I literally live for alternate fics where the war lasts longer, where Harry loses, etc.

So this is another of those.

...

"This won't go the way we want it to." Kingsley said, appearing behind them. A second hour of peace had been called, and Harry was trying to regroup with people, trying to figure something out. When Voldemort realised that he could die, and that he no longer had Horcruxes, he called for the hour, demanding Harry turn himself over and he'd allow the battle survivors to live. Harry had told people what he had seen in Snape's memories, but no one was about to let him walk up to Voldemort and sacrifice himself.

The snake was dead, and that was good. Neville had managed to pull the sword from the hat when the hat had been found in the Great Hall, and at some point- amidst the dying and screams and duels, he had killed the snake.

"We need to keep fighting." Tonks said but Kingsley shook his head.

"I'm sending people out of here. If there's no one left to fight, we can all live. Go home to Teddy, leave the country." Kingsley said steadily.

"We can't just leave." Tonks said, frowning, but she could tell Remus was considering it. "Remus, no."

"We're not Aurors anymore, so I can't use the senior Auror rank to get you to do this." Kingsley said to Tonks. "But as a mother, you should want to."

"We'll send a message from wherever we end up, we'll let you know we're alive. You do the same." Remus said, reaching out to shake Kingsley's hand.

"You can't be serious." Tonks said. "Leave the fight? Leave the war? Leave Harry?"

"Harry will leave as well." Kingsley said. "I'll make sure of it. No one will be left here to continue the battle. The Ministry will be weak right now. You can use Portkeys, and they won't track you."

Kingsley turned to walk away, but Tonks grabbed his arm. She threw her arms around him, hugging him tightly. "Stay safe, King." She whispered. And as she stepped back, Remus took her hand. The last thing she saw as the Great Hall disappeared was Harry watching them. But he didn't look angry, he looked like he understood. She could only hope that he did.

25 Years Later

July 15th, 2023

"Teddy Lupin!" A voice shrieked, storming down the stairs. 16 year old Charlotte Lupin appeared, her hair a bright red- but not by choice. The second child, only daughter, of Remus Lupin and Nymphadora Tonks had not inherited her mother's abilities but had been unfortunate enough to inherit her father's condition.

"What's going on?" 50 year old Nymphadora Tonks asked. She appeared around the kitchen door to meet her daughter at the foot of the stairs. Despite being 50, she certainly didn't look it. She had a few grey hairs, ones that she wouldn't morph away. And although they had been in Maui for nearly 25 years, her parents still had slight traces of their home accents.

Tonks sighed at her daughter's hair. "Char, what had we said about Muggle hair dye?" Tonks asked.

"It wasn't me! It was that asshole!" She said, pointing to her older brother who had just entered the house.

"Language, Charlotte." Tonks said sternly.

"What did I do?" Teddy asked, and then he spotted her hair, and began to laugh. "That wasn't me! I was at work all night, when would I have done that?"

"Oh, that was me." A voice said from the door. 63 year old Remus Lupin leaned against the door. He definitely looked his age, if not older. His hair was completely gray, his face lined and scarred but he smiled like a school boy at his daughter's discomfort.

"Dad? What the actual Hell!" Charlotte cried. "Why?"

Remus simply shrugged. "It'll wear off in a week." He responded, disappearing back into the kitchen. Charlotte went to follow him, but her mother stopped her.

"I will talk to him. Teddy, try some charms to help her fix this. If anything, transfigure her hair to a softer red if you have to." Tonks said calmly.

It was then that an owl swooped in through the living room window, dropping a letter at Tonks' feet and sweeping back out. Tonks bent down, scooping up the letter, and opening it.

"It's from the Order." She said, more to Teddy than Charlotte. "Teddy, kitchen. I need to talk to you and your father."

"Right away, Ma'am." Teddy said, giving a mock bow and following her.

Charlotte rushed to put her ear against the door. She knew about the Order, she had heard the story of why her parents had come to America instead of staying back home. The Order usually only owled at the beginning of the month, never the middle- it was a good way of ensuring no one was sitting around too long waiting for a letter about someone's current survival status. If no letter came by the 10th of a month, it could be assumed the person meant to send the letter was dead.

She remembered when she was 9, and her mother had been awake for nearly five days waiting for a letter. It had never arrived, and she had cried for a few more days. Charlotte never knew who died that time, but she did hear her mother say something about a king.

She listened intently, but only picked up a few words: home, war, battle. She also caught something that sounded like Thank god that bitch is finally dead, from her mother and she gaped at the door. Her mother never wished death on anyone, who could have pissed her off so much?

"Should we pretend Char hasn't been listening this entire time?" Her father's voice asked, loudly. Charlotte felt her cheeks flush pink. They knew her too well, she supposed.

The kitchen door swung open, and she trained her light green eyes on her father's light green eyes.

"Come on, Charlotte, we need to talk." Remus said, stepping aside and letting Charlotte in the kitchen.

So for reference, for both me and you(reader), here is a list of character ages in this. It won't be a long list, of every character. If I missed a character, they might be mentioned later:

Harry/Hermione/Ron: 43
Twins: 45
Bill: 53
Fleur: 46
Tonks: 50
Remus: 63

Kids:
Teddy Lupin: 25
Victoire Weasley: 23
Dominique Weasley, Fred Weasley II, George Weasley II: 21
Roxanne Weasley, Louis Weasley, James Sirius Potter: 18
Charlotte Lupin, Albus Severus Potter, Rose Weasley, Scorpius Malfoy, Lucy and Molly Weasley(II): 16
Lily Luna Potter, Hugo Weasley: 14

I think that's all the kids, plus Charlotte. For adults, their ages will be mentioned as the story goes, because this would be the neverending list otherwise and they might be dead so age wouldn't matter there. So basically, the next gen kids are still all born, raised in hiding, sent abroad for schooling because the only one who can go to Hogwarts would be Scorpius and the Ministry might not know these kids even exist.
