Chapter one- Tragedy looms

10th November 2009- Thanksgiving

Meredith, Alex, Owen, Arizona, Callie, April and two interns are waiting in the ambulance bay for an incoming trauma. It was a car accident, the second one of the day. Two cars had collided head on after one of them had swerved into the other lane to miss a dog. The holidays were always a very bad time to be out on the road. The death toll was so much higher around thanksgiving time.

"Are you still free for thanksgiving dinner tonight?" Meredith asks.

"Um..." Owen replies unsure of how to answer the question.

"Lexie is cooking," Meredith pipes in. Meredith knew that she couldn't cook, so she had given Lexie the job.

"Sure, we will be there," Owen replies.

"Me too," Alex and April say at the same time.

"You live with us. You don't have to go anywhere," Meredith comments.

"That's why I'll be there," Alex responds.

"Callie, Arizona?" Meredith asks.

"Um, yeah. Sounds great," Arizona replies.

"Why can't people be smart and stay off the roads for the holiday season," Callie replies just as the ambulances pulls up in the bay. Callie, Meredith, Owen and one intern run over to the first ambulance while Alex, Arizona, April and the other intern head to the 2nd ambulance.

"What do we have?" Owen asks, as they over looked a male patient. His face was unrecognizable, bloodied, bashed and bruised. All his limbs looked to be broken. He had a long cylinder pole sticking out of his abdomen.

"John Doe found unconscious at the scene, BP 80/50, tachycardic, we stabilized the protrusion at the scene, we've pumped two bags of fluid," the paramedic says.

"Thank you, we'll take it from here," Owen replies as they rush to get him inside.

"What have we got?" Arizona asks as they over looked a female patient. Her face looked much the same as the male patients. It looked bloodied, battered and bruised. She looked to be 22 weeks pregnant and had a fetal monitor strapped onto her. Her legs looked to of been crushed.

"Pregnant Jane doe. She's been tachycardic, BP 60/90. Baby's heart beat is strong," the paramedic says as they rush her through to a trauma room in the ER.

When they reach the trauma room Arizona preforms an ultrasound to check on the baby. "Baby is doing well. Heartbeat is very strong, but I'm going to page OB just in case. How is mum doing?" She asks Meredith.

"She is showing typical signs of a Basilar skull fracture. Let's take her up to CT and page Nuro," Meredith says.

"Let's go!" Robbins says. They rushed her up to CT where she began to crash.

Three hours later

Defeated, all the Attending's and residents who had worked on John and Jane Doe stood up outside the NICU as they watched Dr Robbins care for the 8.6 ounce baby girl that was delivered from Jane Doe at just 22 weeks gestational age. The tiny baby was hooked onto a high-frequency oscillatory ventilation machine to help sustain her life. It was going to be one hell of a fight to keep her alive.

The team knew they had worked like crazy and had done everything by the book to try and save the future parents. They couldn't work miracles and both had bleed out on the table.

"Has anyone been contacted? Does anybody know that this baby doesn't have any parents?" Meredith asks as she along with, Alex, April, Callie, Owen and Derek were standing outside of the NICU.

"Police have been informed about their deaths and are going through personal effects found at the scene in order to find the next of kin or an emergency contact. In the mean time we are running the baby girls blood in order to find out her blood type and give her a transfusion," Owen says.

"Poor baby, she doesn't know what a fight she has to stay alive. She needs support from her parents and she'll never get that now," April says.

"I know this was a hard loss, but we saved the baby and we are doing our best to make sure she lives through this. This isn't going to be easy for her. But the first people she met in this world was you lot, you may not be related to her by blood, but you're her family now," Owen says.

"One of us is. One of us is related to her by blood," Cristina says as she walks up with the blood results. She hands the paper to Owen.

"What are you talking about yang?" Callie asks.

"Lexie. The blood test results show that the baby has O-Negative blood and that her biological mother is Lexie Grey," Cristina says.

"What! How? That was not Lexie on the table," Meredith says raising her voice.

"I.. I... I don't know!" Cristina replies back.

"I do," Lexie replies as she walks up to the group holding the hand of her 7 year old daughter, Layla-Rose Caroline Nicolas-Grey. She was born on Lexie's 17th birthday on the 7th of March 2002. She would be 8 in about four months.

"I went to med school with Jane Williamson. She was in her final year when I'd just begun. We became very very close friends, she was my best friend. After two years of trying to get pregnant Sam and Jane went to a specialist and found out that she was infertile. They desperately wanted to have a baby so I offered to donate my eggs so she could have a baby through IVF. So they harvested some of my eggs and mixed them with Sam's sperm sample and we had 12 embryos. They put the one embryo into Jane and it stuck to her uterus on this first try. That's how I'm the biological mother of the baby," Lexie explains.

"I'm so sorry Lex, but Jane and Sam didn't make it out of surgery," Meredith says.

"I know," Lexie sobs as she collapses onto Meredith's shoulder. As the emergency contact, Lexie had received a phone call from the police explaining the situation, she had gone down to the police station with Layla and they gave her all the details about what happened and sent her here. She cried on Meredith's shoulder for half an hour before calming down.

"Their baby, what happens to their baby?" Lexie asks as she looks at the micro premature infant through the window.

"I don't know Lex, I don't know," Meredith replies as she side hugs Lexie. Layla looks around the hospital, unsure as to what was happening.
