Ten years later and Addison and Derek were happily married, much to Archer's dismay. He still couldn't stand Derek, but he put on a front for his sister, being civil towards Derek and acting like they were actually friends instead of the hated enemies that they were. Addison believed that Archer did now like Derek and that Derek liked Archer, but she was so wrong. They were just putting on a show for her so she felt better about them. Happy about the fact that her husband and brother got along she would insist that the three of them went out to dinner, even though both men always hated the idea of having to spend the night with the other.

Addison's parents had come to accept the fact that their daughter was with Derek, no matter what they said and they knew that she would eventually end up hurt by him, but there was nothing they could say or do, apart from just watch. They had after a few years come to like Derek as a person and they saw how happy Addison was and they slowly began to doubt their first thoughts. Maybe they had been wrong.

Feeling the need of both her brother and her husband's presence she arranged a dinner out at her favourite restaurant for both of them. She was really excited about spending the night with the two guys she loved and made sure that she looked presentable.

Addison waited for Derek to come home that night but all she got was a phone call from a nurse, telling her that he had been called into a surgery and that he wouldn't be home until late, if he did mange to get home. Addison hung up disappointed, before making her way out to her car and driving to the restaurant to meet Archer.

"Hey baby sis." Archer smiled at Addison as she sat down at the table with him.

"Hey." Addison smiled back and sat down. "Have you ordered yet?"

"No, I was waiting for you and Derek." Archer frowned as he didn't see Derek anywhere. "Where is Derek?"

Addison looked down and avoided her brother's gaze as she picked up her menu to order. "He's in surgery, he won't make it."

Archer watched her body language and he knew that something was wrong. He knew that Derek had missed a lot of dinners lately. At first he just thought it was because Derek didn't want to spend the night with him, but then Archer found out that it wasn't just dinners with him, it was dinners with everyone.

"He booked a surgery for now?" Archer raised an eyebrow.

"No." Addison shook her head. "An emergency Surgery."

"Couldn't someone else have done it?"

"No." Addison shook her head again, but in truth, she didn't know, someone else probably could have.

"Hmm. He's missed a lot of dinners lately hasn't he?" Archer watched as his sister tensed at his words, still refusing to meet his gaze.

"He's been busy with work. He's been needed in surgery to save someone's life." She defended her husband but she knew what Archer meant. Derek had missed a lot of dinners and she was starting to miss him.

"But I'm sure other surgeons are very capable of doing the surgery. He's not the only neuro surgeon there is." Archer set his menu down. "You are more important than work."

"Archer." Addison warned and looked at him, but not looking him in the eye.

"Okay, okay." Archer held up his hands. "I'm just saying, I don't want you to get hurt."

"I'm fine. He's just working."

Archer sighed and just watched his sister. He didn't say anything more, knowing she would just become upset and he wanted to make her happy for the night. He put a smile on his face and he became the typical Archer that was her brother, the one that could make her laugh and smile. They enjoyed the evening together like they used to when they were younger before Archer made sure she got home safely before he made his way to the hospital.

Archer stepped onto the elevator after what he guessed were interns stepping off to head home. He knew someone else who should be heading home but wasn't. He stepped inside and hit the button for the surgical floor, watching as the doors closed and the elevator made it's way to the requested floor, not stopping once. Archer got off the elevator and looked around, seeing that there wasn't many people on the surgical floor at this time. He smiled at a few nurses as he passed, making his way along before he spotted the person he was searching for by the surgical board. Without saying anything Archer walked up to Derek and stood next to him.

"Why are you not at home?" Archer didn't look at Derek as he spoke and Derek didn't bother to look at Archer.

"I'm working."

"You knew she made reservations for us to have dinner tonight."

"I was called into an emergency surgery."

Archer let his eyes scan the board, seeing Derek's name under a surgery that he had obviously just come out of. From the name Archer could tell instantly that a resident could have performed the surgery.

"Which someone else could have done." Archer quipped.

"There was no one else."

"Bullshit." Archer turned and stood square to Derek, watching as Derek turned to look at him as well. "You chose a surgery over your wife. A surgery that someone else could have done. You're not God, Derek. You can't save everyone. You have a wife to go home to. A wife who wants you home."

"I know that." Derek tensed his jaw, clenching his hands into fists. He would love to just punch Archer in the face but he contained himself for Addison's sake.

"Then why are you still here and not with her?"

"I'm working." Derek repeated from earlier.

"No, you're not. You're choosing to work. You're not meant to be here right now. Go home."

"You don't get to tell me what to do."

"You're hurting her by doing this. You're hurting your wife. Can't you see she misses you? Are you that blind? Go home to her, Derek. Go home and make her happy, because I swear to God if you keep hurting her…"

Archer trailed off, letting his threat just hang in the air and Derek could see in his brother-in-law's eyes that he meant it.

"I'll go change and go home." Derek looked at Archer and relaxed his fists. It would be nice to snuggle up to his wife and fall asleep. It would be even nicer to make love to her first.

"Good." Archer nodded, satisfied with Derek's answer. "She deserves better than you, you know."

"I know." Derek nodded as well. "She deserves the best." Derek turned, walking to the attendings' locker room to change.

Archer sighed and watched him disappear before he turned and left the hospital, getting into his car and driving home, hoping that Derek did in fact go home to Addison and make her happy. As loyal as he was to Addison, if Derek hurt her he would kick Derek's ass, literally.

Derek had made his way straight home that night after Archer's threat and he tiredly unlocked his front door and walked in. He saw that downstairs was in darkness and he locked the front door behind him, before placing his keys on the side and slipping out of his shoes before hanging his coat up. He placed his briefcase on the floor, deciding to move it in the morning. Quietly he tiptoed up the stairs, not wanting to wake Addison if she was already asleep. He made his way into the bedroom and smiled when he saw Addison snuggled up under the covers and he quickly changed before sliding in next to her, pulling her close and kissing her forehead.

"Derek?" She mumbled and her eyes fluttered open as she looked up at him.

"Hey, sorry, I didn't mean to wake you." He whispered.

"It's okay." She gave a small yawn. "I was just dozing."

Derek smiled as he looked at her sleepy state and kissed her nose, watching as she scrunched her nose up at him. "I love you." He whispered.

"I love you too, Derek." Addison smiled happily at him and kissed him softly on the lips. "I didn't think you were coming home tonight."

"I finished the surgery early. I'm all yours now."

"Good." She smiled and kissed him again, wrapping her arms around his neck before he rolled them over so he lay above her, his hands moving up and down her body, softly caressing her.

They spent the night making sweet love to each other, enjoying the other's body.

After that night things changed, Derek stopped missing dinners and began spending more time with his wife and Archer was glad of it, happy to see his sister smile more. Archer still reminded Derek every now and then not to hurt Addison, even though he knew that Derek eventually would, but he would still remind Derek.

For a whole year Archer watched the couple be happy together. They'd have their arguments but they would always resolve them, and Archer hated to think what they'd do after. He still put on a front for Addison, making her believe that he liked Derek, but he was starting to think that she could see through his front and knew better. Addison knew her brother too well and Archer was sure that she was just playing along for his sake. Derek on the other hand had begun to show how much he hated Archer and Archer could see how uncomfortable Addison felt when they were both around and Derek was in a foul mood.

For a whole year Archer was satisfied that Derek wasn't hurting Addison, but then he began to see a change in Addison and he instantly knew that it was Derek. He had questioned Addison a few times but every time she had insisted that she was fine, that her and Derek were fine. Archer knew better though, and he watched them closely, trying to make Addison smile whenever he saw her.

Archer had tried his best for six months to get Addison to open up to him before one night she broke down and sobbed to him, telling him how Derek had become absent and Archer had comforted her for the night, waiting until she had fallen asleep before going to find Derek and punching him, only to receive a punch back from Derek, before their fight started and Addison was clearly pissed at both of them and refused to talk to Archer for a whole week. Archer knew she had a right to but he was angry that she was still talking to Derek, if she got to see him that was. Archer knew that Derek wasn't the one for her and he just wished she could see it as well.
