Arizona in 8x24.

"ARIZONA!" Cristina snapped suddenly. "Are you sleeping?"

Arizona looked up. "No. Not sleeping." She had been, though. Sleep was the only thing that distracted her from her agonizing thigh, the bitter cold, and Mark, lying his head on her other thigh— nearly dead.

"Good," Cristina clipped. "Don't."

Arizona nodded slightly, until a hacking cough overtook her body and she was spitting up blood.

Cristina's eyes went wide. "Is that...?"

Arizona nodded. "Must be. Pulmonary embolism. And I'm pretty sure I'm in hypovolemic shock."

Cristina wanted to scream. This couldn't be happening. They were all dying. "What else...?"

"Osteomyelitis. It's been two days, right? The bone has to be infected by now."

"Which means..." Cristina couldn't even say it.

"I'll be septic soon. And then my organs will fail. And then I'll die." Arizona tried to smile. She was completely hopeless.

After a minute, though, Cristina sprung into action. "No. You are NOT going to die. Okay? No one else is going to die." She grabbed one of the water bottles from the ground beside her and eased closer to Arizona, sitting on the side of her mangled leg. "I'm going to clean out your leg, and Callie and Owen are going to find us. They're looking, and they're going to find us."

"Maybe." Arizona knew better than to believe Cristina's optimistic words. There were miles of forest around them on all sides. There was a very real chance that, by the time they were found (if they were found), they would be long dead.

A little too loudly, Cristina yelled, "Mark! Can you hear me?"

The nearly comatose man grunted slightly.

"Hold Arizona's hand," Cristina instructed. She looked at the blonde attending apologetically. "This is going to hurt. More than you can ever imagine. But, it could help. It could save your leg. Are you ready?"

Arizona grabbed Mark's hand and clutched it tightly. "Ready," she croaked. She squeezed her eyes shut.

Cristina shoved a pen through the bottle cap to create a small hole, then regretfully, began squirting the water onto and around Arizona's exposed bone and brutal leg injury.

Arizona let out a scream so loud and excruciating that it was surely breaking glass windows all the way in Seattle.

"I'm sorry, I'm sorry, I'm sorry," Cristina murmured as she continued to clean the wound.

A second later, the pain became too much to bear, and Arizona lost consciousness.

"Arizona? Can you hear me?"

Arizona looked around, trying to understand her surroundings. "What happened?"

"I was debriding your leg and you passed out."

Arizona looked down. Oh, yeah. Her leg.

Cristina turned and looked toward where Meredith and Derek must have been. Arizona couldn't see much from where she was sitting, and she couldn't move to get a peek. Cristina said, "I need to go check on Derek. Are you going to be okay for a few minutes? Don't you dare crap out and die on me." She kicked Mark's shoe. "You either."

Arizona swallowed the blood and phlegm clot that had worked its way up her throat. "We'll be okay."

Cristina nodded. "Good. Drink fluids. Don't fall asleep. And, Arizona," she paused, "Think about Callie. We'll get you home to her. And Sofia. We will be fine. We have to be."

"Okay." Arizona didn't have the energy to say anything more.

After Cristina was gone and the leg pain began to consume her, Arizona decided to follow the younger doctor's advice and think of Callie. Maybe it would help her survive.

Arizona woke up to the feeling of soft lips grazing her cheek. She stirred, and Callie whispered, "Good morning, gorgeous."

Arizona opened her eyes only to see the most breathtaking smile imaginable. "Good morning," she whispered back. Callie was perched on the edge of the bed, looking down lovingly at Arizona, and the blonde pulled her down toward her. She needed to feel those luscious lips over her own.

Callie grinned into the kiss, her smile so wide that the action became impossible. She pulled away. "Guess what?"

"What?" Arizona asked flirtatiously.

"I made my wife breakfast."

Arizona felt her heart soar at the statement. She was Callie's wife. If she only heard Callie murmur those words for the rest of her life, she would die happy. Arizona dimpled and sat up in bed. "Mm. You're a good wife."

Callie shrugged good-naturedly. "I figured it was the least I could do to thank you for last night." She laughed, remembering their blissful, sleepless wedding night.

Arizona laughed pridefully. "We have a lifetime of nights left together. You going to make me breakfast every morning?

Callie raised an eyebrow. "If they're anything like last night, then you bet."

Arizona smiled at the memory. She needed to get through this. She needed to get home to the woman she loved.

And home to her daughter. God, Sofia...

"She's going to walk tonight! I can feel it." Mark was watching Sofia from his place in the kitchen. "Look at her! She's standing. She's ready."

Callie and Arizona were seated on the rug, watching Sofia as she stood shakily, her little baby hands gripping the coffee table to stay upright.

"She's only ten months! Isn't it too soon?" Callie was doubtful that it'd happen yet.

"Babies learn to walk between nine and fifteen months," Arizona offered her professional wisdom. "And Sofia is precocious. Aren't you baby?" she cooed.

"It's gonna happen, Cal," Mark insisted.

"Uh huh," Callie answered dubiously.

"Mark's right. Watch." Arizona stood up and moved to the couch, which was a few feet away from Sofia. "I'll prove it to you." She turned her attention to Sofia. "Hey, Sof, wanna try walking today?"

The toddler looked up.

"Yeah! Come on, come walk to Mama."

Mark rounded the corner of his kitchen and sat down on the opposite couch. "No way, Robbins. She's coming to me first." He clapped his hands together to get little Sofia's attention.

"Mark..." Callie began.

"I've got this, Cal," Arizona winked. "Sofia! Come to Mama!"

The toddler took one hand off the coffee table, wanting to fulfill her mom's request.

"Yes! You've got this, big girl! You can do it. Just walk a few steps."

Sofia grinned and let go of the table. She wobbled for a second before falling backwards.

Callie quickly picked her off the floor. "Wow, that was brave!" she praised. "Try again, baby. Go to Mama!" she pointed at Arizona, who was positively twinkling at their daughter.

"Come on, Sof! Try again!"

This time, Sofia was a little more sure-footed, and she managed to stand on her own for several seconds. Finally, she teetered forward, quickly placing one foot in front of the other as she tottered toward Arizona.

"You're doing it!" Arizona grinned.

"She's doing it!" Mark and Callie reiterated, ensconced in the incredible sight before them.

"Keep going! You're almost here!" Arizona called. Sofia toddled the last few inches until, giggling, she fell into Arizona's arms. "Good girl!" Arizona hugged her.

"Calliope..." she leveled a stare at her wife. "Look who was right again." She winked at Callie, and the brown-eyed woman winked back, beaming.

"Mark?" Arizona whispered unsteadily, praying that her child's father's heart hadn't stopped while she'd been daydreaming. "Mark?"

"I should've said it earlier," Mark croaked. "That I loved her. I should've said it earlier."

"She knew. I think she knew."

"She didn't know," Mark insisted. "She didn't know."

"Mark?" Arizona tried again. "Mark, hold on. Okay? I need you to hold on."

"You'll be okay. You don't need me. You take care of our girls."

"No. Shut up. Shut up. Do you hear me? Shut up."

"Lexie's waiting for me. I'll be okay."

"NO! Mark Sloan, no. Okay? No. Sofia's waiting for you. And Callie's waiting for you. And I am waiting for you. We're going to go home together, okay?"

"Okay," Mark conceded. "Okay."

"Okay," Arizona breathed. "Okay."
