Thank you for the reviews and follows/favorites! I love to hear what people think of this story!

The next few days went by in a whirlwind. Addison was cleared to resume surgery and slowly started back. It felt great to be back in the OR!

On Saturday, Mark was planning on coming over around noon. Derek and Addison decided to spend the morning being lazy.

"Derek, "Addison said cuddling up to her Love. "I want to build a house on this land." Derek rolled her over and leaned up on his elbow so he could see her.

"Does this mean you want to stay here permanently?" he asked excitedly. He had hoped Addison would want to leave NY, but knew it was a long shot.

"I do." she smiled. "I want to keep our home in the Hamptons for vacations, but I don't really see a reason to keep the Brownstone."

"I agree. That house doesn't really fit us anymore. We have both changed a lot in the last few years."

"There is another thing." Addison said, nervously playing with her hair. "I want to have a baby." Derek immediately scooped her in her arms and gave her a tight hug. He then leaned in and kissed her deeply.

"Addison, I would love to have a baby with you. Why don't we start trying now?" Derek chuckled.

"Sounds good to me." Addison smiled.

A few hours later, Mark pulled up to find Derek grilling steaks outside while Addison laid in a hammock reading. He got out of his car with his mouth wide open.

"You two seriously have been living in this?!" he exclaimed walking up to the trailer.

"Hello, Mark." Derek said chuckling. "And yes, we have. It has been great!"

"Great may be a little extreme, Derek." Addison said getting up from the hammock and closing her book. "I'd say more like cozy. Yes, that is the right word." She walked over and gave Mark a quick hug. Mark shook his head in disbelief. Had Addison Shepherd just called a trailer cozy? Things really had changed.

"So, can I see the inside of this cozy place?" Mark joked. "It should take a total of 5 minutes."

"Sure, but after lunch, we can show you the place where we are going to build our new house." Addison said casually. Mark stopped in his tracks and looked back and forth between Derek and Addison.

"Does this mean what I think it means?" Mark asked.

"It means we have agreed to make Seattle our permanent place of residence." Derek said walking over and wrapping his arms around Addison. "It was Addie's idea, actually."

Addison leaned back in to Derek and smiled. It was a beautiful summer day, she was in the arms of her soulmate, and their best friend was with them. She hadn't been this happy in a long, long time.

"Wow." Mark said slowly. "You guys really have changed. I knew you seemed different at the hospital. I just didn't realize how much you have grown! I guess that means I am moving to Seattle!" Mark couldn't stop grinning. Addison walked over and gave him a big hug.

"Welcome to the wettest city in America!" Addison laughed.

"As long as the 3 Muskateers stay together, I can handle a little rain." Mark joked. Addison and Derek laughed as they all remembered Halloween during their last year of Med school.

Addison sat at the apartment curled up, surrounded by books. There was a nasty storm brewing outside, so she was studying indoors. She had a major test in a few days that involved that many different parts of the brain and their function. It confused her so much and couldn't understand how Derek had almost all of it memorized already! While she was studying, Derek and Mark walked in laughing. They were soaking wet from the rain.

"Hey Babe! How's it going?" Derek asked as he walked over to Addison, giving her a kiss.

"Ugh, not good! I can't remember any of this stuff!" Addison in exacerbation.

"Oh, you'll be fine! You always say that before a big test and then you get the highest grade!" Mark teased. He walked to the fridge and got a soda. "So, are you guys ready for the Halloween party tonight?" Addison put her head in her hands. She totally forgot about the party.

"I can't believe you guys talked me into dressing up as the 3 Muskateers! Bizzy would faint if she saw me!" Addison exclaimed.

"That was why you agreed to it." Derek laughed. "Because you knew Bizzy would hate it." Addison smirked at this. It was true. She wanted to be the complete opposite of Bizzy.

"Alright fine! I will go for a little bit, but you have to let me study until then. Now both of you out!" Addison said sternly.

"Yes, mam!" both boys said, saluting her as they left the room. Addison rolled her eyes. Those two would never grow up!

A few hours later, Addison, Mark, and Derek arrived at their friend Ashley's house for the party. Addison knew that Mark liked Ashley and wanted to impress her tonight. The night started off like any other party. They had fun dancing, joking around, and drinking. Addison laughed as she watched Derak and Mark try to hold their liquor, but it never failed. They always got tipsy before her. She swore as a Montgomery, alcohol ran in her veins.

Derek walked over to Addison and wrapped his arms around her. "You are the most beautiful Musketeer ever!" He slurred, kissing her on the cheek. Addison smiled. She loved how affectionate Derek was.

"Where is Mark? I haven't seen him in awhile." Addison asked.

"It's Mark. Do you even need to ask?" Derek chuckled. "Ashley has been missing for awhile, too." Addison groaned. Mark was always sneaking off at parties to go have sex. All of the sudden, there was a loud boom and all the power went out. Addison grabbed Derek instinctively. He wrapped her in his arms.

"It's ok. Looks like the storm took out the power. You stay here on the couch, and I will go find Mark. It is about time to head home anyway."

"No, Derek. You can barely walk. YOU stay on the couch, and I will go find Mark!" Addison commanded. Derek started to protest, but Addison wouldn't listen. She forced him to sit down. She knew he would be mad, but also knew that it was the best option.

Addison felt her way through the dark house looking for Mark. Eventually she found him passed out in Ashley's bed, completely naked.

"Great!" Addison thought. "Derek can barely walk, Mark is passed out, and it is pouring down rain, and we have to walk 5 blocks back to the apartment. This should be fun!"

"Mark! Wake up! It is time to go home!" Addison said poking him. She was able to rouse him enough for him to get up and get some clothes on.

"Hey Red! What's up?" Mark asked as he stumbled out of the bed.

"It is time to go. Meet Derek and I in the living room once you are halfway decent." .

Addison still couldn't believe she had managed to get all 3 of them home that night without any injuries. Albeit, they were covered in mud from multiple falls and their costumes were completely ruined. But it had been one of the few times Addison had actually had fun in the rain.

"Well, there better not be anymore drunken escapades out of you two like that! I am too old to half carry your asses home!" Addison teased.

The three friends enjoyed lunch on the front porch, reminiscing about old times. When they were done, Derek quickly showed Mark the inside of the trailer.

"Now to show you why I bought this property." Derek exclaimed as they came out the front door. "Would you like to drive one of the quads?" Derek asked heading to the back of the trailer. "Addison and I can share one."

"Dude! I have been here for an hour and you are just now telling me you have quads?! The two best friends used to ride 4-wheelers all the time as kids. "We have GOT to take a trip to the Oregon coast and go ride on the dunes! I hear it is amazing! You wouldn't even have to pack. Just hook your trailer up and you're ready to go!" Mark laughed.

"Very funny!" Derek mocked, punching Mark in the arm.

"Actually, Derek. I am a little tired." Addison said. "Why don't the two of you drive up to where the house will be so I can take a nap."

Derek walked over to Addison in concern. "Are you sure, Babe? You ok?"

"I'm fine. Just a little tired." She replied, giving Derek a hug. "You know because of the escapades this morning." Addison whispered in his ear causing Derek to smile.

"Alright you two. I have known you long enough to know what you are talking about. Addison is tired from sex this morning. Great. Now can we go, Derek?" Mark said pulling his best friend away.

Addison chuckled as she saw the two men put their helmets on and drive off. It was so good to see them as friends again. She knew Derek would not only show Mark where the house was, but he would also show him the trails through the woods he had created for the quads.

She walked in to the trailer and started washing the dishes when a wave of nausea hit her. Addison grabbed the counter and took a deep breath. She couldn't be getting sick. She had too much to do at the hospital. After a second, it passed and she was able to finish the dishes. She then walked over to the bed and climbed in. It took a bit to get comfortable, but eventually she did and fell asleep.

Meanwhile, Derek and Mark were having a blast riding the quads. Mark showed him one of his favorite trails around the lake. It led them to the place where they would begin building their house in the spring.

"Dang, Derek! This view is amazing!" Mark said, pulling off his helmet. The afternoon sun glistened off the lake, and the mountains seemed to go on forever. "I could get used to this!"

"I know! Now you see why I am glad Addison decided to stay!" Derek replied. He walked over to the dock in the lake and sat down. After taking his flip flops off, he dangled his feet in the water and sighed. "This really is heaven on earth."

Mark followed him, and he too removed his shoes and dangled his feet in the water. "This reminds me of lazy summer days out on your grandpa's farm!" Mark said with his eyes closed.

27 years ago

10 year olds Derek and Mark were bouncing around in the backseat of the Shepherd's station wagon. They had been driving for almost 15hours on their way to Grandma and Grandpa Shepherd's farm in Indiana. They were so excited that Mark got to stay on the farm for 3 weeks with Derek this year. It was an annual tradition in the Shepherd house. All children over the age of 7 got to go. Derek always came home raving about how awesome the farm was, which made Mark very jealous. He finally got to go this year!

As they pulled up on the farm, Mark couldn't believe how much corn there was everywhere! He actually saw someone driving a riding lawn mower through a McDonald's drive-thru! He felt like he was in a foreign country.

As soon as the car stopped, Derek jumped out and ran straight for the barn. Mark knew exactly what he was going for….the barn swing he had heard so much about. Mark ran after him.

"Derek! Derek!" Christopher Shepherd yelled after them shaking his head. "Sorry, Mom and Dad." He said hugging his parents. "He should at least say hi before he goes running off!"

"Oh, Christopher! Boys need room to run and play! Let them be." Grandma Shepherd exclaimed. "Besides, I have two other grandchildren to love on! Hello girls!" She said hugging Nancy and Kathleen.

"Hello, Grandma!" the girls said in unison, hugging their grandparents. They were not as excited to be here as the boys. At 12 and 14, they were more interested in staying home so they could see their friends.

The next few weeks went by way too quickly for Derek and Mark. They swam in the pond, played outside in several thunderstorms, climbed trees, and of course, swung on the barn swing. Mark's favorite part of the trip was when they caught a snake and scared the girls with it!

Derek smiled. "We really did have some good times on that old farm! I think that is another reason I fell in love with this land. I would for my kids to be able to grow up with that."

Mark opened his eyes and looked over at Derek. "Kids? Are you guys talking about having kids?". He was a little shocked by this.

"Uh, yeah, well, we've talked about it. No set plans or anything yet." Derek stammered. He wasn't quite sure he was ready to talk about this with anyone but Addison.

"You know, " Derek said changing the subject. "We own over 40 acres. I could sell you a couple if you wanted to build a house out here."

"Seriously?" Mark asked surprised. "You want me living that close to you!"

"Yes, I really do. I've missed you, man." Derek replied. "Look, a lot of shit has happened over the last few years. All 3 of us played a part in it. I don't want to go back. I want to move forward. Addison and I have changed so much, and I am pretty sure you have too. I want to move forward with a new and improved life. I would love to have someone to ride quads with, go fishing with, etc. Addison hasn't changed THAT much." Dere said, causing both of them to laugh.

"I'll think about it." Mark answered standing up. "It really is pretty out here. I need to get going though. I have a hot date tonight with some Lexie girl."

Derek stood up and just stared at Mark. "Lexie, as the Lexie Grey, the intern?" Derek asked shaking his head.

"Yes, is that a problem?" Mark asked confused.

"That is Meredith Grey's little sister." Derek explained. "Be nice to her, Mark. I have already hurt the Grey family enough. You don't need to mess around with her and then not call her back."

"This may surprise you, Derek, but I don't really do that anymore." Mark said while Derek gave him a skeptical look. "But, if it makes you feel any better, I will be nothing but a gentlemen."

Derek walked back over to the quads and said through his helmet, "Just keep little Sloan out of little Grey." He then sped off before he could hear Mark's response.

"Little! Little, my ass!" Mark sputtered before taking after Derek.

A few hours later, Addison awoke to a kiss. When she opened her eyes, she saw a pair of ocean blue eyes looking at her with concern.

"Are you sure you are ok, Addie? I thought you just didn't want to come with us earlier and were joking about being tired. You rarely take naps." Derek asked with concern. He started to feel her forehead.

"I am not sure, honestly. I wasn't planning on sleeping this long, and earlier I started to feel nauseous. I seriously hope I am not getting sick!" Addison complained. She had a bit of a headache and didn't want to get out of the bed.

"Would you like me to make you some hot tea?" Derek asked, getting up.

"Sure, Babe. That would be great." Addison smiled weakly.

As Derek was bringing Addison some tea, his pager went off. "Ugh, Looks like I am going to have to go into the hospital. Will you be ok here?"

"Derek, I am a grown woman and a doctor. I think I will be ok for a few hours by myself." Addison chuckled.

"Yes, dear." Derek smiled back. He gave Addison a kiss and then left for the hospital.

While Derek was gone, Addison decided to call her best friend. "Savvy!" Addison exclaimed when she answered.

"Addie! How are you?" Savvy asked. She hadn't spoken with Addison since she had left NY. Life with a toddler had kept her so busy!

"I am doing well. I have been fully back a work for a bit now. It feels so good to be in the OR again!" As the two continued to talk, Addison mentioned that she had been really tired lately and not feeling the best.

"Addison, have your boobs been hurting?" Savvy asked out of the blue.

"WHAT?" Addison exclaimed shocked. "Did you really just ask…?" All of the sudden a light bulb went off in her head. She said straight up in bed.

"Are you trying to ask if I am pregnant?!" she nearly shouted.

"Well, are you?" Savvy asked slyly.

"There is no way!" Addison said slowly.

"Oh, really. So you and Derek haven't been going at it a lot lately?" Savvy laughed out loud when only silence answered her.

"Savvy! How did I not even THINK of that as a possibility?!" Addison groaned, pacing the trailer. Sure she wanted to have kids with Derek. But, NOW! She was a planner. This wasn't planned.

"Addie, calm down!" Savvy yelled, jolting Addison back to the conversation. "You don't even know if you ARE pregnant! You need to calm down until you know for sure."

Addison knew she was right, but she had also been around enough pregnant women to know that all the signs were pointing to one thing….being pregnant. She had to find out.

"Savvy, I hate to run. But I need to find out, TODAY, if I am pregnant. I will call you as soon as I know anything" Addison hung up the phone before Savvy could respond, grabbed her keys, and drove to the hospital.

When Addison arrived at the hospital, she knew she did NOT want to see Derek. She didn't want him to get excited if there was nothing to get excited about. She snuck in a side door and went straight to the maternity floor. Addison found an empty exam room, locked the door, and drew some of her blood. Giving herself an IV was not easy, but there was no way she would chance getting rumors spread by getting anyone else involved.

Once she had the blood, Addison took the blood to the lab under a false name.

"I need this back ASAP." Addison told the tech. "Page me directly! No one else"

"Sure, Dr. Shepherd." the tech replied. He was used to the attendings demanding the tests be done ASAP.

Even though Addison wanted to tests back right then, she knew it would be a few hours. She decided to go find Derek. She first went to check the OR board, but his name wasn't there. Then she went to his office. It too was locked with no lights on. Where in the world was he? He wasn't answering his phone either.

Addison asked the nurses' station if they knew where Derek was. No one had seen him and knew about a page that day. Now Addison was thoroughly confused.

After looking around the whole hospital with no success, Addison decided to head to her office to wait for the test results. As she was getting some paperwork done, she got a text from Derek that said "This case is taking longer than I thought. I won't be home until late. Don't wait up. Love you!"

Addison just stared at her phone. What case? It obviously wasn't one at the hospital. Before she could respond to the text, Addison got a page saying her test results were ready. Addison went down to the labs, picked up the results, and headed back to her office.

She was almost terrified to read the results. Slowly, she opened the envelope. There, in plain black and white, was the final proof she needed that she was pregnant. Her HCG levels were over 3000. Addison picked up the paper and gasped.

"No, it can't be!" Addison exclaimed jumping up. "I can't be more than 6 weeks along. If my HCG levels are that high…." She slowly sat down. "It means I am most likely having twins."

Let me know what you think!
