A/N: I knocked this out in a couple of hours during a bout of insomnia. Let me know what you think and I'll carry on from there!

PROLOGUE

'Trust Casey to end up marrying someone she argued with at a baseball game.' Alex rolled her eyes. 'You know they went on their first date after she'd spent three hours shouting at him, and he invited her out for dinner so that she could shout more?'

'I did hear that but I thought she was joking,' said Olivia. 'Well, there's nothing like a marriage that starts with a bit of good old-fashioned hate sex.' She winked. 'You should know that, Alex.'

Alex blushed. 'Not everyone gets the perfect romance you had with Elliot...'

'Perfect romance?' Olivia burst out laughing. 'I got pregnant while we were both drunk at a work party, in an ancient on-call room bunk bed!'

'Well, yes, but we always knew it was going to happen with you two, it was just a matter of time.' Alex smiled. 'Trust you to have to go about things the difficult way.'

'Hey, I'm not the one who ended up committing a Class B misdemeanor in the courthouse men's bathroom with the defence attorney from the case you'd just finished prosecuting.'

'The guy was an asshole!'

'So you had sex with him.'

'Yes.'

'In a men's room bathroom stall.'

'Yes.'

'And later married him.'

'Well, yes...'

'After six months of ill-advised one-offs somehow turned into a serious relationship.'

'He turned out to be a nice asshole. And, well, what can I say, I'm quite fond of his assholery in court now. It's entertaining.'

There was a shriek from the other side of the room and they both looked up. Natalie and Alex's daughter Kimmie were playing tag around the tables.

'Natalie! Natalie, stop it!' Olivia rolled her eyes at Alex. 'I'm sorry, my child is terrorising Casey's grandparents again. I'll be right back.' She watched Elliot deftly intercept his daughter mid-run and scoop her up before she could frighten any more of the elderly guests. Natalie scowled. Somehow she had already managed to rip a hole in her new red velvet party dress. Olivia sighed. 'That girl, I swear...'

'Don't worry, I think Kimmie's just as bad.' Alex raised her voice and strode across the room. 'Kimmie! Kimberly Elizabeth Langan, you stop that right now!'

Kimmie stuck her tongue out at her mother and hid under a table as Elliot appeared, carrying their struggling daughter. Munch was a couple of steps behind him holding Natalie's long-forgotten party shoes. 'Liv, I think maybe it's time for Nat to go home.' Elliot sounded more than a little defeated. He could outdo a dozen suspects one after the other, but when it came to Natalie, she had him beat. And, even worse, she knew it.

'But El, Casey will be so disappointed if we leave before the end-'

'No, it's OK, I talked to Munch and he offered to take her back to our apartment and keep an eye on her until we get home. He's heading off now anyway. Apparently the last bridesmaid just rejected him.'

Munch nodded mournfully.

Olivia still looked doubtful. 'Well, if you're sure...'

Elliot was trying to stop Natalie from trying to climb up onto his shoulders. 'Come on, Liv, he is her godfather, and she adores him. Remember when he taught her how to swear in three different languages?'

Olivia shot Munch a dirty look. 'I do.' He gave her what was clearly meant to be an apologetic look. Olivia didn't buy it for a second.

Munch reluctantly gave up trying to look apologetic. 'Olivia, it'll be fine. She's four, she'll probably just go to sleep as soon as I get her home.' He took Natalie from Elliot and put her down, keeping a tight hold on her hand. Natalie promptly started jumping up and down.

Olivia tried her best not to laugh. Natalie never went to sleep without a fight. Not that she was about to tell him that now. 'OK. Thanks, John, I appreciate it.'

'Any time.' He squatted down to talk to Natalie. 'Hey, Nat, you want to come learn to play poker with your Uncle John?'

Natalie grinned and nodded enthusiastically.

'Good girl.' He stood up straight and led her out of the room, Natalie skipping happily along beside him. Olivia raised her eyebrows at Elliot.

'Come on, Liv, what harm can it do for her to learn some card games?' Elliot put his arm around her shoulder. 'Plus it means I get to spend some time with just you, and I never get to do that any more.'

'Well, aren't you sweet.' Olivia slipped her arm around him and kissed him on the cheek. 'Can you believe Casey got married? She's the last of our single friends...'

'Except Munch.'

'Yes, but that's Munch.'

'True.'

'Do you remember our wedding, Liv?' He smiled at her, wrapped both arms around her waist and pulled her in close.

'Of course I do.' She put her arms around his back and pressed her lips against his mouth.

Elliot smiled and kissed her upper lip. 'I loved that dress...' Olivia had chosen a cream and ivory floor-length dress with a pale gold pattern. 'Especially the... uh... the filmy divorce stuff.'

'Devore, Elliot.' Olivia tried not to laugh. 'Why would I choose a fabric called divorce for my wedding dress?'

'No idea, but God knows I've given up trying to understand women.' Elliot had learned enough over the years to know that, as the groom, all he really had to do was show up and try to remember to wear a clean shirt.

'That's probably wise.' She smiled.

He brushed a strand of hair back off her face. 'Do you remember when you threw the bouquet and Munch literally dived out of the way to avoid it?'

She laughed. 'Yes.' She'd actually thrown it in his direction deliberately.

'Do you remember when we snuck away after the speeches to go and sit on the roof and drink champagne by ourselves for an hour?'

She kissed him again. 'I do.' That was her favourite part of the whole evening.

He leaned in closer, kissed her cheek again and held his mouth right next to her ear. She could feel his breath on the side of her face. 'Do you remember the janitor's closet?'

Olivia blushed bright red. 'Yes.' OK, so maybe the roof was her second favourite part.

Elliot ran his hands down her back and began to stroke the sides of her hips with his thumbs. 'That was a really great way to spend a half hour, wasn't it?'

Olivia bit her lip. 'Yes.'

'Talking about it's got me wondering if there are any little places like that in this hotel that we could borrow for a little while...' He began to kiss her cheek and the side of her face.

She swallowed. 'Maybe we should go and find out.'

Elliot pulled away and tried and failed to look disapproving. 'But won't Casey be disappointed?'

'Screw that. We'll be back before she even knows we're gone.'

Elliot looked a little hurt. 'That's not really much of a compliment, Liv...'

'You know what I mean.' She smiled and kissed him. 'Want to go violate article 245 of New York penal law?'

He hesitated. No, he had to say it. 'You do know that technically this would count as entrapment, right?'

She rolled her eyes and began to lead him towards the ballroom doors. 'Shut up, Elliot.'

A/N: What did you think? (And for everyone who asked for more of the E/O, what can I say, ask and you shall receive. I adore you all.)
