Hey guys,

I decided to write another Addek one shot, but when I started writing, I noticed it would be a bit longer, so I made it a two shot. I had this idea during watching Private Practice again.

Some information:

- The story is set in GA season 1, somewhere in the middle.

- The song I listened to while writing is "Hide & Seek" by Imogen Heap. so I named this story after the song.

Disclaimer: I don't own anything.

So, have fun and I would be really happy if you reviewed.

Love Mariella

Hide & Seek

Chapter 1

Derek Shepherd liked Seattle so far. SGH was a good hospital, he liked his colleagues and right now Meredith Grey was with him in his trailer and things were heating up fast. She was so young and different from … no, he couldn't think of her now. He tried to stay in the present, but snippets were coming to his mind, how her red hair looked in the bright sun of Central Park, how it took him month to convince her to go out with him, how she looked when she smiled and how it felt when he kissed her. Derek and Meredith were in bed by now and short time later. When Derek had his orgasm, he whispered in Meredith ear. "Oh Addison." Meredith felt like frozen on the spot. Did he just call her by another woman's name?! She pulled back quickly, which made Derek look at her confused, obviously he hadn't noticed that he called her by the wrong name, which made the anger grow. "Seriously?" Meredith screamed at him. Derek, who felt quite comfortable until now, looked at her confused. "What are you talking about?"

"Who's Addison?"
Derek looked at her shocked. "What?"

"You were calling me Addison during we had sex!"

"I …" Derek felt lost at word. "I'm sorry Meredith, it was a slip of the tongue."
Meredith looked at him even more mad. "Who the hell is Addison then?"
"She's … somebody that I used to know back in NY."

"That's all I get? Seriously? You know what, I will go now, because you can't say another woman's name during sex and then only say, that she is someone you used to know!" Meredith screamed at him and stormed out of the trailer. Derek was left speechless. Why had he called Meredith Addison? He wanted nothing more than leave his old life behind and start over. He sighed and helped himself to a glass of Scotch. He should apologize to Meredith the next day and try to explain with really telling her, who Addison was. Things were becoming really complicated by now.

Meredith entered meanwhile her house, where all interns were watching a movie. Christina looked up, when Meredith entered. "Hey Mer, thought you would be at McDreamy's?"

Meredith only shrugged and went to her room with Christina following close behind. She stood in the doorframe for a while, until she asked. "So, you gonna tell me what happened?"
"He called me Addison."
"Who?"
"Derek, during sex, he called me Addison."
"Did you confront him?"
"Yeah and he only said that she was someone he used to know back in NY."

Christina smiled smugly and got a notebook. "So, what's the problem? There's something called internet."
She searched for a while until she found a photo of Derek, an unknown woman and man. They were smiling brightly and the woman was standing between the two men. Meredith looked at the screen now too. Christina scrolled down and saw what was written under the photo "9th annual Gala for Cancer-Patients at Mt. Sinai, NY. from left to right: Dr. Derek Shepherd, Dr. Addison Montgomery-Shepherd and Dr. Mark Sloan"

"What?" Meredith was shocked. She looked at the woman again, she was tall, skinny and looked absolutely stunning in her deep blue gown, which matched perfectly Derek's tie perfectly. But what freaked her out most was her name Addison Montgomery-SHEPHERD!

"Maybe she's his sister." Christina tried to calm Meredith down.

"Why should he say his sister's name during sex?"
"Ok, you have a point here." Christina told her and started to search again, but this time she didn't search for Derek Shepherd but Addison Montgomery-Shepherd. Short time later she had found an article about Derek, Addison and Mark, in which they were praised for their excellent work at Mt. Sinai and in which stood "Dr. Derek Shepherd and Dr. Mark Sloan had known each other since they were kids. They met Dr. Addison Montgomery-Shepherd during med school and Derek Shepherd added here "The moment I saw her, I fell in love with her and knew that she was the one for me, the one I would be marrying someday." By now the two Shepherds are married for 9 years." Christina looked at the date of the article, which was dated two years ago. Meredith looked miserable by now. "Hey Mer, maybe they are divorced."

Meredith didn't look at her, but searched for more photos and on most of them she found Derek and Addison standing close and in many pictures he was lovingly smiling at her like he was the happiest guy ever that she chose to be with him. She only found one picture taken of Mark and Addison, in which it seemed like Mark had taken Derek's spot. "I don't know … what if he's still married."
"But he left her, right?!"

"Right."
"But he called her name … maybe you should talk to him tomorrow."
"First thing in the morning." Meredith told her.

Derek woke up the next morning and felt quiet bad, because of the alcohol and because of his dreams. He had seen Addison over and over again. Her hurt face when he left and told her they weren't Derek-and-Addison anymore. Had he left too soon? Had he given up to quickly? But she cheated on him, he had found her with his best friend in their bed and beside all anger her felt hurt like never before, it was like a slap straight in the face. He hated her for what she did, but could he really hate her completely?! Also Mark words were echoing in his head "She misses you Derek. You are absent and don't care like you did before. Be careful, because eventually she will move on and leave you, because she's Addison and she won't keep waiting forever. She will fall in love with someone else and will leave you if you will stay absent." He had brushed it away at the time. He never really thought Addison would move on without him. He never expected her to move on and never with Mark Sloan. He entered SGH still deep in thought and went to his office to go over some charts. Short time after he entered, he heard a knock. "Come in."

Meredith entered with lots of papers. "So, you say Addison is someone you used to know. These are all printed articles about you AND Addison Montgomery-SHEPHERD." She stated.

"Meredith … she's my wife."
Meredith couldn't stop the tears that were in her eyes by now. "You are married and don't think this would be maybe important to me if we're in a relationship."
"I … left her."
"Why?"

"I really don't wanna talk about that."
"So you know what, you don't have to, because I don't care. Not about you or your freaking wife. Your freaking wife, who finished high school early top of her year, who went to med school with you and was top of your year there too, who is not only a world-class neonatal surgeon, but has a board certifications in Obstetrics and Gynecology AND Maternal and Fetal Medicine. You know I had some really bad relationships in my life, but this is the worst, because I thought things would be different, that we could really be something, but you have this wife you don't want to talk about, but know what, even though you are mad at her for some unknown reason, there will be the day when you notice what you lost, because after I read as much as I could in the internet yesterday … you can't hate her forever, because she's brilliant and she saves babies. So if you aren't finished hating her, please let me be, because I am hurt now, but I will be even more hurt, when we continue this and in the end you choose her over me." Before Derek had the chance to reply Meredith turned around and left.

Derek looked at the articles and photographs Meredith had brought with her. He noticed one photo instantly. It was of him and Addison up, which was taken about 3 years ago at a charity event for the Met opera. They looked so happy and in love and Addison was breathtaking beautiful. Then he noticed another photo, it was taken at the Met opera charity event last year. It was of Addison and Mark, Addison looked still breathtaking, but her eyes didn't match her smile. She looked sad and he only noticed now, that she looked scarily skinny. What had he done? She was always the strong one, got over all her issues and stood up for herself and others, but when he looked at the last photo taken of her now she seemed broken and not like herself. He stood up, because he couldn't stand to sit around anymore.
