"Remind me never to fly coach ever again." Addison Montgomery waited impatiently for her hastily packed luggage to pass by on the carousel.

Standing beside her was Dr. Amelia Shepherd, who couldn't resist the urge to smirk at her former sister-in-law's misfortune. "Just because you have a Black Card, that doesn't mean you get have your way all the time."

"Shut up."

"Serves you right anyway. I was flying up here to see Derek and you decide to tag along at the last minute."

"I'm not here to see your brother. Ah, here we go." Addison grabbed hold of her suitcase as it rotated towards her. "I used to live here too, remember? I still have friends in Seattle. Besides, you're not here to visit Derek. You just want to rub the fact that you managed to pull off an impossible surgery in his face, which you got lucky on by the way."

"Oh, so we're going there, huh?" The husky voice brunette parked her hand upon her hip. "You're not just here 'visiting a friend.'" Amelia taunted Addison with air quotes. "You're hiding. From Sam. From Pete. From Naomi. You ran out of town with your tail tucked between your legs."

"Air quotes? Seriously?" Addison walked away, dragging her suitcase behind her. Amelia huffed in disbelief and followed along with her own suitcase.

"Okay, maybe I was a little out of line back there..."

"Uh, ya think?" Dr. Montgomery didn't even bother looking at who was speaking to her.

"...but honestly, Addison, I'm worried about you. You're not you these days. Yeah, you're still a kick ass surgeon. Shit, you made me look good. However, when it comes to your love life..."

"I think you've made it abundantly clear what you think about my love life. On more than one occasion." The fiery redhead finally made eye contact with Amelia again. "And for future reference, next time you have an opinion, do us both a favor and keep it to yourself."

"I'm sorry, Addison. I have a tendency to speak without thinking..."

"Yeah, I kinda picked up on that."

"...but I care about you. I still love you like family. It just hurts my heart to see you this way."

"I appreciate your concern, Amy..."

"Amelia."

"...excuse me, Amelia. But don't waste your time worrying about me. I'm fine."

The young neuro surgeon knew that Addison was lying to herself.

Awaiting Addison's arrival at Seattle-Tacoma International Airport, Callie Torres was filled with conflicting emotions. She was elated that one of her dearest friends decided to visit. At the same time, she worried about the future of her relationship with Arizona. It took a lot of effort to avoid the bubbly peds surgeon, a task made easier by Arizona herself. The couple was going strong, existing in a state of pure bliss. Certainly, they've had their disagreements. Yet, they always managed to resolve their issues. Arizona recently put the breaks on the relationship, feeling the need for some space. Her girlfriend not wanting kids left Callie wondering if they should break up. Splitting apart would be the easy route. She'd still want to know why someone so good with children didn't want any of her own. Torres sorted through all the moments she brought up the topic, and they all had one thing in common. She remembered the fear in Arizona's eyes. Oddly enough, it gave her hope. It meant that maybe it was something left worth fighting for.

Out the corner of her eye, Callie noticed someone approaching. She glanced over to her right, and returned her attention to what was ahead of her. The dark haired man looked vaguely family, but he was too far to make out who he was. A second glance confirmed that he was in fact someone she knew. Perfectly coiffed brown hair, with a slight streak of grey in the front. Well dressed with an old school movie star swagger. His name, Derek Shepherd; the newly appointed Chief of Surgery at Seattle Grace-Mercy West.

"Good afternoon, Dr. Torres."

"Hmph." Callie immediately chuckled. "Do we have to be so formal outside of work?"

"Uh, no. I suppose not." Torres almost swore she noticed a twinkle in his eye when he laughed. "So, Callie, you've got family flying in?"

"Nope, not this time. Addison's coming to visit."

"Really? Nobody called her for consult. At least not that I know of."

"I'm just as surprised as you are. She just called me last night out of the blue and asked me if could I pick her up from here. I was thinking the same thing, maybe she was flying in for a consult. But, no. She's just visiting. So, who are you here to pick up?"

"My sister, Amelia. She's also a neuro surgeon." Derek was beaming with pride that one of siblings followed in his footsteps. "As matter of fact, there she is now...with Addison."

Callie turned towards the two women approaching them and immediately smiled. Addison smiled in return, her vividly auburn locks slightly longer and fuller than the last time she was in Seattle. She towered over a petite brunette walking beside her. When it came to the Shepherds, good hair apparently ran in the family.

Callie walked towards Addison, who paused to give her good friend a warm embrace. Amelia arched up to peck her brother on the cheek before giving him a hug. Addison and Derek greeted each other with a nod and slight smile.

"Amy," Derek gestured at Callie. "This is Dr. Torres, one of my attendings at the hospital."

"Again with the formalities, huh?" The raven haired beauty extended her hand towards the younger Shepherd. "Hi. You can call me Callie."

"Nice to meet you." The fellow surgeons shook hands. "Hmm. That's quite a grip you got there, Callie. Let me guess. Ortho, right?"

"Yeah. How could you tell?"

"Aw, cut it out." Addison slightly tapped Amelia with the back of her hand. "I told her about you on the plane. Such a show off."

"She hasn't changed much, hasn't she?" Derek chuckled as Amelia nudged his arm with her elbow before settling into another hug. "You're staying at the Archfield, Addison?"

"Do you even have to ask?" The fiery redhead responded with a smirk. "I bet Amelia will fit right in at the frat house you call a home."

"Things have calmed down a bit. It's just me and Meredith. And Lexie. And Alex."

"Alex? I thought him and Izzie moved out after they got married..."

Derek shook his head, immediately silencing his ex-wife.

"I'll tell you all about it later." Callie rested her hand on Addison's shoulder.

"Wow. And I thought there was drama at your job, Addison." Montgomery starred daggers at the scrappy young brunette.

"Come on, Amy." Derek smirked as he grasped the handle of his sister's suitcase. "Let's get you back to the frat house. I'll see you two later."

Addison and Callie waved goodbye to the Shepherds.

"Little sisters can be the worst, can they?" Callie locked arms with Addison before they began walking towards the exit.

"I wouldn't know anything about that. I am the little sister."

"Ouch. Open mouth. Insert foot."

"It's okay." Addison gave Callie a friendly nudge with her shoulder. "I'm pretty sure Archer has plenty of stories of how irritating I was when we were younger."

Callie responded with a smile.

Shortly after walking into the short term parking lot, Addison's eyes lit up at a familiar sight.

"Aww. You're still driving the Thunderbird."

"Yep, that's my girl." Callie patted the roof of the vintage vehicle she restored herself and opened the passenger door for Addison. The ortho surgeon took over the handle to Addison's suitcase and dragged it to the rear of the Thunderbird, placing it gently inside the trunk. Addison reached over and unlocked the door for her friend, which Callie thanked her for.

"So, how's your other girl? Y'know, the peds surgeon."

Torres' silence was an indication of things were going with Arizona. Addison caressed her shoulder, hoping it would ease her nerves.

"We're sort of on a break." Callie's gaze was fixated on the steering wheel. "I was cooking us dinner and she came over. She told me she wasn't staying... "

When Torres' voice cracked, Addison put her arm around her friend's shoulder and leaned over to peck her on the side of her forehead.

Callie cleared her throat.

"...she told me she wasn't staying." The ortho surgeon's voice was back to full strength. "She was there to pick up some of her things and to tell me that she needed some space."

"You think you'll be able to work things out?"

"She's scared, Addison. She's scared and it hurts me that she doesn't want to talk about it."

"I tell you what." The former Mrs. Shepherd took hold of Callie's hand. "Come crash with me at the Archfield. We'll order room service. We'll make it a girl's night. Just the two of us. We'll be like...Thelma and Louise."

"Uh, Addison. I love you, but I am not driving over a cliff for you. No freakin' way. I worked too hard on this car."

Addison was happy that she was able to bring a smile back to Callie's face.

"Is she alright?" Lexie Grey observed Arizona walking back and forth in the hallway, lost in her thoughts.

"Dude, she's seriously tweaking right now." Alex Karev stood beside his roommate as she watched his mentor. "Why else would she be pacing in front of Dr. Wyatt's office?"

"Dude, I can hear you." The peds surgeon pulled herself out of her funk to admonish her new student. "Both of you."

Little Grey immediately turned and walked around the corner to the adjacent hallway. Karev quickly followed suit. The agitated glare from Dr. Robbins reminded him of when she threatened to hit him with a brick.

"You so need to work on your whispering skills, Alex."

"Shut up. She heard the both of us, remember?"

Arizona was about to resume pacing when Dr's. Owen Hunt and Cristina Yang emerged from the psychiatrist's office. The trauma surgeon greeted Robbins with a nod, while his girlfriend barely acknowledged the peds surgeon. There was some lingering tension between them from the time Yang brown nosed Robbins to get on her service, yet they tolerated each other because of their connection with Callie. Since Arizona told her girlfriend she needed some space, Cristina no longer saw the need to be cordial.

"Dr. Robbins," Katharine Wyatt's voice immediately commanded her attention. "Did you need anything?"

"Oh...uh, no. No, thank you. I was just...I was just passing through and..."

"I see." The psychiatrist wasn't convinced. "Well, if you ever need to talk, I'm here."

The peds surgeon quickly walked away, heading towards the lobby. As she briskly walked out of the front entrance, Dr's. Teddy Altman and Mark Sloan were making their way towards the hospital. The two surgeons had recently been enjoying other's company after being fixed up by their mutual friends, Callie and Arizona. Sloan was making a noble effort to get better acquainted with the new cardiothoracic attending even though she secretly harbored feelings for Owen Hunt. Yet, she decided to take a chance on the cocky plastic surgeon to at least see where it would lead her.

"Is that Arizona? Where's she off to in such a hurry?" Teddy's voice was weighed down with concern for her new found friend.

"Aw, who cares." Sloan made no effort to hide the disdain in his gruff voice.

"What's eating you?"

"She hurt my best friend."

"That's really sweet that you're concerned about Callie, but Arizona didn't break up with her. She just asked for some space."

"Don't take her side."

"I'm not taking her side. But maybe she has a good reason for wanting to slow things down for awhile."

"I doubt it."

"Look, I haven't known her that long. But, Arizona doesn't strike me as someone who just does things on a whim. I'm going to go check on her. I'll catch up with you later."

Mark simply huffed in response.

"Don't be mad." Teddy drew herself closer to Sloan. Initially, he resisted but then took her into his arms. "She's my friend. I have to check on her, okay?"

"Alright."

The two surgeons briefly kissed. As Teddy walked towards the side of the hospital, she turned and smiled at Mark, who stood exactly where she left him. Arms folded together, his lips slowly curled upward into a smile of his own. Dr. Altman was shocked to find the peds surgeon taking a drag off of a cigarette. Once their eyes met, Arizona quickly stubbed out the cancer stick, exhaling a plume of smoke.

"Too late. I already saw you."

"I only smoke when I'm having trouble with Callie, which is thankfully not that often. But, this is the most I ever smoked in a long time. I'm already on my second pack this week, and it's only Monday."

"That's not good. Not good at all. And I'm not speaking as a cardiothoracic surgeon, but as a concerned friend. So, what's the deal? You never told me why you felt that you needed some space from her."

Arizona broke eye contact from Teddy, looking downward instead. She wanted to tell her why she decided to take some time apart from her beloved Calliope, yet couldn't string the words together.

"Sweetie, I'm not going to press the issue. But you really need to talk about this. If not to me, then somebody. Not only are you hurting Callie, you're hurting yourself. And at the rate you're going, you're going to end up on an iron lung before the week is out."

The peds surgeon mulled over the advice from her newfound friend. She looked towards Teddy. "I'll try."

"There is no try," Dr. Altman placed a hand on Dr. Robbins' shoulder. "Only do."

Arizona's brow quickly furrowed. "Did you just quote Star Trek to me?"

"Not exactly." Teddy patted her friend on the shoulder before stepping away. "I kind of borrowed it from Star Wars."

The peds surgeon gave her colleague a puzzled look.

"What?" Teddy shrugged her shoulders. "Mark's got me watching those movies and I actually kind of like them. So, sue me. Listen, I'll catch up with you later, okay?"

"Alright."

Teddy waved goodbye before walking towards the front of the hospital. Arizona waited until she was completely out her line of sight before pulling out another cigarette. She held it in between her lips, but couldn't bring herself to light it. After a moment, the peds surgeon removed the cigarette from her mouth and tossed it into the nearby garbage can, along with a book of matches and a nearly full pack of Virginia Slims.
