"Cristina?" Preston addresses her hesitantly.

"Yes?" As she continues, shining the beam of light ahead of them.

"Shouldn't we have been back by now?"

"No."

"Are you lost, Cristina?" he can't help himself and smirks. That would have been quite dangerous if she wasn't walking ahead of him unable to catch him.

"Maybe."

"Don't you think it wise if we come up with a plan, then?"

"Perhaps."

"Cristina, stop for a moment."

She obeyes and shines the flashlight between them so as to illuminate both their faces.

"What? We're not going to get out by just standing here so we might as well just walk." She brushes past him and continues.

"So much for being spontaneous," Preston mutters, then calls after her, "You got us in here you get us out!"

"That's so immature," she calls back.

"What if we don't find a way out? There could be things down here you don't even want to know about."

"You watch too much tv. And what if I do get us out?"

"I'll by you an ice cream."

"More likely I get in on major surgery."

Preston shakes his head desperately yet he smiles. He loves this woman.

An hour later they're still lost in the underground cave. Preston follows his girlfriend and from time to time holds the gauze to his wound with his other hand. Cristina seems determined she's going to find a way out but some negative thoughts are seeping into her mind. Until she hears rustling and stops to listen.

"Why are we stopping?"

"Sh!"

After a moment Cristina continues without giving him any explanation.

"Cristina-" he tries exasperatedly.

"I heard water. Your head okay?"

"Yeah. Yeah, I'm okay."

"Good."

The sound of running water gets nearer, or rather they are approaching, and eventually the light of Cristina's flashlight is reflected by the liquid.

"Aha. That's what I thought. Now all we have to do is follow the stream upwards and there's a good chance we'll be able to get out of here."

"Do you know everything all the sudden?"

"Everything? What do you think? I'm just always super well-prepared for everything, thank you."

After coming to the horrible realisation that they're up in the air and the pilot is having a heart-attack, George and Callie quickly unbuckle their seatbelts and rush to the front of the small plane, Callie grabbing the control column and George tending to Pete.

"George? I- I'm not sure how to fly this thing," Callie admits anxiously.

"Do you think you can cope for 600 seconds?" George asks as he rips Pete's shirt off his chest and applies CPR, the thought that they might crash not even crossing his mind, although this is all Callie can think about.

"I- I'll try to keep it level," she says in a shaky voice, then, "600 seconds?"

"If defribillation is delayed for more than ten minutes, survival rates drop to virtually zero," George answers as he glances at his watch, then continues compressions, then pinches Pete's nose and tilts back his head, breathing two times in his mouth.

"I see," says Callie. "I don't know about you but I don't carry a defibrillator around. I can't land this plane so we can call an ambulance. I'm freaking out, George!"

As George continues CPR, he glances around the plane, searching for the first aid equipment.

"Callie!" he exclaims suddenly.

"What? What George?" she calls back, panicked, making sure they're not crashing.

"Look next to you, there's first aid equipment."

"That's not going to help now, George," Callie assures him.

"See if there's a portable defibrillator. It's a red box and has a heart on it."

Callie starts fumbling frantically and tries to keep focused on keeping the plane level at the same time.

"Er, like th-this?" she inquires as she holds up the box.

"Yes!" bellows George. "Throw it towards me, Callie."

She does and George catches it, then quickly clicks it open and gets the adhesive pads out, a voice giving him instructions.

"Analyzing heart rythm... Stay clear of patient."

A pause.

"Shock advised. Stay clear of patient. Press the flashing orange button now. Deliver shock now. Shock delivered."

"I think we have him back!" George exclaims relieved.

"Thank God," Callie sighs. "You are amazing, you know that?"

George shrugs. "You aren't so bad yourself, flying a plane."

"Yeah it's not that difficult. But ehm, what if we, you know, want to land? How do I do that?"

The gravity of the situation finally sinks in and George frowns with concern. Suddenly saving a life seems benign. If they crash they'll all die anyway.
