Please bear with me as I tell you the story of the twins Patricia and Maria and their scheme to get their parents back together…

Patricia Snape was exposed to the muggle world growing up. The streets of London were very familiar to her, knowing the city's every corner, even though she lived in Spinner's End with her father, Severus Snape, the Potions' Master in St. Mungo's Hospital. The topic of magic always fascinated her. Her eyes grew wide at the thought of spells, potions, and wands. She always made it a point to learn more about magic; its history and beauty.

During dinner, a beautiful barn owl perched itself on their window. Patricia watched as her father retrieved the letter from the owl and shooed it away. The owl squawked at him indignantly before flying away.

"What is it, Father? Is it from Hogwarts? Because I already got my acceptance letter." She asked before eating a piece of meatloaf from her plate.

"A letter from the ministry..." He paused to continue reading. "It says that upcoming first-year students are demanded to attend a one-week seminar to prepare for Hogwarts."

"Father, please tell me I don't have to go. There will be an orientation when I get there anyway." Patricia pleaded, pushing her plate away.

"It says that this seminar is the orientation. Apparently, Dumbledore himself had signed this proposal, and now it's mandatory for all. Therefore, you are going. That is, of course, if you still want to attend Hogwarts." Severus gave his daughter a knowing glance. Patricia stood up and huffed loudly, "I'll go pack my trunk."

Severus watched as she went upstairs to her room. He waved his wand and whispered, "Scourgify." The plates, water glasses, and utensils were clean and neatly stored inside the cabinets. He looked at the letter in his other hand and sat down in front of the dining table once more. Behind the letter from the Ministry was another letter. The envelope was all too familiar.

To: Severus Snape

From: Albus Dumbledore

Patricia found herself hopping off the Knight Bus, standing in front of the dingy building that concealed the Leaky Cauldron.

"Now, you take care of yourself, okay? Your father will murder me if something bad happens to you," said Stan Shunpike, handing the girl her sleek black trunk with "Patricia Snape" engraved on the top.

"I will. Thanks, Stan." Patricia called out and watched as the Knight Bus dashed to pick up some other witch or wizard. She sighed before pulling on her trunk to head inside the famous wizarding pub. Tom the Landlord was in his usual front desk talking with a scrawny-looking wizard with a wooden leg.

"I'm Patricia Snape, and I'm here for the seminar." She said after dragging her trunk to the front desk. The man with the wooden leg was kind enough to give way for her to be recognized.

"Ah, yes. Your father informed me of your arrival. Although, I expected you later than sooner. Here's a key for you, please give your roommate the other key." Tom the Landlord smiled at her, handing her the keys.

"My roommate? I wasn't aware I had a roommate." She said in disbelief. Her father didn't mention anything about sharing a room with another person. "There goes my privacy..." She sighed quietly.

"Let me get your trunk for you, Dear." Tom lifted his wand, whispering "Wingardium Leviosa." Her trunk levitated from the ground. Patricia's eyes grew wide in excitement.

"Don't tell Professor Flitwick that I showed you that spell, he always loved showing it to his first years." Tom chuckled. Patricia nodded, still in awe of the floating trunk.

"Who's Professor Flitwick?" She asked.

"A great man willing to teach you great things..." He answered. The man with the wooden leg scoffed at the Landlord's answer.

"Stop trying to make yerself fancy, aye?" He had commented before he redirected his attention to Patricia. "Listen, kid, he's yer Pr'fessor in Hogwarts. All Pr'fessors in Hogwarts 're great!"

Patricia frowned. It was sad that her father had quit teaching at Hogwarts, but on the bright side, she would excel in Potions without people crying 'bias.' She murmured a quick 'thank you' before she climbed the wooden staircase, her trunk now guiding her to her new room. Her room was the 2nd one to the left; branding a golden number 4, her name, and the name of her new roommate:

Maria McGonagall.
