Edith: Now you're happy again, you'll be nicer... for a while. Mary: If that's what you feel, then why are you here? Edith: Because, in the end, you're my sister and one day, only we will remember Sybil... or Mama or Papa or Matthew or Michael or Granny or Carson or any of the others who have peopled our youth... until, at last, our shared memories will mean more than our mutual dislike.
Edith: The one thing Mary can't bear is when things are going better for me than for her. Bertie: I'm sure that's not true. Edith: You don't know her. I'm getting married and you've lost your man. And you just can't stand it. Tom: Edith, there is no need for -- Mary: You're wrong. I'm very happy for you. And I admire you, Bertie. Not everyone would accept Edith's past. Tom: Mary, don't.
