Callie was lost in a sea of thoughts and emotions. She kept replaying what had transpired in the OR over and over again, hoping every time that the outcome would be different. That what had happened had all been a dream. That she was actually at home, in her bed with Arizona in her arms. Instead, she kept finding herself in the same chair where Cristina and Sloan had led her. Callie was staring at her shaking hands when she heard Webber approach.

"What happened?" Webber asked to no one in particular.

At that point, Callie looked up and realized that the room had filled with people. People whispering, people gossiping, people staring. She had been so numb that not even the buzzing of voices had penetrated her thoughts. But now, outside the sanctuary of her breaking heart, Callie found herself overwhelmed, unable to speak.

Webber, following Callie's eyes and seeing the pained look on her face, barked, "The police has been notified and is on their way… Now everybody get back to work! This is still a hospital with patients that require your attention! We need you now more alert than ever!"

"Uh Chief? What about the patients and surgeries scheduled on the board?" Bailey asked.

"Clear them all out. Set up surgical rooms in the 3rd floor. No one… and I mean no one go near that OR!" Webber continued.

Callie felt a hand on her shoulder, "Are you going to be okay?" Bailey asked, "Do you need anything?"

"No… No. I just want to be here. Just… here," Callie said.

Bailey turned to look over one shoulder, then the other, "Com'on people! You heard the Chief… Get your butts in gear before I give ya'll something to really talk about! Bunch-a nosey-bodies…" Bailey ordered with her hands on her waist, "And nobody enters this room without MY permission…. Got that?"

Bailey turned back towards Callie and leaned in, "Now I am going to check back in with you every 10 minutes, okay?"

Callie gave her a weak smile and watched as Bailey softly closed the door of the waiting room behind her.

"It's your turn to hold up your end of the bargain," James coldly told Arizona.

Arizona tried to steady her breathing. "I don…" She started.

James swung his arm up and pulled the trigger.

Bailey closed the door softly, her chest heavy for both women. She turned around to find the Chief standing near and gave him a nod.

The Chief rubbed his eyes, feeling the stress of today pushing him down. Heading towards the front of the hospital, he patted Meredith on the shoulder on his way out.

Meredith held Cristina who was still in shock. She smiled at Hunt who had finished giving the new Interns directions.

BANG!

Hunt stood frozen, half knowing, half hoping it wasn't what he thought it was. He looked at Izzie who had popped up from her lounging position on one of the chairs.

Izzie heard the slam of the waiting room doors as it was thrown open by Callie who was now running at full speed down the hallway. She screamed, "Alex!" to get his attention.

Alex who was leaning against the nurse's counter muttered "Shit!" He ran after her, and upon spying Sloan and Derek running towards the OR, screamed "Stop her!"

Derek and Sloan turned around and realized Callie's intentions. They retraced their steps preparing to intercept her.

Callie turned right on an adjacent hallway and bounded up the stairs, heading straight for the viewing station. Once she was in, she slammed the door shut and bolted the locks.

Callie leaned on the door to catch her breath, as the sound of fists banging on the doors and yells to open up ensued. Remembering what brought her there, she ran to the glass window and saw Arizona doubled over on the floor.

Callie let out a cry of anguish so piercing that it silenced everyone on the other side.
