- Caaaaal move on, we're going to be late at work! Mark yelled after he swung the door of his best friend's flat opened.

"I'm coooming! Callie responded while trying to put on her shoes."

Sofia greeted her dad and gave him a hug. "Morning baby girl" he said and kissed her on the forehead. They made small talk until Sofia left for high school. As Mark and Callie were heading to work, Callie was trying to share with Mark her insecurities about Sofia.

Indeed she felt like for a few weeks Sofia wasn't herself anymore. And Sofia meant everything to her mom; since they were living only the two of them for seventeen years already, she cared about her daughter more than anyone else could ever care. When they talked, the younger wasn't listening. She wasn't really there. At first Callie thought that this too would pass. Mark said that she was probably heartbroken. "I could find that jackass easily and beat the-" Callie cut him off. "No Mark, I feel like it's more serious… I don't know…" her pager went off, and she simply decided to let it drop.

As Callie was scrubbing out of her third surgery of the day, she checked out her messages. A nurse had told her she had received a text from her daughter, however she had preferred to read it later, when she would be alone. She knew how fast the gossip was spreading around at Seattle Grace Mercy West Hospital, and she didn't want Sofia to take part in them by any means. The text was just saying that she felt sick so she went home at 1pm. God, why couldn't Mark take these things seriously. Callie genuinely thought he was the best dad Sofia could ever ask for, but in moments like these, she really felt like she was the only one worrying.

It was 1:30 and she was hungry. Heck, hungry was an understatement. She'd had to left without eating this morning, as Mark was more than stressed this morning. Gee, thanks Mark. As she was heading to the cafeteria, she quickly texted her daughter back asking whether she should bring her something to eat or some pills against stomach aches. After she had paid for her food, the ortho surgeon spotted a table where her friends were eating and laughing.

There were sitting a hot redhead, Dr Addison Montgomery who had been Callie's first «true» friend when they entered med school. From there, they did together, with Mark and Derek, all of their studies, internships and residencies, along with their fellowships. The group of four had studied in New York, and when Richard offered Derek the Head of the Neuro Department at SGMW, he also offered Mark the Plastic's one. They all arrived in Seattle about five years ago.

Sitting next to the OB attending, were Mark and Derek. They were cracking silly jokes and Addie couldn't help but roll her eyes. Callie took the chair in front of her best friend, they started light conversations around their meals. But the brunette wasn't hungry anymore, and couldn't help but try to find something to make her daughter feel better. Maybe I could cook her something this evening. Or, we could have a TV night in front of one of her favorite tv show.

When she came back to her senses, Addison was the only one left to the table. "What were you thinking about? Some new boo of yours?" the red head teased. As soon as her best friend looked up in her eyes, she knew this wasn't something to laugh about. And as the ortho surgeon was explaining it all to the OB, who also happened to be Sofia's godmother, she thought she'd seen someone she never would again….

Is that you?

"You seriously look like you've just seen a ghost" stated matter-of-factly Amelia to her best friend from Hopkins who had just arrived to Seattle Grace Mercy West, Arizona Robbins.

Arizona was tall, blonde, blue-eyed and occasionally the new Head of Pediatrics at Seattle Grace Mercy West. She was brought here by Amelia Shepherd who happened to be Derek's sister. They had been friends since their first day of med school, and luckily enough, they had even been taken as interns in the same hospital. So, when the peds surgeon heard about this job, she immediately jumped on the occasion. She was going to make this program one of the best Peds program of the country.

"Zona? Are you even listening to me?" the neuro surgeon teased. "I know my brother is as close as perfect as human can be, but aren't you into girls?" Amelia stated while taking a sip of her soda.

"I am, I am. Who… Who's sitting with him?" the blonde dared to ask. She couldn't stop staring at her. Is that really her tho? I… I've carefully never read any of the med articles, except some of those that involve pediatrics, you know, because I want to be the best in what I do, but…Calliope? Yeah, she definitely never would have been a peds surgeon. So I never really knew that she was…a surgeon. I've sure seen articles signed Dr Torres, M.D but I mean, there must be tons of Torres in the country…isn't there? Her mind was a mess.

"Sooo… the hot man sitting across my brother is Mark Sloan. Hot, self confident, manwhore from what the nurses say, Head of Plastics. He probably hooked up with most of the hospital females. Even with meeeh…" at this, the blonde's face turned back to the brunette. She wasn't shocked, she was more than that! « What? His Sloan Method is really amazing! Anyway. » seeing her friend's facial expression, she preferred to just skip this part. "Then the read head is Addison Montgomery. She's always been stuck between Mark and Derek. Addie's the best OB/GYN on the West Coast. Always classy." That she could say. "And the brunette is Callie Torres. Ortho god, they call her. She'd deserve the Head of Ortho but…Chang is a dinosaur who doesn't want to quit. The four of them are inseparable since med school. I still remember this time Derek entered…"

At this, Arizona was lost in her thoughts. She simply couldn't believe it. Her Callie was here, in the same freaking hospital. Not mine anymore. She took a glance at the hot goddess across the room. She didn't know how long she stared until she saw her brother sitting next to Amy.

"Lil sis, how are you doing? I gotta say, our first day is pretty amazing. People here are so, so nice. And there are a bunch of hot women tho!" he started laughing along with Amelia. "Your sister seems almost depressed. Like, she just stared the front door for ten minutes." The brunette's arm got slapped by the blonde. "Shut up, that's not true." Although it was too true…

Timothy's first morning had been nothing but boring. He was a trauma surgeon because he wanted action, and doing rounds and charts wasn't any action. So, when his first page of the day was a 911, he couldn't help but smile and run to the ER.

As he was heading toward them, he greeted some nurses and fellow doctors. This place was nice, and he truly thought they could be happy here. Like, he and his sister could find someone and live a peaceful nice.

If I knew that someday, I'd want to live « peacefully ». he thought to himself.

He was picking out a trauma yellow scrub when he noticed waiting outside someone he hadn't seen in years. Callie Torres.

Since her lunch, Callie's stomach was in knots. Is that really her? I mean, I don't know. She's changed so much. She isn't any punk fan anymore, I bet. I know she's one of the best Pediatrician from one of the best Peds program in the country, but… it might not be her, right?

She quickly went to her place and checked in on her daughter. It was supposed to calm her down, however it didn't. She made her a quick chicken soup and forced her to eat, then headed straight back to work. She was lucky enough that her pager didn't go off until she'd stepped back in the hospital.

She was waiting in her yellow - and ugly, if she said so herself - trauma gown when she heard someone calling her.

"Kaleidopy! Is that really you?"

Callie's head snapped back at him. She was expecting to meet her sister, but not him. As he opened wild his arms, they hugged and started talking."T! If I knew I'd see you again here." Callie was so happy to run into her old friend. Like the good old times.

But just as they opened their mouth, the paramedic flushed in and started her recite. "Female, 42, european…" and they had to call off their conversation.

Finally, at past 8pm, Mark saw Callie appearing in the lobby of the hospital. As she started apologizing, she recognized someone from her past she knew so, so well. And they were talking with Addison; ouch. Daddy's mad…

"Why you like, never told me about them?" Mark snapped at her. He seemed really pissed. She didn't know what to say…. they were neighbors? friends? best friends? her first lover? girlfriend? Ugh, too complicated.

"I… I don't know! It's not like I was seeing them without you knowing. I mean… ugh, I was surprised too to see them at lunch, Mark!" Callie tried to explain. "Wait… are you jealous or something?" She couldn't believe it. Mark was being jealous! It wasn't like they were in any sort of relationship. Except co-parenting, that they pretty rocked if they'd say so themselves.

"What? No I'm not! I just thought that the mother of my child would tell me when such things happen, as her best friend coming into our hospital! For good." The tall man finished in a whisper. Oh yeah, definitely jealous. Callie couldn't hold in her laughter anymore. "Stop being such a kid, Daddy!" Mark tried to hold her by the arm as she walked toward Addison, but she simply smacked his hand.

"Joe's everyone?" Derek proposed. As they all agreed but Mark and Callie, Timothy simply asked: "Who's Joe? Is he like, another surgeon or something?" Everyone laughed and explained to him that Joe was in fact the bartender from The Esmeralda City Bar across the street. Callie couldn't help but wondered where was Arizona. Would she come?

"Hmm… Tim. You- you should come. You know, one day, come over and we could catch up!" Callie directly proposed to the young man. « Tell Az she can come too, o-of course.. » the words came out so fast she hadn't even thought about them. The beginning looked like she was bold and self-confident but actually, she wasn't. Shit. Why did you tell this Callie?

"Yes! I'm sure she'll be really happy to come too!" Tim answered sincerely. "Wait, you two don't come drink something tonight?" seeing their face, he tried to convince them to stay. "Come on, just one drink or two! For your old friend, Cal!"

"I'm sorry, Sofia's waiting for us at home… Another night, maybe?" the woman tried to apologize. "Addie will give you my phone number so… just text me some time this week?" After a goodbye hug, and a promise to catch up really soon, Callie exited the hospital with Mark.

As soon as they were out of sight, Tim couldn't help but ask who was Sofia. So Addison, realizing everyone was waiting for her to explain Callie's situation to her friend, sighed and tried her best to do so. "Sofia's their daughter. She… uhh she was feeling sick today so Callie made Mark promise to stop by her place tonight!" She finished on a smile, obviously forced.

"Thank god! I thought Sofia was her wife, seriously." He laughed at his saying. "Wait, does that mean Mark's her husband? Or boyfriend? And… How old is Sofia?" He asked, suddenly sensing that this was probably why neither of them was speaking anymore.

"No! no no no, nothing like that. They never were really together… It just, well, they slept together once and…" Addison went red, she didn't know what to tell to the man. He was way too curious. "Ugh, you know what? She'll explain everything to you herself!"
