Thanks for the reviews!!! Sorry it's been like over 10weeks I've just been extremely busy with school and this drama things… Also I'm lazy so yuh… Well I think I'll be nice and give you an update now. Enjoy, peoples of earth.

Summary: Hannah doesn't know her birthmother. Izzie doesn't know her daughter… but she knows her husband and her son. Let's just hope they don't clash. McStizzie with Addisex.

Disclaimer: Hate to burst your bubble but I don't own Greys Anatomy. Although I one day hope to lay my claim on Patrick Dempsey.

Chapter 2 – Set 3 months after Hannah's parents deaths

"You'll like Seattle, I can assure you," Addison Montgomery said as she squeezed her nieces shoulder as they flew into Seattle.

Her niece Hannah sighed and turned to face Addison. "I did live here for 8 years; I know what it's like."

Addison nodded. "I know but…"

"I used to live here with my Mom and Dad," Hannah said cutting Addison off. "I get it, but I'm seriously fine with living here."

Addison breathed. "Ok, but tell me if there's something bothering you ok?"

Hannah smiled. "Of course… I'm actually glad to be going back to Seattle; Chicago was always too cold for me." She confessed.

The pilot of the plane announced their decent into Seattle was about to commence.

Addison leaned back into her seat and gripped the arm rest. She hated flying, she hated how her feet would swell, how she had to eat watery soup as 'dinner' and how the flight attendants, a lot of the time, seemed less than pleasant.

"Do you know who my birth parents are?" Hannah asked interrupting Addison's thoughts.

Addison turned to her confused. "What?"

Hannah rolled her eyes. "My birth parent's; do you know who they are?"

Addison sighed. "No and I don't think it's important, Hannah."

Hannah scowled. "Maybe not to you!" she stated angrily. "But it is to me! I need to know who I am."

"You're Hannah Elizabeth Montgomery; you were born on the 11th of March at Seattle Grace Hospital to Greg and Abigail Montgomery!" Addison told her. "They looked after you as a baby, they went to your soccer games, and they packed your lunch for you everyday! They are your parents, Hannah."

Hannah stared at her for a second then shook her head. "I knew you wouldn't understand…"

"Hannah, I…" Addison started but gave up when she saw Hannah put her headphones in. She leaned back into the seat and drew a breath as she looked out the window as they landed.

"Aren't you Mommy's best boy?" Isobel Stevens baby talked to her 3 month old son Jed.

"Hey!" Her husband Mark Sloan placed a hand over his chest and pretended to be offended.

Izzie passed to baby to Mark and grinned. "You're only good for making cute babies." She pressed a soft kiss down on Mark's lips.

Mark looked down at Jed and grinned. "I think Daddy's going to get lucky tonight, buddy."

His white blonde hair was flattened across his head and his deep brown eyes shone as his Daddy spoke to him.

"You're going to get lots of girls too," Mark said in a baby voice.

Izzie shook her head. "He's my boy; no woman will ever lay a hand on my baby boy."

"Hope you don't become a Momma's boy," Mark said to the Jed seriously.

"Addison's back today," Izzie stated changing the topic.

Mark looked up from the baby. "She's coming back with her niece… Her brother died."

"What's the name of her niece?" Izzie asked putting a coffee on the bench for Mark.

Mark screwed up his face thinking. "I think it's Hailey or something… maybe Molly… I think the Dad's name was Geoff or something."

"Ok, poor girl, losing both of her parents all at once…" Izzie said sadly.

Mark stood up and handed Jed to Izzie. "Works calling; I'll see you two tonight." He gave Izzie a kiss and patted Jed's head.

Mark walked out of the kitchen smiling not knowing today would bring a few surprises that may interrupt his now perfect life.

"Hey Mark," Izzie called.

Mark spun around. "Yeah?"

"I might come in to visit today, ok?"

"Ok, sounds good."

"Is it ok if I stop in at work for a few hours?" Addison asked Hannah as they drove close to Seattle Grace Hospital.

Hannah nodded. "I guess so."

Addison shot a sideways glance at her. "Are you sure coz it can wait till tomorrow if you just want to go home now?"

"I said it was fine!" Hannah snapped. "Just give me some money and I'll get something to eat and read a magazine."

Addison nodded. "Ok then, but I promise I won't be over 2 hours." She said pulling into the car park. She took a glance around the car park to see who was around she ducked when she saw Alex Karev. "Shit," she whispered.

"What?" Hannah asked looking confused. Addison didn't answer; her eyes were fixed on Alex. Hannah followed her gaze towards a man walking into the hospital. "Who's that?" She asked quickly.

Alex walked through the doors and Addison snapped out of her trance. "What? Who? Oh that's nobody I just…" She stopped thinking of something to say. "Derek had a jacket just like that and yeah…"

"He's hot," Hannah stated. "You should go out with him."

Addison thought for a second then shook her head and got out of the car.

Hannah followed suit and caught up to Addison as she practically ran into the hospital. "You should," Hannah stated. "I bet I could even get it so he asks you out."

Addison continued to ignore Hannah.

"Fine, it's your loss then…"

Addison stopped and turned around. "Don't say a word to Alex!"

Hannah threw her hands up in defence. "Ok! I promise I won't say a word," She said. "To Alex…" She added quickly.

Addison stared at Hannah for a minute to determine that she was telling the truth. "Good," Addison said finally. "Don't say anything to anyone else either…" Addison stopped and thought. "And especially don't say anything to Mark Sloan."

Hannah looked at her aunty. "Mark Sloan?"

Addison nodded. "He was a friend of Derek's until…" Addison stopped.

Hannah looked at Addison curiously. "Until what?"

"Lets just say that Mark Sloan has a wife who is the biggest gossiper in this hospital," Addison said not answering the 'until what?' question. "So don't…"

"Addison!"

Addison was cut off by a loud voice from behind her. She cringed as she realised who the voice belonged to. She spun around slowly.

"What do you want, Mark?" Addison asked.

Mark threw a hand over his chest and pretended to look offended. "I just wanted to say hello and see how you were doing!"

Addison stared at him.

"I think someone needs a hug!" Mark said quickly wrapping his arms around her before she had time to protest.

"Get off me, Mark," Addison said pushing him away. Addison turned to Hannah. "This is Mark," she told her. "Do you remember him?"

Hannah shook her head. "No, I don't." Hannah extended her hand out to Mark.

Mark shook it but there was something vaguely familiar about Hannah… Her eyes were exactly like Izzies… and like Jed's. "Hey, Holly," He said shaking her hand.

Hannah quickly took her hand back. "Yeah, it's Hannah."

"Hannah?" Mark questioned. That was funny… Izzie's daughter's name was Hannah. "Oh… uhh you don't look like Addison's family that much…"

Addison interjected. "Do you want to get some lunch, Hannah?"

Hannah ignored Addison. "It's because I'm adopted."

Mark took a quick breath. "Oh, right…" She was a spitting image of Izzie. "Well, I um… have to go." Mark said quickly walking off.

"Mark!" Addison called.

Mark spun around. "What, Addison?"

"How are Izzie and Jed?" She asked.

Mark turned around but kept walking backwards. "They're both good! Bye Addison!" Mark turned back around. "Shit," He muttered. "She probably isn't," he said to himself.

"Who isn't what?" Said a voice from behind him.

Mark spun around. "Izzie!"

Yeah, sorry that's such a short chapter!. I'll try to get another chapter up in the next month if I get enough reviews. So review!
