- Charotte's mother: Someone, somewhere is out there living the life I should have had. Because I gave it away to the first man I met.
- Charlotte: We'll never get equality in the boardroom until we get it in the bedroom, will we?
- Jack: You know how long I've waited to meet someone like you? I mean, finally... finally a girl who doesn't confuse a bit of uncomplicated sex with all the romantic crap about commitment and love. I'd like a pound for every time I've been sucked into that particular hell.
- Alan: [about Jack, at the first dinner at the shared flat] He's hand-picked every one of us to conduct his social experiment.
- [First lines, voice over]
- Charlotte (Present Day): Someone said that death might end a life, but for the survivor, the relationship struggles on, seeking resolution it may never find. I suppose we should have guessed that the death of one of us would bring us back together. But none of us are under any illusion that time heals.
- Jack: What's the point of social mobility if we just carry the same tired old values around with us? So what we do is, we construct a model of living based on equality, based on the welfare of the group rather than the selfish needs of the individual. Up to and including... sex.
