Author's Note: See, I said you wouldn't have to wait too long for this chapter, didn't I? I'm actually a little bit impressed with myself – less than a week between updates! Thank you for the reviews on the last chapter, I know I say it every time, but I do mean it, and I honestly never stop getting excited to see a new review sitting in my inbox. Just so you know, I may be a bit busy now until after the New Year, so I'm stockpiling chapters; the next two are already written, and I will be releasing them at various intervals.

The London Eye, in case anyone hasn't heard of it, is a gigantic ferris wheel (although calling the London Eye a ferris wheel is a similar sort of thing as calling Marks and Spencer's a supermarket) that was put up for the Millennium on London's South Bank and has remained there ever since. It's a pretty spectacular addition to the skyline. By the way, I'm loving the Marks and Spencer's love! It's my greatest weakness, especially Percy Pigs!!

It was gone ten o'clock by the time Alex was finally finished in the OR and felt happy enough with the situation to leave his registrar to finish closing up. They had been correcting a duodenal atresia, but you could never tell when even a reasonably straightforward surgery was going to get complicated, especially with babies, and there had been a few scary moments when he couldn't find a bleeder that had made his heart race.

He scrubbed out carefully, watching through the window at his team finishing off. They were good, and he felt proud of the way they were coming along. He still couldn't believe, occasionally, that he was here. He was working at one of the most renowned hospitals in, well, the world really, and he was building a name for himself. He thought back to when he'd been a med student and read papers by people with names like Mark Sloan and Derek Shepherd (he had to admit he'd never read one of Addison's back then – a fact that he'd more than corrected since) and being impressed by their knowledge, that if they said something, it was considered to be correct on the grounds they had said it.

He might not be quite there yet, but sometimes, when Michael had dragged him along to some meeting or networking event, he saw a flicker of recognition in people's eyes when he was introduced to them, and he realised his reputation was beginning to precede him. Which was probably solely down to Michael, but still, it felt good. And he had to admit, he felt… proud of himself, which wasn't something he'd ever really experienced before. When he told Addison, she'd smiled, and kissed him, and told him that he had a lot to be proud of.

Addison. They'd been together for two weeks now, and so far, he hadn't screwed up. In fact, he'd been doing rather well, he thought. He'd orchestrated four dates, the best of which had been a bottle of champagne and two glasses smuggled onto the London Eye, and all of which had been successful. He'd forgotten how well he and Addison got on with each other. She was easy to talk to, quick and witty, and they found that despite the long estrangement, they still knew each other well, and somehow seemed to have the comfortable intimacy that only time could bring. And he'd never, ever been happier, never thought that this sort of happy even existed.

That wasn't to say, of course, that it was going to be all plain sailing. Ever since she'd arrived in London, Meredith's pregnancy had been weighing on his mind. He wasn't sure that Addison had a right to know as such, but if he knew, then she certainly should as well, but he was reluctant to broach the subject. If the truth be told, he was scared. He was scared that he would tell her that Derek was having a baby with someone else, and he would see regret in her eyes, and his underlying belief of being her second choice (or maybe even third, after both Derek and Sloan) that she was gradually eroding would be confirmed once and for all. But in the end, he'd decided he couldn't not tell her, so he'd taken her to the park and broke the news as gently as he could, hoping and praying that it would be okay.

She'd stopped walking, and went very still for a moment, then a smile lit up her face. 'Really? That's lovely news, they'll be fabulous parents.'

She'd sounded genuine, but he'd scanned her expression for any signs of hurt. 'You're not…'

'Upset? Hurt?'

'I don't know, I guess. Are you?'

'No. Not in that way at all. That was all a long time ago, and we're all happier now than we were before, so… And I mean it, Derek and Meredith are the sort of people who should have children, they really will be great parents.' It was her turn to look at him deeply. 'What did you think I was going to say?'

'I genuinely didn't know. But I'm glad that's the way you feel.'

She'd rested her head on his shoulder, and he put his arms around her, firmly pulling her into his embrace and holding her against his chest.

After he'd scrubbed out, he stopped briefly at the nurses' station on his ward to check there was nothing that he needed to attend to before he left, and had a quick chat with the parents of the duodenal atresia baby, reassuring them that the procedure had gone well and their son should be back in the NICU soon.

He'd then gone back to his office to call Addison before he left. When he got there though, the light on the answering machine was flashing. He played the message while he was putting his coat on.

'Three days in a row I've called you, and no answer. Either you're avoiding me, or you've actually gone and got yourself a life. In which case, you should be telling me all about it. Call me, I'm at work.'

He looked at his watch. Izzie probably deserved a call back; it had been over a week since he'd last spoken to her, but he should be leaving really. Then he reasoned he was late anyway, and in the unlikely event Addison had actually cooked dinner it would already be pretty much ruined. Which didn't really matter; he was too tired to be hungry and would be more than happy with a beer and just being with her.

He dialled the number of the main surgical department line at Seattle Grace, and asked for Izzie. It wasn't long before she came to the phone – must be a quiet day.

'Hey,' he said.

'Where've you been? I was beginning to think you'd dropped off the face of the earth.'

'Stop exaggerating, it's only been a week since we last spoke.'

'Well, I've been calling at the usual time for three days and you never pick up.'

'Sorry, I've been crazy busy.' Which was true, although on one of those evenings he had actually managed to leave at the end of his seven o'clock shift in plenty of time to take Addison out to dinner.

'At least you're calling now I suppose. So what's your news anyway? You sound different.'

'Different?'

'Happy.'

'Not a crime, is it?'

'Not for normal people is isn't, but these last few years, I've been beginning to think that you see it as one. You sound as if something really good has happened to you.'

He thought about what she was saying for a minute, and realised that while she might not be wrong, there was something else. She sounded the same. 'So do you,' he replied.

'What?'

'You sound different too, happy different. Who is he?'

'I asked first.'

'Well, I don't have a he who's making me happy.'

'But you do have a she?'

There was no way he was going to tell Izzie about Addison yet, partly because he was really tired, and couldn't cope with the high pitched squeal that he knew would come. But he also knew that her suspicion had already been raised, and he had to tread carefully. 'There sort of is someone,' he said, trying to keep his tone casual. 'I met her at work, but it's nothing to get excited about.'

There were a few small squeals. 'Ooh, I want details.'

'There aren't all that many yet, it's really early days.' Well, that wasn't exactly a lie. It was early days in that way, he and Addison hadn't even… yet. 'But I promise that you'll be the first to know when there's something to tell. What about you? Who is he?' he asked again, hoping he'd done enough to keep her off his back for a little longer.

'All right, I'll let you off for now, on the grounds that I'm so pleased that you followed my orders and got a girlfriend that I'm not going to punish you by grilling you about it. But if I don't get to know about yours, I don't see why you should get to know about mine.'

'Because you're dying to tell me Izzie. I can hear it in your voice.'

He could almost see her rolling her eyes at him. 'He's a teacher, fifth grade. Called Jason. And that's all you get.'

'That'll do for now. Look, I hate to cut you off, and I know I owe you a proper phone call, but I have to go.'

'My my, aren't we keen to be gone when we've got someone to go home with?'

'Pipe down.'

'By the way, talking about home, have you got one yet? Or are you still living in that hotel?'

'I'm still in the hotel. I've told you before, I like it there.'

'Alex, for God's sake, you can't live in a hotel.'

'I'm hanging up now…'

'Fine. Now take care of yourself.'

'You too. Good luck with Jason.'

All right, you've got me. The title 'Be careful what you wish for' was the giveaway really, wasn't it? McMuffin is right, there may be the patter of little footsteps on the way in the next story.
