Arizona watched the family through the window of the waiting room. She looked at each one of them and remembered. She remembered how she had watched them grow, child by child. She remembered being there for their births, being there for their complications, she remembered always being there. And because she had always been there, they trusted her. They had placed their child's life in her hands and trusted her with him. And now, she had to tell them that she had let them down. That their son had died by her hands.

This wasn't like telling a family that their loved one who had been sick and ailing for months or years was finally at peace. That was an easier task. By telling a family about that type of passing, you are able to provide some iota of comfort and closure. But this…this was a conversation they were never supposed to have. She hadn't really even prepared them for it because the possibility was so remote. And that was her fault. It was her job to make sure they knew the risks, but she had rushed over them as if they were impossibilities. Things they shouldn't even give a second thought to. But one of those impossibilities had happened. And Arizona now had to stand in front of this family and tell them that their life as they knew it was no more.

Arizona moved to walk through the door when an arm pulled her back.

"You aren't doing this."

"Alex…let me go."

"You are in no condition to break this news to that family. They are going to need answers, answers that you aren't going to be able give. You are going to try and tell them that this is your fault. And they will believe you. And then they will more than likely sue you. Is that what you want?"

"I killed their son Alex."

"You didn't do anything but try and save their son. Would he have survived if we closed? Maybe. But maybe he would have gotten an infection. An infection that would have traveled to his heart and killed him before we were ever able to detect it. Or his airway could have been cut off, suffocating him. He could have died a slow and painful death. Arizona, we aren't God. We don't hold all the answers. We do what we can, but we can't save them all. We just can't."

"He was ten. He was getting his tonsils out. We don't lose those Alex. We don't."

"But we did. And that family needs to know. You don't need to be the one to tell them. You shouldn't be the one to tell them."

"You aren't talking me out of this Alex so back the hell off."

Alex weighed his options and realized that no matter what he said, he wasn't going to able to change her mind. But she was too invested, too close to the situation. So if he couldn't stop her, he was at least going to be there with her.

"We were in there together. We're going to do this together too," he said.

Arizona paused before nodding her head. "Okay, let's go."

Callie waited and waited but she didn't hear from Arizona or Alex. She was going crazy. She didn't know if Arizona had told them or if Alex had gotten there in time. Was she okay? Was he with her? There were just too many things she didn't know. And she would be damned if she was just going to sit on her hands. So she decided to make her way to the waiting room to see what in the hell was going on.

Arizona and Alex approached the family, a grim look on their faces.

"Dr. Robbins, Dr. Karev!" Mrs. Hendricks, the mother of the boy, said as she happily stood up from her seat. "Is he awake yet? Can we see him?"

Arizona froze up, stopping in her tracks and standing as still as a statue. Alex walked over and placed his hand on Mrs. Hendricks' back, sitting her back down in her seat.

"Mrs. Hendricks, there were some complications in your son's surgery," he said.

"Complications? What do you mean?"

"Mom…what is he saying? Where's Ben?" one of the sisters of the boy asked.

"His tonsils were more inflamed than we originally thought. We had to proceed with the surgery. His risks for infection or blockage of his airway were very high. When someone's tonsils are that large though, the surgery becomes more difficult. One of his arteries was very close to his tonsils. He began to bleed out and despite our best efforts we were not able to stop it. Ben has never had surgery, so we were not aware of his difficulty with clotting. There was nothing we could do. I am so sorry Mrs. Hendricks, but Ben didn't make it."

"W-Wh-What do you mean? Where's Ben? Where's my son?!" she screamed.

"Mrs. Hendricks…" Arizona began, struggling to find words. Any words other than the ones she so desperately wanted to say…that she had killed their son.

"Mrs. Hendricks, we understand how difficult this must be and we will give you whatever you need. If you would like to see him, we can arrange that. If you need help with anything..anything at all, we will see to it that you are accommodated," Alex said.

"Dr. Robbins! This isn't true. He…this…tell me this isn't true!" Mrs. Hendricks pleaded with her.

"I-I'm so sorry Mary but.." Arizona started.

"You said this was routine! You said he would be fine! What did you do?!" she yelled, as Alex grabbed her arms in an attempt to keep her calm.

"Mary…what's going on?" a woman said, approaching the hysterical mother.

Arizona had tunnel vision. She was no longer aware of her surroundings. Just the pounding of her heart in her ears.

"He's dead. Ben is…he's dead," the mother said, clutching onto the woman as tears spilled over on her face.

Just then, Callie turned the corner and saw Alex and Arizona standing with the family. Alex looked as though he was trying to provide what little comfort he could while Arizona…Arizona looked like a ghost. Her face was pale and she was standing slightly behind Alex, motionless.

"What do you mean? What-What happened?" the woman asked, confused since she had just walked back into the room. "Doctor..can you please tell me what happened? This is my sister…I'm Ben's aunt. I need to know what happened."

Alex sat down with the woman and explained everything he had just told Ben's mother. The father stood in the corner of the room with the children, not saying a word, just holding them and crying.

Callie stood outside and contemplated whether or not she should enter the room. She wasn't even looking at the family, only Arizona who was clearly drowning. She finally decided that she needed to be in that room so walked through the door.

"Callie?"

Callie heard her name upon entering the room and looked at Arizona, only Arizona wasn't looking back. Who had said it? She shifted her eyes over to Alex and saw the woman sitting next to him. It only took her a second to realize who the woman was…it was Brooke.

Alex looked between the woman who had said she was Ben's aunt and Callie wondering how they knew each other. Then he saw Ben's father heading for Arizona and jumped up to cut off his path.

"I demand to know what you did my son!" he yelled, Alex stopping him just feet from Arizona.

Arizona snapped out of her trance and looked around. She saw the kids in the corner crying, Ben's mother hysterical on the floor, his father yelling at her and demanding answers. Then she saw Callie. When had Callie gotten there? And next to her a woman she vaguely recognized, though she could not place from where.

"Mr. Hendricks…I tried, I-I tried everything I could, he-he just…" Arizona said, trailing off.

"My son is dead," the father cried, leaning into Alex and letting his pain take over.

Arizona looked at Alex with guilt, pain, grief, a tornado of emotions swirling in her eyes. She couldn't be there anymore. She wouldn't be able to hold it together any longer than she already had. Alex immediately recognized this and looked over at Callie, trying to mentally tell her that she needed to get Arizona out of there. But before he could catch her eye, the woman he had just talked to, Ben's aunt, stood up and threw herself into Callie's arms.

Callie couldn't believe what was happening. The little boy that Arizona had performed surgery on was Brooke's nephew. She shouldn't be there. She needed to get Arizona and get out of the room. But before she could make a move, Brooke stood up and collapsed into her arms.

"Callie…my nephew is dead," she cried, burying her face into Callie's shoulder.

Arizona noticed Alex staring off in Callie's direction. She saw the woman she vaguely recognized fall into Callie's arms and upon seeing them together, she realized how she knew her…it was Callie's ex-girlfriend.

The weight she had been feeling on her chest increased to the point of excruciating pain when she saw Callie comforting her ex in her arms. She couldn't breathe. Her head got woozy and her knees began to buckle. She had to get out of there. She turned and ran through the door with only one destination in mind...she had to find the chief.

Alex sat Mr. Hendricks down and helped his wife into the seat next to him. The children gathered around their parents as they mourned. "I'm going to give you some privacy," he said. "But here's my number…if you need anything, if you decide you want to see him, just call."

The parents numbly shook their heads, taking the piece of paper and cradling their children in their arms.

"Dr. Torres?" Alex said. "We should let them have some time."

"Of course," Callie said, as Brooke finally pulled away.

"I'm so sorry Brooke," she said, walking her over to sit with her family.

"Thank you Callie," Brooke said, trying to smile as she sat down and took her sister's hand.

Alex grabbed Callie's arm and pulled her out of the room.

"What the hell was that?!" he yelled when they got into the hall.

"I know her," Callie said, not bothering to explain any further.

"Clearly but how? I mean…I feel for this family, I do. But Arizona should be your priority right now. She's barely holding it together. So who is this woman to you that you put her comfort over Arizona's?"

"I wasn't putting anybody's comfort over Arizona's!" Callie yelled, trying to defend herself. "I wasn't expecting to see her. I was caught off guard. I was surprised and I...I was just caught off guard."

Alex stared at Callie, trying to make the pieces fit when it hit him.

"That's her," he said.

"What?" Callie asked.

"The woman you dated after you and Arizona divorced. That's her isn't it?"

Callie didn't respond, she simply shook her head affirming his suspicions.

Alex turned around in disgust and began to walk away but Callie ran to catch up with him.

"What was I supposed to do Alex? Her nephew just died!" Callie tried to explain.

Alex stopped and looked at her incredulously.

"What were you supposed to do?" he asked. "You're supposed to hold your girlfriend, not some woman that you used to bang. You're supposed to comfort the woman who thinks she's the one that put that little boy in the morgue! She's falling apart and she had to see your ex-girlfriend in your arms!"

"I told you she caught me off guard. She's grieving. I couldn't just push her away," Callie said.

"You know who else is grieving? Arizona is grieving and now…she could be anywhere. So excuse me but I need to go find her!"

"Alex…let me. I need to talk to her. I need to make sure she's okay."

"No!" he yelled. "You've done enough! Just…get out of my sight."

And with that he walked away hoping that he would be able to find her in time. Because knowing Arizona…she was about to do something she would regret.
