This is one of the longest one-shots. I have another, similar, one that's around 7,000 words (this is around 3,500). I'll post that one eventually but it's similar to this one so I'm going to wait on it. ALSO: I ignore Cursed Child in all my fanfics and put Al in whatever house I want, which is why he's in the House he's in.

It was a busy but quiet day at the Potter household. Well, as quiet as it can be when the entire Potter-Weasley clan in one house, plus the two Scamanders and a Longbottom. They were all gathered for their Christmas celebration, which was why everyone was home. James, who was one of the pranksters of the group, was playing tricks on Albus, using a Wheezes product to get his brothers book from him. He hadn't counted on his younger sister tackling him to the ground, causing him to drop the book he had been levitating away from Albus.

"Woah, Lily, calm down!" The siblings broke out into a fight, nothing serious, just the usual bickering when Rose stepped in.

"HEY! Everyone shut up. Just shut up. We were trying to play a game before you decided to play tricks on Albus, and it's Lily's turn." Lily stopped suddenly and ran to take her turn. They had been playing a wizard-friendly version of Monopoly. It used fake currency and featured famous wizarding landmarks. Lily hadn't won a game against Rose yet and wanted to win this time.

Roxanne, who was also playing, started trying to trade with Lily, with Dom jumping in with counter-offers. A huge discussion broke out and Rose turned back to the game. James sighed and turned to Fred, who was also into pranking.

"What do ya say we go find something interesting to do." Fred nodded and they left the room full of people. The walked through the house, and James opened the door that lead to one of the spare bedrooms, where they saw Teddy and Victoire snogging. They slammed the door shut again and started laughing, the two were engaged and were still snogging in the most out of the way areas as possible. They dashed around the corner and jumped into a random room. James looked around and realized he had never been in this room before.

"Woah, this must be the artifact room. My dad usually locks this door. He must have forgotten to lock it in the rush to welcome you all." James was in awe of all the cool stuff, while Fred was getting his hands on everything.

"Sweet!" Fred grinned, but then they heard voices so he grabbed the closest thing to him and the two ran out the door. They had just made it around the corner when Harry came by and locked the door, sighing as he did. James and Fred waited for the coast to be clear and ran into the room full of kids. Teddy and Victoire were there, asking about the two sixth years. They walked in and the couple turned around.

"There you are! Did you ever hear about knocking?" Victoire asked while Teddy had one hand on her shoulder, trying to calm her. James, however, wasn't about to back down and argued with the older woman. The group of people playing Monopoly was staying out of it, with Rose staring even more intently at the board. Mid-argument, Fred threw his hands in the air in exasperation, forgetting he had something it in. Victoire stopped as the object fell to the ground. She didn't even have time to swear as it shattered on the ground and enveloped everyone in the room in thick blue smoke.

*Meanwhile, Potter Residence (AKA Grimmauld Place), 1995*

Harry was scowling at Severus Snape and the other Order members. They were still refusing to tell him anything. Even after what had just happened, they wouldn't tell him any more than they had already told him. He was about to open his mouth to argue again when the room filled with thick blue smoke and a group of sixteen people appeared in the middle of the kitchen, everyone had their wands out on both sides, but the small red-head was the first to lower her wand, followed by the two messy-black haired kids who looked like Harry.

"Dad?" And suddenly there were shouts of 'Fred' and 'James' chorusing throughout the group of kids. Mrs. Weasley was the first to react, making a loud whistle, which quieted all of them down quickly.

"Now, what is going on?" She pointed to the man with blue hair, who seemed to be the oldest as if telling him to explain.

"Well, uhm.. Seeing as there's no way to get out of this without changing everything anyway..." He took a deep breath, "We're from the future, don't say anything yet. We really are and we can prove it." Harry raised his eyebrow, and everyone looked suspicious but remained quiet.

"First off, is it after Christmas?" Harry nodded, "Ok then." He pointed to Harry, "That dream you had, about Gr- Mr. Weasley, you weren't an outside observer, you were the snake." He didn't miss a beat as he pointed to Snape, "You had a crush on Lily Potter and you still love her. In fact, you made a promise to protect Harry. Even though the whole thing is your fault anyway," He turned to Remus, ignoring the looks of shock Snape was getting, "You need to get over yourself and realize you like her," he pointed to Tonks, then Sirius, "I know you're innocent Sirius. Brilliant escape plan, by the way. Too bad Pettigrew is such a rat."

Everyone was stunned into silence, taking in what he had said when suddenly everyone on the other side was shouting. Again, Mrs. Weasley put a stop to it.

"Fine, it appears we believe you, which we do. Since you seem to know us, I assume you all are our future families?" Teddy nodded reluctantly, "Well then as long as you're here, I want to get to know you! I want to hear all of your names and who your parents are." It was clear she was trying to diffuse the rapidly building tension in the room.

"And your houses!" Sirius put in.

"This'll take a while, considering how many of us there are. But okay. My name is Teddy Remus Lupin. My parents are Remus Lupin and Ny- Tonks. I was a Hufflepuff." Tonks put her hand to her mouth while Sirius clapped the wide-eyed Lupin on the back. Then the woman that had been by his side stepped forward.

"I'm Victoire Molly Weasley, though I'm almost a Lupin... My parents are Bill Weasley and Fleur Delacour. I was a Ravenclaw." Mrs. Weasley was so happy she used all her willpower not to rush and hug her. Bill was wide-eyed, he was going to marry Fleur? Then a girl with bright pink hair and green eyes stepped forward,

"Dominique Apolline Weasley. Daughter of Bill and Fleur. I'm a Gryffindor." Mrs. Weasley smiled again. Then a red-headed boy stepped forward.

"Louis Arthur Weasley. Son of Bill and Fleur. I'm a Hufflepuff, and still mad that Fred and James went on an adventure without me." More smiles, and two apologies, as a set of twins stepped forward, both with brown hair and brown eyes.

"We're Molly Loraine Weasley and Lucy Anne Weasley. Our parents are Percy Weasley and Audrey Green." Molly cried at the thought that Percy had named his daughter after her. "I'm a Gryffindor," Molly said, while Lucy said, "Ravenclaw" Then a tan boy with reddish-brown hair and a girl with darker skin and brown hair stepped forward.

"I'm Fred Fabian Weasley. My parents are George Weasley and Angelina Johnson. My house is the one and only Gryffindor!" Fred the first turned to his brother,

"You stole my girlfriend!" They started play-fighting until the girl cleared her throat,

"I'm Roxanne Katie Weasley, also the kid of George and Angelina, and also a Gryffindor." A bushy redhead stepped up next.

"This will be interesting. Anyway, I'm Rose Marian Weasley... Well, uhm. My parents are Ron Weasley and Hermione Granger. Ravenclaw, by the way." Hermione was stark white and Ron was blushing from his toes to his hair. Fred and George were laughing and exchanging coins, while Mrs. Weasley was bursting with pride. Another redhead stepped up,

"Hugo Rodger Weasley. One and only son of Ron and Hermione and a proud Gryffindor." his parents still looked embarrassed.

"Don't worry Uncle Ron," said a black hair, hazel eyed boy, "You're gonna be angry soon enough. I," he said with a flourish, "am James Sirius Potter" Remus and Sirius both looked incredibly sad, but also happy, for Harry made it out alive, "The eldest son of Harry Potter annnndddddd Ginny Weasley!" Harry suddenly felt the stares of several Weasley brothers, and he could feel his face turn a red that could rival a Weasley's. Ginny looked no different and Sirius was laughing so hard Remus had to hold him up. "Proud Gryffindor, mind you," James added. When a replica of Harry stepped forward,

"I'm Albus Potter-"

"Hey, full name. We all had to do it." James said

"But my namesake is a total git!" Albus complained.

"Uh-uh. I'll say it if you don't"

"Fine. I'm Albus Severus Potter." It wasn't clear who was more upset about his middle name, him or Ron and Sirius, who were both outraged. Snape's normally straight face had dissolved into shock.

"You named your kid after HIM?" It was all Harry could do not to get mobbed.

"Hey, It was my future self, not me! I don't know the reason!" Albus cleared his throat.

"Anyway, as you may have guessed, my parents are Harry and Hermione" Every Weasley looked accusingly at Harry, who nearly fainted.

"Only kidding of course!" Harry glared at his future son, "Of course my parents are Harry and Ginny. I'm a Gryffindor as well."

"At least he didn't take after his namesake" Sirius muttered to Remus, who nodded. Then a younger, red-haired, brown-eyed girl skipped forward,

"I'm Lily Luna Potter, only daughter, and youngest you'll be pleased to know Uncle Ron, of Harry and Ginny. I am a Gryffindor as well." Ginny was still shell-shocked but managed a small smile at her daughter, and Ron was significantly less red after she was introduced. Then a girl with choppy brown hair and soft brown eyes stepped forward,

"I'm Alice Susan Longbottom. My parents are Neville Longbottom and Hannah Abbott. I'm a Hufflepuff." The kids smiled at the thought of Neville having a daughter, and another set of twins stepped forward.

"Lorcan Harry Scamander and Lysander Newt Scamander. Our parents are Luna Lovegood and Rolf Scamander. We're both in Ravenclaw." Harry looked shocked Luna named her kid after him and Ginny smiled.

"Well, I'm thrilled to meet you all! I think this calls for a dinner!" Mrs. Weasley set off towards the kitchen while everyone set off towards the dining room. Ron, who was still upset about Harry marrying his little sister, sat on the opposite end of the table. Mrs. Weasley walked in fifteen minutes later with a full dinner. Harry still didn't know how she did it, but he wasn't about to complain. Everyone was getting their food and chatting when Fred spoke up,

"So, how come I don't have any kids?" Several of the future kids stopped what they were doing. James dropped a spoonful of mashed potatoes onto the table and several of them dropped their utensils on the table. Mrs. Weasley knew what this meant at once and dropped the bread basket she had been holding, pulling her son into her arms, she was quickly followed by the rest of the Weasleys, besides George, who was staring at his twin, frozen in fear of losing his other half. Fred was staring at his twin between the many arms of the Weasley family. A deadly silence had fallen over the room, broken only by Mrs. Weasley's sobs.

"Who else?" Harry, who had been frozen in shock, asked, his voice hollow, "Who else dies?" Teddy sighed, and looked at Sirius,

"You die later this year, at the Ministry. " Harry looked at the man sitting next to him, Tonks and Remus had engulfed him and Harry was in shock, "The Dumbledore is killed at Hogwarts next year, and then it really goes downhill." Everyone seemed shocked that Albus Dumbledore, who seemed invincible, was going to be killed at his own school, "The war really starts after Dumbledore is out of the picture. Voldemort took over the school and the Ministry, and Uncle Harry, Uncle Ron, and Aunt Hermione had to go into hiding, they end up getting captured, but Dobby saved them. But Bellatrix killed him as they were leaving. My grandfather gets killed around then, and a lot of other people who opposed Voldemort. Then The Battle of Hogwarts happens, which is when it gets really bad."

"Battle of Hogwarts?" Sirius asked and Teddy nodded.

"Uncle Harry needed to go to Hogwarts, there was something there that helped defeat Voldemort. But Voldemort found out he was there and initiated the battle. Both sides had heavy losses, Colin Creevy died after he snuck back in to fight. Voldemort had Snape killed for... complicated reasons," Snape grimaced, "Grandma," Teddy turned to Mrs. Weasley, "You ended up killing Bellatrix after she nearly killed Aunt Ginny."

Mrs. Weasley was shocked that she killed anyone but furious that deranged woman came close to killing her baby girl. Ginny's eyes were wide with fear and Harry, who was sitting next to where she was standing, instinctively grabbed her hand in reassurance. Ron noticed and reddened, which caused Harry to notice his hand and drop it, but Ginny grabbed it again, glaring at Ron.

"But... before that, Bellatrix and another Death Eater," Teddy looked down, eyes watering. Victoire put an arm around him and tried to reassure him, "They killed my parents."

Remus and Tonks both looked at their son, shocked. They hadn't raised him?

"Who raised you?" Tonks asked, sadness clear in her voice.

"Grandma Tonks, but when I got too active for her to keep up with me, my godfather, Uncle Harry watched me most of the time." Tonks smiled and Remus thanked Harry for watching his son, "I'll tell you, I didn't make it easy for him, but I straightened out."

"So since you all are here, I assume we defeated Voldemort?" Teddy nodded.

"You gave everyone a scare Uncle Harry, you had to pretend to be dead to get the jump on Voldemort. Aunt Ginny nearly killed you afterward, but we won." Everyone was looking at the scrawny boy sitting open-mouthed at the table, eyes wide in shock. The silence was almost to the point of deafening when another cloud of thick blue smoke filled the room. Six people emerged from the smoke, the future versions of Harry, Ginny, Ron, Hermione, George, and Percy. The kids looked at the group of people and Lily ran over to them, hopping into Harry's arms,

"Daddy!" Harry chuckled, she may be twelve, but she was still his little girl. Everyone else started crowding the group of people, all trying to tell them what had happened, and how it was all James and Fred's fault. Hermione got everyone to calm down, and looked around at the scene, as did everyone else in the group. The shock couldn't mask the sadness in their eyes and Harry sighed.

"You told them about everyone, didn't you?" Teddy nodded,

"Uncle Fred asked why he didn't have any kids, and we kinda gave it away." Harry nodded and ran a hand through his hair.

"Well, then we might as well answer any questions you have since we're going to have to Obliviate you anyway."

"I have one." Sirius said from his seat, looking at Harry, "Why'd you name your poor kid after this slimy git?" He pointed at Snape.

Harry seemed to notice Snape for the first time, and he walked over to his old potions professor and regarded the man for a moment before he punched him in the face. Not hard enough to break anything, but enough to leave a bruise.

"That's for being a git." He turned to Sirius, "Well, he may be a git, but he used his last moment to save us all and risked his life every day. Besides, Neville wouldn't let us use his name."

"Well he is a Professor at the school, it'd be pretty embarrassing."

"That doesn't stop you from telling us to give him your love every year," Albus mumbled, but he was silenced with a glare from his mother. Then Fred, who had just stopped laughing at Snape, piped up, looking at Percy this time.

"When do you realize that you're being a massive git?" Percy, who was looking like his father in the hair department, sighed.

"Not until it was too late. I couldn't get the courage to face you until The Battle of Hogwarts. I was ashamed of myself, put up a front every time I saw any of you." The Weasleys looked sad at the thought, but happy that Percy was going to be part of the family again.

"What was with the whole on the run thing Teddy mentioned?" Harry asked his future self, trying to break the tension.

"Ah, that's a long story, see, Voldemort split his soul into multiple parts, and stored them in objects he considered important. You've already destroyed one of them, the diary back in second year. Anyway, after Dumbledore... died, I knew it was only a matter of time before Voldemort took over and I couldn't go back to Hogwarts. These two," he pointed to Ron and Hermione, who were sitting on his one side, "Came with me, which is good, considering I'd probably be dead if it wasn't for them. Anyway, we hunted down and destroyed almost all of them when I figured out he had one hidden at Hogwarts and we had to go there, which is where the final battle took place."

"But why did you have to pretend to be dead?" Ginny asked from her spot next to the younger Harry, and her older self shot a disapproving look at her husband.

"Well, it's complicated. In the simplest form, I had been inadvertently turned into a Horcrux and Voldemort had to kill me before he could be defeated. So, I went to the forest and gave myself up." Mrs. Weasley and past Hermione were in tears, "But I went to a Limbo, sort of, and I came back. But we were in the middle of the forest and the only way I could make it out alive was if I played dead, so I did."

"It was terrifying. We almost lost all hope, we thought he was dead, he was so still in Hagrid's arms." Ginny said, recalling the screams herself and many others had made, "But Neville inspired us and we kept fighting. Which is when mum went berserk. I'm sure you told them about that."

Teddy nodded, smiling.

"And we ended up winning." Harry finished, not wanting to drag it out. This brought up another flurry of questions, which those in the future patiently answered. Suddenly, future George, who had been eerily silent, got up and walked over to his twin. He looked him dead in the eyes and grabbed his shoulders.

"Never. Ever. Leave me without saying goodbye again." Then he hugged his much younger twin, who was still shocked but returned the hug. Everyone was much less on edge after that, and they eased into the more cheerful questions, such as when they had all gotten married, and what life was like for them.

"Hey dad," James asked, "How are we getting home?"

"We're leaving soon. Aunt Luna is working on it. She said something needs to happen on our side before it can happen, we're leaving first thing in the morning." James nodded, and then Mrs. Weasley noticed the time.

"Oh dear, kids, everyone off to bed, come now, it's much too late for you all to be up." Mrs. Weasley shooed everyone upstairs, even the future adults. It was going to be a long day tomorrow, and she certainly didn't want anyone tired.

The next morning, everyone was up and moving around. Snape had been forced to spend the night so that he couldn't tell Dumbledore what had happened, and he wasn't too pleased. But soon, after breakfast, the future Harry gathered everyone in one room and gave each of them a potion.

"This will make you all fall asleep, we can't let you see us once we Obliviate you, so this will prevent that."

"I don't get it, why don't we use this as an opportunity to change the future?" Fred asked, rather upset over dying.

"Time is a strange thing. We could change one small thing and change the future in a bad way. Changing the outcome of such a huge part of our past could change it in awful ways. I know that if Sirius hadn't died my fifth year, I wouldn't have been able to find the strength to fight back and show Voldemort he couldn't stop me from coming after him. It's all very complicated, and it's much better if we don't mess with time." Harry explained and told everyone to drink their potion again. Harry double checked to make sure everyone actually drank it, not just held it in their mouth, and the adults went to everyone and Obliviated the last twenty-four hours. Harry lead everyone into the kitchen, where Luna was standing, waiting to take them back.

"Well, let's go." Lorcan and Lysander ran to their mother and everyone gathered around her before disappearing into a thick purple smoke, back to their own time. Harry smiled as he left, neglecting to tell anyone he had left himself with the feeling of hope of winning the war.

This is also before I created Amelia as a character, unfortunately.
