What if Seth had a twin sister , who had had a huge fight with Sandy lets say just before the first season started and Ryan entered the family. She had had enough, and said she needed a time out, so she ran away. No one had seen her since. What if she suddenly came back?

It was soon Chrismukkah and Kirsten had been out shopping gifts.She pulled up on the drive way outside "Casa Cohen". She left all her bags in the car to go and unlock the door , when she saw something lying outside the frontdoor. It was a person.

Kirsten bend down to look closer, she had a shock when she recognised the girl. It was her daughter, Kelly.

"Oh my God", Kirsten whispered. "Kelly? Kelly wake up!"

She didn't. But she was breathing.

"I need to get her inside the house", Kirsten thought, as she wondered how the hell she would manage to carry her 16 year old girl into the livingroom. She decided she would call Sandy.

"Mr. Cohen is currently in a meeting and you won't be able to reach him before 4 pm"

Crap. Seth and Ryan were at school. She serously doubted Julie would be home in the middle of the day. She went out on the street, looking for someone who could help her, when Taryn and her husband Charlie walked past.

"Hello Kirsten", Taryn smiled.

"Hi Taryn and Charlie", Kirsten said, looking back towards the house, getting an idea.

"Ehm…Charlie, do you think you could help me with something?", she asked , hoping he would.

"Yeah sure Kirsten. What do you need?" , Charlie answered also looking towards her house.

"Come", Kirsten said as she started to walk quickly back to where Kelly were lying.

"Ehm..Who is this?" , Taryn asked when they reached the Cohen's frontdoor.

"Don't you remember our daughter, Kelly?", Kirsten looked at her.

"Oh my God! Is that Kelly? I thought you said she wasn't coming back"

"I never said that!", Kirsten frowned."Anyways, Charlie, do you think you could carry her to the livingroom couch?"

"Sure", he said as he lifted her up easily, walking through the door Kirsten was holding open.

He put her down on the couch in front of the tv.

"Thanks.And sorry to bother you", Kirsten said.

"Oh no problem.We 're just glad we could be of help", Charlie smiled." Well, goodbye,then. And good luck"

They left.

Kirsten looked down at her daughter's face. She looked so like her it was scary. The eyes, the face, like a copy of Kirsten's. But she had black hair like Sandy.

Kirsten noticed a bruise under her left eye.

"Wonder what happened", she thought."Well, I don't think she will be waking up in a while,but I'm sure it isn't serious."

Kirsten went into the kitchen and grabbed a cup of coffee. Kirsten couldn't help but wondering why Kelly was back. Not that she didn't want her to be back, they used to be like best friends, no she was more concerned about how Sandy would react.

At the firm where Sandy were working , he thought about what had been said between him and Kirsten two days ago. She was clearly upset about the fact that they were going to celebrate the holiday without Kelly. He had told her that Kelly would be back sooner or later…But he didn't even believe that himself, and he don't think it convinced his wife. He knew it was his fault that Kelly ran away…Just because that stupid fight. He had gone off on her because several days in a row she had come pretty late, and she had been drunk. One night Sandy even thought she'd been high.

Kirsten heard a noise from the couch and hurried to it. Kelly slowly opened her eyes and looked into her mother's almost identical blue eyes.

"Hey mum", she said with a quite raspy voice.

"Hey honey", Kirsten said happily, and hugged her daughter.

Kelly started crying when she felt her mother's warm embrace. They sat in each others arms for a moment, until Kirsten pulled away.

"Can I ask why you are here?". She didn't exactly want to ask that question, but she had to know what Kelly was up to.

Kelly looked at her with tears in her eyes,. She knew Kirsten would ask her that. And she had an answer.

"I'm soo sorry. I understand that you must have been terrified and upset, but it wasn't your fault, or dad's…"

"But I thought you left because you two had a fight", Kirsten was a bit confused. Was it something else that bothered her , something she didn't know anything about…

"Well, but I know it was totally my fault and…and….", she just lost it. Tears streamed down her cheeks.

"Oh honey! It's ok."Kirsten hugged her again."Are you here because you want to stay …or…."

Kelly pulled away.

"Can I stay? I know I've been a bitch, but please forgive me! I really want to stay here with you guys", she said,upset."If dad will forgive me" , she added quietly.

"Of course he will. I don't think he can stand kicking you out of this house.Plus, I won't let him. I've missed you", Kirsten laughed a little.

"Thanks. Can I have a cup of coffee?"

"Come on, time to catch up.", Kirsten said as they went to the kitchen to get some coffee, and maybe a bagel with cream cheese…

At school, Anna thought Seth was acting a bit weird, he was unusually quiet. She asked him if anything was wrong, and he answered:

"Well, it's just a …thing."

"What kind of thing? Anything serious?"

"It's… a family thing. You see, this will be the first Chrismukkah without Kelly…"

"Who's Kelly?" Anna asked curiously.

"Oh, it's….it's my sister. We're twins", Seth started to regret what he had just said, Ryan didn't even know about Kelly.

"Oh, I didn't know you had a sister", Anna didn't know if she dared asking the question she had in her mind, but she couldn't stop it. "What happened to her? Is she…?"

"No. She ran away. It was like a huge fight.Do you want to come with me to the comicbook shop after school?", he really didn't want to talk about his sister right now.

"Ok." Anna said, knowing Seth didn't wish to discuss the subject further.

Kirsten and Kelly sat at the kitchen table, talking and laughing. It felt like the good old times, when they could talk about almost everything.Suddenly Kelly became serious.

"Do you really think dad will forgive me?"

"He will", Kirsten reassured her, smiling her sweet smile, so like Kelly's own.

They heard the front door opening, and Sandy's voice calling "Kirsten, I'm home"

"Go to the couch and keep quiet, we're going to give him a big surprise" Kirsten whispered quickly as she got to her feet to go and meet her husband and Kelly went to hide in the couch.

"Hey honey! You're early" , Kirsten said as she greeted him with a kiss.

"I know, I figured maybe we could go and buy a Chrismukkah tree. Are you going somewhere?". He just noticed a quite dirty bag lying on the kitchen floor, who belonged to Kelly.

"Ehm…no. Sandy, there's something I need to tell you.You were right."

Sandy was confused. "You know, I really like it when you're saying that I was right, but what the hell are you talking about?"

"Kirsten didn't answered, she just smiled and waited for Kelly to speak.

Kelly realised from her mothers silence that this was the right time.

"She is talking about me"

Kelly got up from the couch and looked at her stunned father

"I'm home"
