This update is up way later than I wanted it to be. Sorry! I've been busy with school and just found myself too tired when I did have the time. But it's up now and I'm hoping that the next one can be up by Tuesday at the latest. I can't promise that, but I'll really, really try.

"It's crazy," Mark said as he helped Arizona put the finishing touches on Sofia's room at her place.

It had been three months since Callie's death, but the pain was still just as fresh. It would hit them at times like these – the day before their daughter would come home – that they really hadn't talked to Callie in three months. It still seemed so unreal, almost as if she could just walk through the door and they could resume their "normal" lives at any moment.

"Yep," Arizona sighed.

They couldn't bring Callie home and they didn't know if they would ever fully accept that. However, Sofia was doing significantly better than she had been. She was just about two ounces shy of six pounds and she would only need to be on oxygen overnight for awhile when she got home. None of her other issues were still causing major problems. Her parents knew that Sofia wasn't like the typical three-month-old, and that she may have delays, but so far, so good. She was certainly a miracle baby.

"She's gonna love this," he said, looking around the room.

It was yellow and white with lots of feminine touches all around. Family pictures – including the last ones of her madre – were already proudly displayed on her bright walls.

When he was trying to think of ideas for her room at his place, he couldn't come up with a single one. Finally, he came up with the perfect theme. The walls were a dusty rose colour with white tree decals up on them along with other nature-like elements. It was just girly enough for his little princess and it captured her first nickname – "The Mighty Oak" – so sweetly. It might have been cheesy, but he thought she'd enjoy it. She had certainly proved herself to be small, but mighty.

"We should have some kind of party."

"Huh?"

It was as if the word "party" was entirely foreign to him. Parties involved fun and there wasn't much fun being had these days. Between NICU visits, work, preparing to bring the baby home, and trying to do just about anything not to think about Callie all day long – which then lead to guilt over not wanting to think about her – they were just too worn out for any fun lately.

"So much has been sad," she explained. "Her whole life has been so sad. We need to start celebrating her."

"I don't think throwing a big party for a preemie who's fresh out of the hospital is the best call."

"Well, it's not like we'll have strangers around. All of these people have already been around her."

"True. Fine."

"Sorry," she said. "It's just...I'm sick of feeling like this."

"You don't have to tell me that," he said. "I get it. Yeah."

"I don't want her to always have to live with Callie's death hanging over her head."

"Yeah."

"I can't believe I didn't want kids," she said as she hung the lowercase "I" in her daughter's name on the wall. "And then I warmed up to the idea because Callie'd be here and she'd be such an amazing mom. And she's not even here."

"I say it way too much, but it's just so unfair," Mark nodded.

"I mean, I didn't want kids because things happen to them. Then I end up the single mommy of a micro-preemie and I wouldn't trade her for the world."

He smiled. "Nope."

"We can really do this, right?" she asked. "Raise her to be as good of a person as Callie'd would've?"

"Yes," he said. "That or she'll be really, really messed up."

She laughed.

"Sofia," Arizona smiled as they walked over to their daughter the next morning.

She had been in the regular nursery since yesterday, since she was no longer sick enough to need the NICU. She had passed her carseat test last night they'd been told, so she was all set to be discharged.

"She had a bit of a fussy night," the nurse explained. "But that's just the reflux. She's good to go."

"Yeah," Arizona nodded. "Her dad's signing the discharge papers right now."

"Good," she replied. "It's about time she get to go home."

"It is," she agreed as she picked the little girl up. "Huh, Baby Girl?" Sofia let out a little cry as Arizona's lips kissed the top of her head. "Oh, shh," she replied. "I'm mommy. Mommy kisses are a good thing, Silly!"

"You're all set, Sofia," Mark announced as he walked in. "You get to go home."

Arizona "clapped" one of Sofia's little fists against the other. "Yay!" she cheered quietly. "You ready?"

"All we've gotta do is put your little outfit on," Mark said, getting it out of his daughter's diaper bag. He handed it to Arizona. The tiny little girl would be wearing a bright orange little dress home. She was still in preemie sizes, but soon all of her "big girl" clothing would probably fit.

"You're gonna look gorgeous," Arizona told the baby as she dressed her. "Not that that's hard for such a pretty baby, but you will."

Mark took the matching flower headband out of the bag as well. "Is this necessary?"

"Yes," Mommy nodded as she took it from him. "It is. It's pretty. Right, Sofia?"

"Fine."

"Say 'Daddy, just be happy I'm gettin' out of this place!'"

"Oh, we're happy," Mark said. "That's for sure, Sof."

"Yep!" Arizona smiled. "Mommy and Daddy like it here. This is our work. It was Madre's work, too. But we thought it was pretty yucky that you had to be in here. This is no place for such a new little girl, is it?"

Derek walked in. He was really there to check on the suspicious neurological symptoms one of the babies seemed to exhibit, but he'd be lying if he said he hadn't timed the visit with Sofia's departure.

"It's Uncle Derek, Baby," Mark told her.

Derek came and picked the little one up as soon as Mommy had finished dressing her.

"You're goin' home, aren't you?" he smiled. "No more hospital for you, right?"

"Right," Mark nodded. "Now give me my kid," he smiled, reaching out his arms. "We kinda wanna get her home as soon as we can. We've had enough of her not being home."

Derek kissed her and handed her to her daddy. "Here."

"Say 'bye, Uncle Derek!'" Mark smiled.

"Oh, we're having a party," Arizona told Derek.

"A party?" he questioned.

"A bit of a 'welcome home' thing," Mark explained. "Friday."

"Okay," he smiled.

"Because we need a little celebration," Arizona added. "We've decided. Haven't we, Sofia?"

"Good idea," Derek nodded. "Auntie Meredith and I'll have to do our best to make it."

Mark kissed his daughter. He had to admit that the ridiculous flower headband wasn't all that bad. It kind of suited the baby, actually.

"Time to go home," Arizona smiled.

"Finally!" Mark agreed. "Let's go, Pretty Girl."

"Welcome home, Sof," Mark smiled as he walked through his doorway with Sofia in his arms for the first time.

This was a moment he'd been looking forward to ever since Callie told him she was pregnant. It was supposed to be one of the most joyous times of their life, and it was, but it was also sad now. He hadn't imagined it going anything like this. He hadn't thought that Sofia would be a preemie, or that Callie would miss out on her whole life. The lack of her presence was hard to take. He wanted this to be a celebratory moment, but that wasn't completely possible yet. He just hoped it would be one day.

"This is Daddy's place," Arizona told her, trying to force the happiness to come. She too was thrilled to have Sofia home, but this wasn't nearly as easy as they had wanted it to be.

"Mommy lives across the hall," Mark added. "Sometimes you'll go there, and sometimes you'll be here."

"You get two pretty rooms just for you."

Mark kissed his little girl's head. "Uh huh," he nodded as he walked back to the nursery. "Look," he said, holding Sofia up a little so she could see the room. Clearly, she wasn't looking, but that wasn't really the point.

"It's nicer here than it is in the NICU, right?" Arizona asked.

Sofia started fussing. She wasn't too unhappy, but her little cries let them know that she needed something from them. "What's the problem?" Daddy wondered.

"It's just about bottle time," Arizona realized.

"Should we see about getting you some formula?" he asked. "You love that stuff, don't you?"

Friday rolled around and Arizona yawned as she fed Sofia. Her welcome home party was starting soon, but the hosts were pretty worn out. They hadn't really had a good night's sleep since the accident, and the baby didn't really help matters.

"How come nobody tells you bringing a premature baby home is hell?"

"Because they'd just sound like a terrible person," Mark said. "Plus, she's worth it."

"Well, yeah."

"And this is just a phase. She will sleep through the night one day."

Arizona looked down into Sofia's eyes. "One day soon, please," she requested.

"Tell me about it."

"She'd love this," Arizona said, obviously referring to Callie. "And we're complaining."

"We're not complaining about the baby," he justified. "She's awesome. It's just the lack of sleep."

"True," she yawned.

"And she'd be complaining, too," he said. "You and I both know it."

She laughed. "Okay, true," she agreed. "But still. I mean, we made it through residency and a six pound baby has us losing our minds?"

There was a knock on the door and Mark went and answered it. "Hello," he said, surprised to see Cristina on the other side of the door. "You're the first person to show up? You know this is a party for a baby, right?"

"I'm her Godmother," Cristina said, walking in. "Owen said I had to come."

"Well, thanks."

"Where is Owen?" Arizona asked.

"In surgery," she said. "Where I should be."

"Auntie Cristina does love you," Mommy told her little girl just as she finished her bottle. "You all finished? Good."

"But I should be in surgery," Cristina told Sofia. "It's where I belong. Plus, I'm not your aunt. And definitely not your 'auntie.'"

Arizona handed the empty bottle to Mark and went to hand the baby over to Cristina.

"Oh, okay," Cristina said as she took her. "Apparently I'm holding you."

"Say 'I'm not so bad!'" Arizona said. "'And you know you love me.'"

"At least you're not screaming," Cristina said. "I do like that about you."

"Callie wanted you to be her Godmother why?" Mark questioned.

"Because I may not be good at bottles and diapers, but I will turn her into an amazing surgeon one day."

"Which is Auntie Cristina's way of saying she loves you," Arizona smiled.
