"Tell me why I'm going again?" Callie asked as she leaned against the doorway of Addison's room.

"Because, I don't want to go to Seattle alone" Addison called out from her closet. She walked back in with a handful of stilettos, in every color.

"Scaredy Cat. You and Derek have been together for a few months, you should be fine by yourself, I would probably be a third wheel anyway." Callie said as she plopped down on Addison's bed.

"I am not a scaredy cat! I just...I don't want it to be weird" Addison admitted softly.

"Why in the hell would it be weird? Your dating him." Callie looked to Addison who just stood silently.

"We haven't...you know...it" Callie looked at her confused, it took her a few moments to finally get what Addison was trying to say and she gasped.

"What!? You didn't sleep with him yet?! Why not?" Addison looked up at the ceiling and took a deep breath.

"Long distant relationships don't always work out, so...I didn't want to give up my...cookies and have him break up with me" Callie burst out laughing at the term that Addison used. Addison glared at her and grabbed a pillow and hit her with it. Before she could hit her again, Callie grabbed the pillow and tried to calm herself.

"Okay! So I'm going with you for...what exactly?"

"Your coming because if things get weird, you can use your feisty personality and sarcastic ass to lessen the tension" Addison as she laughed. It was Callie's turn to hit Addison with a pillow. It soon turned into a pillow fight that left them in a haven of feathers. They were both rolling on the floor, howling with laughter and tears streaming down their faces.

"Fine! You win! I'll go with you, you pain in the ass!" Callie shouted as she stood up and Addison hopped on her back and sent them both falling to the ground. Addison leaned over and gave Callie a loud kiss on her cheek, Callie shook Addison off her back, hitting her head on the floor.

"Thank you, thank you!" Addison said, she got back to her feet and continued packing. Callie went back to her bedroom in the apartment that they shared. .

Callie and Addison have been best friends since birth. Their parents were all surgeons who worked at the same hospital, so the girls spent a lot of time together when either parent was paged in. The two girls lived next door to each other in sunny Miami, Florida. The girls were never seen apart, they went to the same schools, liked the same things, had the same friends and did the same things. They were inseparable. After high school, both Addison and Callie got into NYU where they both attended college. Both women wanted to follow in their parents footsteps and become surgeons. Callie chose Orthopedics and Addison OB-GYN. College were the best years of their lives for both women. Time at college was spent, hooking up with guys, staying up late cramming for exams and becoming closer than ever. Both girls went through their fair amount of men during their time at NYU, but neither of them found true love. Now, they were both world-class surgeons and both worked together at the same hospital, New York Presbyterian.

A couple of months ago, Addison had a conference in Seattle. There, she met a hunky Dr. Shepard, who was a neurologist at Seattle Grace Hospital. While her time there, Addison had gone out to dinner with him, had drinks and they exchanged numbers. The night before Addison was set to go back to New York, dear Dr. Shepard showed up at her hotel door with a suitcase in hand. He had informed her that he took his vacation early and was going to go back with her. When the couple returned to New York, Callie was surprise when she went to pick Addison up from the airport. Addison had introduced him as her boyfriend and Callie played the role as the best friend. When they went to dinner that night, Callie set the rules and interrogated him until no end. When she was finally satisfied, she gave her blessing and actually came to like the brown-hair, blue-eyed man. Derek had stayed a week in New York with Addison before he had to go back. At the airport, they promised to call and come back to visit, they had both agreed to try a long-distance relationship.

Every three weeks from then on, Derek would show up at their door and surprise Addison. Addison never returned to Seattle after her first time there, she just couldn't get the time to go. While in New York, Derek and Callie had become really close, each sharing one thing in common, the love they had for Addison. That love could create quite a bond between two people.

A week ago, Derek called Addison asking if she could come and visit him this time. Realizing that she had never been the one to visit him, she agreed, and promised to drag Callie along with her.

So now, the best friends found them on a round trip flight to Seattle, neither of them knowing what to expect.

"C'mon Mark! Just come with me to the airport!" Derek begged at his best friend.

"Why can't you go alone? I'm busy, there's a new nurse in town, and she's hot"

"You're seriously gonna choose a chick or your best friend? Seriously?" Derek asked as the two made their way to the Attending's locker.

"Uh, yes, you're only gonna go pick up your girlfriend anyway, your the one choosing a chick, man" Mark chuckled.

Derek looked at the man he called his best friend, "Fine, I'll pay you to go"

Mark thought for a second, then shook his head, "You by the first round of drinks and I'm game"

"Fine! We have to go, her plane lands in half an hour"

Mark was silent as he stared at the man beside him, he had a smirk on his face, "Wow, you really are whipped"

"Yes, yes I am and we haven't even -" Derek cut himself off before he said to much. He knew Mark, and if he told him, he would me mocked relentlessly.

Mark knew something was up by the tone of Derek's voice, "You haven't WHAT?"

Derek was silent and Mark caught on rather quickly, he burst into a fit of laughter and bent over for leverage.

"Are you serious!? You guys haven't had sex yet, Derek!? You really are whipped" Derek glared at Mark and smacked the back of his head.

"Shut up and change!" Derek demanded. After Mark got over his laughter, he quickly changed back into his street clothes and set off toward the airport.

On the drive Derek said, "Oh, by the way, she's bringing her friend, so behave"

"Don't I always? Besides, if her friend is anything like the way you described Addison, I don't wanna even try" Mark received another smack to the head and chuckled.

15 minutes later, they pulled into the airport parking lot and made their way to the departures.

"Are you ready?" Addison asked as she and Callie exited the plane.

"Uh, yeah, the question is, are you?"

"I am, a little nervous, but I really miss him" Callie made a gagging face and Addison hit her shoulder.

The girls got their luggage and made their way to departures. Addison scanned the crowd for Derek. A huge smile spread across her face as she spotted a familiar pair of blue eyes that have been in her dreams for the past few months.

"Oooh! There she is!" Derek announced and waved frantically at Addison. He met the girls halfway and embraced her in a big hug. Mark trailed behind him, playing something on his phone, he still hadn't looked up.

"Derek! I missed you!" Addison said as she hugged Derek.

"I missed you too, babe" Derek gave her a quick peck then turned to Callie, who had also been on her phone and had not even bothered to look up. He plucked the phone out of her hand, receiving a firm slap to his shoulder. She snatched it back and stuffed it in her pocket.

"What, you didn't miss me?" She questioned and Derek laughed and brought her into a big hug.

"How could I not miss your sarcastic ass?" he chuckled and turned to Mark.

"Ladies, this is my best friend, Mark Sloan, Mark, this is Addison Forbes Montgomery and her best friend Callie Torres" When Mark didn't look up, Derek nudged him in his leg and sent a glare his way. Mark finally looked up from his phone and was stunned at the sight he saw. There standing before him was a very beautiful red-head, but it was the woman behind her that caught his eye. She was hot, she had curves that seemed too dangerous, her black locks hung low on her shoulders, her eyes were a dark shade of brown that seemed to pull him in further. When she flashed him a smile, his knees almost gave out on him. When he finally realized that he hadn't said anything yet, he stuck out his and flashed them his famous smile.

"It's nice to meet you, ladies" He turned to Derek, "You never told me that goddesses would be in our wake" He turned back to the girls and Addison blushed and Callie just looked at him with disgust.

Mark took a step toward Callie and held out his hand, "I'm sorry, I didn't get your name, gorgeous" He placed a light kiss on Callie's hand and held it in his.

"It's Calliope, but no one calls me that, you can call me Callie" she said as she pulled her hand out of his grasp.

"A beautiful name for a beautiful woman"

"Uh, thanks" she said and took a step back from him.

Addison and Derek stood watching the scene unfold. Derek noticed the look on his best friend's face and knew that it was time to intervene.

"Well, you ladies must be starving, can we take you out for dinner?"

"Please, the plane food is always gross, even in first class" Callie answered Derek. He chuckled, grabbed both girls luggage and led Addison out toward the car.

"After you" Mark said and Callie shot him a weird look and went before him. Mark trailed behind her, taking in the way her tight jeans hugged her ass.

When they finally reached the car, Mark and Derek loaded the girls suitcases and climbed in the car. Addison sat in the front with Derek, while Mark climbed in the back and sat next to Callie. She tried to sit as far away from him as the backseat would allow, but he kept getting closer. She noticed all his features. He was handsome, and not to mention hot! But she couldn't go there.

She knew that she couldn't fall for Derek's best friend, no matter how charming.
