So if you haven't heard the song "Hold My Beer" go listen to it now. It's hilarious. I actually switched this shapter around so that it would fit the song better. I mean it can only fit so well because neither Addison nor Meredith are his girlfriend. But whatever.

Just read it.

Some nights Joe feels as if there are invisible lines dividing his bar. Everyone in separate corners, but acutely aware of the other occupants.

Tonight Derek Shepherd had arrived first, right at 8 as he had most evenings lately. He sat at the end of the bar and ordered, but didn't drink. Just stared. He was in a mood. If there was one thing that Joe had noticed about Derek, it was that he was moody.

Next through the door was Meredith Grey and Izzie Steevens. This had surprised him, they did not frequent his bar as much as they used too. Although maybe they should, Meredith did not look herself. In fact, she seemed downright depressed.

Neither girl acknowledged Derek, and he pretended not to see them. Although Joe noticed that all three were stealing glances at eat other. Izzie in particular.

Then came Addison. She was the walking polar opposite of Meredith Grey. She caught Derek eye and smiled, giving him a small wave. She seemed to shrug it off easily when he turned away from her. She just raised her eyebrow and ordered a drink, carrying it with her to the back. She waved to Meredith and Izzie as she settled a few tables away. Only Izzie waved back.

Joe's favorite entrance by far was that of Mark Sloan.

Mark nodded at Derek.

Derek glared.

He leaned against the bar and winked at Addison.

Addison glared.

He grinned at Meredith.

Meredith glared.

Even Izzie glared when Mark started to walk towards them.

As far as Joe was concerned, it was perfect. Perfectly tense. But perfect.

"Meredith," Izzie hissed as Meredith drained another shot of tequila, "DOn't you think that you should slow down."

Meredith shook her head but didn't look up from the table, "We came here for drinks. I'm drinking."

"But..."

Meredith tilted her head to the side in order to look at Izzie without lifting her head, "Have another shot."

XXXX

Mark tipped his beer back and drained half the bottle. He set it back down on the bar with a clank, but never took his eyes off Derek at the opposite end of the bar. The man was a mess. He kept his head down except to steal occasional glances at Meredith who was ignoring his existence and Addison who had her feet up on a chair, sipping a martini and reading vogue, oblivious to everyone.

Mark heard the bell chime behind him as someone entered the bar. He watched Derek look up, and saw his body instantly tense up.

Interesting.

XXXX

Meredith stared down the bottom of her glass. She just needed a month where everything went semi-right. Just 4 weeks in a row where none of her family members were admitted to the hospital, 30 days where she didn't have inappropriate sex, or have to break up with her boyfriend or forget to take the garbage out.

That's it.

That's all.

"Mer?"

Meredith glanced up and instantly let out a relieved sigh, She slowly stood from her chair and wrapped her arms around Finn's waist, "You came back."

"A little birdy told me that you really needed a hug," he said, kissing her forehead and smiling at Izzie as she slipped away and went to talk to Addison.

"I did," Meredith sighed, refusing to let go, "I really did."

XXXX

Mark drained his beer and watched his former best friend glare at Meredith and a man Mark assumed to be a boyfriend. He almost felt bad for Derek. He knew from experience that it almost physically hurt to have someone you care about have an intimate moment with someone else, right in front of your eyes.

On the other hand, Derek had been less then desirable as a best friend during the past 2 years. And that was aside from everything that had happened with Addison. At this point he didn't feel he owe much loyalty to the man.

But still, it did suck. He felt bad for him.

Mark ordered another beer for himself, and one for Derek.

Derek looked up in surprise. Mark nodded and tipped his beer towards him in a silent cheers.

Then he crossed the bar to where Addison and Izzie sat.

He didn't really feel that bad.

Mark leaned close to Addison, ignoring her attempts to move away and her hostile words. He murmured something nonsensical in her ear, then grinned triumphantly as he saw Derek stalk from the bar.

He'd won that round.

It was still early morning as Addison walked back through her front door and set Truman on the floor, smiling as he ran across the hard wood and disappeared into the living room. She followed close behind him rummaging through her purse as she walked.

Suddenly she stopped dead in her tracks.

She stared into her living room then turned and walked back out of the house. She marched down her front walk until she got to a particular paving stone. She bent down, pried it up and stared.

She spare key was still there. It hadn't even been moved.

She turned and walked purposely back into the house.

"Get out."

"This bird is not very friendly.," Mark replied ignoring her comment.

"Get out of my house," Addison repeated, trying not to explode.

"She liked me fine when I bought her," Mark continued, not moving from where he was sprawled comfortably on her couch.

Addison crossed the room to where her lovebird was sitting placidly in her open cage.

"Good girl Astrid," she whispered affectionately to the animal which, until this very moment she only held a passing interest in. She turned back to Mark, "Out."

"You used to be much more hospitable."

"Well I don't make it a habit to entertain people that break and enter."

"I took the room with the walk in closet."

Addison stared, "Excuse me?"

"I thought moving right into your room was presumptuous. But I'm not really settled if you want me to move," he grinned at her.

"I want you to move out the front door."

"I cross the country every weekend to see you and you won't even let me stay in one of your guest rooms?"

"Out," She pointed to the door.

Mark stretched and reached for the remote, "Do you get ESPN?"

Addison continued to stare and then glanced at her watch. She was late. "I will be back in 4 hours. You had better be gone." With one last glare she pet an already sleeping Truman and a preening Astrid good bye.

"I mean it Mark," she called back as she closed the door.

He had caught back up with her by the time she arrived at the hospital. She had noticed him a few people behind her when she stopped for coffee, but thought she had lost him after that.

"What do you want?" she demanded, spinning on her heel to face him.

"You," he replied simply.

"Well you are going about it completely wrong."

Mark nodded, "Okay."

Addison looked at him suspiciously.

"I'll try something else."

"Don't try anything. Just leave me alone."

Mark grinned at her, "Have a good day at work Addison," he cupped her cheek and softly kissed the corner of her mouth.

Addison jumped as a loud noise sounded behind her. She looked up and saw Derek's retreating figure through a pane of trembling glass.

He had punched the shatterproof glass.

"Your a jackass," she seethed, storming into the hospital.

XXXX

"Derek," Addison called out as she walked briskly through the halls.

Derek turned and glared at her.

'So your not even talking to me?" Addison demanded.

"How's Mark?" he questioned icily.

"He's a pain in the ass," Addison replied, "You don't honestly think that I am with him."

"So you kiss everyone goodbye like that?"

"What is wrong with you?"

"Nothing."

"Dr. Montgomery-Shepherd?" a nurse at the station interrupted, "Dr. Sloan is on the phone for you."

"Better go," Derek glared.

"Tell him I moved to Poland," Addison instructed.

"What, is that code for 'Meet me in the supply closet'?"

"That's more of yours and Meredith thing isn't it?"

"Dr. Montgomery-Shepherd?" the nurse interrupted again, "He says to tell you that he is picking up groceries before he heads home. So if you want anything to tell him now."

"He is living with you?" Derek was livid.

"Of course not." Addison seethed, snatching the phone out of the nurses hand, "Mark if I catch you in my house one more time i am calling the police."

"You are unbelievable."

"He is not living with me. He is practically stalking me."

"I'm sure."

"Thanks Derek," Addison glared at him. "Seriously. I thought you knew me better then that."

Derek watched her storm away and fought with himself not to call her back and apologize.

He does know her better then that.

XXXXXXXXXX

Pour Derek. Men are actually crossing state lines to move in on his women. That's brutal.

I think I might give him a break in the next chapter. I've been giving him a rough time. OR I might finalize the divorce. It's all up in the air.

Next chapter: Callie and George question Addison decsion making skills.
