Disclaimer: I don't own Grey's Anatomy, or the characters, and probably never will.

AN: I have no medical knowledge, just way too much time to search the internet.

Here's the next chapter, fast tracked to you. (Planned to update each of my stories equally, but I was on a roll writing this one)

Thank you so much for all your wonderful reviews, I truly value each and every one of your kind words, so please keep them coming. (And to a certain person - I am not sick, a lot of people only post drama, tragedy, and medical stories. If you don't like what I write then stop reading it!)

Enjoy!

Several minutes later while Callie examines Meredith's severely damaged legs, Addison is setting up to do an ultrasound. The tension in the room is practically palpable, everyone expects the ultrasound to show that at least one of the babies has died, and that is putting them all on edge.

Thankfully Meredith is still under the effects of the sedation, and is unaware of her current situation.

Addison squirts some gel onto Meredith's swollen belly, and then places the ultrasound probe over the gel, after a moment the sound of a baby's heartbeat fills the room. "Okay, there's baby A... strong heartbeat, he's moving around, no signs of trauma."

"What about the second baby? Is it alive?" Callie questions, briefly looking up from applying bandages and splints to Meredith's legs to try and avoid further blood loss.

Addison moves the probe to another point on Meredith's stomach. "Hold on, I'm checking now..." Everyone waits for close to a minute with baited breath, then a slightly different heartbeat echoes through the room. Addison lets out a breath she didn't realise she was holding, and then says "she's still alive... but there's trauma to the upper and lower torso."

"But the medics could only find one heartbeat, how...?" One nurse asks, confused.

"They were only looking for one, and this one's weaker than the other."

"Can you save her?" Callie asks, fighting back tears at the thought of Meredith losing her baby girl.

Addison is quiet for a moment, thinking. "Maybe... I can try to treat baby B's injuries using fetal surgery, I'll perform a c-section, partially deliver baby B, operate on any and all injuries I can find, put her back into the uterus, and close up; try to buy here another month or two to develop, she'll probably end up being born prematurely anyway."

"What about the other baby?"

"It'll hopefully be unaffected, otherwise I might have to deliver him, and he'll go up to the NICU." Addison says, before questioning. "How are you going to proceed Dr Torres? Can you repair the damage?"

Callie looks up at Addison gravely. "I'll try, but... There's so much damage... I might not have a choice."

Within minutes Addison and Callie are following the gurney carrying Meredith towards the ORs.

Over four hours later, almost sunrise. Dr Webber, Bailey, Christina, and Mark are standing back in the ambulance bay. They're waiting for two more ambulances, one holding Izzie, and the other holding Derek, both are said to be in critical condition.

"What do we know?" Dr Webber asks Bailey, who took the dispatch call.

"Stevens was found under debris, she has a possible cord injury, concussion, and multiple lacs. Dr Shepard has sustained burns to over ninety percent of his body, and a severe head injury; he's intubated, deeply comatose." Bailey informs them with sorrow in her voice.

Shocked, Mark brings his hand to his mouth, he knows that there's no way his best friend will survive.

After a moment Christina asks. "Anyone heard anything about how Mere, Alex, and Lexie are doing?"

Dr Webber is the first to absorb the question, and be able to answer. "Addi and Torres have Meredith in surgery; last I heard she and the babies were stable. Karev is out of surgery, and neuro have taken him up to the ICU; he's stable, but there's no sign of brain activity, the nurses are trying to locate his family. And Lexie is up in the burn ward, she should recover quickly, there'll be scars though."

Everyone stands in silence, unsure of what to say.

Several minutes later an ambulance comes to an abrupt halt, causing everyone to jump to action. Mark pulls open the back doors of the ambulance, and upon seeing the burn sheet covering the majority of the person on the gurney he immediately knows it's Derek.

The paramedic leaning over Derek's prone form looks to Mark, and Dr Webber, Bailey, and Christina, who have now gathered outside the doors. "Got a bad one for you. Ninety percent third degree, left pupil's blown, found under 'bout ten feet of debris. Only thing he's good for now's letting your stupid interns practice. Enjoy." If anything she sounds happy about the situation, clearly not knowing who her patient is.

Mark briskly, but gently pulls the gurney out, and with Dr Webber's assistance begins wheeling it towards the entrance doors. He briefly turns back to look at the paramedic. "Thanks. We'll take it from here... and for future reference, don't make stupid, downright insulting remarks unless you know who you're talking about, who you're hurting."

Once they're inside, the paramedic looks to Bailey, and asks. "What was that 'bout? It's true."

Unable to help herself, Bailey raises her hand, and hits the paramedic across the face, hard. "You're patient's our head of neurosurgery, Dr Shepard. He's Dr Sloan's best friend... have been since they were kids." Bailey says angrily, staring down the paramedic until she darts back into the ambulance, and retreats hastily, practically tail between her legs.

Bailey has no time to consider her small victory against the arrogant paramedic, because at that moment another ambulance pulls up.

By the time Bailey and Christina reach the ambulance the paramedics have already unloaded the gurney. Bailey goes straight to the head of the gurney, and looks down to the patient. "Stevens? You with us?"

After a moment, Izzie focuses on Bailey. "Doctor Bailey? ...What? ...Where's George? He was right 'side me."

Bailey looks up at Christina. "Get her inside, page neuro."

Once they've left, Bailey asks the paramedics. "There was one more guy, George O'Malley. Did you find him?"

One paramedic steps forward slightly, and hesitantly says "One we just brought in was found under another person, late twenties white male, is that-"

"Where is he?!" Bailey demands.

"...He was DOA, probably died instantly in the collapse... only had time to shield our patient before..." The paramedic trails off, sparing them the details.
