Hey Everyone! So here I am with another fic for you all. Hope you will like it. Just to put it out there, I based this story on a movie that I saw a few years ago called Frequency starring Dennis Quaid. The movie didn't do too well in theatres and went straight to DVD pretty quickly but I saw it and thought it was a great one, and then thought the concept would be good to write a similar story for Callie and Arizona, so here it is I hope you enjoy. As usual your comments are welcome and appreciated!

Happy Reading

Summary: This is a story of how an unexplainable phenomenon can reunite two people together.

Chapter 1: A Radio

September 2012

This is the tale of unbelievable circumstances. A tale Of how a natural phenomenon reunited two people who were so in love, that they thought nothing could tear them apart.

Arizona Robbins a detective for the Seattle Police Department was walking up the driveway to her house as the downpour of rain came upon her. She looked in the driveway and noticed there was another car parked. She glanced to the house and found some lights on through the windows. She figured that Sofia, her daughter was home from spending the day with Addison Montgomery and her young daughter Jo.

Addison was Arizona's wife, Callie Torres' best friend. After Callie had died four years ago, Addison really stepped up and helped Arizona to make sure that both her and Sofia were taken care of. Financially, Callie had left them rather wealthy and the Torres' family made sure they were looked after financially as well, but Addison really stepped up to help take care of Sofia when Arizona had to work.

Arizona put her key in the door and once it was unlocked, she stepped inside to the warmth of her house that she shared with her wife. She was greeted by a running five year old girl with dark raven hair and caramel skin crashing into her embrace.

"You're home, Mama!"

"Hey, Sof, did you have a good time with auntie Addison and Jo?" Arizona asked as she held her daughter tight in her arms.

"Yeah, it was fun."

"Where's auntie Addison and Jo, now Sof?" Arizona asked as she let go of her girl and hung her wet coat up on the hook in the hallway.

"They're in Mami's office. We found Mami's radio."

At the words of her little girl, Arizona's expression changed to stern upset one. She marched through the house and straight into Callie's study.

When Callie had died, Arizona had packed up a chunk of Callie's personal belongings and stored them in the basement and closed the door to her office. She never stepped foot in the room since.

"What are you doing?" Arizona asked. Sofia ran past her and joined Jo and Addison in the study.

"Oh, hey Arizona. Hope you don't mind, I was telling the girls about how much Callie loved this radio." Addison said, hoping that Arizona wouldn't get angry with her.

"Umm, no it's fine."

Once Addison and her daughter had left for the night and Sofia was tucked into bed, Arizona made her way downstairs and was about to grab herself a cup of tea when she saw that the door to Callie's study was still open. She made the short journey through the living room and stopped in the doorway to the small office. Arizona just stood in the doorframe and stared into the dark room. Arizona hadn't stepped foot into this room in four years. Everything was as Callie had left it. Every pen, every book, piece of paper and sticky note was in the same place as it was four years prior. Arizona stared down to the desk and saw the radio that Addison had pulled out of the basement. A single tear trickling down her face in the silence of the night. "I miss you so much, Calliope. We both do."

Arizona stepped away, pulling the door shut behind her. Forgetting about that tea that she initially came down for, she headed back up the stairs and to her bedroom. She climbed into the large bed and stared at the empty side in sadness until sleep overcame her.

The next morning, after dropping Sofia off at preschool, Arizona headed down to the station for another unpredictable day at work. Once reaching the second floor of the precinct, she walked down the row of desks saying good morning to every occupant. Finding her desk at the end of the lineup, she plopped into her seat taking a breath before going on about her day.

"Hey, Arizona! Meetings about to start."

Arizona turned to the voice and found her best friend and partner Detective Teddy Altman poking her head out of the conference room.

After they were briefed on the latest case, both Teddy and Arizona headed back to their desks that were situated across from each other.

"So, how's Sofia?" Teddy asked as she glimpsed through the files on her desk.

"She's good. She's doing good." Arizona responded sipping on her cup of coffee.

"And you? How are you? Cuz, I have to say Robbins, you're looking exhausted."

"Had a rough night last night." Arizona responded looking down into her lap to avoid eye contact that would give it away. But Teddy being the best friend that she was, could read Arizona like a book.

"Callie" was all that Teddy said.

"Yeah" Arizona said. "It's been four years and I'm still hurt. I'm still hurt and I'm still so mad. It just isn't fair. It isn't fair that every year for the rest of her life, Sofia won't have her Mami there. Her Mami won't be at her college graduation or her wedding. And there's always going to be one side of my bed that will remain empty."

"I know. I know you're still angry and you're still grieving. That never really goes away. I know it's not fair. None of us do. "

"Well, I don't really want to talk about it anymore. Let's just get going on this case." Arizona said taking the last sip of coffee from her mug and slamming open a file that was waiting for her on her desk.

"So what have we got?" Arizona asked as she approached the uniformed officer surveying the crime scene in front of him.

"thirty year old female. Identified as Sarah Rhonsdon. Body was found by the neighbor. Said they could hear screaming from inside until it just stopped."

Teddy and Arizona approached the body to examine it. They were met with Cristina Yang, the medical examiner who was assessing the body.

"Hey, Yang. How's it look?" Teddy asked, leaning over to get a good look at the body. Arizona stood next to her looking down at the body from where she was standing, not wanting to get any closer.

"Hey, Altman. Until I can get the body to the lab, it's a little difficult to say what happened to her, but I think she's another victim of the Seattle Killer."

"Another one? That's the second one this month." Arizona said.

Cristina stood up and looked back to the detectives as she was ripping her gloves off. "If she is, what do you think this means?"

Teddy and Arizona looked to each other, giving each other that look that meant they were thinking the same thing. Arizona turned her attention back to Cristina.

"It would mean that whoever he or she is, is feeling pretty safe enough to produce more than one victim in a short period of time. And to do it in broad daylight. It's been four years and we still haven't been able to catch this creep."

"Look, we don't know anything for sure. So, Yang just call us when you have something." Teddy said, trying to keep Arizona from losing her cool.

Later on that afternoon, Arizona and Teddy were back sitting behind their desks trying to round up any leads they had that would help them finally catch the killer.

"This is near impossible! This guy is a phantom. Never leaves any DNA, never makes a mistake." Teddy says slamming her papers on her desk in frustration.

"It's been this long, eventually he's going to get cocky about it and he'll slip somewhere."

After a dead end day at work, Arizona went about what had become her regular routine for the last four years. She'd leave the precinct, pick up her daughter and head home for the night.

After dinner, a long cuddle and story session with Sofia, the house was quiet. Sofia was asleep and Arizona was left alone in the silence for the remainder of the night. She made herself a cup of tea to unwind and get ready for bed and stared at the door that had been closed for the last four years until the night before. After Addison had opened it and showed the kids Callie's radio that Arizona's father had given her, Arizona felt this incredible pull. This force within that was egging her on to go inside and sit amongst all that was left of her wife.

She made the short journey through the living room and placed her hand on the handle of the door. Hesitating for a moment, she took in a deep breath and finally turned the knob and walked inside.

Sitting down in Callie's chair, she ran her hand along the smooth surface of the desk. She glanced a little further onto the desk and took in the sight of the radio.

It was one of those transmitter radios that you could communicate on and while Callie was alive, she found it to be the most 'awesomest' thing in the world. She was intrigued and fascinated and sometimes she would come into the office and just listen to the messages that where being sent through the radio. You could pick up a lot of stuff on it. Everything from boats, to planes, and police.

Arizona stared at the radio with a tear forming in her eye. Holding it in, she reached over and flipped the switch on, turning the red light on indicating that it was working.

All she could hear for five minutes was some static and someone trying to say something. Arizona reached for the mouth piece, held down the button and spoke into the microphone. "Hello?"

There was nothing and then all of a sudden Arizona could hear another woman's voice. "Hello, who is this?" the voice asked.

"This is Arizona."

"Wow, don't hear that name often. You are the only other Arizona I know, apart from my wife."

"Your wife's name is Arizona?"

"Yeah. Are you okay? Does the fact that I'm a woman with a wife make you feel uncomfortable?" the voice asked.

"No, not at all. It's just I'm the only Arizona that I know. It's interesting to hear that there's someone else out there. What about you? I don't think I caught your name."

"It's Callie. Callie Torres."

"You're funny. Seriously, what's your name?"

"That is my name. I've been Callie Torres since the day I was born."

"Is this some sort of sick joke?" Arizona demanded. Her anger rising in the pit of her stomach.

"I don't know what you're talking about or why you are getting so upset. You asked me what my name was and I told you."

"Listen to me, I don't know who you are or where you are and quite frankly it doesn't matter but I am telling you this you had better stay away from me. This is Detective Arizona Robbins and I'm warning you now. Stay away from me and stay away from my daughter or I will hunt you down."

"Oh is that so, well whose playing the sick joke now?"

"What the hell are you talking about?"

"You're angry because of my name when you go and steal my wife's name and her occupation. So pardon me for upsetting you but I think I have a pretty damn good reason to call the cops on you for stealing my wife's identity."

"Your wife's name is Arizona Robbins?...Just stay away from me!" Arizona yelled into the microphone. She stormed out of the room and headed up to bed.

She crawled in under the sheets and stared up at the ceiling. What the hell just happened? Who was that and why were there so many coincidences between them

She said her name was Callie Torres and that her wife was Arizona Robbins. Her wife was a detective too. As she continued to lay there deep in thought she went back to the sound of that voice. That woman's voice it sounded like Callie's

Was it possible? But how?
