Arizona rushed to the chief's office and pulled open the door. As she walked in, she saw that Owen was on the phone. He held up his finger, indicating that he needed a moment. Arizona nervously paced back and forth as she waited for him to hang up.

"Dr. Robbins, how can I help you?" he said, placing the phone back on the receiver.

"I did something. Something that you need to be aware of."

Owen looked at her, concern evident on his face.

"Of course. Would you like to have a seat?"

Arizona nodded and walked over to the chair. She sat down and pulled her scrub cap off her head. She laid it on his desk and looked up at him hesitantly.

"Dr. Robbins?"

"Yes Dr. Hunt."

"What is it that I need to be aware of?"

As Arizona opened her mouth to speak, the door opened once again. Owen and Arizona both looked at the doorway and watched as Callie rushed in.

"She didn't do anything wrong!" Callie exclaimed as she came to a halt.

"Dr. Torres?" Owen said.

"Whatever she told you, it wasn't her fault. It was a mistake. They happen in surgeries all the time. She…she didn't do anything wrong."

Owen looked at Arizona and sat down in his chair.

"Dr. Robbins. I think it's time you told me what the hell is going on."

Callie looked at Owen and then at Arizona. She hadn't told him yet. She had gotten there in time. But just as she sighed with relief, the door suddenly opened again and in walked Alex.

"Dr. Hunt, she's distraught and letting her emotions take over. She's incredibly upset so she's saying things that aren't true. Don't…"

Alex stopped mid-sentence when he saw Callie in the room.

"I told you I was going to handle this," he said.

"Oh buzz off Alex," Callie replied. "Since when are you my boss?"

Owen stood up and slammed his hands on his desk.

"Enough!" he yelled. "Somebody better tell me what the hell is going on right now!"

Alex walked over and sat in the chair next to Arizona.

"We had a surgery Dr. Hunt. A tonsillectomy on a 10-year old. Everything was going according to plan when an unforeseen complication arose. We.."

"Alex, stop," Arizona said.

"We made the decision to continue with the surgery. Both of us but..."

"Alex I said stop!" Arizona exclaimed.

He stopped talking and looked at her.

"Arizona…" he whispered. "I'm trying to protect you."

Arizona smiled sadly and placed her hand on his. "I need you to stop fighting my battles for me Alex."

Alex furrowed his brow and looked at Hunt and then at Callie.

"Fine," he muttered. "Do what you have to."

Arizona looked at Hunt and took a deep breath.

"I took an unnecessary risk in the OR Dr. Hunt. The child's tonsils were inflamed. I should have closed. Dr. Karev advised me to close, but I insisted that we continue. When I made the final cut, I failed to notice how close his artery was to the site. I nicked it and he began to bleed out. We tried cauterizing, transfusions, everything I could think of. However, we couldn't control the bleeding and he ultimately bled out. He was pronounced dead at 1556."

Owen slowly looked between Arizona and Alex.

"Dr. Karev," he said. "Is this true?"

Alex clenched his jaw and stood up.

"This is ridiculous. We were both in that OR. She didn't make me do anything I didn't want to do. This is no more her fault than mine."

Owen sighed and looked up at Callie.

"Dr. Torres, can you give us a moment please?"

Callie looked at Arizona but Arizona's head was bent down looking at the floor. She didn't make a single move to look back at her.

"No problem. I'll wait outside," she said, hoping that Arizona heard her.

Owen stood up and looked out the window overlooking the hospital.

"We'll need to do an investigation," he said. "I'm not saying that either of you did anything wrong but a child is dead. We can't just look the other way."

"Wait..what does that mean?" Alex asked.

"It means you are on leave until we are able to discern whether or not the decisions made in that OR were reckless. You need to leave the hospital as soon possible."

"With all due respect Dr. Hunt I'm not going to let you do that," Arizona said.

"Excuse me?" Owen said.

"Dr. Karev had nothing to do with this. He made a sound decision that I refused to comply with. He shouldn't be suspended."

"Well with all due respect Dr. Robbins," Owen said, beginning to raise his voice, "I am the chief of this hospital so I will make whatever decision I deem fit. And the last time I checked you and Dr. Karev were co-chiefs of pediatric surgery. That means you hold equal responsibility. You will both be on paid leave until I tell you otherwise. Is that understood?"

"Yes," Arizona said quietly, glancing in Alex's direction out of the corner of her eye.

"I'll see to it that your surgeries are reassigned. Get your things and leave the premises," Owen said. "You are dismissed."

Callie stood outside Owen's office and rested her head against the wall. She couldn't believe that Arizona had gone to the chief of surgery. She could single-handedly destroy her reputation, her career. All because she blamed herself in a situation where an impossible decision had to made. Alex had been right, so many factors came into play in that OR and Arizona couldn't possibly know if a different course of action could have saved the boy's life. But she had convinced herself that her decision and the course of action she had chosen had been what led to his death.

She kept glancing between her watch and the door. It killed her not to know what was going on there. Not to know what was going through Arizona's head. She understood Alex was trying to protect Arizona, but he was really starting to piss her off. She was doing her damnedest to live up to the impossible expectations he had set for her, but she was beginning to realize that he was looking to trip her up at any turn. He was that convinced that she was going to hurt Arizona again.

Callie's thoughts were interrupted when the door finally opened. Alex and Arizona walked out, both looking worse for wear. The day had clearly taken a toll on them and they were physically, emotionally and mentally exhausted.

"Arizona…" Callie said, starting to walk towards her.

"We have to get out of here. Let's go Arizona," Alex said, looping his arm through hers and starting to turn to walk away.

"Alex," Arizona said, removing her arm from his and taking a step back. "I meant what I said in there. I need you to stop fighting my battles for me."

Alex looked slightly hurt before shaking his head and walking closer to Arizona.

"I'm just looking out for you. I want what's best for you," he whispered, trying to reason with her.

"I know Alex but enough is enough. I need you to be my friend, not my bodyguard. We're reaching a crossroads here. You say you support me, you say you can handle this, but your every action and your every word indicate otherwise. And I don't want to be put in a position where I have to choose. Because I'll choose her Alex. I will always choose her."

Alex sighed and his facial expression softened. "I'm sorry. I know I promised. And I-I'm not going to make you choose."

He then turned to Callie. "I'm trusting you. Honestly, I don't know what reason I have to trust you other than her and her belief in you," he said pointing at Arizona, "but…you don't have to worry about me getting in the way anymore."

He turned back to Arizona and put his hands on her shoulders. "I'll get your stuff for you. You guys should talk. I'll see you at home," he said, brushing his lips lightly against her temple and walking away.

Callie slowly approached Arizona, not sure how to act since she couldn't exactly gauge what Arizona was feeling.

"What…are you…I don't really know…" Callie stuttered, not able to slow her mind down long enough to get a coherent thought out.

"I have to get off hospital property," Arizona said softly. "Maybe we should talk somewhere else."

"I'm off in a few hours. Can I come see you?" Callie asked.

"Yeah, I'll be at home. I'll see you a little later," Arizona said, turning and walking away.

Callie's stomach had been churning the last few hours of her shift. She knew she hadn't really done anything wrong. She hadn't wanted Brooke to turn to her for comfort. Above all else she was a doctor. She had seen hundreds of people in moments of unimaginable grief. So in her mind, she hadn't been comforting her ex-girlfriend; she had been comforting a woman who had just lost her nephew.

But she also knew that Brooke likely hadn't turned to her for comfort because she was a doctor. She turned to her because of their past personal history. And she wasn't sure which viewpoint Arizona was looking at this whole thing from. That's why she just needed to see her. She so desperately needed to see her.

So as soon as her shift ended, she picked up Sofia and ran her home to meet the sitter. She threw on a change of clothes and hopped in her car, breaking a few traffic laws to get Alex's house as soon as she possibly could.

She hurriedly knocked on the door and after a few seconds, Alex answered.

"Callie, is everything okay?" he asked, upon seeing her on his doorstep.

"Yeah I just came to talk to Arizona," she said.

Alex looked at her with a confused look on his face.

"Arizona? She's not here. I thought she was with you," he said.

Panic quickly overtook Callie. "She never came home?" she asked. "She told me she would be here. I had to finish my shift and she told me she would be here. Where the hell is she?"

Alex grabbed his jacket and pulled the door shut.

"I don't know," he said. "But we'll find her."

Callie stared at him, fear in her eyes. He wrapped his arm around her shoulders and gave her squeeze, trying to give her some semblance of reassurance.

"Callie, don't worry...we will," he said.

She quickly pulled her phone out of her purse and began walking towards the car.

"I'll try calling her. You drive," Callie said, tossing him the keys and climbing into the passenger seat.

Alex nodded and started the car, revving the engine and peeling out of the driveway. As they sped down the road, they both only had one question on their minds: Where the hell was Arizona?
