A/N: This fic is cannon through about season 9. There is no affair, and no separation. The lives of the other characters are mostly cannon as well, except for Cristina stays at Grey Sloan (mostly because I love Cristina and really like having her around). It fits into the same universe as my other Callie/Arizona fics.

Disclaimer: With the exception of one original character, the setting and all characters belong to Shondaland.

Callie carefully balanced the pizza in one hand as she inserted her key into her locked front door with the other, eventually clicking it unlocked, pushing the door open and stepping into her house. It was the first evening in months that neither she nor Arizona was working or on-call. So, after dropping Sofia off at Meredith's for a sleepover with Zola, she stopped to picked up a pizza, intending to surprise her wife with an evening in.

"Arizona!" she called through the house, her heels clicking on their hardwood floor as she closed the door behind her and walked through the dark house in search of her wife. While there were no lights on, she knew Arizona was home because her car was in the driveway. Anyway, it wasn't uncommon for the house to be dark when Arizona was home alone. She always had only the lights on that she needed—it drove her crazy that Callie and Sofia always seemed to leave every light in the house on 24 hours a day.

Callie walked swiftly through the living room, cursing as she tripped over Sofia's toys sprawled out on the floor. She frowned in surprise as she entered the kitchen, dropping her purse haphazardly on the table as she kicked her shoes off carelessly. While it certainly wasn't uncommon for their daughter to leave her things strewn around the house, it was a bit odd for them to still be on the living room floor on days when Arizona wasn't working. While her wife talked a big talk about teaching Sofia discipline and making her clean up her own messes, she usually couldn't help herself from cleaning up on her days off. Looking across the kitchen and down the hallway, Callie spotted their bedroom door sitting ajar with a narrow sliver of light shining into the hallway. Callie headed over in that direction, turning kitchen light on as she left the room. She hated a dark house.

"Hey," Callie said with a smile as she pushed the door open, seeing her wife sitting on the bed with a book, "I brought pizza!" She slipped out of her blazer as she scurried over to hop onto the bed next to Arizona. "I figured since we have the night to ourselves, we might eat pizza and then—" she stopped abruptly as she looked at her wife's puffy red eyes. Setting the pizza on the nightstand, she gently turned Arizona's face to meet hers, noting a couple tear tracks present on her face, "Babe, what's wrong?'"

Arizona forced a smile, planting a kiss on her wife's lips, her unkept blonde locks brushing against Callie's face as she pulled away, "I'm okay. It's just… it's February 17th." Callie's face fell as guilt rose in her chest—how horrible was she to forget? Turning once again to the book her wife had been looking at, she could see an album filled with pictures of a younger Arizona and a young boy with matching blue eyes and dimples. Callie had never met him, but somehow after all these years, she felt like she knew him well.

"It's been fifteen years today," Arizona said, turning her attention back to the photo album. Callie wrapped an arm around her and planted a kiss on her forehead as she looked at the pictures. They were familiar to her now—she had heard the stories year after year on this day, but she would never get tired of it. It was the only way she had of knowing this person that was so important to Arizona.

"This one's of me and Timothy at the base in Guam. I had just turned 10 and he was only 7. God, he drove me crazy that year—there were no other kids his age on the base so he was constantly following me around, begging my friends and me to play power rangers with him," Arizona laughed at the memory, before turning the page to the next picture.

"Oh, this was us at the base in Texas. I was 13 and I had my first crush on this girl in my class named Jennifer with this long red hair," Arizona laughed, "Can you even imagine coming to that realization at thirteen while living in Texas?" Callie shook her head—she genuinely couldn't. "Timothy was the first one I told—he was only 11 at the time. I told him I was gay, and he asked me, 'Does that mean you're gonna marry a chick?'" Arizona grasped Callie's hand as she continued, playing with the ring on her wife's finger, "And I said 'Yes.' And he said, 'I'm gonna dance so hard at your wedding.'" Arizona chuckled sadly, knowing that he would have if he could have been there.

She turned to the next picture, this one of an Arizona who looked to be in her mid twenties clad in light green scrubs, standing next to a blonde man in army fatigues. While in the earlier pictures Arizona was taller than her brother, Timothy had at some point surpassed her in height, and in this photo, he stood a good six inches taller than his older sister.

"He shipped out on his second tour of duty during my last year of residency. I was so overwhelmed with work—I mean, you know how it is: working over 100 hours a week to book as many surgeries as possible, chief resident duties, and somehow trying to find time to study for the boards as well? He was doing his training, but somehow managed to get 48 hour leave to fly over and see me." Arizona's eyes filled with tears once more, "That was the last time I saw him."

Callie pulled her closer, running a hand through her wife's hair, "I'm so sorry, Arizona." The blonde sniffled into the her chest, "It's hard to believe I've lived so long without him." She looked up at Callie and smiled, "And so much of it has been so good. You and Sofia are two of the best things that ever happened to me. I just wish he'd have been here to meet you." Callie nodded in agreement, "Me too."

Arizona sat up, taking a deep breath and wiping the tears from her face, "Did I hear you say you brought pizza?" Callie smiled, grabbing the box from the nightstand and plopping it down on the bed in front of them. Opening it up, Arizona eagerly grabbed a slice, "All I've eaten today has been doughnuts. I think it's about time to eat something other than deep fried sugar." Callie laughed, grabbing a slice for herself. "Yeah, and this is a veggie pizza, so it's healthy," Callie added teasingly. Arizona rolled her eyes, as she bit into her slice. The two of them chewed in silence for a few minutes before Arizona finally spoke up.

"I want to have another kid."

Callie froze, slowly swallowed the pizza in her mouth before turning to her wife, a puzzled look on her face, "What brought this on?"

Arizona shrugged sheepishly, but continued, cautious excitement tinging her voice, "We've talked about it before. We've been talking about it for years, really. And I just think that it's time. If not now, when?" She took Callie's hand, rubbing her knuckles gently as she continued, "Calliope, life is so short and we never know what will happen tomorrow. But I want to raise another child with you. I want Sofia to have a sibling. She should have a sibling."

Callie finally looked up and met Arizona's eyes, a smile spreading slowly across her face, "Okay."

"What?" Arizona responded, her eyes wide, shocked that her request had gotten such a quick response.

"Okay," Callie said again, her smile growing by the second, "Let's have another baby."

In an instantly, Arizona had dropped her pizza back into the box and her lips were locked with her wife's. They were going to have another child. After a moment she pulled away, picking up her slice of pizza once more and taking another bite as she leaned her head against Callie's shoulder, relaxing against her wife as Callie placed a kiss on the top of her head and her arm around her shoulders, before grabbing herself a slice of pizza.
