A/N I had no idea that I would get reviews begging me to continue. So I have officially decided to extend this. Oh and all of the chapter titles are song titles.

Judas

In just two days Derek and Addison's lives had changed dramatically. They had turned in their resignations to Richard and they had been on a plane to New York. They were now standing in front of their brownstone together for the first time since Derek had caught Addison with Mark. Derek still had the keys and he had just put them in the keyhole. He turned the key and pushed the door open and suddenly memories of that night flooded his brain.

He remembered walking to his house and setting his keys on the table by the door. He startled walking up the stairs and then he stepped on a leather jacket that he recognized. It belonged to his best friend Mark. Derek remembered the sick feeling in his stomach when he realized that his wife was cheating on him with his best friend. Derek remembered walking in on them having sex in his bedroom that he was supposed to be sharing with his wife. He remembered the fact that they were having sex on his favorite flannel sheets.

Derek remembered that both Mark and Addison froze when they realized he was in the doorway. Mark had grabbed his clothes and went out the window. He knew he had no other option. He knew that going past Derek was likely to get him killed. Derek had to admire Mark's glimmer of common sense there.

Derek remembered what he had done to Addison's clothes. He remembered screaming at her as he ran down the stairs with an armful of her clothes. He remembered her begging him to listen to her. Derek was still so hurt that the idea of listening to her made him sick. He didn't want to know why they had slept together. All he needed to know was that they had slept together. That was all he could handle knowing at that time.

"Derek, Derek, Derek, you can't do this, Derek. Derek, we have to, we have to talk about this. You have to give me a chance to explain. What are you doing? What are you doing with my clothes, Derek?! It was one time. I know that's what people say. I know that is what always gets said. It's just I don't even know how it happened, I don't know what I was thinking. It was just he was just here, it was just-""You screw my best friend and all you have to say is, 'He was just here?' Get out.""No.""Get out!""No, no I'm not going.""Get out of my house now!"

Derek remembered Addison begging him to stay. He remembered the tears in her eyes as she clung to him. For a split second that night he had considered staying, but then he realized that he couldn't look at her without seeing his best friend on top of her. No one but Derek was supposed to be on top of her. She had been his wife for eleven years and she had thrown it all away for a brief fuck with his best friend.

Addison remembered what she had said to Derek that night. She was desperate not to lose him because of a stupid mistake. That's what it had been. A really stupid mistake that Addison just wanted to take back. She loved her husband. Addison had never been clearer on that then right after she had been caught with his best friend. Addison remembered insisting that they could survive this. She remembered standing at the base of the staircase half crying and half begging Derek to stay with her.

"We can survive this. We're Addison and Derek!"

Addison remembered the desperation in her voice as she tried to convince Derek that they still were Addison and Derek. She didn't want him to leave her. She remembered the coldness in Derek's voice when he spoke to her for the last time before he left the brownstone.

"I can't look at you. I look at you and feel nauseous ... we're not Derek and Addison anymore."

Addison remembered sitting on the steps for hours after he had left. She couldn't bring herself to go upstairs. She stayed downstairs for the rest of the night completely avoiding going upstairs. She wasn't ready to face the scene of the betrayal. She drank an entire bottle of expensive red wine that night.

Derek looked at Addison and they both could tell that they were thinking the same thing. Both of them wanted to put the past behind them and they were both committed to working on that. Addison ran her hand over the oak wood banister that had been the beginning of quite a few sexual encounters between them. She smiled at Derek and Derek smiled back at her. Derek was happy to be back in New York with Addison. He was not a flannel wearing wood chopping fisherman as Addison had called him once before they left Seattle. He belonged in New York with his wife.

"I'm happy to be home." Derek admitted as he looked around.

"Me too Der." Addison told him softly before she brushed her lips lightly across his. Derek smirked into the kiss and he wrapped his arms around his wife and kissed her back, pressing her lightly into the banister.

"Ow." Addison mumbled against Derek's lips. Derek pulled away and pulled Addison's body off of the banister. He was about to go in for another kiss when they both heard a creak coming from the basement. Neither Addison nor Derek had any idea what was going on. Addison wouldn't admit that she was actually scared. The brownstone hadn't been occupied in awhile so God knew what could be down there. Addison grabbed onto Derek's hand and Derek and Addison made their way to the basement door. They opened it and the creaking only got louder. Now it was accompanied by mutterings.

"Shit. Damn it."

Both Addison and Derek knew that voice well. Derek had grown up with that voice and it had been a part of Addison's life for about twenty years.

"Mark?" Addison demanded completely shocked. What the heck was Mark doing in the Shepherds basement. Derek was the one who voiced that very question.

"What the hell are you doing here?" Derek demanded.

Mark looked up and he was startled to see them there together. They were holding hands so Mark assumed that Derek had forgiven her and they were trying to get their marriage back on track. He wondered what they were doing there. Weren't they living in Seattle now? Mark was slightly confused but he figured that he should answer Derek's question first.

"I came by to pick up my bike." Mark told the both of them. He meant his motorcycle that he had bought about ten years ago. It was still in great working order even ten years later.

"Why?" Addison asked. Now it was her turn to be confused.

"I'm selling it." Mark told Addison.

Addison raised an eyebrow. Usually the reason that men gave up their toys like a motorcycle was that they were seeing someone who didn't want them riding the bike. It was usually a woman that they were pretty serious about.

"Who is she Mark?" Addison asked knowingly.

Now Derek looked confused. He had no idea why Mark would sell his bike that he had had for ten years. He had no idea why Addison seemed sure that it was a woman that had incited this change in Mark. Mark wasn't surprised by Addison's question. She knew him well. Not just sexually, but emotionally as well.

"Brianna. She's a nurse at Mt Sinai." Mark explained.

Now it was Derek's eyes turn to widen. Addison had been right. It was a woman that had incited this change in Mark.

"Wait a minute, why are you guys here? Together? "Mark demanded, feeling it was high time he got his questions answered.

Derek and Addison exchanged glances and smiled at each other. They knew what they were doing here and it had been the right decision to come back to New York.

"We came home." Derek explained before he kissed Addison's pale cheek.

"We're going to give us another shot. We knew we couldn't do it in Seattle. We wanted to return to New York." Addison explained with a bright smile on her face.

Mark was so glad to see that his two best friends had returned home. He just wasn't sure if he would ever have his best friend back. He had totally messed up and he hoped that Derek could forgive him. Even if it took years, Mark was willing to wait.

Derek looked at Mark, knowing that Mark wasn't sure if Derek would ever forgive him. Derek knew that there was no way he would ever forget what had happened, but since had forgiven Addison, he could do the same for Mark. Mark was his brother and he had been ever since they were eight years old.

"How about a drink?" Derek suggested, looking at Addison and then at Mark. Addison looked at Derek with a smile on her face. She was so glad that it appeared that her husband was willing to forgive his childhood best friend for betraying his trust. Mark was stunned that Derek wasn't going to bash his head in for sleeping with Addison, but Mark guessed it was best not to look a gift horse in the mouth so to speak.

"I'd like that." Mark agreed quietly with a nod.

"Bring Brianna." Addison suggested. Mark looked at Addison knowing that she was probably up to something. None of his girlfriends in the past had ever passed the "Does Mark's Latest Fling Have A Brain" test that Addison had set before them so Mark was nervous. Derek on the other hand didn't think that tonight they should involve a virtual stranger. Derek wanted tonight to be their night. He wanted to reconnect with Mark and start to rebuild their friendship.

"No let's have it just be us tonight." Derek suggested. Mark and Addison exchanged glances and nodded. That sounded like a good idea.

"I'll meet you two at our place at seven." Mark promised. The place he was referring to was their favorite place to get drinks. It was kind of like Joe's in Seattle, but this one was more upscale and Addison liked this one better than the one in Seattle.

"Sounds good." Derek told Mark as Mark headed back up the stairs, his bike totally forgotten. Mark was back in his best friend's good graces and he was looking forward to being able to put everything behind them.

------------------------------------------------------------------------------------------------------------------------------

Once Mark was gone, Derek and Addison went back up the stairs to the main floor. Addison looked up the stairs and looked at Derek. She was ready to go up there with Derek and she hoped that he was ready too. Besides she had to pick out something to wear to drinks with Derek and Mark tonight. Addison held onto his hand as they made their way upstairs. When they walked into the Master suite, Derek shut his eyes to rid his mind of the images that had plagued him for week. They never came. He opened his eyes and his wife was standing beside him.

"You okay?" Addison asked him softly.

"Yeah." Derek told her softly. He wasn't lying to her. He was really okay and he was glad that Addison was standing beside him. He was looking forward to starting their life together. They were getting a second chance and Derek knew how rare those were.

Addison could tell that he was happy and she was glad to see that. She was so glad that Derek didn't seem to regret coming home with her.

"Can you help me pick out a dress?" Addison asked as she walked over to her walk in closet. A lot of her clothes were still in there and now she was looking through them.

"You know you look beautiful in whatever you wear." Derek reassured his wife as he wrapped his arms around her slim waist. He nuzzled his nose against her neck as he continued to hold her close. Addison shivered when she felt Derek's nose against her neck

"How about this?" Addison asked as she held up a deep blue dress with a silver buckle around the waist.

"Beautiful." Derek told her reassuringly. He let his lips graze her neck and Addison shivered. She turned around in his arms and whispered "Kiss me Der." Derek could think of nothing else he'd like better to do than to kiss his wife. He pressed his lips softly against his wife's rosy pink lips. He put his hands on her waist, while Addison's arms encircled his neck. He wanted to make love to her, but he wasn't sure that was what she wanted. He did not want to rush their reconciliation.

"I am going to go shower." Addison whispered.

"I'll join you." Derek suggested with a grin.

"Fine Der, but no sex." Addison told him seriously. Derek bit back a groan, but he didn't argue with her. He didn't want to rush her.

------------------------------------------------------------------------------------------------------------------------------

Derek had gotten into the shower first and Addison followed him. Addison knew that Derek had seen her naked hundreds of times, but she still felt a little shy when she stepped into the shower. Derek looked at her body and he wondered how he was going to keep from running his hands all over her body. Then he remembered, she had never said that he couldn't touch her. He leaned in and brushed his lips tenderly across hers. His hands ran slowly down her slim body, trying to ignore the desperate desire that he had to be inside of her.

"Der." Addison whispered.

"Yeah babe?" Derek asked his wife.

"I love you." Addison told Derek softly before she deepened the kiss and ran her hands down his back.

"I love you too." Derek whispered back before he ran his hands down her back

They both knew that eventually they would have to actually use the soap but right now they were remembering each other's bodies. It had been awhile since they had both been as intimate as they were right now. Touching each other's bodies just felt like coming home for both of them.

--------------------------------------------------------------------------------------------------------------------------------

When they stepped out of the shower, Derek went to put on a nice shirt and a nice pair of pants. Addison slipped her bra on and her panties. She wasn't going to get dressed right away because she didn't want the dress to get water on it from her hair. Derek watched her and he couldn't help but look forward to forever with her. When Addison had her hair up so the dress wouldn't get wet, Addison put the dress on one foot at a time and then she drew it up over her body.

"Zip me up." Addison whispered when it was all the way up. Derek smiled and he kissed the back of her neck before he zipped her dress up.

"You look beautiful Addie." Derek told her with pride in his voice. She was his. Addison loved him and he still loved her despite everything they had been through.

"Thank you." Addison murmured as she slipped her wedding ring and engagement ring back on. She saw that Derek already had his wedding ring on and that made her smile. Seeing him wear it a lot was a new thrill for her.

"Let's go. We don't want to be late to meet Mark." Derek reminded his wife. Addison checked her watch and she was startled to realize that it was already six thirty. Addison grabbed her purse and put her blue Prada pumps on and she took Derek's arm. They left the brownstone looking forward to an evening at the bar with their best friend.
