping they did the right thing.
They may not be able to stop their children from fighting and didn't think it was worth it to try. Because they knew better than anyone else that when no one is telling you what's going on in the world, you'll use dangerous methods to find out. This time, it wasn't their fight. The Boy Who Lived wasn't going to be the savior this time. Once again, a kid would be the one to end it. At the end of the day, it's the kids that know best how to handle it for this was the world they grew up in, so they would know better than anyone else how to end it. But the adults weren't going to sit around. They would allies and would fight the battles the kids could not.
As Harry bids goodbye to his sons, he knows all isn't well. But it will be.
