Author's Note: A few things to note Arizona arrived at the beginning of season 4 not season 5. Takes place at the beginning of season 7. Arizona never went to Africa so Callie and Arizona never broke up. So Callie never got pregnant with Sofia. I plan on writing Sofia into the story later on. Let me know what you think. I hope you enjoy.

Arizona' POV

6:45am. I hear the alarm going off and shut it off. I check my phone and realized the date. Shit. One of my two least favorite days of the year. 8 years ago today I made a decision that I have regretted everyday since. I wish I could go back in time and change that decision but I can't.

As I sit up Callie pulls me back down and says, "Where do you think your going?" She kissed me and I pull away and say, "Not today, I have busy day and I can't be late." I realized after I said it how harsh that sounded.

Callie replies, "Okay well do you have time for breakfast or coffee?"

I reply, "Not really I have to shower and leave so I am not late." I grab my stuff and am about to head into the bathroom when Callie stops me.

Callie looks at me and says, "What's going on Arizona? Every year for the past two years on this day you aren't you happy perky self instead you are cranky and you shut yourself off. I know it doesn't have anything to do with Tim because it isn't the day he died or his birthday. You tell me everything Arizona. So what is it?"

I am stunned. I want to tell her. But how will she ever look at me the same. Will she love me? I can't have her leave me. I need her. But if I don't tell her I risk losing her. I need time before I tell her the truth.

I reply, "You're right there is one thing about this day that I hate. And I will tell you just not right now. Like I said I have busy day and if I am late I will never get out until tomorrow. So I promise to tell you tonight over dinner. Okay? I love you!"

Callie replies "Okay but you're telling me tonight and I love you too."

A few hours later

Owen's POV

10:45am.

Incoming trauma. MVC accident. Car vs. tractor-trailer. 3 victims.

The ambulances roll up. First ambulance truck driver minor injuries.

Second ambulance 8year old female trauma to the head and wrist I have Karev take her to trauma 1. And have him page Torres and Shepherd.

Third ambulance rolls up. Woman late 40s.

Dave the paramedic turns to me and says, "She is tachycardic, multiple fractures, obvious head and chest injuries. Her BP is 180 over 95. Her husband was DOA (dead on arrival) at the scene the 8 year old brought in is her daughter Lily. They were on their way here when the truck ran through a red light and hit them. From what I understand they were on their way to this hospital when the accident happened. Lily hasn't been feeling well and woke up with weird bruising on her back. The mother asked me to have someone page Dr. Arizona Robbins apparently they know each other. She also gave me this (he hands me an envelope). She said if anything happens to her to make sure that someone gave this to Robbins."

I reply "Okay, thanks."

I look at Meredith page Altman, Shepherd, and Robbins. Maybe Robbins can give us some history. And let's get her into trauma 2. As soon as we pull into the trauma room she flat lines so I start running the code.

Arizona's POV

11am.

I was paged to trauma 2. When I arrive Hunt called out "time of death 11am." I notice a women in her 40s so I am confused as to why I was paged after all I am a pediatric surgeon. I look at Hunt and Altman and say "Owen, Teddy what's going on why was I paged she is clearly not a child?"

Hunt replied "The patient Karen Baker was in car accident with her husband who was dead on the scene and her 8 year old daughter Lily who is in trauma 1 with Karev. She told paramedics to have someone a page you and if she passed away she said to give you this (he handed me a letter). Teddy looks at me and asks "How do you two know each other?"

I tense hearing those names. Those names Karen Baker and Lily how could I forget. I can't believe this is happening. Then I think Oh my god Lily! I ignore Teddy's question and I run across the hall into trauma 1. I find it empty. I run out into the ER looking for Karev. I can't find him anywhere. I feel like my head is spinning in circles. I feel a hand on my should I jump it's Owen.

He says "Arizona what's going on?" I ignore his question and say "I need to find out where Karev is, where Lily is!"

Teddy replies "Sheperd, Karev, and Bailey took her into OR 3 about 2 minutes after you came into trauma 2, she has subdural hematoma and some internal bleeding. She also has a broken arm that Torres had to set and put in a cast, Grey just texted me with an update."

I start to cry and run out of the ER to head the OR when Hunt grabs my arm to stop me and pulls me into trauma 1 and Teddy follows us.

He looks at me and says "Arizona what is going on? How do you know these people?"

I reply "Okay, I will tell you but you two have to swear you will tell no one until I tell Callie!" They both promised not to tell.

I say "Okay 8 years ago today I gave birth to a beautiful baby girl and gave her up for adoption. Karen and Joshua Baker are my daughter's adoptive parents. So Lily is my biological daughter. I have regretted my decision to give her everyday for the past 8 years. Now she is in the OR! What if she dies and I never get to meet her?" I start to cry.

Owen pulls me into his arms and tries to soothe me.

Teddy takes me in her arms says "Oh my god Arizona I am so sorry. But, hey she has some of the best doctors she will be okay. Why don't we go to conference room and read the letter. Then we will page Callie. Okay?" I reply okay and with that we head to the conference room.

Author's Note: Let me know what you think and what you want to have see happen. I will be updating shortly. Next Chapter, Arizona reads the letter, tells Callie, finds out about why Lily was coming to the hospital, and maybe just maybe she will meet Lily. So, you will have to read to find out. Please Review :)
