Harry looked at his sister, confused beyond belief now. Cassidy had practically begged Snape to take her with him to his place. It was just way too hard for him to believe that they were twins.

As Remus showed Cassidy where her stuff had been taken, Harry and Snape glared at one another.

"What have you done to her?"

"I have done nothing, Potter. It's not my fault she feels better with me around."

"She's only known you for five hours. Give her time."

"She's coming with me because she wants to. I'm not forcing her, nor did I ask her to come with me."

After a few moments of silence, Remus entered the room with Cassidy in tow, with the latter keeping close to the wall. As soon as she laid her eyes on Snape, Cassidy visibly relaxed, making it seem like she had been uncomfortable being left alone with Remus.

After everyone said their good-byes, Snape placed his hand on Cassidy's shoulder and lead her out of the library and into the office, where they would be using the Floo Network to get to Snape's home on Spinner's End. Moments after Cassidy exited the fireplace, Snape began giving her a quick tour of his home before taking her upstairs, and showing her where she would be sleeping.

When Cassidy entered the room and shut the door, Snape turned and walked down the hall and to his bedroom, where he began getting ready for bed.

It was almost midnight when the storm started. As the rain pounded harshly on the window, seeming to want to break the glass, lightning lit up the sky, and the thunder made heavy-metal bands seem like school choirs. The second loud clash of thunder woke Cassidy from her deep sleep, causing her to start crying.

It wasn't as though she was afraid of the storm, the loud rumbling from the thunder just gave her a really big headache, like so many other things, like the sound of a train whistle right next to her, or gun shots, or fireworks. The loud noises gave her migraines that hurt enough to cause her to cry from the pain.

Scrambling out of her bed, Cassidy crept out into the hallway, and searched every room, looking for Snape. When she finally located his room, she tip-toed over to his bed, coming to a stop right beside him, staring at him, with her hand raised to shake his shoulder. Before she could touch him, however, Snape began speaking.

"You do know that it's rude to stare at people, right?"

Cassidy jumped a bit before stumbling to the floor. Snape used his wand to light a few candles in his room, so they could see each other.

"I'm sorry I woke you, but I have a terrible headache from the storm."

Snape raised one of his eye brows before reaching into his bedside table and retrieving a vial of headache relief potion. When he looked back at Cassidy, he noticed that her black satin bathrobe had opened a fair bit, showing her black lace negligee. Handing her the bottle, he turned away to look out the window. Sighing, he began speaking to her again.

"If the noise is bothering you, you can sleep in here for tonight. I'll put up a silencing charm to keep out the sound of the storm."

Cassidy quickly thanked him and downed half of the vial before handing it back to him. As she walked around to the other side of the bed, Snape couldn't help but notice the black, low-heel, fluffy slippers she was wearing, and how they made her legs seems longer and thinner.

Quickly shaking such thoughts from his head, Snape reached over and pulled the blankets back so Cassidy could crawl in beside him. Once she was settled, Snape used his wand to blow out the candles before settling back into bed, his back to her. He figured that if he didn't see her there, then his mind wouldn't wander.

That plan changed, however, when only a half hour later, Cassidy turned over and cuddled into his backside, her arm draped over him, and poor Snape hadn't been asleep yet. Just when he thought that things couldn't get any worse, they did.

Cassidy's arm slipped farther down than Snape was comfortable with, and within seconds, Snape's lustful side came to the forefront of his mind. When Cassidy began kissing the back of Snape's neck lightly, he knew she hadn't been asleep since before she came to his room. To make matters worse, Cassidy whispered the words Snape didn't want to hear: "Severus, take me."
