You and Mark broke up over a month ago. You think he's over you, you always see him hanging out with nurses, you see him sleeping with several women. But the truth is he's never over you.

You were walking around the ER, suturing, cleaning wounds, giving medicine. You just wanted to do surgery. Bailey asked you to go over to Mark so he could sign an important document. There you were.

"Mark I just want you to sign - You ask patiently."

  Are you and Karev together?

"Mark, please..."

  What do you think about going to the bar today? I miss you. - He teased with a little smile just to see her angry expression.

You were about to argue with him. When you were interrupted by a man shooting four people. Mark grabbed you and threw you to the ground, you were shocked to see dead and injured people. You entered the elevator, and there was Karev unconscious.

You and Mark were in shock. You hid in a room, the hospital was so silent that it would scare anyone. The shooter was going through each floor looking for Derek.

Karev would die without a blood transfusion. Mark tried to stitch up Karev's wound, but it wasn't working.

You walked down the hallway slowly, pushing a cart full of blood bags, trying to make as little noise as possible. When you looked ahead, Mr. Clark was pointing a gun at you.

  You turned off my wife's life support. It's all your fault!

The last thing you remember is the loud, shrill sound making your ears burn.
