Lyn stretched slowly as she opened her eyes—then she froze. Where was she? The events of the previous day came rushing back. 'Well, apparently it wasn't a dream,' she thought. Suddenly, panic hit her full force. 'WHAT ON EARTH AM I DOING HERE? WHAT AM I GOING TO DO?'

Lyn took a few deep breathes to calm herself down. So far, things were not going like she had expected. She had to teach Potions with Professor Snape, and she knew absolutely nothing about Potions. She was supposed to be working for the Order of the Phoenix but had no idea how to contact them. And worst of all, her first attempt to make a move on Draco had gone rather badly, if memory served:

Lyn touched Draco's arm again, this time a little more gently.

Draco looked at her for a moment. Then he got up and headed for the door. "Get some rest, Tyra," he said.

"But I'm feeling much better now. Why don't you sit back down for a while?"

"One, you're going to be my teacher, and I'm pretty sure that's not allowed."

"I'm not your teacher yet," Lyn purred seductively.

"Two, I'm DATING YOUR LITTLE SISTER! Do you really hate Pansy that much?" Draco said accusingly. Lyn looked at him blankly. "Get some rest, Tyra. I'll see you later." And he was gone.

It had definitely gone quite differently in her head when Lyn had been planning her story. 'I'm Pansy Parkinson's sister? What in the world! Well, at least I know my last name now,' she thought.

Lyn got up and went to the closet to choose something to wear. There she received another shock, this one a lot more welcome. The closet was full of sexy designer clothes, the kind her lamo parents would have had a heart attack just thinking about. Lyn pulled out a form-fitting red lace camisole and a black leather miniskirt. At first, she couldn't even bring herself to put them on; then she remembered she was curvy now, not fat. She finished off her outfit with a silver chain belt and knee high boots. 'I look fabulous,' she thought as she heard a knock on the door.

Lyn ran downstairs and opened the door to see none other than Professor Snape himself. 'Wow, he's not as attractive as I expected, but with a little shampoo and a smile…' Lyn thought to herself.

Professor Snape looked her up and down for a moment. "Change. Now."

Lyn's inner fat girl instantly came back to haunt her in the form of self-consciousness. She turned to go upstairs. But then, she made herself stop, tossed back her long golden curls, and said, "Hello to you, too. Won't you drop dead, I mean, come in?"

She turned and started to walk away when she heard him say, "Ridikulus." Suddenly, she was wearing a long, red, shapeless dress with garish pink feathers sewn all over it. There was even a long feather in her hair. She turned and gaped at Snape.

"What, you thought it only worked on Boggarts?" he smirked.

"Change it back!" she screeched.

"Change it yourself." He calmly walked past her and sat down on her couch.

'Oh yeah, I'm a witch,' she remembered. Then she closed her eyes and wished herself into jeans and a t-shirt, which was, of course, much more comfortable but not nearly as attractive. Then again, did she really want to be attractive aroundsuch an obnoxious git?

"Now if you're done being immature, we can get to work," said Snape, waving his wand to produce a teacher's planner. "Ms. Parkinson, I want you to know I have never accepted an intern before and I have no desire to do so now. I am only doing so because, one, I have been ordered to, and two, you scored a perfect on your NEWT, though I don't know how you managed it with the imbeciles you've had for teachers these last few years."

"Haven't you been my teacher?" Lyn asked.

Snape turned to her with a withering look. "I meant your Defense Against the Dark Arts teachers, not all your teachers."

Then Lyn remembered. This was Half Blood Prince. Snape didn't teach Potions this year. Suddenly, Lyn wished she had finished the book before this happened….
