Kate and Alice in “The Rabbit Hole”

[narrating] Luke was right, Bruce. Gotham needed something to believe in. They wanted hope just as I started to lose mine. I spent half my life looking for my sister, and today, I found someone else, someone I didn't know or recognize. For the first time in fifteen years, I felt something other than hope. I felt doubt.

[narrating] It may have taken you years, sweet, darling Kate, but you found me eventually; even if I'm not the girl you expected me to be. I had my secrets just as you have yours. But do be careful, my dear sister. Putting on that suit and all the darkness that comes with it... makes you just as crazy as me.
