Kathy: (via the letter) I suppose, unless I live to a really exceptional old age I will be long gone as you read this. Don't feel sorry for me. I have led a good and full life. I've loved a good man and have been well loved in return. You would've liked Ben. He was the very first person I met in 1920. (flashback to Kathy's first appearance in 1920)
Kathy: Are you following me?
Kathy: You're going to stop following me?
Ben: No, I don't think so.
