Wrong timing

Part I

Mark's POV

Callie stepped next to me with an annoyed and sad look. "Ugh, I hate this lock down. I was supposed to have three surgeries today and now I am stuck here in the lobby", she whined, putting her head on the counter.

I looked up from my chart and watched her intently. She didn't look like herself anymore. The fire from her eyes was gone and her shoulders were slumped down in defeat. I hated to see her like that.

"Are you okay?", I asked compassionately. I knew she was not okay. After her break up with Arizona she had been like a zombie, just walking around and doing her job without showing any emotions.

"Yeah, I just need some distraction to get my mind off of Arizona for at least a little while. You know, surgeries would have been good, but thanks to that lockdown...", she started rambling.

I looked back at my chart, only listening to her half heartily. I knew what she was going through and I wish I could help her, but most of the time my own mind was occupied by another blonde. I told Lexie that I was still in love with her, but she didn't want to hear it.

Speaking of Lexie. She was making her way over to us and asking me to sign something.

"Lock down", I changed the subject without looking at her, "kind of crazy, right? You think it's.. uh.. serious?"

"Can you just sign the.."

I interjected again. "Is this Karev thing serious?"

"Mark!", her voice was getting more serious. Callie had stopped whining and paid more attention to our conversation.

I finally looked at Lexie. "I miss you", I told her genuinely.

"Can you just sign the order?", she asked, or rather ordered, slightly annoyed.

I looked back at the chart with no intention of signing the order, while a nurse told some guy, who wanted to leave, to stay here because of the lock down.

Callie got up and made her way towards Lexie to sign her form, as the guy suddenly pulled out a gun, aimed at the nurse and pulled the trigger.

Callie's POV

I had gotten up from my place on the counter to sign Lexie's order. This lock down thing didn't really strike me as serious or even alarming. I thought it was some kind of exercise and didn't even pay attention to the guy, who was trying to leave the lobby.

Suddenly I heard two shots. Instantly people started screaming and running around. Mark grabbed Lexie and pulled her down behind the counter. Completely shocked I stared at the gunman, then at the nurse, who was now lying at my feet.

The third shot brought me out of my shock and I let myself collapse on the floor to get out of the way. Right next to me Mark was covering Lexie, who tried to make her way to the shot nurse.

"No, no, no", Lexie's voice was high. "She's dead, she's dead."

Mark grabbed Lexie with one hand and me with the other to get us away from here. I had no idea where the gunman was, so I blindly followed my best friend. People were still running around, screaming and panicking.

Mark's POV

When I realized that Callie was following me, I let go of her hand and shielded Lexie with both of mine. We made our way through the panicking people to the elevator. I desperately punched the button, willing it to hurry.

"Come on! Come on!", I screamed, the only thought in my head was to get Lexie as far away from here as possible.

As the doors finally opened I wish we had taken the stairs.

Lexie's POV

Someone had just been shot right in front of me. I was in shock, hardly taking in my surroundings. As a doctor I have seen people die, but nothing compared to what I just had witnessed.

Gladly Mark was there to pull me away from the dead nurse. As I heard the sound that announced the arrival of an elevator I was brought out of my shock. I let go of Mark, ready to step into the saving elevator, but as the doors opened I stopped dead in my tracks.

Right there in front of us was Alex, lying in blood and not moving. I stumbled, Mark still had a hold of me, which prevented me from falling down.

Callie's POV

"Get in the elevator!", I ordered and pushed them in. Even if Alex was lying there, it was probably the only safe way away from here.

Lexie clung onto Mark, as they entered the elevator, I followed quickly, allowing the doors to close.

I let out a small breath I didn't realize I was holding. We were safe from the gunman, at least for now.

I leaned over Alex and checked his pulse. It was week, but it was there. I signed relieved. "He's alive", I told a completely distraught Lexie.

Checking his side, I saw a bullet hole to his chest. "We need to get him out of here", I told Mark.

The elevator made it's way to the second floor and away from the shooter. As the doors opened I carefully peeked outside, while Mark picked up Alex, earning a painful moan from the young surgeon.

Taking Lexie by her hand and leading her out of the elevator I made my way to an empty conference room. Mark heaved Alex on the table, while I went back to get some medical supplies from one of the closets.

The hallways were deserted. Every sound made my heart pound a little faster. But there was no one here, I tried to tell myself. I had seen the shooter making his way upstairs, and we were downstairs. But still, I couldn't help but feel paranoid, which also made me feel a little dizzy and weightless. This could also be due to the adrenalin pumping through my veins.

When I got back Alex was conscious. I can't even begin to imagine the kind of pain he must be in right now. He growled some words, but in my ears the blood was pumping too loudly now to understand him.

Mark's POV

"That son of incredibly bitch of right now!", Karev cursed.

"Alex, you've been shot", I try to hold him still, while explaining the situation to him. Lexie was begging me to get him out of here, afraid the gunman would come back soon.

Looking Karev up and down I couldn't find an exit wound. I looked up for Callie to help me. She just came back, after gathering some medical supplies. She dropped them on the table, some of them falling to the floor.

As I looked at her closely all thoughts about Karev vanished from my mind and I yelled out in shock: "Callie, you're bleeding!"

Callie POV

"Callie, you're bleeding!", Mark yelled at me. His yell was loud enough to reach my ears.

"What?", I look down on my scrub shirt. It was indeed soaked with blood, but it wasn't mine. "No, that's Karev's blood", I told him, pointing at my shirt.

"No, you're shoulder!", Mark exclaimed loudly, shock written all over his face.

I looked on my left shoulder, there was no blood. I looked to my right and was shocked. Blood was streaming out of a wound in my shoulder, down my arm and dripping off my fingers. Unbelieving I touched my right shoulder with my left hand. I didn't feel any pain. I looked under my scrub shirt and discovered a bullet hole directly over my clavicle. I touched it, suddenly pain is cursing through my body, more blood was spilling over my fingers and before I realized what was happening my head hit the floor.

Mark's POV

Callie stared at her shoulder in disbelieve, like she didn't even realize she had been shot. Maybe she didn't. Maybe the shock and the adrenalin had prevented her from feeling any pain.

"Callie! How bad is it?", I ask her, desperately needing to hear that my best friend was okay. But she didn't seem to hear me. Trance-like she touched her shoulder, as if it didn't belong to her body and she needed to feel it, for it to be real. "Callie!", I tried again. But no answer.

She looked under her scrub shirt. As she touched the bare skin on her shoulder her face changed to a pained expression. Before either me or Lexie could react she collapsed on the floor.

"Lexie! Get her some bandages, we need to stop the bleeding!", I yelled. Finally Lexie snapped out of her shock and into surgeon mode.
