Prank 1

Introduces a bit of Wufei and a lot of Quatre. The first prank (which should not be repeated by anyone. EVER.)

The only reason it was updated so quick was because I already had this prank in mind (and because I've done this before). Future chapters will take about a week to upload (I'm sorry). If you have any prank suggestions, that are muggle, feel free to share them. I have a lot of plans for wizarding pranks; thoughts on wizarding pranks are welcomed as well!

This would have been up yesterday but the site was being stupid and not letting me upload. My apologies.

The room was beginning to show signs that two boys were living in it and Harry's inner germaphobe was beginning to protest. He looked over to the scattered books and the dirty clothes lying on the floor and inwardly flinched. 'How did we make so much damage in two days?' Harry wondered as he picked up some of the dirty clothes and put them in a pile so that he could throw them into the washer later. He started to put all his schoolbooks back in the trunk when Duo came into the room with a towel wrapped around his hair and an armful of dirty clothes.

"You really don't like messes do you?" Duo inquired as he sat on the bed and watched Harry clean. He looked over to the pile of dirty clothes and threw his armload on it. "Where's the washing machine? I can do the laundry."

Harry looked up and nodded as he pushed the pile towards him with his foot. "It's in the basement. Put on shoes before you go down there, though. That place hasn't been cleaned in a while and Dudley has dropped a lot of bottles when he's trying to hide them from Aunt Petunia."

Duo nodded and put on his trainers in a hurry. He looked at the pile and tried to make it as small as possible as he squeezed it to his chest. He was able to get all of them after many grunts and some help from Harry and needed to maneuver his way through the door. Harry continued to tidy up the room in Duo's absence with mutters under his breath about how he had been careless to get everything messy.

Beep beep.

Harry hummed under his breath as he straightened out Hedwig's corner and made sure that she had clean newspaper in her cage. He wrinkled his nose at the dirty water and empty food bowl and took it out.

Beep beep.

He looked up and around him to try and find the thing that was making that noise. When the sound didn't happen again he shrugged and went back to inspecting Hedwig's food bowl. He shuddered as the water sloshed around and carefully ran out of the room and into the bathroom to properly clean and refill it.

Beep beep beep.

Harry's eye twitched as the beeping started to escalate to new heights of irritation. He looked around him and stood completely still to be able to pinpoint the whereabouts of the noise the next time it beeped. Beep beep. His eyes zeroed in on Duo's bag and he walked towards it cautiously. He had heard some mutterings around the neighborhood yesterday about explosives and he knew that he shouldn't be suspicious of Duo but what if someone had put the explosives in there? Duo could get hurt and Harry wouldn't be able to get to know him like he had planned.

He looked around him to make sure that no one was watching, which was odd because his aunt had gone to a book club meeting, his uncle was working, and Dudley was terrorizing the neighborhood kids. He unzipped the bag and looked inside. There was a rectangular, flat box blinking green and red and as he touched it and moved it around he noticed that it was a laptop. He put it back inside the bag when it beeped again and then thought better of it and took it out again.

"Will he be mad if I bring it to him?" he asked himself as he looked at the black surface with a frown. "I had to go through his things to get it. Is that a breach of trust? Would be okay because I was just trying to be helpful or would he still get mad?"

"Will who get mad?" Harry whirled around to stare at Duo. "Is that my computer?"

Harry looked down at the computer in question and nodded. "Yeah. It was beeping so I was going to go give it to you. I didn't know whether or not you'd be mad if I look through your stuff…" Harry trailed off as Duo grinned and bounced his way to Harry.

"How many times did it beep?" Duo asked as he sat down on the bed and looked up at Harry.

Harry looked at the blinking numbers and then at Duo. "It beeped twice and then it would stop. Then it would beep twice again later. It did that about five or six times; I wasn't really paying attention."

Duo nodded and looked through his bag as he flipped open his computer. He put on headphones and clicked some keys. "Is this important?" Duo asked and Harry wondered if he was talking to him and turned around to continue cleaning. "Excellent! Do you want to meet my older brother?"

Harry didn't have time to turn around as Duo grabbed onto his arm and yanked him down to sit next to him. Harry glared at Duo but sat closer to him to look at the screen. There was an Asian boy staring back at them and he didn't look happy as he rubbed his temples.

"Um, hello," Harry said with a wave near the computer screen. The computer white noised for a while and Duo winced and took his headphones off. Harry took his hand away and the computer returned to normal. "Sorry. That wasn't intentional."

Duo blinked and then did the same thing that Harry did with no reaction. He grabbed Harry's hand and the computer white noised again. "That's awesome! I've never met someone that can do that!"

Harry rolled his eyes and looked at the screen. "Things have never short-circuited around me before but they have a tendency to temporarily stop working."

"It's like you have too much electricity in your body so your body starts messing with electronics," Duo said with a wide grin that had the Asian boy shaking his head and rubbing his temples. "Can you do that, Wufei?! Of course you can't!"

Harry covered his mouth and a snort managed to come out as he tried to hold in his laughter.

"Maxwell, I'll tell Winner and Yuy that you're alright," Wufei commented as he looked away from the screen. The screen turned black and a new screen popped up.

Duo grinned and looked over to Harry. "That was Wufei, he's a friend of mine. He isn't very talkative but he's a really good friend. You can't ask for a better friend than him."

Harry smiled and nodded and continued to rummage around the room to make sure that everything was nice and tidy. "It's always good to have friends like that," he mumbled as Duo closed the computer and put it on the bedside table. "Do you have anything in mind for dinner?"

Duo perked up at the mention of food and hummed as he thought. "Pasta!"

Harry nodded at the suggestion and rolled his eyes at the energy. "How is it possible for you to be so happy all the time?"

"Why shouldn't I be happy?" Duo asked as he followed Harry out of the room. "I mean, I've got you, and that's something to be happy about. Not to mention that you promised that I wouldn't have to stay with this pack of zoo animals after your birthday. You are taking me with you, right?"

"I'm taking you with me," Harry said with a reassuring smile. "It'll take a while for you to get used to the differences between the houses. There's no electricity and your computer will probably not work there."

Duo's face paled and his mouth dropped. "An electricity dead zone? Is there an internet café anywhere near the house?"

Harry shrugged and laughed at Duo's dejected look. "I'll see what I can do about the electricity; I make no promises about Internet or anything extreme."

"Where's the house anyway?" Duo asked as he sat down at the table. "There has to be a place around it."

Harry winced and tried to answer. "It's in London. It's sort of a safe house, or headquarters type of place. I was thinking of getting an apartment around it, with electricity, but I don't think I'm going to be allowed because I'm not eighteen."

Duo looked at Harry and grinned. He looked over to living room where Dudley was playing some videogame. "I can look up apartments for you. If I just talk to the right people I'm sure you can get a place no matter your age."

"Is that legal?" Harry asked with a frown.

"Probably," Duo said and looked away from the green eyes, "not."

Harry didn't know how it happened but one minute he was putting the chicken in the pan and the next he heard moaning from the living room. Loud moaning.

He looked up and his eyes locked with Duo's and then his aunt's. There was another loud moan followed by other noises that had his face turning red. His aunt's jaw dropped and covered Dudley's ears as he turned around to stare at the living room where his father was trying to turn off the TV and having a hard time of it. Duo had a brow raised and he was trying hard to not laugh at what was going on in the other room. There was a scream of ecstasy and Harry flinched as his aunt pressed Dudley's ears even harder.

Petunia glared at the other two boys in the kitchen and opened her mouth. "Out, out, out! Don't come back until it's dark, you hear?" she pushed Dudley and the other boys out the kitchen door and slammed the door closed. Dudley looked at the door in confusion and then over to his snickering relatives.

"I'm going to Piers'," he said giving the house one last look and a sneer to his younger cousins. "I need to eat something."

Harry shrugged and made his way over to the local playground. He sat down on a swing and waited for Duo to sit next to him before he could speak. "What was that?"

Duo couldn't hold in his laughter in anymore and laughed out loud startling Harry from his musings. He held onto his sides as it became harder for him to breathe. He wheezed some more as he wiped tears from his eyes. "God, that was some good entertainment. Who would have thought that it would turn out like that?"

Harry looked on in confusion as Duo continued to laugh. "Did you know that was going to happen?"

"The good ole 'put porn on and turn it off' trick. It's a classic, Harry," Duo said with bright smile. Harry rolled his eyes but let Duo continue to explain how he had done it. "It was kind of complicated to get it to not turn off, though; I think that was the only hard part but I managed to do it by changing some of the configuration on the remote."

Harry raised a brow at his explanation. It really all just went over his head since he didn't know anything about the workings of a remote or a TV; he just knew that they worked. "I can't believe you did that, Duo," he mumbled as he shook his head. His stomach growled violently and he looked away with a blush.

Duo bounced up from his swing and started to pull Harry away from the playground. They walked passed Magnolia Crescent and Harry frowned as Duo continued to lead him farther and farther away from the playground and farther away from the blood-ward protected Number Four.

"Where are we going, Duo?" he asked as they stopped to let a car cross. "Aren't we getting a bit farther away from Number Four?"

"Yup. We're going to visit a friend of mine," Duo chirped as a taxi stopped in front of them. He gave the taxi driver an address that Harry wasn't familiar with and smiled brightly. "Don't worry so much, Harry. Quatre's the nicest guy ever. He's staying here for a couple of months to deal with some business that came up."

Harry watched the houses whizz by and watched as they became farther and farther from each other and bigger and bigger. He looked over to the happily smiling Duo with a raised brow. "Where exactly does your friend live?"

The car stopped in front of a giant black gate and Harry stared at the huge house in front of them. Duo paid the driver and waited patiently for Harry to get out. "Welcome to one of the Winner estates."

Harry looked at the house and then over to Duo. "Bloody hell, this place is huge."

Duo rang the bell in the gates and looked into the camera just above it. "Yeah. Quatre's really rich and he owns properties all over the place. This is just one of the bigger ones."

"Yes? Can I help you?"

Harry jumped at the voice and looked at the speaker and the camera. Duo grinned and stepped forward. "Hi, Rashid! It's Duo Maxwell, is Quatre home?"

There was some static and the gates opened. Duo didn't wait for the gates to open more and started to pull Harry up the large driveway. In the distance Harry could make out the door opening and a huge man opening the door and smiling at them.

"Harry, this is Rashid Kurama, he's Quatre's bodyguard," Duo said happily and Harry looked up and up at the man. "Rashid, this is my older brother, Harry Potter."

Harry smiled and said hello as the man ushered them inside. "Master Quatre has been hoping that you would come visit," he said as he started to climb the stairs and looked back at them. "He's been eager to meet your brother, Master Duo."

"Of course, who wouldn't be? Harry's awesome," Duo said with a grin as Harry rolled his eyes and shook his head. His cheeks turned pink at his brother's excitement and he scratched the back of his neck while Rashid looked him up and down.

"I'm not that big of a deal," he mumbled as Rashid knocked lightly on a grand door. Rashid ushered them inside and Harry was a just a bit shocked to see a teenager at the giant desk of the study.

"Kat!" Duo yelled as he rushed around the desk to the blonde to give him a hug. "It's been ages since I last saw you."

The blonde's eyes widened at the action and slowly brought his hand up to pat Duo on the back cautiously. "It's nice to see you, too, Duo. Are you feeling alright?"

"I'm doing great, Quatre," Duo said as he backed away from the blonde and made his way to Harry's side. "Wufei told you about Harry, right?"

Quatre walked around his desk to stand in front of it. "He mentioned him, but you know how Wufei is. All I know is a name."

Duo put an arm around Harry's shoulders, which was an awkward position because Harry was a bit taller than his brother. "Turns out that I have an older brother. This is Harry Potter. Harry, this is one of my friends, Quatre Raberba Winner," Duo and Quatre waited for the reaction and were shocked to see no reaction.

"It's very nice to meet you, Quatre," Harry smiled as he shook the blonde's hand.

"Wow, you really do live under a rock," Duo said as he eyed Harry over with a frown. "You didn't even have a reaction at his name."

Harry's eyes widened as he looked over to Quatre. 'He's some kind of muggle celebrity isn't he? Bugger, why didn't I tell Duo more about magic and my lack of muggle knowledge? Argh!' Harry thought to himself as he looked between the two confused looking teens. "Sorry about that. I don't watch the Telly all that much and I've noticed that gossip is all that papers have nowadays."

Quatre smiled, nearly catching Harry off balance with how relieved he looked at that. It was the same look he gave to anyone who didn't immediately look at his forehead. "It's a pleasure to meet you, Harry. How about you two join me for lunch? You can tell me more about your first week together as siblings while we eat."

"Is Duo the prankster in your group of friends?" Harry asked as they made their way back down the stairs.

Quatre raised a brow and then looked over to Duo. "What did you do, Duo?"

"It won't leave any permanent damage! I even managed to not explode anything!" Duo said as he stepped away from the blonde and decided it would be safer to walk beside Harry and not Quatre. "I'm hoping Harry will join me," Duo said as he hopefully looked at Harry with his lower lip sticking out and quivering. "Pleeeease?"

Quatre sighed and shook his head. "Can't you at least try to get along with your relatives?"

"You wouldn't be saying that if you lived with them," Duo mumbled with a pout. "Can you think of any pranks to do before the end of the month?"

"What's at the end of the month?" Quatre asked as he opened the door to the dining room. "You aren't planning something illegal are you?"

Duo shook his head and wrapped his arm around Harry. "It's Harry's birthday."

"Oh, really? Are you planning anything for his birthday?" Quatre asked as they sat down on the huge table. "I'm sure Duo won't do anything that will long lasting," he said as he tried to reassure Harry.

Harry smiled and nodded at him. "I don't think he had any plans on pranking me. I could very easily turn the tables on him. I am the son of a Marauder, after all."

"Marauder?"

"Our father and his friends had this group back when they were in school that called themselves Marauders. They used to prank everyone and there's a legend that they left behind a book of pranks," Duo said as his eyes widened in excitement. "Do you know the things you could do with a book like that, Quatre?"

Quatre looked over to Harry for confirmation and the green-eyed teen nodded. "I'd have to ask Remus, the remaining Marauder, whether the book actually does exist or not or if it's just a hopeful thought from the Weasley twins."

"You like pranks as well?" Quatre asked as he raised a brow at Harry.

Harry nervously laughed. "I'm not really a prankster. I've had too many pranks pulled on me from my best mate's twin brothers. I've tried to prank them back but they always know how to avoid it. I'm more of an explorer than a prankster."

Duo pouted at Harry's answer but then smiled as he thought of pranking twins. "Will I meet them?"

Harry thought about it and then looked over to Quatre who shrugged. "I'll take you to their joke shop. I'll have to ow—um, I'll send them a note about visiting."

"Awesome!"

"You do know that letting Duo meet two pranksters is a bad idea, right, Harry?" Quatre asked as he ignored Duo's happy humming and looked over to the older teen. "I don't know about your twins but Duo can get very serious about pranks and executing them."

"I'll make sure that all three of them are in my sight at all times," Harry said as he eyed Duo warily.

Quatre smiled and couldn't help but think that Harry's level-headedness was a good contrast to Duo's bouncy demeanor. It also helped that not once did Harry feel hostile towards his friends; there was nothing but caring coming from him.

'Maybe the Family Reconstruction Act was a good thing for Duo. He's never been so genuinely happy before. I hope nothing tries to keep these two siblings apart, well, not unless they want to deal with former Gundam pilots.'

Thank you to everyone who reviewed. I'm sure I replied to all of you, except for the people that weren't logged in. I hope you enjoyed this chapter. 3

Please feel free to suggest pranks of any kind, as long as they're not malicious, I don't want to kill the Dursleys… yet.
