A/N: So, this is my very first fanfic. I'm neither a paramedic nor a surgeon, so I don't know if my information is correct but I did a little research. I hope you like it!

Chapter 1

Arizona's POV
'Ambo 16 reporting incoming trauma, four ambo's on route to Seattle Grace Mercy West. Eight patients in total, MVA, SUV collided head on with pick-up truck. We need an Ortho surgeon on scene, Over.' I called over my radio, to the caller on the line.
'Roger that ambo 16, Ortho surgeon ready to go on arrival.' The call came back seconds later, I sighed in relief.
I rounded the corner pulling into the ambulance bay of SGMW hospital and jumped out of my rig.
"Stacie Collieton, 23, facial lacerations, broken wrist, having trouble with her breathing." I announce clearly as I pulled the gurney out of the ambulance.

As two of the doctors rushed Stacie inside, I turned back to the sobbing little girl still seated in the back of my rig. I pick her up into her arms and ran a soothing hand through her hair.
"This is little Kaley, 8 years old, she has small cuts on her forehead, arms and stomach, and an open wound on her right thigh which we fixed up on site, isn't that right Kaley?" I stated, looking to the still sobbing girl, who was staring at me while I talked, her breathing was starting to calm down, Kaley nodded and looked around.
"It's alright sweetie," I cooed softly to her. "Your Aunt is going to be fine, the doctors have taken her inside to get all better and once they make all your sores better they'll let you go and see her, okay?" Kaley nodded again and let me hand her off to the nurse.

'Ari,' I heard my partner call over the radio. 'How are you getting on with the Ortho surgeon?'
'Just gotta find them, then we'll be on our way back, Jules.' I called back.

"Zona!" I heard a familiar voice shout from behind me. I spun around and squealed in delight.

"Teddy!"

While I bounded over and hugged my best friend, I did not notice that Teddy had company. The other woman cleared her throat softly, causing my gaze to shift to her. The moment our eyes met, I felt my heart thud rather violently in my chest. This woman's beauty totally caught me off guard. She was Latina, tall and curvy in all the right places. She had long, dark, flowing hair that hung down to her lower back. With chocolate-brown eyes that seemed to stare right through me and a thousand-watt smile that would light up even the darkest room. I found myself staring, mesmerised, at this mystery woman. I internally berated myself and smiled back, letting my dimples pop full power.
The woman looked momentarily startled and took the smallest of steps backwards, which didn't go amiss, and I now sported a look of confusion.

Teddy silently watched this exchange, and with a thoughtful glance between the two of us, she decided to interrupt.

"Zona, this is our new Ortho attending, Callie Torres. Callie, this is one of our ambo drivers, Arizona Robbins."

I thought her name was gorgeous and fitting, only I couldn't help but think there was something left out. I let it go… for now.

I shook hands with Callie and smirked at my friend. "Oh, just one of your ambo drivers am I Teds?" I said, scowling playfully.

"Yeah…" Teddy shrugged nonchalantly.

"Right, you're so going to get it Altman!" I mock threatened.

"What are you gonna do about it Robbins?" Teddy challenged.

"Hmmm, oh I don't know yet… Just, It'd be best to stay clear of Addie for a while, Teds. She may or may not find out who really stole her chocolate biscuits. You know how much she loves her biscuits"

"Whatever Ari!" Teddy exclaimed, turning bright red and glancing briefly at Callie, who was watching our exchange with amusement, but sobered up when I mentioned Addie's name.

"Addie…? Do you mean Addison Montgomery?" She asked quickly.

I opened her mouth to say something but was cut off by a screech through my radio.
'ARIZONA TASHA ROBBINS! WOULD YOU GET YOUR ASS BACK HERE WITH THAT DAMN ORTHO SURGEON!'I cringed at the use of my full name, I was definitely in trouble.

'On our way, Jules.'I called back.

"We should get going," I said to Callie who nodded and picked her bag up from the ground. "This isn't over Robbins!" Teddy yelled at my retreating form.
I turned back around and poked my tongue out childishly at my friend. Callie snickered beside me, causing me to turn to her and pout. Callie's eyes grew wide as they focused on my protruding bottom lip and she sucked in a sharp breath, subconsciously biting her own.

As we reached the ambulance and climbed in, I glanced sideways at Callie who was looking slightly flustered and was squirming a little in her seat.

"You alright there?" I asked softly as I started up the engine.

"Y-yeah, I'm just… Yeah." Callie stuttered.

I nodded once and focused back on pulling the ambulance into the busy Seattle traffic. I flicked the lights and siren on and sped off to the crash site.

Callie's POV
Teddy was showing me around the hospital when our pagers went crazy; 911 in the pit. We raced downstairs and outside, where we found chief Hunt giving out orders.

"Owen," Teddy called. "Where do you need us?"

"Teddy, thank god. Multiple MVA's, I need a cardio consult inside. Dr Torres, I'm sorry to throw you into it on your first day but they need an Ortho surgeon on scene." Owen gushed out before turning and hurrying inside. Just before he entered the ER, he called back over his shoulder. "Teddy, I think Robbins is coming for her… Ambo 16."

Teddy nodded and turned, scanning the immediate area, for whom I assumed was Robbins.

I watched as an ambulance pulled up and a breathtakingly gorgeous blonde woman jumped out of the drivers' seat. I watched as the paramedic darted around to the back of the rig and started unloading her patients. Completely mesmerised, I forgot that Teddy was standing beside me until she yelled out to someone, making me jump violently. When I got my breathing back under control, I focused on Teddy who was hugging the mystery blonde that I was just watching. I cleared my throat softly causing the blonde to look over at me. Wow if I thought she was breath-taking from afar it was nothing to how she looked up close.

She had soft blonde curls that were tied up in a loose ponytail, a few free strands framed her porcelain face. Her pink, plump lips looked enticing. But it was her stunning, electric-blue eyes that caught my attention. I stared in awe of this woman and felt a smile creep on my face at the sight of her slightly shorter form. The woman just looked at me for a few seconds before smiling back. I swear my heart melt a little at this woman's smile. And oh god… those dimples, I actually took a small step backwards in shock of those amazing dimples. Now my blonde beauty held an adorable look of confusion. Thankfully Teddy chose that moment to take pity on us and interrupted.

"Zona, this is our new Ortho attending, Callie Torres. Callie this is one of our ambo drivers Arizona Robbins."

Arizona, I thought dreamily.

I stood there silently while the two bickered, until I heard a familiar name slip out of my blonde bomb-shell's mouth.

"Addie…?" I asked incredulously. "Do you mean Addison Montgomery?"

As Arizona opened her mouth to answer my question, an annoyed voice called through her radio. She replied to her partners call and told me we should leave, I got my things from beside my feet and followed her.
Teddy called out to Arizona and she turned to poke her tongue out at her friend. I chuckled amusedly at her childish action and she turned to me pouting. My eyes widened at the seemingly innocent gesture as a flash of arousal went through my body, settling low in my stomach. I gasped sharply and pulled my bottom lip between my teeth. I bit down hard and tore my eyes away. We reached the ambulance and slipped inside. I couldn't keep my emotions in check and started squirming in my seat. I couldn't deny my immediate attraction to the blonde, but I didn't know anything about her besides her name and profession. I had no indication that she was even into women. This thinking would get me nowhere. When Arizona asked if I was alright, I stuttered out a lame answer before internally face-palming.

Professional mode Callie. I thought to myself. You're a badass surgeon and ex-marine for Christ sake, not some teenage girl with her first crush. Get a grip.

"So, how do you know Addison?" Arizona asked, quickly glancing my way before fixing her eyes on the road again.

I schooled my features as I looked at Arizona. "Uh, our parents are good friends. We've been best friends since we were kids. She's like a sister to me." I answered with a smile.

"Ahh… You must be her 'Hot Latina Mama' that she always talks to on the phone. Her words not mine." At my confusion, she added. "I'm her roommate."

"So you must be her 'Blue-eyed Blonde Beauty,'" I laughed at my friend's nickname for me.

Arizona giggled adorably. "She called me that?"

I nodded "Yeah. I always said that woman was insane."

Arizona hummed in agreement as she pulled up to the crash scene.
