A/N: So I decided to re-write the story – and remove as many of the spelling and grammar errors that I could find. The main storyline has stayed the same although it's no longer in first person as that's just irritating.

As Arizona pulls closed the ambulance door on Ruby and her distraught parents, she turns and looks at Callie looking upon her with those beautiful, soulful brown eyes. Arizona opens her mouth as she prepares to tell Callie that she's sorry for the hurtful words hurled at each other. But Arizona changes her mind as she can't articulate the words and instead, simply turns and walks away. Callie's shoulders slump in defeat as she realises that Arizona has nothing to say to her. Arizona has nothing to say to her about the fact that she yelled that she didn't trust her, that she was accused Callie of being in love with the concept of love rather than a person. Arizona was wrong, Callie thinks to herself as she replays the conservation in her head, but she's was too tired to fight, to convince Arizona otherwise. Callie is also a strong believer that you needed to trust someone to be in a relationship, but obviously Arizona didn't reciprocate this idea. Callie felt that their whole relationship was tainted with Arizona's idea that Callie's bisexual ways was going to rear its ugly head. That one day Callie would wake up and realise that she couldn't be with a woman and leave Arizona.

The adrenaline flooded out of Callie's body since confronting the shooter and she was exhausted, both physically and mentally. She slowly trudged back to her apartment, eager to fall into a deep sleep and pretend none of this happened. Just as she begin to drop off to sleep, a phone blears out the obnoxiously cheerful tone Arizona had picked for her ringtone weeks ago. It had been a joke tone as it really didn't suit Callie, but she was didn't have the heart to change it, holding onto whatever small part of Arizona she still had. Callie grabs her phone hoping that it was Arizona. Noticing the name of the screen, Callie answers and reassures her father that she is fine. Callie glazes over the actual details as he doesn't need to know that about the conversation she had with the gunman. Or had a gun pointed at her. As Callie ends the call and flops back on the bed, her phone immediately starts ringing again. The screen shows an unknown number and Callie cautiously answers with, 'Hello?'

'Callie, is that you?', the distinctive voice of Mrs O'Malley calls through the phone.

'Oh, hey Mrs O'Malley' Callie quickly responds, reassuring her that she's fine and no worse for wear. She questions Callie for a while about other doctors that George knew. Callie eventually convinces her that she doesn't need to make the trip into the city to see Callie or any of the other doctors. As she hangs up, Callie's mind drifts to George. Sweet, innocent George. Thinking about her ex-husband isn't a good train of thought for the already moody Callie, but she can't help but dwell on the fact that another of her relationships had failed. An idea forms in Callie's head and before she can talk herself out of it, she grab her car keys and head to the other side of town. Due to the time, Callie realises that the office may be shut. But she's in luck – from the street she can see the lights shining through the window. Callie knows what she's doing is impulsive and risky – but convincing herself that she need some time to herself without the interference from friends and family. If she leave Seattle, her father will track Callie down and force her to go to Miami. But here, she is definitely outside her father's grasp.

As Callie pushes open the wooden door, she sees a man in uniform sitting at the desk who looks up and says, 'Good afternoon Mame, can I help you?'

'Ah, yes, I want to enlist.' Callie fills him in on who she is, the fact that Callie is a surgeon causes him to become excited about the opportunities overseas.

'The military always has a shortage of medical personal, so the opportunities you would have would be endless. Due to the spread of personal at the moment, it's impossible to tell where you would be stationed. And how soon would you like to leave', to which Callie respond 'As soon as possible'.

With that he's on the phone to his commanding officer and within the hour Callie's told that she can leave within the week. He hands over a contract which Callie promptly signs without a second thought. Callie strongly believes that she needs to leave Seattle and at least by enlisting she would be doing some good. Living with Owen has opened her eyes to the severe shortage of good surgeons that the military suffers from. And Callie distinctly remember Arizona's words when she confronted her about George's enlistment, how her brother's death may have been prevented if more doctors were present. Although, Callie is trying to convince herself that she isn't doing this for that reason. Callie doesn't need for Arizona to be proud of her – well that's what she's going to keep telling herself. Once signed, he wishes Callie a good day and tells her that she reports for duty in two days.

Shoving the papers into her bag, Callie quickly return to her car and drive back to the apartment. Deep down, Callie knows that this is an impulsive, brash and down-right risky decision and probably not a good one. But Callie has convinced herself that she needs to leave Seattle. Arizona made that perfectly clear that there is no way for the two women to rebuild their shattered relationship. Callie also decides to tell no one about her plan as everyone is in pain at the moment, and her leaving to go to a war zone will just add to that. Everyone has way too much on their plate at the moment and Callie don't want to add to it. And she doesn't want an intervention or to be yelled at by Bailey for making an ill thought out decision.

Once back at her apartment, Callie starts writing her resignation letter to the hospital. She don't want to go into details of why and where she's am going – so short and sweet it is. As Derek has been shot, she's not sure who to address the letter to – and simply says;

To whom it may concern,

Due to unforeseeable circumstances, I am unable to continue my employment at Seattle Grace Mercy Hospital. I am sorry if this causes an inconvenience for the department but I feel I would no longer be an asset to the hospital. I apologise for the abruptness of this notice in light of the current situation.

Yours sincerely,

Dr. Calliope Torres

With that, Callie print it, sign it and place it on her desk. Feeling nothing more can be achieved tonight, Callie turn in and hope tomorrow will be better day.

Waking up the next morning to the sound of her ringtone, Callie briefly converses with Christina who tells her to bring clothes and food to Seattle Presbyterian Hospital where all the injured were taken. As Callie wants to see them all before she leave, Callie collects the gear and heads over. Catching up with friends helps, conversation is limited as no one really knows what to say to each other. Callie retells her confrontation with the gunman to several people, including the police. But she doesn't even catch a glimpse of Arizona. Callie briefly wonders if she's avoiding her, but then again, Callie's pretty sure she's also in the avoidance stage. Callie wouldn't want to blurt out that she's enlisted and for Arizona to not to care, to simply shrug her shoulders and walk away. Keeping to the decision that Callie made last night she doesn't tell anyone of her impending departure. Deep down, Callie knows that her decision could backfire but she craves a clean break from Arizona

Spending the day at the hospital causes mixed feelings. Physically everyone is expected to make a full recovery. Alex is awake, Derek is sleeping off the aesthetic and Owen is awake and loopy on pain killers. But emotional, everyone is a mess. Owen is telling Christiania how much he loves her, that he loves her more than Teddy. Lexie is sitting at Alex's bedside while Mark watches on. Alex has already told Lexie to piss off which caused Mark and Alex to get into a yelling match. And Meredith is trying to come up with a way to tell Derek that she had a miscarriage. Callie begins to feel that she can't deal with all the drama, she needs to leave. Saying her goodbyes she assure them she'll be back tomorrow. A small white lie to save face as Callie report for duty tomorrow it 8am. Cementing the faces that she have grown to love in her mind, Callie turns and walks away.

Returning to her empty apartment, Callie surveys the emptiness of her life. Her bedroom is impersonalised – no photos as they had all been some type of reminder of Arizona. Her face adorned so many of them – that Callie had simply picked them all up and thrown them in the back of her cupboard. Setting her alarm for early tomorrow morning, she hopes and prays that she has made the right decision. Turning in, Callie sees the small bag of personal items that she is allowed to take with her. That's all what her life is now, one small bag of moments. Sighing, she closes her eyes and pray sleep takes her to better place.

Before Callie leaves the apartment the next morning, she quickly jots down a note to Mark explaining where she will be for the next several months. Callie doesn't try and explain her decision because she can't. He'll think Callie is being impulsive, brash and stupid. But Callie has all but convinced herself that she needs to leave, that she can't return to work and see her. Carrying the letter, her resignation and a small number of personal belongings Callie closes the apartment door behind her and life as she knows it. Slipping the note under Mark's door, Callie hopes that he accepts her decision. Callie heads over to the hospital to formally resign from her position. Luckily, it's so early that she simply drops the letter with all over paperwork that the Chief needs to look at. And with that, she turns and walks out of the hospital and attempts to start her life again.

'She what?' exclaims Christina.

'Enlisted, she left yesterday.' Mark replies grasping Callie's short note in his hand. Mark hadn't returned to his apartment yesterday and so he hadn't been aware of the decision that Callie had just made. He'd tried multiple times to call Callie yesterday, but it kept going straight to voicemail. Mark had figured Callie was just avoiding everyone over her split with Robbins. But she had been flying half way around the world to get herself killed. And now, she was gone. Mark hands Christina the letter and she quickly scans what Callie had written.

'Didn't she remember the intervention that SHE organised to stop George from going. And then she proceeds to enlist herself. And now – of all the times to do it. And does she know?'

Mark immediately clues on to 'who' Christina is talking about - Arizona Robbins, the women who broke Callie's heart which resulted in Callie making the stupidest decision of her life. The last time Mark had seen Torres she had mumbled that her and Blondie had fought during the lockdown and insults and cheap jabs had been made to get a reaction. Callie had indicated that whatever chance the two women had at getting back together was gone. Mark realises that he needs to tell Robbins before the gossip mill gets a hold of this story – without getting killed in the process. Callie ran away from her problems in the most drastic way possible. Both surgeons begin to search the hospital hoping to track down the elusive blonde. Spotting Arizona up ahead reading a patient's chart, both surgeons approach her. Arizona oblivious to their approach, continues to read. Finally glancing up she sees them and before they even start talking.

'I don't want to talk about it. This is between Calliope and I.'

'Ah, she told you?'

'Told me, I was there when we broke up. So stay out of this Sloan. I know it's hard to believe this, but I really don't need you interfering in my relationship any more than you have been.' Arizona snaps out as she heads away from Mark. 'I'm sure you to have better things to do than tell me what an evil misguided person I am for breaking her heart.'

'It's not about that, well it kind of is. But look just read this.' Yang says as she hands the note to Arizona. Glancing at the handwritten note in her hand, Arizona begins to read and feels her heart plummet.

Mark,

I have to go. I can't stay. I need to go. So I'm leaving, I've enlisted and I report for duty today. Please, be ok with this. I will come back. Callie

Once Arizona's finished reading, she simply stands there in shock. Callie's gone, she enlisted – of all the things she did. She enlisted.

'Mark…' Arizona begins to stutter out as all the colour drains from her face, her blue eyes begins to shine with tears. With that, Mark pulls Arizona into his arms as she begins to sob uncontrollably. The emotions of the last several days finally catching up with her. Callie Torres was gone.
