Fire And Ice - Yin and Yang (Harry Potter fanfiction)

Two stowaways

Periwinkle and Azalea Potter grew up in an ordinary house in an ordinary neighborhood. The Dursleys were as ordinary as a family could be. But they took precautions.
Should anybody belonging to that magical lot want to ask about the Potter twins, the Dursleys would simply deny that they lived here. That would be easy enough. After all, there was not a single photograph of the girls in the house, not a single pair of shoes by the doorway belonging to them, nor even a piece of their clothing laying around.

Azalea and Periwinkle were raised in a cupboard and all of their belongings had to remain inside. Anything that laid around in the house, Aunt Petunia would throw out. Periwinkle had learned that the hard way when she had found a beautiful blue hair clip with a sparkling butterfly on the sidewalk. She accidentally left it on the kitchen table and found out the next morning, that Aunt Petunia had thrown it into the garbage can. When Periwinkle ran outside to save her butterfly, she saw the garbage truck loading it away.

There was a fixed way of how the day was spent. Ever since Azalea and Periwinkle had turned four, Aunt Petunia left the house during the day to play cards with her gossip circle. Dudley was dropped off at a kindergarden and Uncle Vernon went to work. The twins were left with Mrs. Figgs, who always fed them with disgusting pink stew at lunch and then fell asleep at around two.

Her nap time usually lasted a few hours, which meant for the twins: freedom.

The many cats in the house had become boring for them after seeing them for so many times. But Mrs. Figgs had a television and she was as deaf as a doornail, so Azalea and Periwinkle had the best time of their lives when they could turn on the TV and watch a cartoon.

Only one day, things didn't quite go as planned.

At eight o'clock in the morning on September 1st, Aunt Petunia had an emergency meeting with Lucinda and Rosalie because of a party they had to plan, meaning she dropped off Periwinkle and Azalea at Mrs. Figgs and rushed away in her car.

Mrs. Figg's on the other hand, had an errand to run in London. Because she owed Aunt Petunia a favor, she had no choice but to take the twins with her.
Her errand was to buy a second-hand fur coat from a stuffy store that was crammed from one side to the other with old clothes that smelled of mothballs.
The moment the twins entered the store at ten after ten, they knew they were doomed.

And precisely after two minutes of watching Mrs. Figgs try on one coat after the next, the girls grew bored. That was understandable, since they were only four-year olds and had yet to learn the wonders of trying on clothes.

Boredom led to restlessness and soon Periwinkle found herself staring out the window at the building on the other side. She couldn't read the sign, but it looked quite pretty. There were many steam trains hissing and spitting out fumes before leaving the building. All were in a shiny black and looked extremely fascinating in Periwinkle's eyes.

She nudged her sister and pointed at the building.
"Let's look", she whispered.

Azalea's eyes grew wide and she nodded.

Mrs. Figgs didn't notice them creep out of the store. Nor did she notice the quiet jingle of the bells when the door fell shut behind them.

Moving as fast as their little legs could carry them, the twins hurried across the street. They had never learned how to cross one properly, but watching Aunt Petunia had taught them well. After all, she was the perfection of ordinary, meaning that if anyone had questions about crossing a street, Aunt Petunia would know the answers.

Their baggy clothes made it hard for them to move (since Dudley was four times their size and they were wearing his old clothes), but they succeeded in entering the building. The grand sparkling windows, the hissing trains, the busy people and the yelling conductors: it was a lot to take in.
