"Look who I found?" Alex says entering Arizona's hospital room.
"Momma why are you in the bed?" Sofia asks as Alex let's her down on the end of the bed.
"Do you remember when I told you about the very special project that Mami and Amelia are working on to help people like me who lost a leg?" Arizona asks and the little girl nods. "Well, it's my turn to get that super special new leg and Mami and Amelia are going to take really good care of me."
"Can I stay here until you come back?" Sofia asks looking around the room.
"Baby, you need to go home with Maggie and Zola tonight. But you can visit me in the morning." Arizona says softly.
"No, Momma. I have to stay here." Then turning around to Alex she asks, "Uncle Alex, will you stay with me until Momma is back?"
"Uh," Alex stammers a minute before he agrees, "Yeah Sof," then to Arizona he adds, "I can drop her by the house after, okay?"
"You're sure? Okay, just let Callie know." Arizona says as Sofia cuddles up to her.
"You're sure about this surgery? It's really sudden." Alex remarks.
"I'm positive about this Alex and it may seem sudden, but to me I'm just glad that it's finally here. I feel like I've been waiting forever to have it." Arizona explains.
"Avery is freaking out, he's trying to get Addison up here. He just gave James temporary privileges, apparently she did a fetal rotation with Addison because she's done everything else." He says sarcastically.
"Alex, she's going to be the new Chief and you'll find that she's an amazing surgeon. Did you know that she has a non-profit and provides disaster aid?" Arizona replies.
"Of course she does. Great, that just means that she'll be gone a lot and then who will be Chief?" He asks.
"Oh, I'm not sure. But I'm positive Jackson is working that out with her." The blonde remarks.
"Hey Cal, Sofia is staying with me until Arizona is out of surgery." Alex informs her sticking his head into the scrub room.
"Wait, why?" Callie asks looking up.
"She begged Arizona to let her stay and see her out of surgery and I think it's a good idea. She's old enough now to know that surgery is a big deal and she's scared. It's not fair to her or Maggie to send her to the house when she's worried about her mom. So I've got this, okay?" He replies turning to leave after impatiently defending Arizona's decision.
"Alex?" Callie calls out to him.
"What?" He says turning back around.
"Thank you." She says seriously, then adds, "Don't let her have any pop or cookies. We'll have pizza later."
"Deal." He says smiling.
Walking back into Arizona's room, Alex is touched to see Sofia reading her mom a story, while the blonde struggles to stay awake.
"Hey," he says softly to Sofia.
"They gave Momma some medicine, so I'm reading her to sleep." Sofia explains.
"I told them to go ahead, that you would be right back." Arizona says struggling to stay awake.
"They should have waited for me to get back. I've got her, so just relax." He says gently to the blonde, taking a moment to brush her hair out of her face.
"Is Momma going to be okay Alex?" Sofia asks.
"Yes, she's going to be better than new. Now give her a kiss. We've got to go up to Peds and check on some kids. Do you have your lab coat with you?" He asks.
Giving her mom a quick kiss, Sofia carefully climbs off the bed and replies, "It's in Mom's office."
"Okay, we'll stop by and get it. Can't do rounds without your lab coat." He reminds her.
"Dr Torres are you done with that?" Amelia asks and Callie sets the small drill down. Then looking over at the anesthesiologist she adds, "Okay, let's bring her out of it and check the placement of the sensors."
Waiting a few moments, Arizona's eyes start to flutter. "Arizona?" Meredith says leaning over her so she can see her.
"Meredith," the blonde says softly.
"Good, you recognize my voice. Now can you open your eyes?" Meredith asks.
Another moment passes and Arizona's eyes flutter open and stay open adjusting to the light in the OR. She moves her eyes carefully focusing on each face and smiles when she see Callie.
"We have facial recognition and control." Meredith replies.
"Arizona, we need you to focus on your leg and raise it up." Amelia instructs her.
Closing her eyes, Arizona imagines that she's raising her missing leg and the screen flashes indicating that she's triggered the correct sensor.
Everyone smiles and Callie says, "Perfect!" The two surgeons alternate instructing the blonde in a series of commands to test each sensor and ensure that they are working properly.
After a few minutes, Arizona seems to nod off. "What just happened?" Callie asks panicking a little.
"Arizona, open your eyes." Meredith instructs her.
No response. The anesthesiologist begins reviewing his settings. "Dr Shepherd?" he asks, waiting for instruction.
"Hold on, just let me..." Amelia says turning back to the sensors and gently inspecting them to determine what's causing this response.
"Wait, that one. Her eyes fluttered," Callie says suddenly, moving towards Amelia.
Stepping in front of her, Meredith says, "Dr Torres give her room to work."
"Dr Grey, move out of my way." Callie says firmly.
"No. Dr Torres stand down or you'll be removed from this OR." Meredith replies just as firmly.
"I'd like to know who thinks they will remove me from this OR. Amelia, talk to me!" Callie replies sharply.
"I've got this Torres, give me another minute." Amelia says adjusting the sensor.
"Dr Torres, she's fine. Look her vitals are low but she's not in any distress." Meredith points out to her.
"Then why isn't she awake?" Callie asks angrily. "Shepherd!" She repeats loudly.
Calmly, Amelia steps back around and softly says Arizona's name.
She opens her eyes again slowly and then noticing the tension in Callie's posture, she asks, "Is something wrong?"
"No, nothing is wrong. You did great." Meredith says quickly to reassure her.
"I had to adjust one of the sensors," Amelia explains lightly.
"So we're done?" Arizona asks.
"Yeah, we're done." Amelia says brightly, then nods to the anesthesiologist to put her back under.
"There's nothing wrong with the sensor. That has happened before Callie, you're over reacting." Amelia counters as they scrub out of surgery.
"She just went unconscious Amelia, is that going to happen again?" Callie asks concerned.
"Look, I get that she's your wife," Amelia says pushing back.
"Ex-wife." Callie interrupts her.
"And your child's mother, so you're not thinking like a doctor, that's why I had Meredith in there. You know that this happens when we first implant the sensors, it's part of the process. This is no different than what has happened with almost every implantation." Amelia reminds her.
"But it was Arizona and she's ..." Callie says trailing off and sinking down to the floor losing it for a moment.
Kneeling down quickly beside her, Amelia pulls her in and says, "She's fine Cal. We did it."
"I know, but I was so scared for a moment that it didn't work and we made it worse." Callie confesses tearfully.
"That didn't happen. So let it go. Okay?" Amelia says stroking her friend's hair softly.
Wiping her eyes, Callie pulls back from the embrace. "God, I'm a mess. I'm sorry about that."
Sitting back on her heels to give the other woman some room, Amelia wipes her own eyes and says, "It's okay. I can't imagine what this is like for you. But let's go join Meredith in post op and see if we can get Sofia in there, you know how worried that little girl is about her Momma."
"Oh god, I forgot that Sofia is waiting with Alex," Callie says scrambling to get up from the floor. Then she takes a moment to splash water in her face. "Do I look okay? I don't want to scare her into thinking something is wrong."
"You look fine." Amelia says, "Let's go."
Turning the corner to the post op, Callie surprised to hear Sofia chattering. As she enters the room, she spots her daughter on Alex's phone sitting in a chair beside Arizona's bed.
"Why is she in here already?" Callie hisses at Alex.
"Meredith came and got her. Arizona was asking for her." He explains.
"Mami, grandma wants to talk to you." Sofia says when she sees Callie.
"Okay," Callie says taking the phone. "Hello Barbara."
As Callie updates Arizona's mom, she watches Sofia carefully watch Amelia examine her mother.
Hanging up the phone, Callie hands it back to Alex. "Why did you call her?" She asks confused.
"She paged me, so I had to call her." He explains, "She freaked out when she got Arizona's out of office message and then couldn't get a hold of you so she paged me. Jeez, I can't believe you didn't tell her parents about this surgery." He adds.
"There wasn't a lot of time and Arizona wanted to wait until morning." Callie explains, then turning to the blonde she says, "Hey."
"Sorry about Mom, you were right. I should have called her." Arizona says smiling at the brunette. "Thanks Alex."
"You're welcome and now I'm going to take this one out for pizza before dropping her off at Meredith's." He says crossing over to put his hand on Sofia's shoulder.
"Mami, Alex and I did rounds today." Sofia says brightly to Callie.
"Did you wear your lab coat?" Callie asks her daughter.
"Of course Mami, you can't do rounds without your lab coat." Sofia replies matter-of-factly.
