Chapter 1:

They had just settled in to have dinner and the Black House, also know as the Order of the Phoenix Headquarters. Harry was taking in everything he found out. Voldermort was building up an army; he was getting powerful to kill him. Even if Molly wasn't sure about Harry knowing, Sirius couldn't keep hiding it from him. There was such a silence, Molly quickly changed subject.

"So…Hermione, dear… has your cousin answered?"-She asked Hermione who got the fork back to the plate.

"Um…she did."-Hermione just placed both hands on her lap and looked down.

"You have a cousin?"-Ron asked with mouth full. Hermione just gave him a glare.

"Well…kind off…she's the…foster daughter of my parents' best friends."

"You didn't mentioned she was adopted"-Molly said, pitching food into her fork

"Yeah, she is."

"So, what's the story?"-Harry finally spoke, seeing Hermione nervous.

"Well…she's 2 years older. She's a bit of a…wreck."

"Don't say that"-Molly told her

"She is. Al though I love her, she has a bit of an attitude"

"Noticeable you're not actually related"-Ron commented and got another glare of Hermione.

"Anyways…her story is she actually ran away from her real parents around 10. She went to an orphanage. Then my parent's friends adopted her, knowing who she was. She actually was in Hogwarts."

"How come we've never seen or know about her before?"-Harry asked

"That's the thing…she ran away from Hogwarts too. My parents and hers begged her to stay for my first year, so she could help me with anything."

"And she never did?"-Ron asked, already seeing this cousin of hers as a bad person

"No, she did. A few times when I was at the library alone, she was around. I know she was watching me. She even made Malfoy and his two bloody idiots run. That's why I really like her. But around my second year, she stuck around again. She was even beside me most of the time when I was petrified.-"

"Why didn't we see her?"-Ron interrupted her

"She said it was better if she didn't hang out with me most of the time. Because of her reputation. She knew that if she hung out with me, people would treat me worse. She has a bad record with a few students at Hogwarts. Especially with the Slytherins. She always pranked them, Malfoy the most for making fun of me. You wouldn't believe this; the first time he called me…well you know…she actually turned him into a pig and got him into the forbidden forest."

"Bloody hell! No way!"-Ron exclaimed and Harry laughed.

"Wicked."-The two ginger twins spoke.

"That wasn't really nice"-Molly acted all parenting like.

"Mum, its Draco"-Ron explained

"I don't care. What happened to the boy?"

"Well a pack of werewolves ran behind him, but she saved him. It was mostly to scare him. She wouldn't really kill anyone. But she erased his memory of that night so he wouldn't speak."

"What house was she anyways?"-Harry asked cleaning his lips with a napkin

"Surprisingly she was in Gryffindor."

"How come we never heard of her?"-George asked, getting an interest in the conversation.

"Maybe you did. Around my third year was when she left. She left a month after school started."-Hermione took a drink and sighed.-"no one has seen her since"

"It's really dangerous for a witch with out training to be wondering around on her own."-Lupin added to the conversation. Sirius, Tonks, Moody and him have been listening to the conversation al along.

"I know. During this summer I tried to contact her, I finally did. She has been traveling the world. I told her to come here-"

"Come here?"-Moody shouted, scaring everyone.-"This is not a motel for some childish runaway!"

"Mad-eye…"-Sirius told him, calmly.-"This might be a good idea. A girl like that could easily fall into Voldermort's side. It's best if we have her on ours."

"That's why I've been trying to contact her."-Hermione spoke and the eyes were on her again.- "After she said she would come, I send a letter to Hogwarts, asking if she could come back, at least for her last year and explained the situation. Luckily it was McGonagall, she said to bring her when Hogwarts starts to see how she is. If she has changed, they will take her back. I want to talk to her before school starts, so I can convince her."

"Do you think she will accept?"-Harry asked, hoping the girl did. He knew it'd be a big help. But Hermione sighed.

"I…I doubt, but it's worth the shot. Molly and I are going tomorrow to Diagon Alley. She said she would see us there. Then we'll bring her here and see"

"Well, I really hope what you're doing."-Moody said walking away.

Hermione just looked down with jaw open, like trying to speak, but couldn't. She didn't know what to say. Molly just petted her shoulder. Everybody went back to eat. The next day, Harry and Arthur got up for Harry's hearing and Molly and Hermione got up to go to Diagon Alley.

"Good luck today, Harry."-Hermione said to Harry

"Thanks, good luck to you too"-He answered

Suddenly, in the blink of an eye, George and Fred appeared.

"Hermione!"-Both shouted scaring their patents, Harry and Hermione.

"Fred! George!"-Molly yelled

"We were thinking-" –Fred started.

"Since your cousin it's a pranker-" –George continued

"We should welcome her-"

"As one-"

"No!"-Hermione stopped them before they went on.-"I want everything to go well. If you do something to her, she might not go back to Hogwarts."

"Awww!"-Both said

"Boys! No pranking her cousin."-Arthur said, pointing at both.

"Alright…"-Both said, looking sad.

The four of them left, leaving the twins alone to go back to their room. Molly and Hermione got to Diagon, and waited for her cousin to show up. They waited for an hour in front of Gringotts and later went to walk around, Hermione wanted to believe her cousin just got lost and she was wondering around.

"Hermione, it's getting later dear, maybe try to contact her again."-Said Molly, putting a hand on her back.

"I just fooled myself. She completely forgot about me."

"Don't say that. Maybe something came up."-Molly lied to comfort her. "Let's go back to the house, maybe she sent a letter."

This time Molly didn't lie, she just hoped. Hermione nodded and they left. Everyone else was at the house, including Harry and Arthur who were talking to Sirius and Lupin on how the hearing went. Everybody else was listening. Suddenly a "Boom!" came from the hall, followed by a yell.

"Fred and George Weasley!"-Yelled Molly

Fred and George just looked at each other. The rest went to the hall to greet Hermione and Molly, filled with confetti over them. Molly wasn't too happy, neither was Hermione, but the confetti was the least of her worries. Fred and George appeared closer to them.
"It's not really a prank"-Both said at the same time

Molly gave them a glare and raised her finger, but before speaking, Ron interrupted since he saw Hermione all bumped.

"Where's your cousin?"

Molly let her arm fall and looked back at Hermione. Everyone did, she was looking down.

"She didn't show."

There was a silence until Ron spoke.

"I'm going to kill that bloody girl."-He said putting his hand into a fist.

"That's sweet, but she would probably beat you up."

Harry, George and Fred laughed a bit at Ron, who turned pink.

"I'm sorry…"-Hermione said. –"I just…I'm going to take a shower."

Hermione went up the stairs and there was a silence.

"Have you actually seen the girl, Molly?"-Arthur asked

"No. I just know what Hermione told all of you. I didn't even know she was adopted. But I feel that girl will come around. If she was there for Hermione before, why not now when things are worse? She knows Harry it's one of her best friends, she will come into her senses."

"I think so too."-Said Harry.

"Let's all have a good lunch. Tomorrow it's a big day. You hall need to get your school supplies. Maybe we'll bump to her there."-Sirius suggested and everybody followed.

After Hermione took her shower, she went downstairs. Everybody wanted to ask if she was alright, but they knew it was better to leave it for later. Fred and George noticed it was too quiet so Fred lighted up a fall of light and started to throw it at George, who catch it in his hand.

"Oi, Ron!"-He yelled at Ron as a heads up.

He threw it at Ron who hit it with his hand tours Harry, who hit it to Sirius. They kept hitting it around and having a good time until they heard a BOOM coming out of the hall way and the lights of it turned out. The ball of light disappeared and every one looked at the hall. Sirius and Lupin got up and went to the hall. They saw a shadow with a wand and their wands were out.

"Expelliarmus!"-Lupin shouted, but the spell had no effect since the shadow did the protego spell.

"Stupefy!"-the shadow shouted, but Lupin and Sirius hid. The others had their wands out, but Hermione pushed them.

"Stop!"-She yelled and pushed Sirius and Lupin.

"Hermione!"-Harry and Ron yelled and went after her, but she was already half way into the hall way. They stopped at the entrance. Hermione got closer to the shadow who was still with the wand out, prepared to fight.

"Lumus."- Said the shadow and a light appeared at the end of her wand.

The girl got it close to Hermione's face and let out a little laugh. The girl turned the hall way lights on. She was a bit taller than Hermione. Had blue-black straight hair, with bangs that covered half of her dark brown eyes, she was pale and she was wearing black pants, boots with out heels that hid the end of the pants in them, a purple top and a black jeans jacket. She was carrying an old looking messenger bag. The girl smirked.

"Kat?..."-Hermione asked, insecure. –"Katherine?"-She asked again with the girl's full name.

"I prefer Kat…cousin"-The girl smirked again.

Hermione let out a little smile and hugged her. Kat hesitated on hugging her back, it has been so long since she felt some arms around her, but gave in.
