PARIS: You’re Juliet. You’re the best public speaker here, you’ve definitely got that waif thing down, and you’ll look great dead.
Paris chooses Rory because of her “waif-like” appearance, and because she’s supposedly the best public speaker out of all of them – which is good, if she’s hoping to be a reporter like Christiane Amanpour. Unfortunately, when we subsequently see Rory speaking in public, she doesn’t quite live up to the hype. As Juliet is lying down and either dead or looking dead in this scene, public speaking ability doesn’t seem greatly needed anyway.
