Prologue

"Just think of the good you could do," said Sirius. "You completing this task could possibly help save the wizarding world."

"I know, but I would simply be a traitor," I reasoned. I would have to go back home and reunite with my parents, which was the last thing I wanted to do. I had been staying at the Burrow since the summer after my first year of Hogwarts when I ran away. Ever since then, my mother had recruited my cousins, Daphne and Astoria, to try to get me to come back home. Not because they genuinely missed me or anything, but because the Dark Lord was expecting Draco and me to become Death Eaters once we are of age. If word got out that the Kassidys couldn't even raise their daughter to obey the dark lord, their reputation as Pureblood wizards would be ruined. They could not have that.

"Katrixie, it is all for the people who have risked or lost their lives to protect us all," said Remus. "To protect you,"

"I still don't know if I can do it," I answered. The last time I had seen my parents, they had beaten me for embarassing them at my twelfth birthday party. I didn't know whether they would be greatful or angry at my return.

To be honest, I just didn't want to leave my friends. I wouldn't be allowed to tell them anything about being a double agent because I would have to be as convincing as possible. Dumbledore was even having me move to the Slytherin House in order to help that cause.

"I suppose that accepting the task wouldn't be that bad..." I debated. I would be helping the Wizarding World...

"Fine. I accept," I said finally. Sirius and Remus let out sighs of relief. "But I won't join them until the end of this year. After the Triwizard Tournament is done. I can't leave them behind until then. Alright?"

"Alright," said Remus as he and Sirius exchanged a look. I looked down at my hands.

It was nearing the end of the summer before my fifth year. I was back at my parents' house. Draco and I were slowly being informed of the Death Eaters' plans, but not completely. They weren't all totally convinced that I was on their side. That meant that I had to up my game a bit.

Harry, Ron, and Hermione didn't take it so well at the end of term when I said I was returning home. Harry was convinced that I was shutting them out because of Cedric's death. I stopped talking to them altogether because it made it easier to follow through with the task.

It was almost the beginning of term, and it was time for a transformation. I had to make sure that my being on their side was believable, otherwise this wouldn't work. So I took down all of the pictures from my wall of me with the Gryffindors, and my wall became completely blank. I couldn't just store them in a box, so I burned them. In the living room fireplace, of course, so that my parents could see that I meant business. When I turned to them, they were speechless. After that, I decided that since I was moving to Slytherin House, I was going to have to get rid of my Gryffindor Pride stuff. So I went back to my room and collected all of it. I then proceeded to bring them down and burn them in the fireplace as well. This time, Father decided to grace me with his words.

"So I see you have purged your room of that Gryffindor rubbish," he said, somewhat proudly. Is he actually proud of me? I thought. I felt myself stand up straighter. I had never gotten approval from my father, let alone a proud remark.

"Yes, Father," I said, pleased that I was finally able to impress him. "I've even asked Dumbledore if he would move me to Slytherin House. Potter and those blood traitors have finally pushed me over the edge."

Now even though it was difficult for me to say those things about my friends, it was something that had to be done. If my parents didn't believe that I'd changed, then no one would.

"I'm glad to see that you've finally learned something useful at that school," chimed in my mother. "I was afraid that you were a waste of a child."

"Well no need to worry, Mother," I reassured her. "I've been enlightened."

"That's good to hear," She said, grinning smugly. "We are hosting a formal dinner tomorrow evening, and I have picked out a dress for you to wear. Your cousins, Daphne and Astoria, will be coming. So will the Malfoys."

And that was when they finally believed that I was on their side. After that, it was fairly easy to fit into my new character of Slytherin Princess. I started dating Draco soon after term began, and that lasted a while. I joined the Inquisitorial Squad, despite my desire to join the D.A., and I became a Slytherin Prefect. When we were getting interviewed about what we wanted to do with our lives, I said I wanted to be a teacher. And finally at the end of the year my parents participated in the Battle of the Department of Mysteries alongside Lucius Malfoy, Bellatrix LeStrange, and, of course, The Dark Lord. Lord Voldemort got away, but not before Bellatrix killed Sirius Black. After that, My father and Lucius were taken to Azkaban and my mother just barely avoided capture. Then, when people started arriving at the Ministry, they saw The Dark Lord standing in front of Harry and Dumbledore and The Minister lost his job. Umbridge last her Hogwarts job of High Inquisitor, and the case with my father and Lucius' arrest was a huge deal with the Daily Prophet. Lord Voldemort was angry with Lucius and Father because of how easily they got caught and how they let Harry get away. He was absolutely furious with his top families for letting Harry Potter and his 'team of Blood-traitors and Mudbloods' escape...

And they would be punished.
