"I have a question." Mark states while pouring himself a glass of very expensive orange juice the next morning.

Derek looks up from the TV, "Which is?"

"Why haven't we gone down to the casino yet?"

"Why haven't I gone down to the spa yet?" Addison asks as she enters the room post shower in nothing but a very short towel. Mark shoots Derek a look and then they both turn to face her. "What? You've both seen me in a lot less many times."

"But this is now."

"And I'm sorry, Derek but if you have a problem with looking a half naked woman, that's not my concern."

"That's not what I meant." Derek replies bitterly.

"I know but your reaction certainly brightened up my morning."

Mark stares across the counter at Addison, "What?"

"How are you not hung over?"

Derek laughs, "Addison can hold her alcohol better than anyone. It's actually kind of scary."

"But she--"

"Drank an entire shelf full of alcohol, I know."

"And now Addison is cheerful, and wants to go lay out by the pool."

"Addison is also talking in third person."

"Addison thinks Mark should leave her the fuck alone."

"I don't know, Mark, the pool kind of sounds like a good idea."

"What are you, a chick?"

"No…"

"What are you talking about...? OH!"

Addison rolls her eyes, "Yes there will be hot girls in bikinis, now let's go."

"You're in a towel."

"Right, be right back."

"It's like one hundred and ten degrees out here."

"Literally."

"I want to go back inside." Mark whines, "There are no hot girls."

Addison coughs.

"Except you, of course."

"Better."

"What time is it?" Derek asks, attempting to see all the way across the pool to the clock on the wall but failing.

Addison reaches down and checks her phone, "Eleven thirty."

"I'm hungry."

"Let's eat."

"Where?"

"Room service?"

"Deal."

Addison walks into the kitchen/living room area of the suite holding up two dresses. "Should I wear the red one to dinner, or the black one?"

"The red one."

"You're only saying that because it's shorter and lower cut."

"And?"

Addison turns her head, "Derek, what about you?"

"The red one, but only because I think you'd look beautiful in it." Derek says, half sarcastically and half sincerely.

"See now he has the right idea, you we need to work on." Addison tells Mark before leaving the room to get dressed.

Mark turns to Derek, "What?"

"You just told your ex wife she'd look beautiful in a red, sparkly dress."

"To be fair, I didn't say the sparkly part."

"Whatever."

xxxxxxx

"I'm ready."

"Thank god. It's only been what?" Mark turns to look at the clock, "Two and a half hours."

Addison walks into the room.

"And somehow I just forgot I was angry about the time." Mark says in awe.

"Whatever, let's just go."

Derek hands Addison her purse and Mark puts a hand on her back, guiding her out of the hotel room.

Maybe the next five days wouldn't be so bad after all.

"Name please?"

"Mark Sloan."

"Okay, Mr. and Mrs. Sloan and..."

"Derek Shepherd."

"And Derek Shepherd, this way please."

"Oh we're not, we're not married."

"My apologies, Miss."

Once they sit down Addison says, "I can't believe he thought we were married."

"You look like your married."

"How?"

Derek gestures down to the fact that their hands are intertwined. Addison's face turns red at the realization of it and drops her hand from his immediately. "Sorry."

"Are we getting wine?" The waiter asks as he approaches the table.

"Yes." All three of them answer together.

"Okay, glass or bott-"

"Bottle." Once again, all three of them answer.

"Alright then."

"Can you believe this?" Addison asks, after a moment of silence.

"Believe what?"

"This. That we're all here, together."

"I keep thinking it's a horrible nightmare I can't wake up from." Derek says, bluntly.

"No one's tried to kill anyone yet, that's good."

"It's only the second day."

"True."

"Do you remember the last time we went to Vegas?"

Mark laughs, "How could I forget? You and Derek kept me up all night. That is the last time I'm getting a room next to a couple unless I'm sure the walls are soundproof."

Addison blushes, "We were crazy back then."

"Yeah I remember you snuck into the O.R. to have sex and I had to guard the door for you. Then the chief came and asked me what I was doing alone in the hallway--"

"And you said you really needed some time to be alone and all the on-call rooms were occupied." Derek says laughing, "I remember."

"He never looked at me the same again."

"I bet."

Silence.

"What happened to us?"

"We became us."

"That makes no sense."

Addison shakes her head, "It makes perfect sense."

"Let's watch a movie."

"Fine but Addison's not allowed to pick."

"Hey…"

"Let's watch the ring!" Mark says, grinning.

"Scary." Addison says backing up closer to Mark's lap.

"Okay."

Mark orders the movie and then takes his place back on the chair. Within twenty minutes, Addison is in his lap and hiding her head in his chest.

"It's not that bad, Addie."

"Are you kidding me?" Addison screams.

"Fine."

At the end of the movie Mark whispers, "Addie, it's over."

"I think she's asleep." Derek tells him.

"Yeah, she is."

"Want me to help you move her?"

"No it's fine, I'll stay here."

"You sure?"

"Yeah."

"Alright, good night Mark."

"Night, Derek."
