Callie Torres opened her apartment door two weeks after her second date with Arizona to see Mark Sloan on the other side holding a six pack in his hand.

"We're still on for the game tonight, right?" Mark asked. "Blondie isn't here to nibble on you or anything? Not that I wouldn't rather watch that than the game."

"Arizona is working and the pizza and wings are on the way," Callie said with a roll of her eyes. She moved back so Mark could walk in. She plucked one of the beer bottles from him when he passed for herself.

Mark set down the container on the coffee table before grabbing a beer for himself. He cracked it open and took a long pull from it before looking at his best friend. "You look different."

"Being happy will do that to a woman," Callie said as she crossed the living room to sit back down on the couch. "Work is going well now that I'm out of residency and can do my own thing; things with Arizona are going well; life in general is good."

"You have been smiling a lot more lately," Mark said as he plopped down next to Callie. The preview for the football game started to play with the sound muted for now.

"I have more to smile about," Callie pointed out.

"I remember that feeling," Mark said as he peeled the label of his beer with the edge of his nail.

"Smiling?" Callie asked with a laugh.

"Being in a new relationship and feeling like everything is going to go right," Mark said. "When Lexie and I first got together, it was incredible."

"Pretty sure the amount of sex the two of you had helped," Callie snorted.

"I always have a lot of sex," Mark chuckled. "Things got harder though with Sloane showing up and everything there. But we're good now. Better than good."

"You're settled down now, matured," Callie patted his shoulder.

"I asked her to move in," Mark admitted before taking a big gulp of his beer.

"Really?" Callie smiled wild at the idea of Mark agreeing to live with anyone, much less the woman he was dating.

"Yeah," Mark said with a boyish smile. "We're moving her this weekend. Who would have thought, right?"

"You're growing up," Callie teased.

"This means you and I can't sleep together anymore," Mark said sadly.

"Mark," Callie snorted as she took his hand for a second. "We haven't slept together since you and Lexie got serious, so I think I will manage to go forward without your admitted talented skills in the bedroom."

Mark laughed and shook his head. "Things really are going well for you and Robbins?"

"They are," Callie said with a wide smile. "She is the first relationship I've been in where we both feel like we're on the same page with everything. Or almost everything."

"She still doesn't know?" Mark asked with a tilt of his head.

"No," Callie admitted.

Mark picked at the beer bottle label again. "When are you going to tell her?"

"I don't know," Callie admitted. "It's got to be soon. I was going to last night when she and I were texting but I didn't want to do it over text."

"You'll find a way to tell her about your past," Mark said as he wrapped his arm around her shoulder.

"I will," Callie said while leaning against him. "But for tonight I just want to watch football and eat junk food and drink beer. Got it?"

Mark laughed as he got up when he heard the knock on the door so he could go pay for the pizza. "You got it, Torres."

"We should stop."

"We should."

"We're not stopping."

"No, we're not."

Arizona wiped her mouth with the back of her hand after she and Callie pulled away from each other. They had been in this on-call room for nearly a half an hour. Both had been slammed at work over the past few weeks but today was their one month anniversary.

Both thought it was a little silly to mark such an early occasion in their relationship and they each had gotten a small token from the other. Arizona had gotten Callie her favorite coffee and a pack of her favorite pens and Callie had gotten Arizona a 3 pack of her favorite donuts from a shop downtown and a stuffed bear for her locker that smelled of lavender.

Arizona cuddled up to Callie's chest. Both had lost their scrub tops in the last half hour, though it hadn't progressed further than making out and feeling each other up. They were half way through their shifts and knew at any moment they could be paged. The warmth from Callie was enough to nearly put Arizona into as close to a sleep as she ever got.

After Arizona cuddled to her, Callie reached down and stroked over the cool skin of Arizona's back as she laid there with a smile on her face. The last month had been among the happiest she had been in her adult life. It was refreshing to be with someone who acted like an adult.

"Tonight do you want to come over to my place?" Callie asked with notable nervousness in her voice. She had always arranged it so they went to Arizona's place when they were together or after dates.

"Are you worried about having to invite me in?" Arizona asked.

'No," Callie said with a shake of her head. "It's not that. I..." Before she could explain she heard her pager go off. "Damn it," she groaned as she grabbed. her scrub top and put it on before climbing over Arizona. "I'll see you later and we can figure out our plans?"

"Alright," Arizona gave a nod. Something was up but right now when Callie had a page to answer wasn't the time to ask what was up. "Go be a badass."

Arizona flopped back on the bed after Callie left and she put her scrub top back on. She only had to wait about ten minutes before she was paged as well. With a sigh, she got up and walked down to the ER where she had been paged.

"What do you have for me?" Arizona asked the nurse when she came down to the ER.

"One of the doctor's kids fell in daycare and hospital protocol is to page peds," the nurse explained. Before she could go into more detail the phone rang.

Arizona took the chart and started to head to exam room three. Before she could fully look at the details on the chart, she was in the doorway of the room. She looked up and saw Callie holding a little girl that looked just like her. Her eyes flashed down to the paperwork and she saw the name at the top.

Sofia Torres.

"They paged peds," Callie whispered as she looked across the exam room to Arizona.

Arizona gave a tight smile as she looked at Callie with the toddler, if Arizona had to guess she would think a bit over a year, in her arms. She looked down at the paperwork and confirmed she was about fourteen months old.

"I can explain," Callie said weakly as Arizona shut the door.

"You don't owe me one, Calliope," Arizona said while she washed her hands. She dried them and put on gloves before walking over to them. "It's only been a month," she whispered as she carefully peeled the temporary bandage off of Sofia's forehead.

"Ouchie," Sofia said as the bandage was removed from her forehead.

"I know, sweetheart," Arizona said in a voice that had been honed at soothing children over years in peds. "We're going to get you feeling better, so you can go home with your mommy and feel better."

Callie held her still as Arizona gave Sofia an exam and then stitched up her forehead. She tried to find the words she wanted to say to tell Arizona about her past and all of it, but she couldn't. Not while Sofia was being cared for by her girlfriend.

After Arizona had gone over everything with Callie as far as take home instructions, she shoved her hands in her pockets.

"I am going to take her home," Callie said as she rocked Sofia to keep her calm. "Will you come over tonight. I'd like to explain?"

"Okay," Arizona agreed with a simple nod. "I have a surgery I need to go prepare for. I'll be over about seven?"

"That works," Callie agreed.

"I'll see you then," Arizona said before walking away.

"Come in," Callie said after opening the door to Arizona at seven that night. "Sofia is already sleeping."

With two words, Callie opened the door to Arizona entering her home. It was a strange thing for Arizona still, that someone had to ask her to come in or she was simply unable to and yet it was a fact of her life.

"How's Sofia doing?" Arizona asked politely.

"Really well. She isn't showing signs of anything, and her stitches look great. Thank you for taking such good care of her," Callie answered with a soft smile.

"Good," Arizona nodded as she pressed her right thumb into the middle of her left palm.

"Wine?" Callie asked. "I picked up a bottle of yours on the way home."

"I would love a glass," Arizona answered with a small smile.

Callie poured them each a glass of wine before bringing Arizona over a glass. For a moment, the pair just stood in the middle of the living room together, neither knowing how to start this.

"Being Sofia's mom and a doctor are the two things I love best in this world. I'm not expecting anything from you, Arizona," Callie said as she looked at Arizona with a nervous look on her face. "I should have told you weeks ago, but dating with a fourteen month old is not always fun. The last month with you has been so refreshing, because I've felt like more than a mom or a doctor again."

"The last month has been pretty wonderful," Arizona agreed. "I really like you, Calliope. And I like kids; it's a side effect of peds. So, being around yours isn't a hardship." She reached a hand up to stroke over Callie's jaw.

"Thank you for not just walking away," Callie said with her shoulders relaxing.

"I don't have to worry about her father getting all territorial if you and I see each other, do I?" Arizona teased. "Because I don't look like I could kick someone's ass, but I promise you I can hold my own," she said with a grin with her dimples popping.

"I don't know who her father is," Callie admitted. "I don't know how I don't know. All the men, and it's not like there were a dozen or anything, I was with around that time were tested. It's like it was magic."

Arizona took another drink of wine, a large gulp this time. "Magic," she whispered to herself. "Or something else?"

"I don't think God had anything to do with it. My mother tried to float that," Callie snorted.

"You didn't happen to have a craving for rare meat or get more sunburns than usual when you were pregnant, did you?" Arizona asked in a slightly strained voice.

"I did, yes," Callie said confused. "It was a pretty easy pregnancy, but yeah I kept getting sunburns, and I ate a lot of red meat."

Arizona pulled away for a moment before running her hand through her hair. "You need to understand when we hooked up I had only been turned about a year. There was still a lot I didn't understand about who I was now. I didn't understand how who I was could lead to consequences." She paced a little back and forth in front of a very confused Callie. "If I had known what happened, I would have made sure to make it right. I would have made sure to be there to ease things. I would be there to make sure that you were taken care of. I hope you understand that when I say what I'm about to say." She stopped pacing to stand in front of Callie.

"Arizona, what are you talking about?" Callie asked. She crossed her arms over her chest as Arizona looked anywhere but in her eyes.

"Vampires have … abilities … to procreate without human means…" Arizona said, hoping Callie would figure it out so she didn't have to say it.

"And?" Callie asked.

"Callie, I think I'm Sofia's other parent," Arizona said as she closed her eyes. "The timing is right and if you were craving extra red meat and getting sunburns it's a huge sign the baby has a vampire parent…"

Callie's eyes went as big as dinner plates as she looked at Arizona. "We're both women. How would that even work?" she asked in shock.

"I'm a vampire, Callie," Arizona reminded her as she lowered her fangs. "Not everything is going to make perfect sense, but as far as I understand it we have to share blood and kiss after. It's not a sure thing but it's like you having unprotected sex with a man."

"Oh my…" Callie said as she stepped back. She started a full on rant in Spanish as she paced the way that Arizona had just finished. All of this time, she wracked her brain trying to figure out who could be the father. Mark and two other doctors at the hospital had DNA tests after Sofia was born and nothing. The whole time, she was looking in the total wrong direction.

"I don't share my blood, so I never think about this," Arizona said when Callie paused. "And until tonight, I hadn't thought about the steps we took. I thought about what we did. God, did I. But not the blood and the kiss and the chance we took when we did."

Callie held her hand up to Arizona as she tried to get her mind wrapped around this. "We need a DNA test. Assuming you're right, and timing wise the three men I ruled out were the only human male options, we really need to have you tested."

Arizona nodded as she thought about the fact she very likely had a child she missed the first year plus of her life. "We can do it at the hospital," she said softly. "I'll go tomorrow and you can take Sofia. It's a day or two, and then we'll know for sure."

Callie took a breath as she tried to wrap her head around all of this. "I'm off Saturday. Maybe we could talk if you have some time?"

"I'm off then too," Arizona said.

"Noon at the diner on 5th?" Callie suggested. "Unless you want to avoid the sun?"

"I'm not worried about that,"Arizona said quickly.

Callie set her wine glass down and then Arizona's. She wrapped her up in her arms and pressed a kiss to her neck. "I know this changes everything, Arizona. I know this changes everything, and we have to figure a lot out a month i,n but I really am glad I finally might know about this and you ... if you want this you'd be really good at it."

"If the test turns out the way we think it will," Arizona whispered as she clung to Callie. "Calliope, I will be there for it all. I need a little time to process this, but of course I will."

Callie rubbed over Arizona's back as she comforted her. She had a lot to process herself. The idea of going from being the only one that had to decide anything for Sofia to maybe dating a co-parent was a hell of a shock.

"In the morning, can you give her a hug? Even if I'm wrong and I'm not, can you just give her a hug for me?" Arizona asked.

"Yeah, Arizona. I can do that," Callie said softly.

Arizona breathed in Callie's scent as they hugged. "Thank you," She whispered before pulling back. "I should go ... I have a lot to think about."

"I understand," Callie promised as she walked her to the door. "Have a good night, Arizona."

"You too, Calliope," Arizona said. She gave a weak smile before walking away.

Callie stood there a moment and looked at the shut door before letting out a breath. A moment later, Sofia was crying in her room. She walked through the door and picked her daughter up and rocked her from her bad dream.

"I've got you, mija," Callie whispered.

Sofia whimpered a little but stopped crying as she clung to Callie. She soon had her eyes closed and her face half pressed against Callie's chest.

As Callie walked over to the rocking chair and sat down, she couldn't help but look over her daughter's face. As she did, she smiled very slightly. She could swear that Sofia had Arizona's nose.

Notes:

I know some people have different thoughts on using Sofia's name when Mark isn't the biological father but I didn't have a better name that came to my mind so I went with it.
