Sorry for the wait, I wanted to make this good.
Disclaimer: JK Rowling wrote seven amazing books. I have written the occasional story and have nothing published. I don't think we're the same person. Do you?
As the group from the future walked into the common room, Al noticed that Hermione, Fred, and George were sitting together.
Damn, Al though. Now they know, too.
The five of them hesitantly made their way over to the trio. James dropped into the seat next to Hermione and mutter "I see you overheard us?"
"Y-yeah," Hermione stammered.
"And you told the twins?" Lily asked
"Mmhmm."
"Would you like to take a walk with us?" Albus asked, thinking it'd be best to discuss this delicate matter away from the loud common room.
"Good idea," Hermione nodded, and stood up, motioning for Fred and George to do the same. "Lead the way."
James took the lead, marching the group out of the portrait hole, down a staircase and into an unused classroom. As everyone entered, James shut the door behind them. "Muffilato," he said, pointing his wand at the door. "There. No one should overhear us."
"How much information did you catch?" Rose asked Hermione.
"That you traveled forward in time, you're probably related to the Weasley family, and something about Fred dying."
"Pretty much everything, then?" Al winced.
"Well, we can't hide the truth from them now," James said with a grin. "Can't we just tell them?"
"Listen to James," Fred nodded, excitement building in his eyes.
"Yes, tell us," George agreed fervently.
Rose sighed, glancing at Al. "No way around this?"
"Not unless we use a Memory Charm," Al said. "And Fred, George, and Hermione all looked quite mad at the idea of us blocking their memories, so I doubt they'll let us do that."
"Fine," Rose grumbled. "We can tell them. But when we leave, Dumbledore will perform a Memory Charm on everyone!"
"How do you know?" Al asked curiously. "He never said that."
"Told me two days ago," Rose shrugged. "Asked me to tell you lot. I forgot."
James sniggered. "That rhymed. Lot, forgot."
Rose gave him a long glance before turning back to Hermione, Fred, and George.
"So, we're time travelers. A couple weeks ago, James, being the idiot that he was, pressed a button on a contraption we knew nothing about. We ended up here."
"And then we found Dumbledore, told him our problem, and he decided we'd pose as foreign exchange students from America during the tournament," Al finished for her.
Hermione looked interested. "Does he know a way to send you back?"
"He's working on it," Hugo said.
"Hold it," George said. "What about you being our family?"
"Yeah, you neglected to mention my death, too," Fred objected.
"Oh," Al glanced at Rose. "Erm-."
"All you need to know is that we are related to the Weasley family and that Fred does die at some point in the future," Rose said. "That's all. We don't want to prevent our births, so we can't give you excess information."
Fred paled considerably – he had hoped Hermione heard wrong. Oh, well. Everyone had to die someday.
George, on the other hand, felt like he wanted to puke. His twin was going to die in the future. He was going to change this.
"You called Fred your uncle," Hermione said hesitantly. "That means you have to have George, Ron, Bill, Charlie, or Percy for your dad. Or even Ginny as your mum."
"Oh, yes," Lily said. "One of them is our parents."
"Are you all siblings?" Fred asked.
"James, Lily, and Al are," Rose said. "And then Hugo and me."
"Hold it," Hermione said. It all seemed to be falling into place. "You," she pointed at Al. "Look just like Harry but with blonde hair. And your," she pointed to Al's siblings. "Names are James and Lily. Harry's parent's names. So you're Harrys' kids!"
Al glanced at James and Lily warily. This wasn't going well.
"And," Hermione said, realizing something else. "You're Fred's nieces and nephews. So Harry marries Ginny!"
Al nodded glumly. He had accepted defeat – Hermione was far too smart for them.
"Harry and our little sister?" Fred said blankly.
"But Ginny has a fan-girl crush on him!" George pointed out.
"She gets over it," Rose said impatiently. "Now, you have to promise not to tell anyone."
"Not even Harry or Ron?" Hermione looked crestfallen.
"Sorry," Rose said, but not unkindly. "But this needs to stay between as few people as possible."
"I suppose I won't say," Hermione said reluctantly.
"Us, too," George motioned to himself and his twin. "But we are going to change the future, because Fred cannot die."
"Yes, he can," Rose fixed him with a steely glare. "Because if he doesn't the whole timeline will be screwed up and some of our cousins won't be born."
"How do you know that?" Fred asked. He seemed to be taking his death much better than George did.
Rose, James, and Al shared a glance. They couldn't say that Fred's girlfriend when he died would eventually become George's wife.
"We just know," James said. "Please, try not to change anything."
"Okay," George said, but the look in his eyes said that they'd never give this a rest.
"So do you know what happens in the First Task?" Hermione asked. "Since Harry's champion and he's your dad."
"Erm, no," Al said. "Dad doesn't talk about his school years much."
"Why not?" Fred asked.
"Lots of bad things will happen," Lily said. "And talking about his years at school bothers him a lot – he says we're not old enough to know. But I'm eleven now. I have a right."
"Lils, Dad hasn't told James or me and we're fourteen," Al rolled his eyes.
"You're not fourteen yet," Lily said indignantly. "You have one more week!"
"Which basically makes me fourteen," Al rolled his eyes.
"Can you tell us who else has kids?" George asked. "And who they are?"
"Nope, sorry, not going to happen," Rose said breezily, making her way to the door. "I think we've talked about everything. See you later." She departed.
"I know it's a lot to take in," Al said in a low voice to Hermione as everyone else left. "But don't worry. It's not so bad. And soon you're headache will go away."
"How do you know I have a headache?" Hermione looked curiously at the younger boy.
"You're holding up your hand to your forehead," Al said.
"Well, thanks," Hermione said, and hurried out the door, Al in her wake.
"Well," Hugo said later that night in the common room. "That went well."
Hope you enjoyed! Sorry if it didn't live up to your expectations. Thanks for the reviews! Next chapter is the first task!
