I've recently heard the quote ...
Question: I've recently heard the quote "Your mother, your daughter" on both Gilmore Girls and Grey's Anatomy. I read somewhere that it was from a movie, but I can't remember which one. Can you help me out?
Answer: The line is actually "My daughter, my sister, my daughter, my sister, my daughter," and while I couldn't swear that it has cropped up in Grey's Anatomy, Lorelai definitely said it on Gilmore Girls. It's from Chinatown (1974), and [SPOILER ALERT] it's from the scene in which detective Jake Gittes (Jack Nicholson) finally shakes from treacherous, near-hysterical heiress Evelyn Mulwray (Faye Dunaway) the awful secret that has blighted her life: father-daughter incest. Mulwray's teenaged daughter is also her sister.
