Disclaimer: I don't own it, just like it! This chapter introduces a new character and begins to work out some issues between all of them. It will get more exciting.

Mark walked down the hallway of the hospital looking irritated to be talking to the 15 year old girl who was following him. She felt uncomfortable in this unfamiliar place and lonely when she couldn't get her father to listen to her.

"Dad, my throat hurts and I just don't feel good."

"Kaitlyn, stop complaining. You're fine. You just want attention."

"Dad."

"You always want attention." He didn't realize that he walked right into Addison and her interns when he turned the corner. She overheard everything. She was annoyed with how he was treating his daughter.

"Mark, children need the attention of their parents. It would take you less time to look at her than to argue with her. Come on." She pulled Kaitlyn into an exam room. Mark followed. Alex stood at the door. Addison pulled a thermometer out of a cabinet. "You have a lot to learn so watch carefully." Addison began examining Kaitlyn. "First thing you should have done was take her temperature. And, what do you know? She has a fever." She was angry with Mark but spoke in a more caring tone to Kaitlyn. "I know I'm not your favorite person right now, but I'm trying to help you."

"I know." She giggled. "Besides I like it when they get in trouble." Addison smiled at her, happy that Kaitlyn was even speaking to her.

Addison whispered, "It is fun, isn't it?" Kaitlyn smiled. Even though she was definitely not happy with Addison at the moment, Kaitlyn thought it was nice to be with a familiar person. After all, at one time they were very close, and Addison was trying. Mark just wanted to get out of the room.

"Well?" He stood there annoyed and kept looking at his phone.

"It's just a cold, but see it took just a few minutes to do that and lecture you. Just take care of her next time." She rubbed Kaitlyn's back soothingly. "Take Tylenol for the fever, drink a lot fluids, and get some rest. You can find me or call me if you need anything." Addison's pager went off. "I have to go."

"Bye, Addison." He spoke to her with an attitude. He didn't particularly enjoy the lecture on parenthood from her. "Go find an on-call room to sleep in or something. I have things to get done here." He left her alone to wonder when she would get the attention she wanted.

The next day Kaitlyn was once again stuck in the hospital. She wandered the halls with nothing to do. Addison found her. Their interaction the day before didn't really change how she felt about Addison, especially without her father around to be angry at too.

"Kaitlyn, please talk to me."

"I don't want to."

"Why not?" Addison desperately wanted to have a good relationship with Kaitlyn once again. There were times when she also felt like an outcast in Seattle.

"Because you ruined everything, Addison." Kaitlyn walked away leaving Addison feeling sad, frustrated, hurt, and guilty.

Later Addison was relaxing in an on call room when Kaitlyn walked in. She saw Addison and turned around to leave. Addison stood up.

"Kaity."

"No, please leave me alone."

"The only way it's going to get better is if we talk about it." Addison pleaded with Kaitlyn. She desperately wanted things to be the way there were a few years ago. They were all happy then.

"Fine, but will you leave me alone then?"

"Yes. Just tell me exactly why you won't talk to me."

"You hurt Uncle Derek. You ruined your relationship with him. Then you moved in with my dad and I couldn't stand do see you two together, it wasn't right, so you drove me away too. Then, I had to live with my grandparents and then I was sent away from them. You drove my dad away too. You messed up everything!" Addison felt like she had been stabbed. She knew it was all her fault. She tried to reason with Kaitlyn.

"It was never my intention to hurt you or to take you away from your dad. Derek wasn't there. Your dad was. One thing led to another and I was just trying to get Derek's attention."

"You sure did that." She couldn't even look at Addison. She so badly wanted to go back to when life was easy and happy.

"It just happened. It wasn't planned. I wasn't thinking. If I could, I would take back everything, but I can't so I have to live with my bad life choices."

"I loved the way things were. Being with you, dad, and Uncle Derek was my favorite thing. I loved it and I loved all of you. I didn't want things to change. Everyone at school felt sorry for me because of my parents, but I told them that I had it better than them because I had three parents. Now I feel like I have none."

"I'm so so sorry. You shouldn't have gotten mixed up in our problems. We all should have realized that everything we do affects you. I want to get back to the way things were between you and me. "

"I can't…yet. I need space. My dad picked me up and moved me to the other side of the country. Can I get used to that first?"

"Yes. You have three people here who love you and will do anything for you."

"I know. I need time."

"Fair enough. Am I allowed to say hi to you if I see you?" She felt like she was making some progress and she was happy with that.

"Sure. Now can you leave me alone?"

"Yes. Can I check if you have a fever still first?"

"I guess." She knew she wasn't going to get away with saying no to that. Besides she knew Addison truly cared. She just needed some time to forgive her. Addison touched her forehead, which reminded Kaitlyn of the Addison she missed, who she had so many good times with. Tears began to fall down her cheeks. Kaitlyn wrapped her arms around Addison. Addison was surprised, but held her close. "This doesn't change what I said."

"It's okay. I will wait forever for you to be happy with me again." Kaitlyn held onto Addison for another minute.

"I miss you, but you are starting to be you again and you haven't been you for a little while. I need to make sure you are back first." Addison put her hands on Kaitlyn's face.

"I am back and I do love you." She smiled and kissed her forehead before walking out of the room. She turned around when she got to the door. "By the way, you do still feel warm, but you look better so you must feel better."

"I do." Kaitlyn smiled when Addison left. She knew that things were moving in the right direction.

Late that night Mark finally found Kaitlyn after searching the hospital for her. She was sound asleep in a bed.

"Kaitlyn. Where have you been? I had to search the whole hospital for you."

"It's late. I've been asleep."

"Let's go. We're leaving." She quickly jumped up and grabbed her stuff so she could catch up to him.

"I don't want to be here all day every day and night."

"I'm working. I work to support you."

"You like working. I know you take care of me like that. But I don't have to go with you."

"I don't think you should stay home by yourself so long when you don't have school. I don't like you being home alone." She gave up on that argument and followed him to the car.

Next day. Kaitlyn was once again stuck at the hospital. While wandering though the halls, she came across Cristina, Izzie, and Alex hiding in the basement hallway.

"So little Sloan." Kaitlyn turned to look at Cristina.

"Are you talking to me?"

"Yes. I'm talking to you. I want to know if you have any good gossip."

"Cristina. Leave her alone. She's only a kid."

"What? She knows things."

"I don't think we've officially met. I'm Izzie. That's Cristina. That's Alex."

"I've seen you around. I'm Kaitlyn."

"So you knew Shepherd back in New York?"

"You don't have to answer her."

"She had to know them. Shepherd and Sloan were best friends."

"Uncle Derek and Aunt Addison have been around since before I was born."

"Uncle Derek and Aunt Addison? Are they going to get back together?"

"I don't know. Uncle Derek has his new intern."

"Meredith. She's my person. What's the deal with McDreamy?" Kaitlyn looked at Izzie like Cristina was crazy.

"Yeah she's pushy. Just go with it. It's easier than making her stop."

"McDreamy?"

"Shepherd."

"You call him McDreamy? That's funny. I don't know what the deal is with anyone. I want my old life back. But I hardly speak to any of them now. Did you know Aunt Addie, Uncle Derek, and my Dad used to be so much fun? They've been my parents for a really long time. I want that back. Addison messed up so much. I guess my dad too. It does take two. And now Uncle Derek isn't himself."

"Interesting."

"You can sit with us. We're hiding from Dr. Bailey. You're probably looking for something to do." Kaitlyn looked back and forth between Cristina and Izzie. She choose to sit next to Izzie.

"I'm sure you know the gossip that surrounds my life. Are you going to tell me about you? Or Meredith? I'm sure she's nice and all."

"She's dark and twisty."

"Cristina. Tell her nice things. Her mom is a famous surgeon. She grew up in Seattle. She also has some kind of relationship with the chief. Not like a boyfriend relationship. Like a family friend. But we don't know what the deal is with that right now. We live with her. Well I do. And George."

"Izzie can ramble forever."

"It's okay. My dad leaves me here for hours with nothing to do."

"How old are you?"

"15."

"You're not a baby."

"My dad doesn't want me to stay home alone. I mean I don't really want to be home alone this long, but I don't want to be at the hospital all the time. In New York, I had 3 parents. One of them was usually with me after school and stuff."

"Maybe one day, you'll have that back."

"Izzie. Meredith, think of Meredith."

"Dr. Shepherd and Dr. Montgomery-Shepherd don't have to be together for her to have a relationship with them."

"I have Derek if I ask. I don't really have my dad. Just when he's doing the required parent things. And I don't have Addison. I could. She trying hard. And I want her back. It's just going to take some time. I feel like it's all her fault. I know it isn't really, but that's how I feel." Their pagers all went off.

"We have to go, but talk to us anytime!" They ran off and she continued her laps. She found Derek.

"Hi Sweetheart."

"Hi!"

"Where's your dad?"

"Who knows."

"Join me for lunch?"

"Just you and me?" He smiled at her.

"Yes. Our date. No Meredith. I think that's what you mean."

"Yeah. I want to meet her. But not yet."

"I get that. It's a lot of change for you to deal with." They walked off to lunch together.

A few days later Kaitlyn was once again stuck in the hospital after school. She didn't feel like moving so she sat on the floor of the hallway just watching everyone walk by. Addison actually noticed her.

"Hi." Kaitlyn looked up at her.

"Hi." Addison looked concerned.

"You don't look good."

"I don't feel good."

"Are you okay?"

"I don't know. My dad says it's another cold."

"Did he listen to you cough?" Kaitlyn shook her head. "Take your temperature at least?" Kaitlyn coughed.

"No."

"Do anything?" Kaitlyn shook her head.

"Come with me." Kaitlyn stood up and followed Addison without a complaint. Addison had consistently been the person Kaitlyn wanted in her life this week. She was ready to feel cared for.

Kaitlyn followed Addison into an exam room. Addison examined Kaitlyn. Kaitlyn kept coughing.

"It hurts."

"I know. You feel so warm."

"Why doesn't my dad love me anymore?"

"Oh sweetheart. He loves you so much. We all do. He's not himself. We all are working on that. He's still finding his place in Seattle. Until you came, he's been, well, Mark. You know. Like he used to be. But he doesn't want that for you. I think he's trying to figure himself out and how to balance being a father, a surgeon, and his social life. It's not like in New York when we all practically lived together. Your dad, Uncle Derek, and I have a lot to work out to say the least, but we all will do anything for you." Kaitlyn started crying.

"I want you to be friends again." Addison hugged her and kissed her forehead.

"We will be." Kaitlyn coughed again. "We need to do something about that. You have pneumonia. You're going to be fine. You just need a lot of rest and antibiotics. You'll get better. I need to find your dad. Will you be okay waiting here?" Kaitlyn nodded. Addison found Mark looking at the surgery board.

"How many times do I have to tell you to take care of your daughter?"

"I do take care of her."

"Well I bet you don't know where she is."

"I do."

"She's crying in an exam room. She has pneumonia. Sign this so I can do a chest x-ray." He signed the chart she was holding in front of him. Deep down he knew he was wrong and he trusted Addison with his life, with his child's life no matter how little he liked her at any moment.

"You know it's just a cold."

"It's not. And you would know that if you took even 30 seconds to take care of her."

"Jeez Addison, stop bossing me around."

Addison found Derek on her way back to Kaitlyn. He was in normal clothes, not the usual scrubs.

"Are you off?"

"Yeah."

"At what point do we take Kaitlyn from Mark?"

"You can't just take someone's daughter from them, besides she doesn't really like you right now."

"Last week I happened to walk by while Mark was arguing with Kaitlyn. Kaity was trying to tell him that she didn't feel well and he was essentially ignoring her. I lectured him while examining her."Derek was surprised.

"She let you examine her?"

"She doesn't like me, but we're still family. She knows me and she knows I was helping her. Anyway, he didn't get the point. She's sick again. Mark's doing nothing for her."

"It's probably the climate and change in location."

"It's still pneumonia and she still needs to be taken care of. Since you are off, will you take her and watch her for a while? I would, but as you didn't hesitate to point out, I'm not her favorite person at the moment and I have to work."

"Sure. Where is she?"

Only about an hour later, Addison's phone rang. She saw that it was Derek.

"What's up?"

"Hey. Where you paged for the fire?"

"It's a senior citizen home."

"So that's a no?"

"Yes that's a no, Derek."

"Can you trade places with me?"

"Yeah. I'll come over now."

"No stay there. I'm at the pharmacy. I'll be at the hospital in a few minutes and then you can take her medicine to her."

"Okay. I'll wait for you in the pit."

Addison entered Derek's trailer with bags in her hand. She found Kaitlyn on the couch.

"I know you don't want me, but it's a fire. Your dad and Uncle Derek are both needed. Plus, I come bearing gifts." Kaitlyn smiled at her. She actually was happy that Addison was there. She missed having a mom, especially when she was sick. Addison started pulling things out of the bag. "Medicine, chicken noodle soup and Aladdin."

"Yay."

"Go get comfortable on Uncle Derek's bed and I'll put your soup in something easier for you to eat in bed." Addison came in the room a few minutes later. "Okay. Medicine first." She handed it to Kaitlyn, then started the movie.

"Will you sit with me?" Addison smiled.

"Of course. Plus I would like to watch Aladdin too." After a while Kaitlyn fell asleep. Addison decided to take a shower. She had been at the hospital more than an entire day. It had been a while since she was able to take a shower. She put on a pair of sweatpants that she found in Derek's closet and one of his t-shirts. The door opened as she was combing her wet hair. She turned and Meredith entered. She looked shocked to say the least. She started to leave.

"Meredith. It's not what it looks like." Meredith turned back around.

"What is it then."

"Kaitlyn's sick. Derek was off so he took her home with him, Derek got called back in because of the fire so I switched with him rather than move the sick kid all over the city."

"Oh. Why are you in his clothes?"

"I hadn't left the hospital in 36 hours. I desperately needed to shower and get comfortable. Were you not paged?"

"No. What happened?"

"A big fire. Lots of injuries."

"No pregnant women?"

"It was a senior citizen home." Meredith smiled.

"Oh. So I guess I'll just go. I was coming to see Derek."

"Kaitlyn's asleep or I'd say you could say hi to her."

"We haven't officially met yet. I heard she doesn't exactly like me. She's not in the position to like both you and me."

"Well, I'm not her favorite person at the moment either. In her eyes, I ruined everything." Meredith did say anything. She kind of felt the same way at one point.

Days later…

Kaitlyn went into the living room where Mark was. Something was clearly upsetting her.

"I need Aunt Addie."

"Why?"

"Please take me to her."

"So are you talking to her?"

"Please? I really need her."

"Fine, but I might have to leave you with her for a while."

"Okay. I don't want you there anyway." Mark took Kaitlyn to Addison. Addison opened the door when they knocked.

"She needs you for some unknown reason, but I have to leave her with you."

"Okay. That's fine." Mark walked away. "You look like you're going to cry."

"I don't hate you. You're my family. You, dad, and Uncle Derek. I love you all. I was mad at you for what you did, but much more mad at my dad for coming between you two."

"That wasn't our only problem."

"But still. When I moved back in with my dad, I couldn't always be mad at him so the anger all went to you, but I miss you and I need you. I wanted you so much this past week, but I was too stubborn to admit it." Addison hugged Kaitlyn, who was kind of crying.

"What's bothering you?"

"I have a problem that kind of fits in your specialty."

"Ah, I see why you came."

"That's not why I made up with you. I really do miss you and want to be around you."

"I know. I'm teasing. I wouldn't tell my dad those problems anyway. So…"
