He was losing too much blood and the paramedics were just kneeling down to get treatment started – one of them even looked appalled at my use of first aid; I glared at him and yelled that I was a combat medic and knew what I was doing in the field and for him to get his ass in gear and start fluids. I leaned down and checked the blood flow, it had slowed considerably but he was in shock and drifting in and out of consciousness – I slapped him again and he snapped up and looked at me.

"Don't you dare go to sleep Gregory Parker – you scare the shit out of me again and I will roast your balls for breakfast!" I yelled as the adrenaline took over and I helped the paramedics set up vital checks.

We got him stabilized and transported into the ambulance where his heart stopped suddenly – I grabbed the panels and charged them up – he was not giving up this fight – he was stronger than this!

"He's lost too much blood Officer!" the paramedics said.

"Then get a cannula started and do a direct transfusion from me to him – his blood type is O Positive and I am O Negative – take what is needed!" I yelled back.

The other paramedic kicked into action and swapped places with the newbie guy, he got what was needed done while I continued to work on Parker and managed to get his heart going after a good dose of adrenaline. His stomach wound was still bleeding freely after the compressions and I had to jam my thumb back into the wound and press down on the artery that had been nicked by the bullet. I felt the sharp nick of the needle going in my arm and I straddled his legs again to give the transfusion the gravity drop it needed.

"Boss – I need you to stay awake alright – stay with me!" I whispered into his ear.

He looked at me and groaned, we couldn't give him anymore painkillers and the ride to the hospital wasn't the smoothest in the planet – I tried to keep him as steady as possible by balancing myself on top of his legs and his vitals were showing he was heading back into shock as his brain processed what was going on. We needed to keep him calm and I clocked the radio in the dashboard.

"Give him another IV and put the music up in the back, got an idea to keep him calm enough to slow the blood loss," I called over the noise of the siren.

I leaned down closer to him and started to sing along to the song, he always teased me about singing in the Humvee – time to put it to good use! The paramedic was about to give him medication through the IV and I stopped him quickly once I clocked the container – it would kill him within seconds. Parker was allergic to certain medications and I was making sure none were given to him, but one of the main ones was the Factor Vlla that helped treat blood loss. The blood transfusion was helping as much as possible but I was starting to feel the effects of it since it was going from me to Parker and then the pressure bandage in set order. The IV's were helping treating the shock and the LR Solution was working wonders for his vitals that were showing 79/67 with a pulse rate of 34. I looked up through the windscreen and saw we were close to the hospital and they driver had called ahead for the trauma unit to be ready for our arrival. Thirty seconds later we hammered to a stop outside the ER and wheeled out on the gurney into the ER trauma unit. I gave the doctors a rundown of what happened and all the details they would need, I sat still as they told me to keep applying pressure to the wound and I would be going to the OR with them and then released once clamps were applied. I had the cannula ripped out my arm and bandaged up quickly and a face shield put over my hat, surgical drapes were put over us both as we were wheeled up to the OR and I kept whispering to Parker to stay strong and we would see him in a couple of hours. After five minutes I was released from the OR and I headed to the bathroom to try and wash as much blood from my hands as possible – the whole front of my uniform and vest was saturated and I had blood on my face and hair and even my trouser legs were covered in it – I looked like I had just been in a slaughter house. I looked in the mirror and took a deep breath; checking my weapon didn't have any ammo in the barrel, I put it into the patients clothing bag and sealed it up with a set of handcuff ties before heading out the bathroom and down to the waiting room.

The nurses had kept the room empty after seeing the state of me covered in blood and offered a set of scrubs and shower kit if I needed it – I refused knowing the SIU was going to want all my gear in the next couple of hours anyway. I took the bottle of water they offered after they found out I had donated on the way over and slid down the wall and landed on the floor; I looked up and saw in the mirror the massive red streak I had left against the wall as I slid down. Bringing up my knees, I rested my head and started the sniper breathing technique to calm myself down so I could explain once the others arrived.

"Mac – we are coming up the main entrance – where are you?" a voice came over the comms unit.

"Emm, seventh floor, east wing – surgical department," I replied.

Two minutes later I heard them out in the corridor asking where I was and then the door opened and they all came in; they took the scene of me sitting on the floor covered in blood and Jules had to leave the room.

"Mac – are you alright?" Sam asked as he knelt beside me.

"Greg's surgery is going well according to the last update and the body of the shooter has been transported to the morgue by the SIU. Ed, my weapon is in the clothes bag – can you secure if for me?" I replied.

"Done and secured with Jules – are you alright?" Ed demanded.

I stayed silent and looking at a point on the wall to keep myself focused on the job now at hand and what SIU would be asking me.

"Mackenzie where are you hurt, you're bleeding!" Ed hissed as he saw my wrist.

He looked at Sam and he shook his head at him.

"Ed she's slipped into medic mode and you won't get answers!" Sam whispered.

Sam had to put on gloves to help me up since I was unable to remove my clothes, I was exhausted and we still had to go back to the barn to debrief and follow the SIU investigation team's questions. The door opened and the nurse handed me another bottle of water and told me to drink it to replace my fluids – I complied since I was feeling like crap.

Ed stepped out and talked to the medical team who were getting reports from the OR and he seemed satisfied to allow Jules to stay here while I headed back to the barn to wash up; I grabbed a blanket and wrapped it around myself to protect the evidence from the uniform and also the backseats of the Humvee – blood was a nightmare to get out of fabric! Sam took me by the elbow and lead me to the elevator where Spike was holding it open after parking up – he looked horrified at me and I was fighting back tears as the adrenaline was wearing off – Sam recognised that and he moved us quicker through the crowd that was forming.

Ten minutes later I was in the back of the transport and looking out the window, I was still praying that Parker was going to make it and make a full recovery – infection and blood loss were the biggest problems for his recovery and I had donated roughly two pints in short time and needed time to recovery myself. I was handed another bottle of water and sipped it – if I drank anymore I was going to need a stop at the bathroom on the way to the barn. Ed took glances at me as he drove and Spike was sitting in the front with him as Sam kept a close eye on me in case I took a turn due to shock.

"You need to keep your fluids up and we will get you something easy to eat once you're cleaned up. You did great with the boss – I know because of your care he will survive." He whispered.

"Sam how is she doing – how's her reaction?" Spike adds as he contacts Jules for an update via text message.

"I'm alright guys, I'm just tired," I whisper.
