"While you were in Africa, I slept with Mark."

The phrase repeated over and over inside Arizona's head. She slept with Mark. Her Calliope, the love of her life had slept with Mark.

"Arizona?"

"I'm supposed to change for you? Why, because we're in love? I mean because you fall in love all the time with men, women…"

"Ok, fine I don't want to go to Africa ok? But I DO want to be with you, so I'm really trying here… No! NO! Please! Please, I can, we can, we can do this, we can, we can figure this out! ... If you get on that plane, if you go without me we are DONE you hear me? We are over!"

"We are standing in the middle of an airport screaming at each other; we're already over."

"Arizona?"

Callie watched Arizona as the confession she'd just made slowly registered in her mind. She was frozen solid, mouth slightly open. The frightened look on her face disappeared as her face slowly fell. The look in her eyes darkened, her gaze slowly lowered. Callie wanted her to say something, a reaction, any reaction was better than this. Arizona was now staring off into space and seemed like she had entered a catatonic state and it didn't look like she'd be coming out of it anytime soon.

You know I love you Arizona, and it is because I love you that I'm writing this to you. You're miserable, Callie is miserable. You need to get back here and fix this. You're being an idiot. You love each other. You deserve each other. Do whatever you need to do, but come home! Teddy had written this in one of the many e-mails she and Arizona had exchanged during her short time in Africa which apparently, hadn't been short enough.

"Arizona!"

Arizona was snapped back into reality when Callie yelled out her name. It took her a few moments to finally find her voice. When she spoke, it barely came out in a whisper.

"You slept with him?"

"Arizona…" Callie began, wishing she would just look at her. Arizona had remained looking down, refusing to make eye contact.

"When?"

"What?" Callie asked. Arizona's question had been inaudible and had not reached Callie's ears.

Arizona looked up at her. It looked like she'd aged 10 years in the last 10 minutes. Callie could tell she was trying to stay in control of herself but was failing miserably. Tears filled her eyes, those beautiful blue eyes which now held so many emotions. Callie could feel the anger vibrating off Arizona's body, but what she saw deep within those eyes was nothing but immense pain.

"I want to know when you slept with him. I want to know how long I was gone before you decided it was alright to jump into bed and screw each other's brains out. Did you even wait until I was gone, or has this been going on for longer?"

"Arizona, how can you ask that? How can you think I would've been capable of cheating on you?"

"Don't avoid the question Callie. How can I NOT think this has been going on longer? I was gone for less than 2 months! We were together for 2 years, we were in love, or at least I thought we were. If you really love someone, would you really have sex with someone else so soon? And MARK, of all people, why MARK?"

"I never cheated on you! You're the one that left me standing in an airport, remember? You were going to be gone for 3 years. You BROKE UP with me. I didn't think I was going to ever see you again. You have to let me explain this Ariz-" Callie said as she tried to reach over and place her hand on Arizona's.

"No! Don't touch me! I can't stand you touching me right now."

"Arizona please let me explain." Callie's voice had reached desperation, her eyes too, began filling with tears.

"What is there to explain Callie? You're right, I left. I left and you had sex with Mark. That seems pretty self-explanatory to me."

"But it's not. Arizona I love you…"

"How could you say that to me now? After everything you've said, how can you tell me you love me? How could you do this? Why am I here? Why did you bring me here? Was it so that you could torture me with this knowing I'm stuck here and I have no place to go?"

"No, that is not the reason I said this. I didn't want to keep this from you any longer. I love you, and I want you, I want to be with you. I knew we couldn't have that with this lingering between us."

"I need to get out of here. I should never have come back. I should have known you would eventually go back to Mark. He's what you want isn't it? He's the one that would be willing to give you the kid I never did? Now you can go and be with him and make your happy little family. Don't let me get in the way."

Arizona grabbed the sofa's armrest and painfully pulled herself up. Pain shot through her body instantly, and she had to hold on with both hands to prevent from falling over.

"Arizona stop, you're going to hurt yourself. Don't do this please."

"No, what I shouldn't have done was let you talk me into coming here. I can't believe I was stupid enough to believe we could work our problems out."

"We can work it out! Please, just give me a chance to explain. Let me explain, and then you can say or do whatever you want to do, ok?"

"I don't think you're in the position to tell me what to do Callie."

"You're right; I'm not. But I don't want you to hurt yourself because of this, and that is exactly what is going to happen if you try to leave. You don't have to leave. I'll leave. I'll give you some time and come back tonight. Please think about this. Please consider just giving me the chance to give you my side of the story."

When Arizona didn't say anything, Callie took it as a good sign.

"Let me help you sit back down."

"I can do it on my own."

Callie decided not to fight her on it. Once she saw Arizona was seated again, she went over to grab her keys and jacket.

"Try to get some rest. I'm sorry Arizona, I really am. I'll be back tonight."

** knock knock**

Sarah Robbins walked over to her suite door and opened it, revealing a broken looking Callie.

"Callie, what are you doing here, what happened?" Sarah asked, stepping aside to let her in.

"I'm sorry to show up unannounced Sarah, I really need to speak with you."

"Have a seat dear. Tell me, what's wrong?"

"I spoke with Arizona shortly after you two left. I wasn't planning on doing this right away, especially the way it happened."

Sarah turned to her husband for a second, communicating without words, before returning to face Callie.

"Ladies, I'm going out for a walk. I'll be back later on." He said, walking out of the room and heading for the door.

"I did something, something horrible, something I regretted instantly, and now Arizona doesn't want anything to do with me. She threatened to leave the apartment and I was left with no choice but to leave myself. I didn't want to leave, I wanted to explain myself, but she shut down and didn't give me a chance." Callie spoke with a sense of desperation in her voice while trying to figure out how best to explain the severity of the situation she currently found herself in.

"What happened?"

"I slept with someone else while she was in Africa."

"Callie…"

"Please Sarah, not you too. I'm completely ashamed of myself. Please let me at least explain."

Sarah nodded and placed her hand on Callie's knee, allowing her to continue.

"You know what happened at the airport; I'm sure Arizona filled you in. I was ready to leave; I had packed up my entire life to follow her to the other side of the world. True, I didn't want to go to Africa, but I didn't want her to leave me. Being 10,000 miles apart for 3 years would've been impossible to handle. Arizona doesn't believe in long distance relationships and that would've broken us. When she left, she took me with her. She broke me apart. Weeks went by and I didn't get as much as a single text from her. I called, e-mailed, texted for weeks and never received a reply. I thought she'd completely forgotten about me. I know she was in contact with one of our co-workers, yet we never discussed her.

"She didn't forget about you Callie. She may not have mentioned or asked about you, but you were on her mind every single day. Arizona and I e-mailed almost daily and there wasn't an e-mail in which you didn't come up. She knew she was there for a good reason, and that the work she was doing was helping so many children… yet she couldn't enjoy it. It didn't bring the sense of fulfillment it should have. She was as heartbroken as you."

"How was I to know that? I know the reason she left, and though I didn't show it, I was proud of her for her accomplishment. I didn't sleep with someone to get back at her for leaving me. The reason I did was because I needed to get her off my mind, even if it was only for an instant. I wanted to not think about her, it just hurt too much. She'd abandoned me and I wanted to forget."

"I'm not judging you Callie; it's not my place nor is it something I want to do."

"The reason I asked you to stay, the reason I'm here now is to ask that you go see her. She wants nothing to do with me right now, and I don't want to upset her further by being there. She won't let me touch her, she won't let me help her, and I'm afraid she'll make her injuries worse if she's left alone much longer by trying to move around."

"Of course I'll go. Let me get my things."

"I've made a copy of my apartment key so you can let yourself in. I'll stay here at the hotel for the time being. I truly don't want to upset her by showing up tonight. I think I'll give her some time to cool off."

"I'll speak to Daniel, and let him know that I'll be staying with my daughter tonight. I'll call you when I think Arizona is sensible enough to listen to reason. This is between you two. It won't be easy Callie; I know my daughter. But I believe that if you truly love one another, which I know you do, you will work this out. Arizona is a proud woman, but she also has a big heart. You'll get through this."

Sarah leaned in and wrapped Callie in a warm hug. "Are you going to be ok alone here honey? Maybe you should call someone."

"I'll be fine Sarah; the one I'm worried about is Arizona. Besides, Addison, a close friend who now lives in L.A., offered to come up here if she was needed. I think I may give her a call later on."

"Call her, it will do you good. Daniel will stay here. If you need anything at all, don't hesitate to contact him. Nothing has changed Callie. You're still a part of our family. We want to help with whatever we can."

"Thank you Sarah, so much, for everything."

Arizona sat on the couch, still trying to wrap her head around what Calliope had told her just a while ago. She slept with someone else. She slept with Mark. While Arizona was off treating and saving the tiny humans, Callie was off having sex with Mark, god knows when or how many times. She didn't want to think about it, the mere thought of Mark's hands on her Calliope made her sick.

The lock on the door turned and she heard someone come inside the apartment.

Arizona sighed and bowed her head. "I'm not ready to see you yet Calliope."

"I'm not Calliope."

Arizona turned so quickly she again felt pain radiate down her left side.

"Mom…" she said, bursting into tears.
