Not-So-Fake Marriage

Two little boys raced through the hallways in Potter Manor. Their exuberant shrieks of laughter echoed down the hallways, filling the air with happiness.

At first glance, they looked identical. Both of them had messy, short black hair, and they were the same height. Their bone structure was the same, and their hands were dirty from playing outside. However, if someone took the time to look past the round black glasses, they'd find the difference between them.

James Potter, the elder of the two, had deep hazel eyes that often showed more brown than green.

Harry Potter, the younger twin, had mossy green eyes and he was often told how they looked exactly like his mother's. No matter how many times people told him that, he always got a wide grin on his face. After all, his mother was the most wonderful woman alive, and he wanted to be just like her.

They skidded around the corner, barely avoiding crashing into a pedestal that held an expensive vase. "Phew!" James exclaimed, sighing in relief.

"Mum would've walloped us good," Harry whispered with wide eyes.

They could play inside, they could even run inside, but that was only allowed because they'd promised not to break anything. They both knew that if they ever broke their promise they'd only be allowed to play outside, and that wasn't always fun.

The manor was huge! And they could go exploring.

Today they were playing explorer tag, the pirate version.

James reached down and pulled a long stick from its precarious place in his trouser loops, and pointed it at the vase. "Ye can't 'ave my Harry!" he said, a serious look on his face.

Harry giggled childishly and then hurried over to hide behind his brother. "Oh! Captain James, save me!" he wailed theatrically.

James grinned widely and then lifted the stick higher, poking the pedestal carefully. He made sure he didn't prod it too hard, because he really didn't want it to break. "He's mine, and I be keepin' 'im." James tried to growl fiercely, but it came across sounding like a kitten's purr.

"My hero!" Harry said, raising one hand to press it against his forehead.

James giggled, dropped the stick, and then grabbed Harry's hand, tugging him down the hallway and towards their parents' room. He pushed open the door without knocking and walked over to his mother's jewelry box; it was made of black walnut, had many doors and drawers on it. Constellations were engraved on the sides.

"What're you looking for?" Harry asked curiously when his brother pulled open one drawer after another.

"I haven't found it yet," James said with a pout.

"We're not s'posed to be in here," Harry whispered loudly. He kept glancing back towards the door, afraid that his mum would appear and catch them. He really didn't want her to take away his new broom again! He'd just gotten it back!

"Got it!" James said excitedly as he pulled what he'd been looking for from the second to last drawer. He held the item up proudly; it was a tiara, silver, with blue pearls and diamonds all along the front. It had small-edged combs at the back to keep it in place. James leaned forward, reached up, and put it in his brother's hair.

Harry grinned widely, momentarily forgetting his fear of being caught, and spun in a circle. "How do I look?" he asked, batting his lashes.

"Pretty," James said decisively.

James reached forward and wrapped his hand around Harry's before tugging his twin behind him once again. They left their parents' bedroom and headed down the hallway. James's smile turned into a frown as they kept passing rooms without seeing anyone.

"Mum!" he yelled.

"Yes dear?" she called back.

"Where are you?" he asked impatiently, voice echoing down the hallway.

"In the drawing room, James," she answered; her voice was soft and elegant, and it brought a smile to her sons' faces.

"Stay there, Harry and I need you for something!" he ordered as he marched forward, continuing to pull Harry along with him.

Her musical laughter floated down the hallway. "I'll be here, James," she said reassuringly.

"Good," James said.

"James, we're gonna get in trouble," Harry whispered loudly.

"No, we won't," James replied confidently.

"But we were in Mum and Dad's room without permission," Harry hissed. "And I'm wearin' Mum's girl crown!"

"But you have to wear it, so she won't get mad," James said, trying to imitate their father's mature tone of voice.

Harry tilted his head to the side, almost dislodging the expensive tiara, but it clung stubbornly to his messy black hair. "Why do I gotta wear it?" he asked.

"Because we're getting married, Harry," James said determinedly, his eyebrows slightly furrowed.

Harry blinked at him and almost tripped as he stopped walking, but his brother dragged him onward. "But we're boys," Harry said. "Boys marry girls."

"Nu uh," James said as he shook his head. "Dad said that people get married because they love each other." He glanced back over his shoulder at Harry and smiled widely. "And I love you!"

Harry's cheeks colored slightly, but the grin on his face was beautiful to see, full of innocence and joy. "I love you too," he confessed.

"That's why we're gonna get married!" James said proudly. "You'll look pretty, and I'll take care of you."

"Okay," Harry whispered shyly as he turned his gaze down to the shiny wood floor that lined that hallway. The house-elves polished it every day and he liked looking at it because he could see his face, just like in a mirror.

They finally reached the drawing room, which had been at the very end of the long hallway, and they walked in together. James moved his hand, entangling their fingers, and led the way over to their mother.

"James," Dorea Potter began as she brushed a lock of dark blonde hair behind her ear, "why is your brother wearing my tiara?"

Her lips were twitching, and Harry wasn't sure if that was a good or bad thing. Was she going to yell at them? They had broken the rules, after all.

"Because he's my wife," James replied, letting go of Harry's fingers to wrap an arm around him.

Dorea laughed softly and her eyes sparkled merrily down at her sons. "He is, is he?"

"Well, he will be," James answered. "But you gotta marry us first." He gazed up at her, a determined and fierce expression on his face.

"Oh?" She cocked a perfectly sculpted eyebrow and gazed down at her youngest fondly. "Do you want to marry your brother, Harry?" she asked him. The barest hint of amusement could be heard in her voice.

"Yes Mum, I love James!" Harry said earnestly, a wide smile on his face.

"Please Mum, please marry us!" James begged.

"Please!" Harry pleaded as he batted his lashes prettily.

Dorea chuckled loudly and then nodded her agreement. "Very well, if you're sure boys, this is a lifetime commitment."

"We're sure," they chorused.

Lady Potter picked up her wand, from where it'd been lying on the blue chaise lounge beside her, and pointed it at them solemnly. "Harry Potter, do you promise to love and protect your brother all your life?" she asked, barely keeping her lips from twitching.

"Uh huh," Harry said.

James poked him in the shoulder, hard. "You gotta say 'I do', Harry," he whispered.

"Oh!" Harry blushed, watching his mother's lips twitch again. "I do!" Harry said, meaning it. All he wanted was to stay with James forever, and married people had to live together until they died. He knew that much at least.

Dorea smiled at them and then turned to look at her oldest son. "James Potter, do you promise to love and protect your brother all your life?" she asked him slowly, amused by his impatient shifting.

"I do!" he answered instantly.

"I now pronounce you Mr. and Mr. Potter," she said, unable to hold in a chuckle as they smiled widely.

"Thanks Mum!" they said in unison.

James turned to face his brother and wrapped both arms around him in a close hug. "This is where we kiss!" he said happily. He leaned forward and pecked Harry on the lips.

The moment their lips touched, a brilliant flash of white magic encased the twins and Dorea stared at them with horror and fascination. "Oh dear . . . that's unexpected."

They'd really meant their vows; it hadn't been a game to them.

She'd just married her sons to one another. How was she going to tell her husband?
