Niles: Roz, you might recall you went out with him for six months. She's only seen him three or four times, they're not even sleeping together.
Roz: What? How would you know?
Niles: She told me. I don't want to be the bad guy here, but you did have him first and he did want to make a life with you.
Roz: Listen, there is no way that I am going... She hasn't slept with him?
Niles: She's English.
