Andrew Wyke: Whether I love her or not, I found her. I've kept her. She represents me. Once, she was in love with me.
Milo Tindle: And now she's in love with me. And you can't forgive that.
Trivia: Marguerite Wyke was "played" by Joanne Woodward, the wife of Paul Newman. Woodward's likeness was used for Andrew's painting of Marguerite, and the actress listed as playing her was a fictional name.
