As soon as Abby and Greg leave, Sienna sees a change in Rob. The alcohol is beginning to wear off, and there’s nothing left to drink. Sienna is sure there was one more bottle of red, but she’s searched everywhere and can’t locate it.

‘Sorry, we’ve run out,’ she tells Rob.

‘Don’t worry. I’ve probably had enough anyway.’ His eyes dart to the door then to his phone.

‘She’ll be fine,’ Sienna says. ‘Stop worrying.’

Rob’s face reddens. ‘I’m not. I’m just—’

‘Wondering why we did this, now that it’s actually happened?’

‘Something like that,’ he admits. ‘Sorry. No offence to you.’

‘Oh, none taken.’

‘It’s just that I’m not the kind of person who… does things like this.’

Sienna knows this is inevitable – one of them was bound to get cold feet. She’s surprised, though, that so far Greg hasn’t. The fact that he left with barely a glance back chills her, cements in her mind that she needs to do something to fix the cracks before they are beyond repair.

‘I’ll make coffee and we can chat a bit if you like?’

Rob follows her into the kitchen and stares through the doors where, outside, the gazebo lights are still on, dotted against the black sky, highlighting the mess she’ll have to clean up tomorrow. She tries to focus on this moment; she wants Rob to enjoy himself, so it’s important she puts him at ease. ‘Greg’s really fond of you,’ she says, spooning too much coffee into two cups.

‘That’s good to know. I like him a lot. How long have you two been married?’

‘Four years.’ She smiles and wonders if Rob would prefer to hear that they’ve been married for ten or more. Would that make their marriage appear more solid? Or would that make either one of them more susceptible to cheating? ‘Not as long as he was married to Holly.’

‘So that’s the ex-wife then.’

‘Yep.’ Sienna chuckles. ‘She who must not be mentioned.’ More laughter.

Rob’s face is blank.

‘It’s from Harry Potter,’ she explains. ‘Don’t tell me you’ve never read it, or at least seen the films? How is that possible?’

‘I thought that was for kids,’ Rob explains, but at least he’s smiling now.

‘Not at all. Anyway, we’ve all got an inner child in us somewhere, haven’t we?’

‘You’re probably right,’ he says.

‘Here,’ Sienna says, handing him his coffee. ‘Drink this and sober up. We don’t want you embarrassing yourself, do we?’
