A/N this is my first au story. In this story Meredith and Derek knew each other in high school and are the same age, they're both attendings, as are Meredith's friends from the series and the only Seattle Grace characters they've known from their younger days is Mark Sloan.

Prologue

Flashback

"What do you mean you're leaving?" Derek Shepherd sat on the couch in the front room in Meredith's house staring at his girlfriend.

"We're going back to Seattle..."

"Why?" He cut across

"It's my mom Derek. You've met her, you know what she's like. It's not like I can say, hey mom can we stay in New York so that Derek and I can continue this relationship." Meredith was trying not to cry.

"Just promise me one thing. Promise me that you'll still apply to Bowdoin, like we said we would." The pleading was evident to Meredith.

"I promise Derek." The pair stood up and walked to the door where they shared one last kiss on the doorstep before the door closed.

Meredith sat beside her mother in the car as the New York City skyline faded in to the background.

"Are you sure about this Meredith?" Ellis asked her daughter

"Yes mom, I'm sure." Meredith was staring aimlessly out of the window.

"You've got other options Meredith."

"This is what I want mother."

"Ok."

One of Meredith's arms moved to rest on her stomach, which contained the life she and Derek had created together.

End Flashback

Meredith Grey looked around the room of doctors all staring at her 'Why do they always stare? I'm just a surgeon like they are.'

"Doctor Grey is joining us from Mass Gen, where she recently completed her fellowship, we're looking forward to having her work here, she comes highly recommended." Richard Webber said as he finished introducing Meredith to her new colleagues. They shared a smirk knowing who had given Meredith such high praise.

After the meeting had finished Richard introduced Meredith to one of her fellow attendings "Meredith, this is Cristina Yang, one of our cardiothoracic attendings."

"Nice to meet you Dr Yang." Meredith said as she extended her hand to shake the Asian doctors.

"Likewise Dr Grey." Cristina shook Meredith's hand.

"Dr Yang if you wouldn't mind showing Dr Grey to the attendings lounge."

Meredith and Cristina walked down the halls of Seattle Grace "So is it true?" Cristina asked

"Is what true?"Meredith asked right back, although she had a feeling she knew what the question would be.

"That you're surgical royalty, and your mother is Ellis Grey?"

"Yeah, it is."

"Oh that is so cool."

"Yang!" A Booming voice called across the corridor.

"Dr Sloan."

"Are you going to introduce me to your friend?" He asked

"Sure, Meredith this is Dr Mark Sloan, he's slept with most of the nurses here and I'm sure he'll try it with you, but if you just say no, he'll leave you alone eventually."

"Dr...Mark?" Meredith looked at Mark

"Meredith Grey?" Meredith nodded

"I haven't seen you since, wow, you're here." Mark hugged Meredith, when he heard Derek's voice behind him.

"Dr Sloan, hitting on the new staff before she even gets a chance to put her scrubs on?" Derek approached the small group of doctors smiling. "Hi, we didn't get a chance to make it to the meeting earlier, emergency surgery I'm..." He stopped when he saw the face of the new doctor clearly, it was a face he recognised but hadn't seen in nearly 16 years.

"Crap." Meredith grabbed Cristiana and pulled her down the corridor, leaving Derek and Mark staring after them.

"What was that about?" Cristina managed to get out after she and Meredith had stopped running.

"Derek Shepherd and I...we've got a history, it's...complicated."

"Seriously? You and McDreamy? How complicated?" Cristina was firing off the questions quickly.

"It just is, leave it ok."

"All your giving me is you and McDreamy have a McSecret past? I thought we were going to be friends..." Cristina joked.

Luckily for Meredith something had come in to the pit which kept her in the OR away from Derek although she could've sworn that at one point when she looked up from her patient she saw in, in the back of the OR gallery looking at her.

A boy with dirty blond hair walked up to the nurses desk. "I'm looking for my mom, she's a doctor here." The nurse looked at the boy "Dr Meredith Grey." The boy asked

"I'll pager her for you." The nurse said picking up the phone.

"You're looking for Meredith Grey?" Derek asked the boy, looking at him curiously.

"Yeah she's my mom, she forgot to give me a key to the house."

"How old are you?" Derek asked the boy

"15, I'll be 16 in a few weeks. Why all the questions? Are you a freak or something?" Derek was taken aback by the boys answer

"No just an old friend of your moms."

"Mikey?" Meredith asked as she looked at the situation she dreaded, Derek Shepherd was talking to her, their son.

"Meredith?" Derek asked

"Mom you never gave me a key to the house." Mikey said

"Meredith." Derek repeated.

"Derek don't."

"Mom! Key!"

"Cristina!" Meredith saw her new friend walking past. She came over after she heard Meredith yell her name. "Can you take Mikey to the attendings lounge so he can get a key out of my bag and some cab fair." Cristina nodded

"Come on kid." Mikey followed Cristina down the hall glancing back at his mom as she walked down the hall with the other doctor.
