AN: Hi guys, I'm back. I tried to update sooner, but life got in the way! This chapter isn't as long as I wanted it to be, nor did it really turn out the way I wanted it, but I wanted to update the story. So I hope you enjoy. I know I said there would be questions from Meredith and Derek but they'll ask them in the next chapter! I promise!

Oh, also a big thank you to those of you who reviewed! I wanted to thank you all personally, but I didn't have the time. But still thank you so much for reviewing.

Well Enjoy, and you know what to do, R&R!!

Lie about us

'Was that …?' Derek asked still not believing what he had just witnessed.

'Yes.' Meredith answered quickly glancing at Derek.

'Are they …' Derek asked again.

'I have no idea.' Meredith said, than turned to Derek. 'Look it's none of our business okay. Izzie can go out with whoever she likes.'

Derek just looked at Meredith.

'She does owe us an explanation when she gets home though.' Meredith continued before getting into Derek's car.

Izzie was drinking her third beer already, as Mark was sipping from his second scotch, and she was telling Mark about the time that Alex had put her Bethany Whisper ads all over the hospital.

Mark stared at her in shock.

'Seriously? He did that?'

Izzie laughed at his look of disbelief.

Then he said, 'Wait that was you?

Now Izzie rolled her eyes.

'Yes, that was me.' She said signaling to the bartender to bring them another drink.

'Can I see that tattoo?' Mark asked wiggling his eyebrows.

She leaned over the table, pursed her lips pretending to be thinking about it and then said, 'No!'

His face dropped.

'Why not?' he asked, acting like a little kid that didn't get what he wanted.

'Can I see yours?' she asked him with a grin plastered on her face.

He frowned. 'I don't have one.'

'I'm sorry, than you can't see mine!' she answered and then laughed out loud at the look on his face.

He drank his scotch in one gulp and pointed at her.

'You,' he said, 'are an evil woman!'

Izzie just smirked at him and then stood up.

'I need to use the restroom. Now you,' she said pointing at him, 'behave!'

'Don't I always?' he grinned and then winked.

'Sure!' Izzie said sarcastically.

She wasn't even around the corner or a tall brunette walked over to Mark. She sat down in front of him and said, 'I couldn't help but notice you from across the bar.'

Mark just sat there, looking quiet annoyed.

'I'm sorry,' he said, 'but you're sitting on my girlfriends' chair.'

It was out before he knew it, but he didn't care at the moment, he wasn't in the mood to flirt with another woman.

The woman looked around and then said, 'Oh you mean that blonde girl. Isn't she a little young for you?'

'Excuse me?' Mark asked not believing what he heard.

'Well yeah, how old is she? 25? Don't you like someone more mature? Someone with more experience?'

Mark was getting really angry right now. Nobody told him what to do or who to like.

'Look lady, no one insults my girlfriend or …' Mark stopped mid sentence when he felt two arms around his neck and someone whisper in his ear, 'Did you miss me sweetie?'

Mark turned to Izzie and quickly kissed her on the lips.

'Thank you God!' he said and grinned at her.

Izzie smiled at him and then turned to the woman occupying her chair.

'So honey, who is your friend?' she asked, as she stood up straight, making herself really tall; her hands gently massaging Marks shoulders.

Mark shrugged his shoulders and looked at the woman sitting across from him.

'I don't know.' He simply said, then turned to Izzie and winked at her.

Izzie let go of his shoulders and reached her hand out to the woman.

'Hi I'm Izzie.' She said.

The woman looked at her, then at Mark then quickly stood up and moved past her. Izzie couldn't contain her laughter as the woman walked away. Mark smiled at her as she sat back down.

'Thank you!' he said.

'You're welcome.' She replied. 'But I've got to admit, I've never seen you looking so annoyed by a woman's company.'

Mark laughed out loud and then smirked at her.

'Yeah well, I don't like pushy woman and I was really enjoying the company of this beautiful blond.' He said and winked at her.

Izzie rolled her eyes, but still she said, 'Well thank you; I enjoy your company too!'

Izzie looked over at the bar and saw the woman from earlier watching her like a hawk.

'If looks could kill.' She thought. She grinned and decided to annoy the other woman some further.

'What?' Mark asked as he saw her grinning.

She leaned over the table and motioned with her finger for him to do the same.

'What?' he asked her again as they were now face to face.

Izzie didn't say anything; instead she just closed the small space between them and kissed him. The kiss was soft and gentle at first but soon grew more passionate. They pulled apart when air became necessary.

Izzie looked behind Mark to see the woman leaving the bar. Mark followed her gaze. He smiled, but he had a look of disappointment on his face. Izzie saw it before he could hide it and gently stroked his cheek with her hand.

'I'm sorry.' She said a little embarrassed that she got so carried away.

Mark waved her off. 'Don't worry about it. Are you at least satisfied that she ran off?' he asked her while grinning.

'Hell yeah!'

Mark just shook his head.

Mark parked his car and turned of the engine just like the day before, when he had dropped her off. Before Izzie could say anything he got out of the car and was on the other side opening the door for her.

She got out and smiled at him.

'How gentleman of you.' She said as he closed the door and guided her to the front porch of the house.

'It's the least I can do for my girlfriend, right?' he joked as he flashed his McSteamy smirk.

They walked up the few steps and stopped in front of the door. The lights were out so she assumed that everyone was asleep.

She turned to Mark and took his hand in hers.

'Thank you.' She said. 'Thank you for making me forget about my crappy day, and thank you for the drinks and for letting me in on your surgery.'

'My pleasure.' He said and gently squeezed the hand that was holding his.

His other hand went to her face and he gently traced her cheek with his fingers. She closed her eyes and enjoyed the moment. Mark couldn't resist, so he leaned in and gently kissed her soft lips.

Then suddenly the light went on. They quickly pulled apart and turned towards the door. Staring back at them were Derek and Meredith. Derek had a look of complete shock on his face but Meredith was lightly smiling.

Mark set at step back and turned back to Izzie.

'Okay, that's my cue to leave. Goodnight.'

'Yeah, goodnight.' Izzie whispered as turned back towards the door.

She opened it and walked into the house, took off her coat and tried to walk towards the stairs.

'Oh no you don't.' Meredith said, stopping her. 'You've got a lot of explaining to do!'

Izzie sighed. This was going to be a long night!
