Leta Lestrange sure was a funny girl. I mean, she came from a pure-blood family, and she decided to befriend Newt Scamander of all people. He was a Hufflepuff; she was a Slytherin. He honestly thought she liked him for who he was.

That was half of the truth.

In reality, she was falling in love with him. He was so beautifully different, that she just couldn't stray away.

But as a friend? No. He was easy to use, to manipulate. He always forgave her, no matter what. He always took the blame for her. He was nice like that. He deserved a nice friend in return. Something Leta could only pretend to be.

A couple of weeks ago, Sebastian Brawn had asked her out. He was a Gryffindor, and one of the more popular ones. He was one of Theseus's friends, and he was well liked. But she had refused him. All he did was ask for her answer repeatedly, hoping it would change.

It didn't. Soon, he gave up trying. But she just happened to overhear a joke about her, coming from him. It was only meant to be funny, not cruel, but she snapped.

That was the last straw. She became furious, and seeking revenge. And the Lestrange family would do anything to get revenge. She had the perfect plan in place. If anybody saw, they wouldn't think it was her. Sure, Brawn could plead all he wanted, but she would never get caught. They would all think it was Newt's. And he would willingly take the blame. Yes. And not one bit of her felt guilty. That was a trait of the Lestranges, and it was something she was brought up to fear.

…

In the Great Hall, Leta had gone from the Slytherin table, which was hers, over to the Gryffindor table. She felt a twinge in her stomach. It almost made her reconsider. Almost.

"Hey Seb! Can I talk to you alone for a minute?" She made sure to put on a sweet smile for him, just to make him feel special.

"S-sure! I… um… Ok!"

Perfect. She waited for him to get up, and then led them out of the hall. She kept on walking until she found the broomstick cupboard.

"What is it, Leta?"

"I wanted to talk about the question you kept asking me. I really don't like it. And I hate that joke you made about me. Ah- don't talk! I just wanted to say, I'm sorry. I know how it is to feel heartache after being rejected. But you're going to have to pay. Bye!"

She swept out of the door, swaying her hips on the way, whilst bearing a white smile. She slammed the door, then locked it non-verbally.

As she walked on, she swore that she heard muffled screams.

…

"Mr Scamander. You mean to say that the jarvey isn't yours, and yet it managed to find its way into the school?"

Newt was in tears. Who would want to set a creature on Sebastian Brawn, of all people? Certainly not him. Someone had framed him. He nodded frantically.

"I repeat, expelled!"

…

The story of how Newt had been expelled spread like the wind. Leta couldn't believe it. It made her upset. And she almost regretted it.

Almost.

And yet she couldn't help confessing to Professor Dumbledore, who taught Transfiguration. He was the only nice teacher in the school.

She sent an anonymous letter to him, explaining that it was her.

And now there was no guilt left in her. Almost.

…

Everyone was avoiding her. She couldn't tell why. Not until she read the article in The Daily Prophet.

It turned out that she had put her signature at the bottom of the letter.

And then she sat and wept.

She was completely regretted it now, and she was feeling completely guilty.

And she wasn't proud of herself, or her family name. For she had betrayed everybody. She must put it right. And she couldn't do that alone.

Was every hope of hers destroyed?

Almost.
