Author's Note: Someone asked for a chapter about Maddek having fun in New York, this is it :)

Thanks for asking because I had so much fun writing this chapter! Well, at least the first part haha. Anyway, I hope y'all like this chapter as much as I did. Enjoy!

Disclaimer: I own none of the songs used in this chapter.

By the way, the title is a song from The Lumineers, I think it fits Mark's POV in the second part so perfectly I want to cry.

New York, 1993

"Another one, please", Mark asks the bartender, pointing at the empty cup in front of him.

The door opens and Derek and Addison walk into the bar.

"What about Sam and Naomi?", Mark inquires.

"They're not coming", Derek responds.

"What do you mean they're not coming? We need to celebrate!"

"They said they're very happy too and they would be here if they could but they need to stay home with the baby", Derek continues.

"Man, they're skipping all the fun these days".

"They have a newborn", Addison points out. "They have priorities now. Looks like it's going to be just the three of us for a while".

"Alright then", Mark shrugs. Then he gives them one of his famous grins. "I hope you're ready to have fun tonight because we're officially residents now!"

"Damn right we are", Addison smiles wildly.

"Yeah", Derek grins too. "Just don't get too drunk because I'm driving and I don't want to watch you two act crazy. It's not fun if I can't act crazy too".

"We don't need to be drunk to do crazy", Mark claims. "We're not interns anymore, we're like real doctors now! We're crazy enough already. We're like drunk in happiness".

They spend some time at the bar until it's late and Derek asks if they want to go home.

"Are you kidding me!?", Mark raises his eyebrows. "Of course not".

"The bar's closing".

"Well, then let's go somewhere else", Addison shrugs.

"Okay", Derek shrugs too, grabbing his keys. "Where?"

"I don't know. Does that matter?", she smirks.

Mark looks at her, impressed. "Have I ever mentioned how much I like the drunk version of Addison?"

"I'm not that drunk. I'm just freaking happy".

"If you say so", he teases. "But yeah, lets do this, we'll find somewhere".

Derek can't say no, because he is excited too.

Minutes later they're in the car, Mark on the backseat, the night pleasantly warm and the city very much awake.

A song comes up on the radio; it only takes two seconds for Mark to recognize it and he can't help but sing along.

"Jessie is a friend", he begins. "Yeah, I know he's been a good friend of mine".

"But lately something's changed, it ain't hard to define", Addison joins him, turning her head slightly from the passenger seat, and he has to repress a laugh because she's a terrible singer. "Jessie's got himself a girl and I want to make her mine".

Derek smiles as if he can't resist joining them. "And she's watching him with those eyes", the three of them are singing now. "And she's lovin' him with that body, I just know it! And he's holding her in his arms late, late at night".

"You know I wish that I had Jessie's girl!", they hit the chorus.

"You guys realize this is a weird song for the three of us to be singing, right?", Derek jokes, raising his eyebrows.

"It would be, if it was you and me and anyone else, but Mark? Ew. That would never happen", Addison teases. "Not in a million years".

"Hey", Mark protests. "I'm offended", he jokes, fake hurt.

But for one second his mind works faster than he would like and he tries to picture him and Addison in a romantic way. He looks at her differently - black dress, red lipstick, the wind messing with her hair but somehow she still managed to look beautiful - for one second, and then it's gone. He doesn't feel that way about her. She's his friend.

The next song comes up, and he realizes that maybe they would have to say goodbye to their vocal chords that night, because there's no way they wouldn't scream Livin' On A Prayer out of their lungs. Now he is actually laughing; first, because he haven't had that much fun in a while; second, because they are ruining the song, especially Addison. But Derek is looking at her like her lack of singing skills is actually the cutest thing in the world, and Mark feels the urge to roll his eyes because his best friend is acting like a fool, but he also feels the urge to smile. He's happy for them.

"Can you believe this is really happening?", Addison turns off the radio after a couple more songs, against Mark's protests. "Four years ago we were Med students. Remember our fist week? You know, I met you guys on my first week of Med School and I had no idea you'd become such a big part of my life".

"I take it back", Mark teases, "I just remembered drunk Addison can be way too emotional".

Derek laughs, and Addison rolls her eyes jokingly . "I'm having a moment here, you two asshats", she teases back. "Fine, moment's passed".

"Good", Mark smiles. "Now let's go find a party".

Seattle, 2005

It's been months, but the feelings are still there. Still intense. Still strong enough to keep him awake at night. Still not gone when he sleeps with other women. The feelings that tormented him and propelled him to get on a plane to Seattle.

She didn't answer any of his calls, but word spreads fast. He knew she and Derek were back together, even though he'd had a thing with an intern. But he needed to try. Because if he didn't try, he would never stop thinking about what could have been if he had fought for her, and it would eat him alive.

Of course going to Seattle also meant that he would have to face Derek. It wouldn't be easy, but he knew that day would come sooner or later. He also had the tiniest hope - he knew it was impossible, but he couldn't help it - that maybe Derek would forgive him and things could go back to the way they were before this mess.

But forgiveness doesn't come with a punch in the face, right?

He guesses he deserved that.

Funny thing is that he is almost sure he got punched for hitting on the famous intern - old habits die hard -, not for sleeping with Addison. As if Derek is in love with Meredith. And here comes hope again. Maybe Addison would give in. And Mark would be there, waiting.

But she keeps telling him to go back to New York. He also discovers that she didn't tell Derek about the two months they had spent together. How can she expect to make things work if Derek doesn't love her anymore and their relationship right now is mainly based on lies? He desperately tries to make her see that there's no way that will work. Why does she insist on seeking love and happiness where she won't find it? Why does she keep pushing him away when just wants to make her happy?

"You're marriage is over, Addison", he says softly, later that day. "All you have to do is admit it".

Then he does one more desperate attempt. He asks her to meet him at the bar across the street.

And he waits.

"She won't show, you know", Meredith tells him, showing sympathy. Or maybe empathy, like she has been on that situation before.

"What if you're wrong?", he refuses to let go of hope. "What if just this once life comes down on the side of the dirty mistresses?"

But she was right. He waits. And waits. And waits.

Addison doesn't show up.

As if life wanted to punch him once more, Jessie's Girl starts playing on the jukebox. You've got to be fucking kidding me, he swears to himself, paying for the drinks and leaving the bar immediately.

No matter how much she wished things to get easier, they just seemed to get harder.

She should have known she couldn't avoid it forever. She couldn't hide from it. Even if she tried not to think about it, even if that subject hadn't come up between her and Derek for a while, she should have known that she would have to face it eventually, that all the history and pain the three of them shared now wasn't forgotten.

She didn't want to face it, but the truth was still there, everywhere, surrounding her, ambushing her, until she couldn't escape it. "He's not in love with you", Mark had told her, "He's in love with that intern and he's not even trying to hide it". And then again in the elevator, when he claimed that her marriage was over. And then when he touched her, causing the feelings she had buried to resurface instantly, until she's left alone in the elevator, heart racing, taking deep breaths in order to control the tears and to keep her own mind from driving her insane.

Everything is a huge mess.

But still, she can't run from it. She still can't give up on her marriage.

"Can we talk?", she asks Derek the minute she's in the trailer.

"I don't want to talk to you right now", he answers sharply.

So, just like many times in their last months together in New York, they don't say a word to each other until the next day. And it sucks, because not talking means they can't face the truth together, and they will keep living a lie.

Note: So, I used two songs in this chapter and I don't know if you guys know the first one (it is on that movie 13 Going On 30, if you ever watched it). It was actually funny, I was just thinking about what song they could possibly be singing and this song popped up in my head and I was like "holy shit, that's it". It just fits their story lol. (Plus, I know the scene I wrote is set in the '90s, but I think they'd have more fun with songs from the '80s, since in the '80s they were teenagers).
