Arizona's POV:

Standing in the elevator beside the most beautiful woman on the planet was not easy for Arizona. It had never been easy to be so close to the one thing you wanted more than anything, but couldn't have. Normally, when she was forced into a confined space with the love of her life, Arizona could keep her cool. She could play the good man in a storm, pretend everything was okay, and get through it without a single sign of the indescribable suffering she was actually experiencing. But today was by no means a normal day.

The blonde had seen her Calliope kissing someone else. Okay, so maybe that someone else had kissed her Calliope. But did it really matter? The point was, Callie had put herself in the position to be kissed. She went out on a date…with another woman. Watching that kiss was gut-wrenching. It hurt Arizona down to the very core she tried so hard to keep locked up tight most of her life. It broke her heart all over again. And if it wasn't for the fact that Arizona knew the woman whose mouth was attacking those perfect, luscious lips, she might have reacted like the scrappy, defensive little girl she used to be and taken back what was rightfully hers. But this woman kissing her Calliope was no stranger. No, she was a person Arizona knew all too well…from the four long and incredibly difficult weeks she had dated her herself.

Arizona had met Heather not long after she had moved to Seattle. She was settling into her new job, her new apartment, her new life. She certainly was not looking for a serious relationship, but Heather couldn't accept that. The older blonde pushed, and manipulated, and forced herself into Arizona's life over the course of a month. And when Arizona finally found the courage to break it off, things got scary- steak knives scary.

Arizona knew she had to tell Callie who Heather was, but what she didn't know was how to go about it. As she stood beside Callie in the elevator, a multitude of emotions surged through Arizona's body. Jealousy. Fear. Concern. Heartache. Regret. Love.

"So…big trauma coming in," Arizona said, her mouth finally able to make words. Not words that meant anything, but words nonetheless.

Callie made small talk about the car accident, although clearly she was just as uncomfortable as Arizona.

"I like your…uh, dress," Arizona muttered, breaking the awkward silence again.

"Thanks," Callie replied, never once letting brown eyes meet blue.

"I don't remember that one," is all Arizona could say, jealousy now at the forefront of those emotions.

"It's new," Callie informed her, further fueling the jealous rage beginning to grow deep inside Arizona's chest.

And then the elevator doors opened, snapping Dr. Robbins back into the reality before her. Car accident. Victims. Patients. Work.

This would get her through it. This would let her forget that Calliope bought a new, sexy black dress for someone else to admire her in. This would let her forget that she would spend another long night alone, nowhere near the gorgeous body underneath that dress.

The next few hours were a whirlwind. Trying to save a young, pregnant woman. Watching her die on the table, never having a chance to meet the unborn baby inside of her. Performing surgery in a trauma room. Delivering a premature, but healthy baby in a futile attempt to make life seem less hopeless for the poor man whose world had just changed in a heartbeat. No matter how sad the situation was, they were successful in saving a life- an innocent, beautiful little life.

Arizona was good at that- saving other peoples lives. It was her life she couldn't seem to save, no matter how hard she tried. She thought going to therapy would help. But clearly that idea had backfired. Maybe she should have talked to a therapist sooner, after the car accident, and the plane crash, and the leg…before the miscarriage, and the cheating, and the irrevocable pain she had caused. Maybe she could have saved herself. Maybe she could have saved them. Maybe then, Callie would still be with her instead of out on a date with a psychotic woman.

Arizona couldn't change the past. She knew that. But she could try and change the future. She could still try and save them. And that had to start with saving Callie from the potentially dangerous situation she was heading into with Heather.

When Arizona saw Callie in the NICU, she was prepared to tell her about steak knives. She knew it would be awkward and uncomfortable, but she had to tell her. After talking about what had happened in the E.R. and going over the baby's status, it was time.

"Callie…about earlier," Arizona called as the brunette began to walk away.

"Yeah?" Callie replied, turning around.

"How long has that been going on exactly?" Arizona inquired.

"It hasn't," Callie said, raising an eyebrow. "I mean that was our first date and it got cut short, so we didn't even make it to dinner."

"Yeah, no. So she just skipped right to dessert."

Arizona heard the words leave her mouth and internally cringed. This is not how she wanted this conversation to go. She didn't want to come across as the jealous ex-wife, although that is exactly what she was. She was the ex-wife. And she was insanely jealous. She may be able to lie to Callie, but she couldn't lie to herself. The thought of that crazy woman putting her lips on Callie's made her blood boil and her heart ache. Those were her lips to kiss and no one else's. Those were her raven locks to grasp between her fingertips. Those were her rich, chocolate eyes to stare into. That was her body to embrace. That was her woman.

"You know what? Let's not do this," Callie said, causing the blonde to snap out of her thoughts.

Arizona fumbled then, unable to just spit out the truth about Heather. Callie began talking, saying something about being kissed and not meaning for Arizona to see it and not needing to apologize, but the words just went in one ear and out the other. Arizona was trying to damn hard to concentrate on what she needed to say to really hear Callie. She was going to do it. She was going to just come out and tell her about steak knives. Arizona opened her mouth again, but before she could say anything…

"I'm moving on now," Callie informed the helpless blonde before her. "And so should you. And it's kind of not your business who I see now…or kiss. Okay?"

Arizona heard those words loud and clear. Her heart dropped. Maybe there wasn't any hope left for them. Maybe Callie meant what she was saying. No. She wasn't really moving on, was she? What if she was? What if this whole time Arizona had convinced herself that they were on the path back to one another, but in reality, Callie was heading in a whole new direction? Had she been fighting for them on her own all along? Was she just wasting her time? How could Callie do this to her?

Suddenly, anger struck the blonde like a bolt of lightening. She was not going to let her heart get broken again. Screw love, and honestly, and maturity. Callie wanted to move on? Fine. Let her move on. Let her date whoever she wanted…even a psychotic, control freak like Heather.

"You're right," Arizona whispered, swallowing the lump in her throat. "Godspeed. Go…kiss everyone."

She walked away then, unable to look at Callie. "Take a deep breath, Robbins," she told herself as she stepped into the elevator. "You need to stay calm and just…j-just forget about her. It's over. She doesn't want you anymore…a-and, and it's over."

Arizona felt the tears beginning to burn the back of her eyes, but she refused to cry. She had done enough crying. No more. No more sadness. No more whining, and complaining, and feeling sorry for herself. "You started this," she whispered, continuing the conversation with herself. "You knew there was a chance you wouldn't end up together after the trial separation. You said it yourself- she's…you're…you're both different now. Those two people who fell in love no longer exist."

The elevator doors opened up, forcing the blonde to stop talking to herself. But even though she couldn't do it aloud, she had to continue working through that last statement. Those two people who fell in love no longer exist. A group of nurses entered the elevator. Arizona forced a smile, practically holding her breath until they got off on the ground floor. She hit number four, the doors closed, and the ride continued. Those two people who fell in love no longer exist.

Suddenly, Arizona didn't have to fight the tears. She didn't have to work so hard at breathing. She didn't have to worry about any of it anymore. The one simple truth she had uttered in anger and sorrow somehow made everything perfectly clear, and she was okay.

The new Arizona didn't want to be jealous and insecure. She didn't want to fight for a person she didn't really know. Instead, she wanted to get to know the new Callie. She wanted to be her friend…her co-parent…her person. She wanted them to have a new relationship…a new life…a new love. Because Arizona Robbins did not want to love anyone else. Old Callie…new Callie- it didn't matter. There was only one human being in the world for her.

So she was going to continue to fight like Hell for them. She was going to learn to love everything about the newer version of her one true soul mate. And if she was really lucky, or even just a little bit right about them, Callie would fall in love with the newer version of her too. They would get to fall in love again.

In that moment, Arizona knew she would find the courage to tell Callie who Heather was. She would find the courage to keep fighting. She would find the courage to believe. Cause believing was not the worst thing that could happen to her. If she took a chance and they didn't end up together again, Arizona would be devastated. But if she never took a chance at all, she'd be destined to lead a life full of doubt and regret. Because what if it could actually happen? What if they could be reborn?

A/N: So, there are way too many things going on (both on the show and in my crazy mind) & it was really tough for me to write this chapter. I am one of those silly, die-hard "love conquers all" romantics and will believe until I see it that they are far from being over. I have no clue how Shonda plans on getting them back to one another, but I see potential clues and signs we may actually get there. When? Where? How? No freakin' clue. But I do believe…
