Chapter One- In which there are reactions:

Okay, so George, Alex, Izzie, Meredith and Derek live in Meredith's house. George is thinking about moving in with Callie. Meredith and Derek are together and happy! (Yay!)

He combed his hands through her perfect, fiery red hair.

This isn't what they did. This wasn't what he had meant to do.

Alex Karev wasn't the sort of guy who fell in love; he took a woman out on a date, then they had sex and he never called again. That was how it had worked for years, how he had planned it to work for a very long time.

"Alex…" She moaned softly, digging her fingernails into his bare chest.

This wasn't just sex. He had tried to convince himself it was, but he couldn't. As he held her in his arms, as she whispered his name and smiled at him; looking at him with her stunning blue eyes. He couldn't say she was just a one night stand, because she was so much more.

"Alex. I…" She bit her lip as his fingers found their way around the inside of her thighs.

She had stopped calling him Karev; as soon as his lips had hit hers she had stopped calling him by his last name.

He moved his mouth down her body; making sure to cover every part of her skin with gentle kisses; she lay underneath him, breathing heavily.

Once she hit the bed, she had forgotten all about her problems with Derek and Mark, she didn't mind that the Chief had decided against giving her his job, and she no longer cared that she was having sex with the twelve-year old Alex Karev in Meredith Grey's house full of horny teens.

Alex removed his fingers and as she caught her breath, he smiled his cocky grin that always drove her crazy. "Addie, are you sure you-"

"Oh, for God's sake Karev!" He frowned at the use of his surname. "Two things. One, stop teasing me." She then used all of her strength to flip them over so she was straddling him. "And two. Don't ever call me Addie again."

He chuckled. "Sorry…" He overpowered her and rolled her onto her back again. "Addie."

Bang!

"Ow."

Crash!

"Ow!"

Smash!

"Ow… Ow. Shit."

"Addison what the hell?" Alex rubbed his eyes and turned on the lamp, the sight before him sent him into a small fit of laughter.

"Shut up!" Addison threw one of his shoes at him but he caught it easily. She was lying on the floor; covered in a tangled sheet, objects had been knocked over in her attempt to get out of the door.

"Where do you think you're going?" He grinned.

"To take a shower."

"It's like four in the morning." Alex chuckled, looking at the clock.

"I want to leave before they wake up; they can't see me here, Alex!" She panicked at the thought of Grey, Stevens and O'Malley finding her in their house… In only a sheet.

"Can I come with you?" He asked.

She shook her head. "You'll slow me down."

He laughed but got out of the bed. "If they see you, they see you." Alex picked her off the floor and pulled the sheet with them. "I'm taking a shower with you."

"It's five-thirty!" Addison huffed. "Dammit, Karev, they're all up!"

"So I'm Karev again?" He frowned from he spot on the floor by the locked door.

"No… I'm sorry, habit." She apologised from where she was perched on the side of the bath.

"I say we just go down there. They probably know I had someone here last night anyway." His eyes darkened and she smiled happily.

The smile faded quickly though. "Derek will tease me."

"He's with Mer, he can't judge you." Alex reminded her.

She sighed. "Okay, fine. I'll go down with you, chuck me a shirt." She switched her towel for one of his t-shirts.

"Panties." She frowned, before moving Alex and running quickly into his room in search for underwear.

"Morning Alex." Izzie Stevens smiled.

"Hey." He replied.

"Oh-uh. Dr Montgomery. Uh-Hi." Izzie's eyes widened at the sight of her boss, who was standing timidly behind him.

"Hello Stevens." Addison greeted, trying to look comfy as Alex pulled out a chair for her.

"What-uh- are you doing here?"

"She's with me." Alex said, as if that explained everything.

"Seriously? Like with you?"

"Iz…" Alex warned. "Leave her alone."

"Sorry."

Alex nodded thankfully. "Juice?" He asked Addison and got down two glasses.

There was a sudden chorus of. 'Addison's' and 'Dr Montgomery's' from the doorway, Addison turned to see George, Meredith and Derek all standing there.

"Hi." She half-waved to them all.

"Pancakes?" Alex offered, ignoring his gawking friends and only paying attention to Addison and her breakfast.

She nodded. "Thanks, Alex."

"What are you doing here?" Derek asked, his eyes wider than Izzie's were. "I mean at this time in the morning… Why… Why would you visit at five in the morning. That's a bit early, Addison." He started to stutter. "And why are you wearing Karev's shirt?"

Addison rolled her eyes. "Idiot."

"Derek, you rambling." Meredith nudged her boyfriend lightly.

"She spent the night." Alex told them all.

"Okay." Derek nodded, he pretended not to care and sat at the table.

"Great…" George blushed.

"Yay." Izzie said in her slightly sarcastic Izzie tone.

"That's nice." Meredith agreed and sat next to Derek.

Addison scraped her fork around the pancakes and listened to the group as they tried to whisper.

"Are they together?" Meredith questioned.

"No…. They can't be. McHot and Alex?" George whispered nervously.

"It's sort of cute." Izzie shrugged.

"Cute?" Derek interjected. "The woman I heard upstairs with Karev last night was… Addison?"

"I think it's time for work!" Alex said extremely loudly, they all left the room to hurridly get into the car.

"Clothes." Addison frowned. "I have a lack of clean clothes."

"You can borrow something of Mer's or Izzie's to wear to the hospital."

"Alex." She sighed. "Did you see the looks?"

"What looks?"

"The judgemental looks, the looks that they shared with each other. They hate me."

"They don't hate you." He embraced her.

"I feel like an animal at the zoo. I am a zoo animal!"

"Addison!" He calmed her. "Go take any of their clothes… They do no hate you!"

"Fine." She mumbled and just then she knew, today was going to be hell. "Zoo Animal..."

Should I continue?
