A/N: Ok, firstly sorry about the wait. Hope the majority of you are still with me, this story is drawing to a close but I'm definitely thinking of a sequel. To those that think Arizona is always the one getting the attention, that's not how I intend to write it, the storyline with Joanne isn't about her being Arizona's interest it's more about bringing back the past and where that leads to. Anyhoo onwards we go.

Credit and muchos thanks and love to sexshaw for creative input when I'd hit a brick wall and for beta-ing

Arizona's eyes went wide, it couldn't be? Not here, not now, 'Joanne?'

'Arizona,' the other woman greeted slyly.

'You two know each other?' Clara asked, confused. Callie however was far from confused; she knew exactly who Joanne was and was finding it insanely difficult to not beat the crap out of a woman she had only just met.

'Arizona and I used to...'

'Work together.' Arizona finished, finality in her tone. Turning to Clara she spoke exclusively to her, 'Denver has come through the operation well, he's just in recovery now, you can see him shortly when he's a bit more orientated.' Turning on her heel Arizona walked quickly in the direction of her office, her mind going one hundred miles a minute as she took in the fact that Joanne was stood on the yard.

'Arizona, wait!' Joanne's voice sounded as she started to follow her. Arizona ignored the shout, her pacing quickening. As Joanne moved to follow her, she felt an arm stop her.

'I don't think so,' Callie said, her voice a lot calmer than she actually was.

'Excuse me?' Joanne retorted before realisation dawned on her. 'Ohhh I get it, you're the latest shag right?'

'I think you'd better leave.' Callie replied, her grip tightening, 'You don't have any business being here.'

'You can't throw me off of the yard!'

'Oh you don't want to push this,' Callie replied, shoving Joanne in the direction of the yard gate. 'Mrs Roberts you're welcome to stay in the waiting room but we'd appreciate it if she wasn't there too.'

'I'm here to support Clara, I'm not going anywhere.' Joanne replied, any excuse to stay and cause any trouble she could for Arizona Robbins.

'Jo, maybe you should just go?' Clara interrupted. 'My main concern here is Denver, and I don't know what's gone on between you and Dr. Robbins, but right now the fate of my horse is in her hands so I'd rather her not be distracted in the slightest.'

Jo just smiled wickedly, 'I'll make myself scarce for now, but I want to speak to Arizona...I'd say we have unfinished business...'

'What do you mean?' Callie asked, taken aback my Jo's words.

Jo just smiled, 'I'm guessing she hasn't told you everything about us...go and ask her...she won't seem so perfect when she tells you the full story.'

'I know the full story.' Callie said, trying to hide the doubt that was now creeping into her mind.

'Do you?' Jo asked. 'I bet she told you how I told everyone that she forced herself on me, nearly ruined her career, blah blah blah...but I'm guessing she missed out the part that happened after that...'

'She got a job here.' Callie interrupted.

'I mean before that,' Jo said. 'She won't have told you that part...so before you start judging me you go and ask her what happened...then come back and tell me she's still the woman of your dreams.'

'Just get off the yard,' Callie said as she turned on her heel.

'Ask her who left who,' Jo called after a retreating Callie. 'Ask her about the ring.'

Joanne's words had Callie pausing for a split second, what was she talking about? Shaking her head, Callie ignored the other woman and headed straight for Arizona's office, she didn't want to believe a word that came out of the nurses' mouth, but her statements were niggling at the back of Callie's head. Ring? What did that mean?

Knocking softly on Arizona's office door, Callie pushed the door open finding Arizona on the couch, her eyes fixed on a point on the wall. 'Well that was...intense.' Callie said wanting to break the silence. When Arizona didn't show any response to her, Callie moved further into the office shutting the door behind her. 'Zo? What can I do?'

Arizona looked up at Callie for the first time, she loved this woman with all her heart, but right now she needed to be alone. She needed time to process, that's how she has always done things, particularly when faced with a particularly tricky situation, much like this. 'I just...I need a minute? Can you just go and keep an eye on Denver?'

Callie was taken aback, 'I want to keep an eye on you...well, make sure you're ok.'

'I'm fine...I just need a minute to process this...'

'Process what?' Callie asked, she wasn't trying to be awkward but she needed to know what Joanne had been implying with what she said.

Arizona's eyes shot up to meet Callie's, 'To process the fact that Joanne is out there stood on the yard as large as fucking life.'

Callie nodded, 'I get that it's a shock...but why does it bother you this much Zo? I thought this was all your past now?'

'It is!' Arizona said, angry that Callie was asking stupid questions. 'But having her show up totally out of the blue is a bit of a fucking shock so excuse me if I just need a minute to collect my thoughts.'

Callie took Arizona in for a minute, although they'd only been together for nearly a year, she knew Arizona and she could tell when she was upset. But sat on the couch Arizona wasn't that at all; if anything, she was nervous? What was she nervous about? Callie thought about leaving, thought about just turning around and leaving Arizona to 'process' or whatever, but Joanne's words had, rightly or wrongly, had hit a nerve. 'Joanne said you hadn't told me the full story...'

Arizona's head shot up once more, 'Oh and you're believing her over me now?'

'I wasn't,' Callie replied. 'That was until I came in here and saw you like this.'

'Like what?!'

'Jumpy, nervous...it's like you're scared that something's going to come out...is there something I don't know here Arizona?' Callie asked, she could feel the emotion welling up in her, the tears building in anticipation for every eventuality that could escape from those perfect lips.

'There's nothing else to tell,' Arizona said, sighing as she looked back down to her hands.

'You're lying.' Callie replied simply, it wasn't an accusation, it was a fact; Arizona was avoiding looking her in the eye, her hands were fidgeting against each other; she was bare faced lying to Callie and she had no idea why. 'Please can you just be honest with me here because my mind is running away here...'

Arizona just shook her head, 'There's nothing else to say Callie.'

'Nothing about a ring?' Callie asked, remembering what Joanne had just said to her.

Arizona couldn't hide her shock at that statement, her eyes going wide as her hands stilled in front of her, shit. 'What?' She asked, conviction not reaching her voice.

'Joanne said that I should ask you about who left whom and about a ring...I thought she was just spouting crap, but now I see that I was wrong...' Callie stopped, tears now escaping her even though she hadn't heard Arizona explain herself.

Arizona shook her head, 'I can't do this...'

'Can't or won't?' Callie shot back, anger filtering in through the fear and tears.

'I can't believe she's fucking done this...I swear I'm going to kill her,' Arizona said, suddenly rising to her feet and making for the door.

'Oh no, no, no.' Callie said, stepping in between the door and Arizona, 'You need to tell me what the fuck is going on here Arizona.'

Arizona sighed, rubbing her forehead with her hand, 'You'll hate me.'

'What?' Callie asked, taken aback by the now softness of Arizona's voice.

'There's a reason I haven't told you...told you what Joanne's talking about.'

'So there is something you've been keeping from me?' Callie asked, although she had suspected when she saw how Arizona was acting, actually hearing the confirmation of the fact crushed her.

Arizona just nodded, 'If I'd have told you, you would have walked away Callie...you would've walked away before we'd even begun...and then we got started and I thought about telling you, I really did...but the more I fell in love with you, the more I realised I'd never be able to tell you, I knew that if I did you'd...you'd think of me as a monster...'

Callie stood, slightly shocked at Arizona's words, 'What is it?'

Arizona sighed, slumping back down on the couch, 'I told you that Jo came clean but it was never the same at the practice and then I got the job offer here and just left with Karev...'

'Yeah?' Callie asked, remaining where she was, not trusting herself to move.

'That's only partly true,' Arizona said. 'It was hell afterwards but not just for me...Jo begged me for another chance, begged me to take her back...and I did.'

'What?!' Callie gasped in shock. 'I thought you...'

'I loved her Callie!' Arizona interrupted, 'Yeah she screwed up but I loved her...I thought I did anyway...I was so cut up about Tim, I just needed someone to lean on...I needed someone to be there for me and Jo was offering that...we were together for another couple of months...she was amazing honestly through those two months...she looked after me more than she ever had before, told me that she was going to prove just how much she loved me and how wrong she had been to do what she did...and she did...she asked me to marry her.'

Callie could've sworn her stomach fell through the floor at that admission from Arizona, here she was thinking of doing the exact same thing herself and now she discovers that Arizona was what? Already engaged? 'Oh my God are you married?!'

'What?! NO!' Arizona said in shock, 'Calliope I could never do that to you...'

'Well you seem to have been quite capable of lying to me this far...'

'To protect you!' Arizona shot back, her eyes now betraying tears herself.

'So you said no?' Callie asked, Arizona shook her head. 'You said yes?'

Arizona nodded, 'I said yes, she stuck a ring on my finger and called me her fiancée. Then the offer came in from here and I just...I wanted this job so badly...for my career, for me...Everyone in that practice disrespected me, no one listened to me and no one gave me a chance to experiment or prove what I could do...but I knew that Jo loved it there...I knew that I couldn't ask her to move...so I left.' Arizona said, resting her head in her hands.

'You left?' Callie confirmed.

Arizona nodded, 'I left a note saying 'I'm sorry' with the ring on the table and was gone.'

Callie felt like the wind had been completely knocked out of her, she'd felt like this once before, when she'd been told that Arizona was dead. Although she was sat before her, very much alive, Callie felt like she didn't know the person sitting before her at all.

Arizona looked up from her hands, tear stains on her own cheeks mirroring those on Callie's, 'I'm sorry.'

Callie shook her head, 'I can't believe this...so what does this make me Arizona? The fucking rebound?'

'No!' Arizona said, once more leaping to her feet. 'Callie I love you...'

'You just said that you love her!'

'Loved!' Arizona shouted. 'I did love her...I thought she was the one, then I met you and none of the rest of it mattered anymore.'

'If it didn't matter then why didn't you tell me?' Callie asked.

'Because of this! Look at how you're reacting...'

'Oh no, you do not get to turn this around on me! I'm reacting like this now because we've been together for a year Arizona, we've been to hell and back really and all this time you've been lying to me? Fine, I would have been shocked if you'd have told me this that night when you told me the other stuff about your past...but that's it, I would have been shocked. I wouldn't feel like this...I wouldn't feel this hurt.'

'Calliope...'

'No, you do not get to Calliope me here Arizona. This is...so not ok!'

'You don't think I don't know that?!' Arizona shot back. 'You think I'm proud of what I did?'

'I don't know Arizona are you?' Callie said, her hands gesturing in front of her. 'Is this what you do? Move from practice to practice making girls fall in love with you at every one? Making them fall in love with you so hard that they want to give you a ring and ask you to spend the rest of their life with them?!'

Arizona rolled her eyes, 'Joanne is the only one that's ever even thought about marriage...'

'No she's not.' Callie interrupted, her voice quiet now and breaking slightly with emotion.

'What?' Arizona asked confused.

'She's not the only one that's ever thought about marriage.' Callie replied, making it very clear what she meant.

Arizona's mouth opened and closed, words failed her; of course she'd thought about spending the rest of her life with Callie; but she hadn't realised that Callie had been sharing those thoughts, let alone going that one step further. 'Cal...'

Callie just shook her head, 'I'm going to stay at Mark's tonight.'

'Callie, no, please...can we just talk...' Arizona tried to move forwards but Callie just stepped back away from her.

'I think there's been enough talking for now,' Callie replied. 'Come on Jasp..' Jasper trotted to Callie's heel, following her out as she left Arizona's office, shutting the door behind her.

Arizona sighed, reaching out she went to follow Callie but then stopped, making a scene in the middle of the yard wasn't going to fix this. Flopping down onto the couch she reached forwards, grabbing the nearest thing to hand she flung the tissue box across the room. 'Fuck, fuck, fuck, fuck.' Running her hands through her hair she found Dotz and Harry sat looking at her expectantly. 'Oh guys, I've really fucked things up this time.'

Arizona didn't know how long she sat in her office staring at the door, time didn't seem to matter as she sat there replaying the events in her mind. Things had gone from being pretty much perfect to horrifically awful in the blink of an eye, and as much as Arizona wanted to blame Joanne for that, she knew that it was also very much her own fault. She'd made the choice to keep that part of her life from Callie and now look where it had left her. Part of her didn't know why she'd kept the engagement and her subsequent running from Callie; she'd been so scared to lose her before she'd even got her. Even right at the beginning, Arizona had known that Calliope Torres was something special, something very different. As a result, she'd kept the true ending of her and Jo from Callie and now karma had well and truly bit her in the ass.

Looking to the clock, Arizona realised she had been sat in her office for nearly an hour and whether she liked it or not, she had to check on Denver. Pushing herself to her feet, Arizona checked herself in the mirror, splashing some water on her face to try and get rid of some of the redness. 'Come on you two,' Arizona said, feeling she needed the dogs so at least she had someone on her side. Throwing the door open, Arizona was initially relieved to find the yard empty, glancing over to the car park she saw that Callie's 4x4 was gone. Turning away she headed over towards the OR, shoving her hands in her pockets as the cold hit her.

'Arizona!'

Arizona rolled her eyes as Joanne's voice reached her, 'Seriously?!'

'Arizona, wait!' Joanne continued to call, jogging forwards so she now stood next to Arizona. 'Come on, you have to admit that you owe me a couple of minutes at least.'

Stopping Arizona pointed a finger directly at Joanne, 'After what you've just done, I don't owe you shit Joanne.'

'After what I've just done?! I think you'll find that you brought it all on yourself.'

'Look, I really don't want to do this, just go back home Jo.' Arizona said.

'Just tell me why.' Jo said, her voice not filled with anger, but with desperation. 'I need to know why.'

Arizona sighed, 'I couldn't pull you away from your home Jo, the practice may have been a shithole to me but you loved it there...'

'But I loved you more!'

'Well you had a funny way of showing it!'

'I asked you to fucking marry me Arizona, was that not proof enough?'

'Exactly,' Arizona said. 'You asked me to marry you to prove a point...that's not a good reason to get married Jo...you have to admit that...I got the job offer here...it was a way out...I'll admit it ok? I bailed, I used the job here as an excuse to get out of telling you that I'd made a mistake...get out of telling you that I didn't want to marry you.'

Joanne scoffed, 'Gee thanks.'

Arizona shook her head with a sigh, 'Look Jo, I am sorry ok? I'm sorry for the way I left you, but I'm not sorry that I left you...I'm not sorry that I came here...'

'Because of her?'

'Partly,' Arizona said. 'Mostly...she's my life now Jo...if I haven't screwed things up...'

'You never loved me like you obviously love her,' Jo admitted; seeing the way they looked at each other even during the heated moment earlier and now hearing how Arizona talked about Callie confirming this fact.

Arizona offered a sad smile, 'I did love you Jo...but...'

'Not enough.' Jo finished for her.

Arizona nodded, 'Are you and Mrs. Roberts a thing?'

Joanne sighed, 'We were...I went out to see them for a birthing of one of the mares, her and me hit it off straight away...but she's married and...you know...sophisticated or something like that...we could never be anything serious.'

Arizona shrugged, 'I don't know...her and her husband broke up...'

'Really?' Jo asked, trying and failing to hide her true interest in Clara.

Arizona nodded, 'That's what she said anyway.'

'She'll never properly leave him,' Jo replied. 'Well...she'd never leave his money.'

'That's a bit harsh.'

'It's true,' Jo replied. 'Why would she live him and his money...the life he can provide for me?'

'Because I love you.' Clara's voice interrupted the conversation.

Both Arizona and Jo whipping their heads round to the new voice, 'I'm going to check on Denver.' Arizona said offering a smile to both women as she left them to sort out issues they obviously needed to.

Pushing open the door to the OR, she found Lexie and Alex sat on the OR floor, Denver still in the crush, whinnying slightly when Arizona entered the room.

'Hey boss.'

'How is he?' Arizona asked.

'He's good, bps normal, he's taken a handful of oats and he's being a very calm lad.'

Arizona smiled, 'Good.'

'You ok Arizona?' Lexie asked, noticing the rawness on Arizona's face.

Arizona just nodded, her emotions threatening to get the better of her.

'Robbins?' Karev prompted, the brotherly protectiveness he had for his boss coming to the fore.

'Jo's here.' Arizona said simply.

'What?!' Karev responded, instantly jumping to his feet.

Arizona sighed and proceeded to give Alex the rundown of what had happened since Denver's surgery, filling Lexie in when needed, to explain the events at their previous practice.

'So what now?' Alex asked.

'I find some way to get Callie to forgive me,' Arizona said, resting her head in her hands once more as she sat on the OR floor opposite Karev and Lexie.

'You got any idea how?' Alex asked.

'Well for a start, I need Lexie to tell me where Mark's apartment is...after that I have no idea,' Arizona admitted. 'All I know is that I love her more than...anything and I'd give her the world...I just need to find a way to show her that.'
