A/N: This is my first fanfic so please bare with me as I learn my way through the FanFiction universe. I started watching Greys last year during quarantine, then someone mentioned fanfics and I've been hooked ever since. So this story is kind of based of the S8:E13 If/Then but a totally different version. It also includes G!P. So if you're not into this I suggest you don't read it.

CALLIE POV

"Mark! Open your door!" I shout pounding on it while trying to console my three year old son.

"Aiden, calm down it's gonna be okay. Uncle Mark is gonna take you to day care."

"O-okay ma-mi." He sobbed.

Mark and I have been best friends for years. We met back in high school. He's the one who helped me figure out that I was bisexual. Then he introduced me to my first girlfriend. Then later we went off to college where we met our other best friend Addison. We all did our internship at Seattle Grace Mercy West and we all stayed here ever since. Now all three of us are the head of our own departments.

I hear Mark's booming voice come from the other side of the door. "I'm coming Torres." He swings it open. "Where's the fire?" He looks at Aiden,"Shoot I'm so sorry. I forgot I'm supposed to watch him-"

"Mark it's okay. I just need you to drop him off at the daycare before our head of department meeting today." I say as I hand him Aiden, who has calmed down.

"Sounds good Torres, I heard the new head of Peds should be here today."

"Really? It's about time."

"Yeah I heard she's the best of the best. Like she literally craps puppies. She even won a Carter Maddison, she just came back from Africa. So I'm not surprised Webber hired her first."

"Do you know her name?" I asked trying to situate all my bags on my shoulders.

"No, I haven't. The chief is keeping it on the down low."

"Okay well I need to go. Thanks again Mark." I kiss his cheek and then I kiss Aiden's cheek.

"I'll see you later tonight, okay. I love you Aiden."

"Love you to mami." Aiden smiles.

I look at Aiden with sad eyes. Mark can tell I'm feeling mommy guilt.

"Torres no.. no don't make that face. He needs to see you work. It's good for him to see you achieve. He needs to know that his mother is a badass surgeon. Then when he grows up he will be a Plastics god. Just like uncle Mark. Right buddy?" He says as he tickles Aiden.

"Plastics God? No ways he's straight Cardio."

"I don't think so Torres, with his handsome face, he will for sure bring in the ladies."

I roll my eyes at Mark. "Seriously Mark? Well I got to go. Thanks again."

"Okay, go get out of here." He says tilting his head towards the elevator.

For the past three years it's just been Aiden and I. I decided to have Aiden when I turned 30 right after I became an attending. I wasn't with anyone, but I really wanted a baby and I didn't want to wait for the right person to come along. So I asked Addison what the steps were for IVF, she helped me, then a few months later I had Aiden. Of course I've had my share of one night stands a few dates, but nothing serious. Those dates mostly ended the moment I said I had a son and that never bothered me. If they couldn't accept Aiden, then it wasn't worth my time.


I looked at my watch and I noticed I got 30 minute before our department head meeting. So I decided to fit in one more person before I head to the conference room. I'm doing my morning rounds on the Pediatric floor. When I walk up to the nurses station looking for my charts, I noticed that one was missing. "Hey Ruby, do you know where Riley's chart is?"

"No I don't Dr. Torres. Maybe Yang took it. She was here earlier. She might still have it. Also rumor has it we also got a new Peds doctor. Not just a new department head."

"Okay I'll go check in the patient's room. Thank you Ruby."

When Im almost to my patients room, I can hear Yang talking to someone about his charts. I know that Riley's parents are at work, so she can't be talking to them.

"I think you should really talk to Dr. Torres before you go looking into a patient's chart" Yang argued.

"Sorry, what's your name again?" The person says. Okay so Yang is talking to a women.

"My name is Dr. Cristina Yang."

"Okay Dr. Yang. I appreciate your input but I will not be having an intern or some cardio surgeon hacking up this kids lung and putting in an artificial lung. This procedure hasn't even been FDA approved."

"I'm a third year resident. And I'm Sorry who are you? Are you even a doctor? Yang questioned.

"Just cause I'm not using a white coat doesn't mean I'm not a doctor."

I finally decided to make my presents known as I finally walked in, having heard enough. When I walk in I'm almost speechless. This women in front of me is gorgeous. Beautiful eyes, long wavy blonde hair. So I clear my throat. "Hey, what's going on in here and why do you have my patients chart?"

"Oh so you must be Dr. Torres?" She says with an eyebrow lifted up.

"Yes I am. Now who are you?" I say crossing my arm. I didn't expect her to be so defensive.

"My name is Dr. Arizona Robbins." She says holding her hand out. I shake her hand and nod my head.

"Doctor?" I whispered. I give her a good look, she's wearing regular clothes. She doesn't even have a name tag on, but she looked familiar.

"Yes. Dr. Robbins." She speaks up.

"Okay so what are you doing with my patients chart?"

"I'm taking over this patient's case."

"Excuse me?"

Arizona nods her head as if that's a good enough answer for me.

"How about we talk about this in private? Yang I'll see you later" I offered.

"Okay Dr. Torres." Yang says flatly walking out.

"Sure, but it has to be quick. I have to be somewhere soon." Arizona says looking down at her watch.


Arizona POV

Walking into SGMW hospital, I'm met with my older brother at the door. "You loving your new loft Zona?"

"Yeah it's great." I smiled.

"It's a total smash pad. I can't imagine how many women your gonna be bringing back there. I'm sure it was torture not getting any for 3 years in Africa."

"You have no idea, but being there helped me realize something."

"Oh yeah? What's that?"

"That I'm ready to have a serious relationship. No more meaningless sex. No more one night stands. So in order to get this." I point to my lower region, "You need to get through this." I say pointing to my heart.

"Wow Africa changed you. And I'm loving this new Arizona."

"Yeah I am too."

"So you ready for your first day Zona?" He looks down at my shoes. "Please tell me you aren't wearing those heelys. Arizona you're 34 years old."

"Ready as I'll ever be. Just the jitters. Just like when we were kids, when we had to move to somewhere new. And you know better than to diss my wheely sneaks." I say shoving his shoulder.

"I know exactly what you're saying. I'm sorry about dissing the sneaks. We all know the kids love them" He laughed.

"Well I love them too. I'm not gonna lie I'm nervous about working with new people."

"Relax Zona. You're gonna love it here. Everyone is awesome at their jobs. We are kinda like a family, except everyone sleeps with everyone."

"Well you were here since your residency, so of course it feels like family. I'm new here and I'm head of my department. So I need to prove myself."

"Arizona calm down, you're the best pediatric surgeon in the country. You just came back from Africa. Your a Carter Maddison grant winner for crying out loud."

"Timothy that doesn't matter. You need to earn peoples respect. It's not just given to you. You know that."

"Okay, seriously. You need relax. Come I'll show you the chief's office."

Timothy knocks on the door, and I hear a faint "Come in."

"Hey Chief Webber. This is my sister. Dr. Arizona Robbins. Of course you know her, but I just wanted to formally introduce her to you."

"It's nice to finally meet you in person Dr. Webber and not just through a computer screen. Thank you for this opportunity, it's honor to work here sir."

"When Timothy came up to me and told me who his sister was and that she was returning home from Africa, I knew I had to do everything in my power to snag you before anyone else could. So it's an honor to have you here. If you need anything let me know."

"I will. Thank you."

"After our department meeting today. I'll have HR bring down your name tag and white coat."

"Okay, chief. I'm gonna go check out my peds wing. Get a head start on my patients and see what Dr. Stark has left me with. I'll see you in the meeting."

"See you then."

I walk out the door and Timothy follows me. "That went well don't you think?"

"Yes it did."

"I'll walk you to your office, then I'll head down to the Ortho wing."

After Timothy, left I decided to introduce myself to a few of my peds staff and patients. When I walk into Riley's room, I noticed that there was someone already inside studying his chart. She looks like an intern. So I lean over her shoulder and look down and read a few of the words on the chart. I see the word "Artificial lung" and that gets my attention. I grabbed the chart and read the course of treatment. I can hear her talking to me and then I finally look up and ask who she is. She's a little aggressive, which I can appreciate in a surgeon.

Just then a beautiful women walks in, and I mean beautiful. She's stunning and gorgeous. I remind myself to focus. "So you must be Dr. Torres?" After we introduce ourselves, I can tell she's still defensive. I'm not sure how to tell her that I'll be taking over. So I just flat out say it.

"I'll be taking over this patient's case."

"Excuse me?"

I nod my head at her, silently telling her to back down. She thinks she's a hardcore cardio surgeon, but I need to show people I also belong here.

"How about we talk about this in private?"

"Okay but it has to be quick, I have somewhere to be soon."

She leads me to an empty room, and turns around with her arms crossed.

"I have no idea who you think you are, but you can't just take my patients without consulting with me first!" She snapped.

I had to blink a few times, not expecting her to unload on me like that. I take a calming breath and look into her eyes.

"Look, with no disrespect, I'm sure your a great surgeon, but I'm surprised this is your choice of treatment, when you know- there's other ways to do this. I won't have any cardi-

"Look Dr. Robbins, I'm not just ANY cardio surgeon. I'm the best cardio surgeon. So watch what you say."

"No, I'm not saying you're inadequate or anything," I say looking down at my watch."You know what I need to go, I have other patients and I have a meeting I need to be in soon. I'll see you later." With that I take off with my heelys.


CALLIE POV

I stand there in shocked. Did she just skate? I have never been talked down to in my entire life. Not even when I told my parents I was bisexual. And even then they didn't make talk to me like I was less than. I need to find out who this Dr. Robbins is. Just then I look down at my watch and I see the meeting starts in 10 minutes. I make my way to the coffee cart and I see Mark and Addison.

"Hey Torres, just dropped off squirt." He says as he hands me my coffee.

"Hello? Torres? Callie?"

"Huh? What?" I say distracted.

"What's going on? Are you okay?" Addison asked.

"No, I'm not okay. I just met some crazy doctor on the pediatric wing, and she thinks she can just take away my patient. I'm not even sure, that she works here. Wait till she finds out who I am. She's infuriating and she didn't even let me finish my sentence."

Mark laughed as he takes a sip of his coffee. "Wow, I need to meet this doctor. She sounds hot."

"Mmm"

"Wait! You think she's hot." He says as he stops walking.

"I didn't say she's hot." I scoffed.

"Well you didn't say she wasn't hot." Addison teases.

"Whatever, we have a meeting to go to, and I'm gonna talk to whoever the new Head of Peds about this new doctor on her floor."

"Okay, Cal let's go."

Mark, Addison and I walk into the room and most of us is already here. Except the chief.

He walks into the conference room, with all his paperwork in his hand. "Okay, thanks for coming in today. I know we are all busy, so I want to make this quick. As you all know our new head of Peds starts today. So I want you all to welcome her and show her around. He goes to the door, and opens it. In walks the person, who I despised the most. "No that's her Mark." I whispered.

"You're right she is hot." He teased.

"I never called her hot." I whispered roughly.

"Dr. Torres, do you have something you would like to share with the rest of us?" The chief asked

"Umm.. no I don't. Sorry chief." I say elbowing Mark in his arm.

"Good, then you can show Dr. Robbins around."

My eyes go wide, "Actually chief I hav-"

"Nonsense you can spare 15 minutes of your time."

"Chief it's fine. I'll have Jr. do it. He's free." Arizona speaks up

"Jr?" I whisper to myself. Who's Jr?

She looks at Dr. Timothy Robbins, and he gives her a weird look.

"Yes chief, I'll take her on the tour." He laughed.

"Well it's settled. Dr. Robbins will take Dr. Robbins on a tour. We need to figure out a way what to call the two of you before everyone gets confused. Since you guys are siblings." He chuckled.

"Thanks Chief," she says as she takes a seat across of me, giving me a smirk. I can't help but roll my eyes at her. These looks don't go unnoticed to Tim, Mark and Addison.

The Chief talks about the same old hospital business. What we need to improve on. Who's department is doing the best. Finally after 20 minutes he ends the meeting.

"No wonder why she looked familiar, she looks like Tim." I tell Mark as we walk outside the conference room.

"Duh. Torres. I could just look at her and tell she's related to Tim."

"Sorry Mark, I was too mad to even noticed that she looks like him plus the nurse told me she was a doctor, not the head of Peds. That's what I get for believing stupid rumors."

"You like her don't you?" Addison says poking my arm.

"What? No. I can't stand her."

"Sure, you can't." He gives me a shit eating grin.

"Anyways I need to talk to her about my patient before she fucks up my surgery."

"We'll leave you too it."


Arizona POV

"So, what's the deal with you and Torres?" Tim laughed

"What? There's no deal."

"Don't lie to me Arizona, I saw the look she gave the Chief when he asked for her to show you around, and the look you gave me when you said I would take you on it. Not to mention that smirk."

"Timothy, there's nothing."

"She's hot isn't she?"

I roll my eyes at him. "Fine, okay she's hot. Even a blind person could tell she's hot."

"So? What happened? You just started today? What could you have possibly done to piss her off"

"Okay, look we had a disagreement earlier this morning on a patients treatment and I took over her case."

"What?"

"Yeah, she was gonna give a kid an artificial lung, Timothy."

"I can't believe you Arizona, she's the best cardio thoracic surgeon. You can't just go and kick her off a case. You know she's Teddy's boss right? She pretty much taught Teddy everything she knows, and you think Teddy is the best cardio surgeon out there."

"It doesn't matter. Did you hear what I said? Artificial lung on a child!"

All of a sudden, I see Tim look up and he's looking at something behind me. "Ohh, shit Zona."

"What?" I said turning around and seeing a very upset brunette walking my way.

"Looks like you might get that tour after all." He chuckled.

"Tim" Callie smiled.

"Dr. Torres. Well I should get going. I have rounds." He says looking down at his watch.

"Timmy-"

"Gotta go Zona, see you later. Bye Callie."

I cross my arms and look at her, and she is eyeing me up and down. I decide to break the ice. The cold ice that I can see in her eyes.

"Dr. Torres."

"So, why didn't you tell me this morning that you were the new head of Peds?"

"It didn't cross my mind."

"Well you can take my patient."

"Dr. Torres, I have to finish up my rounds. Come to my office in a few hours and we can talk about Riley's case."

"Whatever." She snapped as she brushes right past me.

I inhale her scent as she brushes by and she smells intoxicating. She smelt like warm vanilla. I take a few seconds to gather myself. "Today's gonna be awesome." I quietly say out loud.

"Dr. Robbins?"

"Yes." I say turning around looking at the man calling my name.

"I'm Alex Karev and I was wondering if I could be on your Peds service? I worked with Stark and he was a nut job." He deadpanned.

I'm kinda surprised how blunt the people are here. It's actually refreshing. "Sure, let's see if you can handle my service. I'm gonna let you know right now. I only take the best of the best."

"Got it Dr. Robbins"

"Did you read all the charts?"

"Yes I did."

"Perfect, let's go."
