"Well, that went over like a lead balloon." McGonagall said hoarsely after witnessing what had just happened. "She doesn't believe it."

"Oh, she knows it's true. She just doesn't want to believe it." Replied Dumbledore quietly. He was now standing in front of his desk staring out the door where Kacey had just disappeared.

"What's going to happen now?" asked Sirius, who had just returned to his human self. He put a comforting hand on Harry's shoulder.

"She'll be back." Said Dumbledore as he turned to face Sirius, then head back towards his desk. "So what do you think, Harry?" Harry looked goggle eyed at Dumbledore. He couldn't possibly expect Harry to comprehend this and be taking it in very well. Harry asked the only thing he could think of.

"How?" Harry asked barely above a whisper. "how could this happen?"

"Harry, I know this is hard to understand and that you may not believe it's true, but it is." Dumbledore said quietly and comfortingly. Harry didn't know why, but he believed it. He knew deep down that it was true. "What happened that night will never be completely known. You were only a baby. What you see aren't memories, but flashbacks. Some of which you don't understand. Voldemort and Madison, however, were both perfectly capable of remember something like that. Especially Madison. She was only three years old." Harry glanced over at Sirius who looked lost in thought.

"Harry, in your flashbacks, did you see or hear anything unusual?" Sirius asked. Harry thought about it and tried to remember what he had heard when he was around the Dementors. "Anything at all"

"Now that I think about it, I do think I remember hearing a baby crying." Harry said. "But I always thought that was just me."

"Harry, that wasn't you. When the Ministry got there, you were fine and content. Totally unaware of what had happened." Sirius said.

"Wait a minute." Said Harry, suddenly looking furiously at Sirius. "You knew?" Sirius looked thrown off for a second and then sensed danger and made quick to explain.

"Yes, Harry, I knew. But please try to understand that I couldn't -" Sirius started.

"How could you do that to me, Sirius?" Harry was now standing up and facing his godfather with his fists clenched. "You were the closest thing I had to a family and when there is someone walking around with the title of my sister, you don't even tell me??"

"Harry, I..." Sirius tried again.

"Harry, in order for this to work, you must calm down." Ordered Dumbledore firmly. "Now I think you ought to know that Madison does know it deep down. She has been coming to me for years to talk to me about her strange nightmares and her visions. She hears and sees the same things you do. But you have to understand that this is going to be a lot harder on her than it is for you. She's been living a lie for fifteen years. She believed the Harper's were her parents and was told she was born in the states as Kacey Harper. She was brainwashed. Give her some time to think about it and she'll come around. Trust me."

Harry just stood there in stunned silence. He didn't know what to think. A girl he was just introduced to only about a week ago is now his long lost sister. "Who all knows?" He finally managed to ask.

"The Ministry, Sirius, Professor McGonagall, Madison, you and myself." Dumbledore replied. "The rest of the staff will be informed tonight at dinner. The rest of the students are to find out whenever Madison decides what to do. She has the choice of coming into your life and being the sister you never had, or she can stay with the people who have lied to her for so many years. Hopefully, I'm right in what I think she'll do. If she does decided to come into your life, are you prepared to accept her, Harry?" Harry nodded. "Good, because she is going to need someone to help her through this and you might just be that person." Dumbledore gave Harry a little smile. "Now I'm going to let you just go ahead and go back to your common room or your dormitory. I understand that you will want to tell Mr. Weasley and Ms. Granger as they are your best friends, but please, keep it limited to them." Harry nodded again.

He started to head out the door when Sirius put his hand on his shoulder, causing Harry to turn towards him.

"I know you would like to go with him, Sirius, but I need you to stay. We need to discuss your assignment." Dumbledore said softly from behind Sirius. Sirius sadly looked at his godson before closing his eyes painfully. He then did something he had never done before: he pulled Harry into an enormous, long bear hug. Harry felt wonderful. It was the first time anyone other than Hermione had ever hugged him because they really cared for him. "I'll be seeing you and Madison soon." Sirius whispered to Harry. Harry then grinned and walked out the door.

Kacey wasn't at dinner that night. A lot of people noticed it too. Apparently, she was always present when she had a big duty such as Head Girl. Rumors were flying all over the place that she and Oliver had finally eloped. After their appearance at the trains station, the entire school soon knew about them.

When Harry told Ron and Hermione, they replied with, "Oh my gosh!" and "I can't believe it!" and of course, "But...Madison Potter died though, didn't she?". They also ended up showering Harry with more friendly affection than what was really necessary. They also decided to continue to call her Kacey unless she changed it back, after all, it was her legal name. Harry noticed a look on disbelief on most of the teachers faces which lead him to believe that Dumbledore had told them.

Snape was sitting at the end of the table. He didn't look shocked, but he looked...angry ...and betrayed. 'God only knows what's going through his mind,' thought Harry. He looked around at his fellow classmates and thought to himself, 'I wonder if they are just as oblivious as I was...'. He didn't even know he had had a sister, let alone know she was supposedly dead. Dinner wasn't too good that night as he didn't have any appetite at all. He gave up about half way through his mashed potatoes when he gave up.

"Wer' ya goin?" snorted Ron with an enormous hunk of beef rolling around in his mouth. Hermione looked up questioningly too.

"I'm calling it a night. You'll be up to the room soon?" Harry asked. Ron nodded when he saw the disgusted look on Hermione's face.

"I hope you feel better in the morning, Harry." Said Hermione as she jumped to her feet and wrapped Harry in her arms. "She'll come around...and so will you."

As Harry made his way up to the Gryffindor tower, he was thinking about what Hermione had said. 'She'll come around...and so will you." Her words made sense.

"Fruity bat." Harry mumbled to the portrait. As he climbed him, he looked around the common room for possibly a sight of Kacey. But she was no where to be seen. He should have figured. He slowly walked over to the staircase leading to the boys dormitory, then he glanced back over his shoulder at the girls staircase. 'What the hell.' He thought to himself and turned around to go up the other staircase.

Maybe if he could see her and talk to her a bit about it, they'd feel more comfortable about it. A little visit can't hurt...or can it? When Harry got to her door, he stopped dead in his tracks. She was screaming. He put his ear to the door to hear better.

"YOU KNEW!" She bellowed. "YOU KNEW THE ENTIRE TIME! HOW COULD YOU DO THIS TO ME?! I TRUSTED YOU WITH MY LIFE AND YOU COULDN'T EVEN TELL ME THE TRUTH??" 'This sounds familiar' Harry thought. Then he heard something hit the wall and shatter.

"I couldn't tell you!" came a boy's voice. "Dumbledore made me promise to never tell you! And watch where you're throwing that!!"

"I CAN'T BELIEVE YOU!" She roared again. She threw something again, presumably glass as the was it smashed into pieces.

"Cedric knew too."

"OH MY GOD!" she thundered. "Does EVERYONE know about my life except ME?" This time, something hard hit the wall and thumped on the floor.

"I told you I was sorry, what more do you want from me?" said the boys voice. "I came her to comfort you and got my arse bitched off."

"Oh, God. I am so sorry, Oliver." She apologized through her tears. "I just can't believe that no one told me. I've been living like this for so long."

"It's alright. So what are you going to do?" Wood asked. There was a long pause after that question.

"Oliver, you and I both know that I can't stay with the Harpers." Kacey finally said quietly. "I've been living a lie for fourteen years. And it's all because of them that I was ripped away from my only living family member. I just can't look at them the same anymore."

"What about Harry?"

"Well, you remember those dreams I had?" She asked. "Well, I think Harry was the one in them. I know everything Dumbledore said was true. What I decided to do was to change my name back to the name I was born with and now I want to meet my aunt and uncle and move in with them this summer. I just want to be the sister Harry never had. I'm going to Dumbledore tomorrow morning to tell him." Then there was a pause. "And I'll tell Harry too."
