Also, if you read this chapter and then listen to Somewhere Only We Know, you might shed a tear haha.

Anyway, enjoy!

New York, 1994

There has been a ton of speeches about the newly wed couple - some were cute, like Naomi's; others were touching, like Carolyn's, who said Derek's father would be very happy if he was there; others made everyone laugh, like Mark's, who told a lot of funny and embarrassing stories about the two of them, but who also looked very happy for them; even Bizzy's and The Captain's speeches weren't that bad.

By the time everyone who wanted to say something is done, Derek himself gets up from the table he and Addison are seated and heads to the dance floor.

"So", he starts, "I want to say something too. But it's going to be a different speech. I wanted to do something different", he notices Addison looking curiously at him and he smiles at her. "I've worked on it for the past week. I hope you like it."

He makes a sign for the guitarist and starts singing.

Our eyes met over the cadaver

And I knew I had to have her

Everyone starts laughing, including Addison.

Had his mitral valve gotten too thick?

Is that what made our cadaver so sick?

"What are you doing?", he reads Addison's lips, while she's furrowing her brow. But she's also smiling, and it encourages him to continue.

Addison Montgomery, he met her in the summer, she

Was cutting up a very dead body

And in her eyes I saw my life

I knew that she would be my wife

And she would breath the life back into me

For every day until eternity

Or until I'd be as dead as that body...

Everyone applauds, but he barely notices, because he's looking at her. She's still laughing, but she's looking at him with so much love, and she looks so beautiful tonight, more than any other night, that it's impossible for him to look away.

"Alright", he continues, "I declare the dance floor open."

Everyone exclaims excited words and many people head to the dance floor while he goes back to his table.

Addison immediately gets up and pulls him by his arm, leading him out of the room, running pretty fast for someone who's wearing a long dress and high heels.

"We need to go while it's a mess in there so no one will notice we're not there", she explains.

"Where are we going?"

"Just wait for it."

They take the elevator, and she presses the button to lead them to the highest floor.

When the door opens, she guides him to a stair and suddenly they are in the rooftop.

"Are we even allowed to be here?", he raises his eyebrows.

She shrugs, smiling defiantly.

"I found this place last week, while you were talking to the manager."

"You said you were going to the bathroom", he accuses her.

"Because it was a surprise", she shrugs. "I wanted to find nice place with a nice view, so I could surprise you in the wedding day."

It was a nice view. It was a beautiful view, with the city lights dancing in front of their eyes.

"I don't have a speech in my head - or a song. But I've got this."

"I guess we're good at surprising each other, aren't we?", he smiles.

"Yeah", she smiles back. "I still can't believe you wrote me a goddamn song", she laughs.

"You're worth a goddamn song. We're worth a goddamn song."

Seattle, 2005

It's getting dark outside, and she's had particularly stressful day, so she enters the on-call room, and she is surprised to see Derek in there, seated on the bed.

"Oh", she apologizes. "I didn't know you were here."

"It's okay", he responds, and she notices he doesn't look fine.

She closes the door behind her and sits on the bed beside him. "Crappy day?", she asks.

"Yeah", he sighs. "You?"

"Same."

They spend some seconds in silence, until he speaks again.

"A had a patient today who almost died", he comments. "Car accident. We looked for his family, but turns out he didn't have any family, except for his girlfriend, who was the closest thing he had to a family. So we called her, and she came and asked him to marry her."

"Oh", it was all she managed to say.

They stay silent again for a few more instants, before Addison sighs.

"What went wrong between us?" She asks.

He looks at her, and she continues. "I mean... Before the cheating, before that whole mess. We had loved each other, so what happened? How did we end up here?"

He sighs. "I don't know", he shakes his head, sadly, and she realizes he's been asking himself that same question. "I guess we'll never know exactly. Maybe that's just how life is, you know. We're doctors, we know that sometimes things go wrong and we don't always know why. We can't always find an explanation. Sometimes shit just happens, and by the time we notice it there's nothing we can do."

"Yeah", she sighs too. "Yeah, you're right."

"I'm sorry it ended up the way it did. I'm sorry I wasn't a better husband."

"I'm sorry I cheated on you. I screwed up."

"We both did", he shrugs.

"Well", she gets up after a minute. "I should go now. See you tomorrow."

"Alright."

She heads to the door.

"Addie?", he calls her softly.

"Yeah?", she stops, turning around.

"Thank you", he smiles. "For all those years."

"You too", she smiles back.

She heads to the door again and opens it, but she turns around again before closing it, with another smile on her face. "Yeah, you know what? Those nearly twenty years? They were worth a goddamn song."
