The next morning Erica Hahn walked into Seattle Grace. As she walked the familiar hallways images of Callie and Sloan , Callie defending Izzie and the hospital started to flood her mind but she quickly pushed them away. She was here to save somebody's life and that's what she would do. If she found closure in the process that was an added bonus.

As she walked towards the nurses station she saw Mark and Cristina standing there. Their eyes widened in shock once they saw her. Mark looked annoyed " What are you doing here? Didn't you do enough damage by leaving that you are back here now"

Erica smirked " Sloan , I don't need your permission to be anywhere. But since you asked Callie called me for a consult on Dr. Robbins case". " Now if you don't mind I have to go and prepare for the surgery and have a look at the chart".

Cristina stopped her "Callie called you to perform Arizona's surgery". "Brilliant deduction ,Yang. I might even let you scrub in on the surgery." Erica walked off.

Erica dialed Callie's number and said "Callie , I am here at the nurses station". As Callie approached Erica at the nurses station she was experiencing a myriad of emotions relief, akwardness , anger but all she said was " Hi Erica. Thanks for coming". Erica just nodded " Lets go save Dr. Robbins. We can talk later".

Erica looked over Arizona's chart and decided they needed to do the surgery that day. She chose Owen , Bailey and Cristina to scrub in with her on the surgery. Bailey and Cristina did not like Hahn at all but they recognized that they all needed to work together to save Arizona's life so they decided to be as cooperative as possible.

As they were scrubbing in for the surgery , Callie entered the scrub room and approached them " Thank you once again, Erica". "Don't thank me now, thank me once she is alright" Erica said before entering the OR. Callie approached Cristina "Take care of Arizona for me". " I will" she said before she too entered the OR.

It was a six hour surgery and it was torture for Callie who was sitting in the gallery watching. Mark approached her with a cup of coffee. Callie nodded her thanks as he sat down next to her.

" I still cant believe you called her" he started. " It was the best thing to do. She's the only one I could trust with this surgery" she explained. "But doesn't this make things complicated for you Callie? You and Erica never even said goodbye". "Mark , that's the last thing on my mind right now. Right now all I care about is getting Arizona through this" said Callie with a determined expression on her face.

Once the surgery was over Erica approached Callie who was waiting with bated breath for the news. " Congratulations Callie , the surgery was a success. We were able to repair whatever damage had occurred to her heart tissue. The pressure on the brain is still an issue which Shepherd will handle but her heart is fine".

Callie felt tears of relief pouring down her cheeks. She knew they weren't out of the woods yet but this was a huge step in the right direction. She was brought out of her thoughts by Erica asking " Are you free at nine tonight. Lets meet at the Archfield lobby. I think we need to talk". Callie nodded and Erica walked off.

Callie suddenly felt a tap on her shoulder. She turned around and when she saw who it was she gave them a huge hug " Mrs. O' Malley, When did you get here? I am so sorry about George". Mrs.O' Malley replied " George's surgeries were a success Callie. He has a long way to go but for now he's fine. He's still very weak but he wants to speak to you".

Callie entered George's room and as soon as she saw him alive and awake she felt more alive than she had in these three dreadful days. She walked upto his bed and whispered "Hi George"

George managed to croak out " Callie , I need you to listen to me without interrupting . I know I broke you when I slept with Izzie and when I didn't try to fight for our marriage even though you wanted to. I never properly apologized to you for that. Despite that , in the last few months you have been an incredible friend and supported me when my other friends had even forgotten I existed. You are an incredible woman Callie and you should be happy. I don't want you to ever blame yourself for what happened between us. After the accident as I was laying on this bed ,all I could think about is that my girls should be happy. Promise me Callie , that you will be happy. is an amazing person , promise me you wont close your heart to love just because I broke it".

Callie left George's room with tears rolling down her cheeks but she also felt a lightness in her chest. She and George had finally communicated what all they had felt in the past year and they could now finally be good friends.

Bailey moved briskly out of the room in search of Dr. Shepherd. After a few minutes of tracking down, she finally found him at the Nurse Station on the 4th floor, focused on scribbling notes on a patient's chart.

"Good evening, Dr. Shepherd," Bailey greeted, walking towards the station.

Shepherd looked up and nodded. "Dr. Bailey," he acknowledged. "How's Dr. Robbins?"

Bailey shook her head, sadly. "Heart surgery was a success but she still hasn't woken up. No changes on pressure on the brain" she stated, quietly.

Shepherd sighed and went back to scribbling on the chart. "I'm getting her into the OR tomorrow morning. If we're going to do that surgery, we would have to do it soon," he said. "Do you think you can schedule that for me?"

Bailey nodded almost immediately. "Of course, Dr. Shepherd." She started to walk off, but then stopped when she realized something. She turned back to Shepherd and asked cautiously, "What if there are...changes?"

Derek looked back up at her, knowing immediately what she meant and managed a weak smile, "If Arizona wakes up before we get her into the surgery and shows signs of recovery, then cancel it."

As Callie approached Erica in the hotel lobby , she was feeling anxious but also relieved that they could finally talk because she had missed talking to Erica.

Erica smiled "You are here alone. I thought Sloan would have been here with you".

Callie replied " Erica, Mark is just my best friend"

" Oh so you sleep with all your male best friends" Erica questioned.

Callie said with an earnest expression "Erica , I will always regret hurting you. I never meant to do that , its just I was confused and I slept with Mark to try and find some answers not realizing how much I was hurting you. I really am sorry because that was the day I really hurt my best friend".

Erica gave a small smile " It wasn't all your fault Callie. I shouldn't have lied to you and said it was ok when it wasn't . I shouldn't have used Izzie Stevens as an excuse to run away from you just because I felt I was falling much faster than you were. I made mistakes too Callie"

Erica continued " I want to put that bitterness behind us. I am learning to be happy and for the last 2 months I am dating this nice woman. Her name is Kelly and she is a neuro surgeon. I just want you to know that I want you to be happy Callie. You deserve to be happy Callie"

Callie had tears in her eyes " Can I have my friend back. I have really missed her."

Erica answered with a smile " You have her Cal. She missed you too"

Callie and Erica hugged each other grateful that they could salvage their friendship even after the mistakes they had made.

Erica smiled " So tell me about Dr. Robbins"

Callie started " Arizona is my girlfriend. She picked me up and brought me back to life after you left. She is perky and happy most of the time but there is a serious side to her that a lot of people don't see. She doesn't let merun and makes me communicate with her. She stays there with me even when
I try to push her away. "I just want a chance to apologize for being an idiot and tell her how I feel".

Erica smiled " I realized she was someone important to you because for her you ignored the akwardness and called me. I could sense the pain in your voice when you spoke of her being hurt. I hope you two find happiness together".

As Callie walked back to the hospital she felt as though a huge weight had lifted off her chest. She had found closure with George and Erica today and she was starting afresh as friends with both of them. For the first time in months Callie was looking forward to her future.

With a burst of amazing clarity Callie now knew that she wanted to move forward and the person she wanted by her side was Arizona. She now just prayed that Arizona woke up so she could tell her how she felt about her and that Arizona was her future.
