As the plane landed at the London airport, Cassidy Lily Potter felt nervous. She knew that she had to do this. She just didn't want to. Her whole life, she had been safe and secure and loved. Now, she was forced to leave her home to live with people she didn't even know.

They betrayal of her Uncle Michael and his family hurt her deep down, even though she didn't show it. They loved her, she knew that, but sending her away to a new home was not normal for them.

As Cassidy was leaving the terminal, she caught sight of a tall, thin man with tawny colored hair, and golden eyes. He was holding up a sign with the name 'CASSIDY LILY POTTER' in capital letters on it.

Sighing, Cassidy made her way over towards the man. She held out her hand as she introduced herself.

"Hello. I'm Cassidy Lily Potter. You are, sir?"

"I'm Remus Lupin, Miss Potter. Let's gather your bags and be on our way, shall we?"

Cassidy nodded as she lead the way to the baggage retrieval, trying to recall where she had heard his name before.

Once they were outside, a tall, black man stood next to a Rolls Royce, looking around, as if checking for danger. Getting into the car, Cassidy noticed a woman with short, funky magenta hair in the driver's seat, and a man who greatly looked as if he had other things to do that were far more important.

As the car drove off, Cassidy broke the silence.

"Does someone want to tell me what's going on? Uncle Michael said very little about this whole thing. By the way, my name is Cassidy Lily Potter. What are your names?"

The black man answered first.

"I'm Kingsley Shacklebolt."

"I'm Nymphadora Tonks, but please just call me Tonks or Dora."

The other man wasn't pleasant when he answered, even going as far as to turn around and glare at Cassidy.

"My name is Severus Snape. I am the Potions Master at Hogwarts. Lupin is your guardian, and the other two are Aurors."

A admiring sparkle appeared in Cassidy's eyes.

"You teach Potions? How wonderful. I simple adore Potions. It's my favorite class. I even got an Outstanding on my Potions O.W.L. In fact, I got eight Oustandings and four Exceeds Expectations."

Remus looked impressed.

"What classes did you get 'Exceeds Expectations' in?"

"History of Magic, Divination, Care of Magical Creatures, and Muggle Studies."

Kingsley shared a look with Remus.

"What about your eight Oustandings?"

"Potions, Transfiguration, Charms, Herbology, Astronomy, Defense Against the Dark Arts, Arithmancy, and Ancient Runes."

Silence took over the inside of the car while the four adults thought about Cassidy's scores. Cassidy, on the other hand, put her ear buds and turned on her iPod, jamming out to one of her favorite songs: Girl All The Bad Guys Wants by Bowling For Soup. Remus, being a werewolf, heard the music before Cassidy turned the volume up all the way, which allowed the other occupants of the car to listen to the music, as well.

After another twenty minutes, the car pulled up next to a park across from several townhouses. Before Cassidy got out of the vehicle, Remus showed her a sheet a paper and told her to memorize the address, and to think of it once she got out of the car.

After thinking for about thirty seconds, Cassidy opened her eyes and saw a regal-looking house that had a gothic theme to it. Following Remus' lead, Cassidy entered the house, with Snape, Tonks, and Shacklebolt behind her. The first thing she saw was darkness, until her eyes adjusted, then she noticed a handsome man with long, wavy black hair standing on the staircase in front of the group.

Under the man's stare, Cassidy became extremely nervous. As he stepped down one stair at a time, Cassidy took a step back towards the door, only managing a few steps before she hit something soft, yet solid. Turning, she noticed that she had backed into Snape. Looking over shoulder, she saw the man still walking towards her, and she began panicking, causing her to hide behind Snape, grasping the back of his robes, burying her face into his back.

That motion caused the mysterious man to stop where he stood and look at his old friend, Remus, with a puzzled look on his face.

Remus shrugged at his friend before turning to walk over by Cassidy.

"Cassidy, it's okay. This is Sirius Black, the owner of this house. Both Sirius and I were friends of your parents when we were in school. Come along, let's get you something to eat and drink."

When Cassidy shook her head and didn't budge, Remus looked at Snape for help. The poor Potions professor looked just as uncomfortable as Sirius with the situation. However, when Snape took a step forward, Cassidy moved right with him, not letting him go, or seeing where they were going.

In the dining room, the Weasley family, along with Hermione Granger, Harry Potter, and the rest of the Order, were sitting at the long dining table, waiting for the others to join them. Sirius and Tonks entered the room first, followed by Remus and Kingsley, with poor Snape bringing up the rear, Cassidy still clutching to him as though her life depended on it.

When they saw Snape's predicament, Fred, George, and Ron Weasley, and Harry burst out laughing, with Dumbledore chuckling lightly in amusement.

Cassidy kept her hold on Snape, but moved her face to look at everyone in the room. Her face took on a look of shock when she saw Harry, just like Harry was taken by surprise when he looked at her.

"You look like my father."

"Yeah, well, you look like my mother."

Remus stepped up next to Cassidy while Sirius stood next to Harry, and they said at the same time: "You're twins."
