- [at the concert, Annie, the chef, offers Martin and Louisa a tray of canapés]
- Dr. Martin Ellingham: Not for me, thanks.
- Annie: Go on, they're delicious.
- Dr. Martin Ellingham: [unaware that he's speaking to the chef] Salmonella en croute, made yesterday by unwashed strangers - no thank you.
- [after the concert, Louisa leads Martin into the woods. They kiss passionately]
- Dr. Martin Ellingham: [breaking off the kiss] You're very emotional, Louisa.
- Louisa Glasson: Sssh!
- Dr. Martin Ellingham: What?
- Louisa Glasson: You're not obliged to spoil it, you know.
- Dr. Martin Ellingham: Are you wearing perfume?
- Louisa Glasson: Yes.
- Dr. Martin Ellingham: Is it sandalwood?
- Louisa Glasson: No. It's Kenzo Flower.
- Dr. Martin Ellingham: I wondered whether it was pheromones. Androsterone-5 has a sort of sandalwood odour - faintly urine-like, if you prefer. It's the pheromone associated with the onset of the menstrual cycle, and it's often accompanied by mood swings.
- Louisa Glasson: Urine-like?
- Dr. Martin Ellingham: Yeah, it's only faint. Am I right?
- Louisa Glasson: A woman doesn't have to be getting her period to be a bit emotional.
- [Louisa walks off in a huff]
