A/N: So thanks so much for the reviews guys, really appreciate them all! From now on it's going to be my own stuff where Callie and Arizona are concerned...just consider that everything else to do with the shooting happened exactly the same as in the show.

Also, I have no real medical knowledge so if things don't sound right I apologise but I've done my best to research it a tad so that it's right.

Hope you enjoy :D

Callie stood glued to the spot for a good two minutes. She daren't walk out the door and round that corner, not because she was scared of getting hurt herself, but she was absolutely terrified of the scene she would find. Looking at Dr. Sanchez she told her to keep Ruby calm whilst Callie went and checked out the situation. Callie put her head to the door and listened, she heard the double doors that separated the peads ward from the rest of the hospital swing open and shut as someone left...or entered the ward. She listened harder and when she couldn't hear any footsteps decided that the person...she assumed the shooter, had left the ward. Callie panicked at this thought as she could hear no other movement; moving along the wall she listened with every step she took and as she got closer her breathing got heavier as she heard whimpering.

Callie stood still at the edge of the corner, took a couple of deep breaths and turned. The sight before her was something that she would never forget, something that she would see forever, every time she closed her eyes she would see this scene. Arizona was on the floor, on her left side, surrounded by a pool of blood. Callie stood frozen, her brown eyes wide in shock and horror. Fear pumped through her in abundance as the thought flashed into her head that Arizona was dead. She'd not told her she loved her back. Callie's thoughts were interrupted as Arizona's arm moved to her head and she let out a low whimper.

'Aa—aarizona?' Callie gasped her name out as her legs suddenly realised their job and walked forward to the love of her life. She bent down and brushed the blonde hair that was shielding Arizona's face.

Brown meant blue.

'Ca-aaa-llio-pe?' Callie realised she'd been holding her breath as she let out a huge sigh as she realised Arizona was alive.

Arizona was in so much pain; she had never felt pain like it before, well not physically anyway. Seeing Callie's face eased it momentarily but she knew that pain was soon going to take over every single thought she possessed. She replayed the scene in her head. Some man, who she'd never seen before standing, watching her as she rummaged through the shelves for the supplies she had needed, when she'd turned he'd asked her simply if she was a surgeon. When she answered yes he had raised gun. Even though she'd then gone to ramble about being a kid's surgeon and how she needed to save Ruby's life. He didn't seem to care as he fired his gun off three times.

Callie ran her hands over Arizona's body trying to find the shot wounds. Her scrubs were soaked so Callie lifted them up trying to find the source. Arizona coughed, spluttering up some blood with it which caused Callie to search more frantically. Eventually she discovered that there were three bullet wounds: one in her left thigh, one in her right shoulder and the last one in her chest. Callie accessed the situation and knew that the chest wound would be the one that had done the most damage. She grabbed some gauze and bandages from the supply shelves and wrapped Arizona's thigh and shoulder before applying as much pressure as she could on her chest.

'DR. SANCHEZ! HEAR NOW!' Sanchez came running round the corner and looked in horror at the scene before her. 'Look, I know Ruby needs us too but right now I'm running out of ideas here...go grab some nurses from the play room; send a couple to me and use a couple yourself to calm Ruby down as best as you can. I'm gonna ring the police and try and get some help up here...GO!' Sanchez ran off and within seconds two nurses came round the corner, Rachel, who had been on the phone earlier and another nurse who Callie knew as Emma. Both of them mirrored Sanchez's reaction but ran forward grabbing more gauze and applying in to the wounds as Callie showed them where they were.

Callie was trying to stay calm for Arizona's sake, trying to keep her surgeon head firmly on but all she wanted to do was cry. She couldn't die. Callie made a silent prayer to God to keep her alive long enough for them to get her to an OR; she needed her faith to give reward now more than ever. She held Arizona's hand as she tried to keep her talking as Rachel and Emma managed to slow the bleeding down considerably.

'Arizona, come on please just keep your eyes open a little longer for me...' Callie pleaded with her love, hoping that her voice was enough to keep her from falling asleep forever. 'Rachel...ring the police...see if we can get some help...we need surgeons...we need Teddy...and Owen Hunt...fuck it just get anyone you can!' Rachel ran off to the reception.

'Callie.' Arizona could just about talk...it was barely a whisper but Callie bent towards her so she could hear what she was saying. 'I'm sorry.'

'No...no Arizona don't say that...it's going to be fine, Rachel's gone to ring for help...Teddy's going to come up here and sort your chest out and Owen...well he'll be Owen...' Callie's tears fell thick and fast as she struggled to form sentences.

'Don't cry babe...please...it's going to be ok...I love you...and you'll be fine...I promise...'

'NO! Arizona stop...look I love you too...I love you, I love you, I love you...please just hold on...' Callie's words lifted Arizona momentarily but she knew that she didn't have long before the pain and her injuries got the better of her. She was struggling to catch her breath and knew that one of the bullets had probably punctured a lung, so a pneumothorax was forming, eventually there would be so much air in her chest that she wouldn't be able to breathe.

'Callie...you need to put a chest tube...pneumothorax...' Callie gasped as she berated herself for not thinking of that herself. Before she could ask Emma was by her side with a tube and a scalpel.

'W-w-wait...Arizona I've never done one of these before! I c-ccan't do this!' Callie was an orthopaedic surgery the last time she had put in a test tube was in med school and now she had to do it on the woman she loved?

'Calliope...please...I trust you...I love you...and I'm sorry for everything...I shouldn't have given up on us like I did...kids...ten...please...' Arizona's hand slumped to the floor as her head fell to the side.

'NO! Arizona...ARIZONA! No you aren't going to die on me! I can't live without you...I can't live without you...I can live without kids...fuck kids...as long as I've got you...Emma give me the fucking scalpel!' Emma put the scalpel in Callie's shaking hand, the tears dripping down both of their faces.

Callie ran her fingers over Arizona's ribs...one...two...three...four...five...the fifth inter-costal space. Callie drew in a breath and made a small incision before grabbing the tube and stuffing it in. She felt air release so she knew that she had it in the right place but still Arizona's chest didn't move.

'Right we've got tube her...Emma get a tube...a bag...and the defibrillators...NOW!' Callie began CPR, pumping her chest ten times before breathing into her mouth. Emma came running back, with Rachel in tow. Rachel took over CPR whilst Callie moved round to Arizona's head and shoved a tube down her throat. Emma attached the bag and began to breathe for Arizona whilst Callie grabbed the paddles.

'Charge to 270...CLEAR!' Callie shocked Arizona's body. Nothing.

'Charge again! CLEAR!' Nothing.

'CHARGE TO 360...CLEAR!' Nothing.

'AGAIN!' The monitor Rachel had attached let out a small series of bleeps to indicate that Arizona's heart had started up again. Callie sank back onto her heels as Arizona spluttered against the tube.

'Babe...Babe...look at me...' Callie rose above Arizona so that she could look her straight in the eyes. 'Don't resist the tube...I want to leave it in to help you breath ok...with one lung and the blood you've lost you won't manage to do it all by yourself for long.' Callie gave a small smile whilst Arizona grabbed Callie's hand, squeezing to show that she understood.

'Dr. Torres?' Rachel hated to interrupt the intimate moment that the two surgeons were having but she needed to tell them what the police had said.

'Rachel...I think this whole situation at least warrants you to call me Callie.' They exchanged smiles.

'Um...ok...Callie... I spoke to the police, they said that they're clearing the hospital floor by floor, as we're pretty much at the top we're last to go...even though I explained the situation they said that they had to do it their way otherwise they might miss the shooter. I asked them where Teddy or Owen were and they said that they were still in the building somewhere.'

'So they won't come and get us even though Arizona is on fucking deaths door?' Callie instantly regretted the words she had said as tears fell down Arizona's cheeks. 'Shhh shhhh, I'm sorry sweetheart...I shouldn't have said that...' Arizona squeezed her hand again indicating that it was ok. Arizona hated not being able to talk, she wanted to reassure Callie, she wanted to tell her that it was ok and tell her how much she loved her rather than have to express it through my eyes and hand grips.

'Right I'm going to ring Teddy...' Callie waited as the dialling tone sounded, she just prayed that Teddy was still somewhere in the building.

'Hello?' came the muffled voice.

'Teddy? Please tell me you're still in the building?'

'Callie? Yeah I am...I'm just finishing up with a patient with Owen...we're taking him outside to be transported to press why?'

'I need you to come up to paeds...please...Arizona...she's been shot...she's got a pneu...'

'Give me five minutes Callie.' Teddy put the phone down and stood in shock. Arizona, her best friend, had been shot. 'Owen can you take him out on your own?'

'Yeah sure thing...why?'

'Arizona's been shot...I need to go and help...' Teddy turned to walk away.

'Ted! Be careful yeah?'

'You can count on it.' Teddy left Owen and made her way to the stairs. Using all her military training she travelled silently and quickly, checking round every corner and through every door before she went through. When she reached the double doors of paeds she forgot all resolve and bounded through, her feet coming to a standstill as she saw the scene before her. Arizona was laid on the floor, a tube and bag taking over her face, Callie had her in her arms, both of them were covered in Arizona's blood. Two nurses were there also, Teddy didn't recognise them but as paeds nurses she knew that they would be feeling this too as Arizona was a fabulous head of department.

'Callie...talk to me.' Teddy tried to put aside the fact that it was Arizona lying there and tried to think like it was just any patient but as her eyes found Arizona's that became impossible. This was her best friend here.

'Teddy...thank God. She's been shot in three places...her thigh, her shoulder and in her chest. The one in the chest punctured her lung, she's got a pneumothorax...I put the chest tube in but she didn't come round straight away, we had to bag her and in took four shocks to get her back so I've left the tube in to help her out with the breathing. The bleedings under control for now, but as you can see she's lost a lot of blood Teds.' Callie finished as tears began to fall slightly.

'Right ok...shift round a bit Callie and let me have a feel and a look...' Callie shifted so that her legs were now underneath Arizona's head, both of their eyes fixed on each other. Arizona winced as Teddy felt around the tube Callie had put in. 'Sorry sweetheart...right...looks like you did a good job with the tube Cal but we've got to get her to an OR asap. This isn't just a straight pneumothorax...it looks like the bullet not only punctured her lung, but also, because of the angle that it entered her body, it nicked her heart as well, which is why she's having so much trouble breathing even though you put this tube in beautifully...' Teddy smiled, trying to lighten the situation somewhat. 'Now it's not dangerous...at the minute, but you have to understand that as blood is being pumped around Arizona's body and back to her heart...'

'...it's leaking straight out her heart...' Callie finished for Teddy.

'Yeah exactly. Because the hole is small she'll last a bit longer but eventually blood will stop reaching her extremities which obviously includes her brain...we need to get her into an OR within the next hour so I can do a pericardial repair...' Teddy finished her diagnosis looking from Arizona to Callie and back again.

Arizona felt more fear fill her body as she listened to Teddy. She knew about the pneumothorax...she had diagnosed herself with that one...but the bullet had hit her heart too? This really was not good. Arizona gripped onto Callie's hand tight as she saw her looking so worried and hurt by Teddy's words. At the tightening Callie looked down to Arizona and as their eyes met Callie instantly calmed her expression knowing that her panicking was not going to help in the slightest.

'Right...Rachel was it?' The nurse nodded. 'Good, Rachel, go and find a gurney so we can move Arizona.' Rachel ran off to find a free bed.

Arizona began to shake her head and writhe as she caught up with what was going on. What were they thinking? They wanted to move her even though there was some mad man on the loose who obviously had a particular vendetta against surgeons and who'd shot Arizona, not once, but three times? No. She wasn't having any of it. Callie knew as soon as Arizona started writhing what she was protesting to; I mean who wouldn't?

'Shhh...Zona please stop writhing around, you'll only be doing yourself some damage. I know...I know...but we've got to get you to the OR...you won't...l..' Callie couldn't bring herself to say the word 'live', she couldn't let the thought into her head that Arizona might not survive. Arizona squeezed Callie's hand again, she hated not being able to talk. All fight in her faded as she started to feel queasy, the blood loss was taking its toll and if they didn't go now Arizona wouldn't make it down to the fifth floor let alone the OR floor.

Rachel came screeching round the corner with a gurney. Callie lifted Arizona on to it with ease, making her comfortable whilst never letting go of her hand. Before they left the ward Arizona remembered why she had been getting supplies in the first place. Not knowing how to communicate this thought she squeezed Callie's hand again and waved her other hand off in the direction of Ruby's room. Callie understood straight away and her mind went into overdrive.

'Teddy who's down on the OR floor?'

'Um, Owen left with our patient...as far as I know there's the OR team we were using so all the nurses and Avery's in there too...that was when I left, they may have collected more folks by now or they might have all left...I really, really don't know Cal...but between the four of us we can get sort Arizona out just fine...'

'No..you don't understand Teds...there's this girl in that room, Ruby, she's got an appendicitis, she needs surgery too...urgently...that was why Arizona was out here getting supplies in the first place. We have to take her with us.' Callie decided that fact almost immediately and wasn't going to be swayed on it.

'Cal, look we haven't got time to mess around here...'

'Teddy please. This situation is just so...fucked up...and I don't really know how to deal with it but seriously this girl is coming with us...I can't let her die and I can't let Arizona die...between me, you, Rachel, Emma and Dr. Sanchez, we're sorted, we can get them down there and just pray on our way that there are other people still down there to help with both surgeries when we get there.' Callie finished and the look she gave Teddy told her not to argue with her at all.

So that's how it went. Callie walked next to Arizona's bed which Teddy and Rachel were pushing, her hand firmly wrapped around Zona's, then Emma and Sanchez followed pushing little Ruby. They had ended up sedating Ruby slightly as she was in so much pain and making a lot of noise, obviously they didn't want to attract any unwanted attention.

The going was painfully slow; every time they reached a corner or a door, Teddy would leap forwards and check the way was clear. When they made it to the elevator they all breathed a slight sigh of relief as Teddy pushed the button that would take them to the OR floor.

Callie turned to Arizona and kissed her lightly on the forehead, her eyes meeting Arizona's and locking on. 'I love you so much.' Arizona smiled as best as she could and nodded. Callie smiled, knowing that she was saying the she loved her too. As the elevator dinged and signalled they had arrived at the OR floor everyone readied to move once again.

What happened next occurred in such a blur that if any of them had blinked, they would've missed it. As they wheeled towards the theatres there was a lot of commotion coming from within as they heard shouting and beeping. This was odd as Teddy had thought it would be empty. Their thoughts were interrupted as Arizona's vitals dropped through the floor, her eyes rolled back into her head and she flat-lined.

'NO! NO! Not again...ARIZONA YOU STAY WITH ME YOU HEAR!' Callie's voice ran clear and true through the silent halls. She jumped up onto the bed and began CPR straight away. 'TEDDY GET US IN THAT FUCKING OR NOW!'
