Elizabeth: I saw how much you loved him. Your strength...
Walter: Not strength! Hubris. And I've been punished for it ever since.
Elizabeth: By whom?
Walter: By God. By a deity, whatever you want to call it. And I understand, I deserve it. No man should do what I did.
Elizabeth: You made a mistake. That's what being a man is.
Walter: It was more than a mistake. I broke universes. I asked for a sign of forgiveness, but I got nothing. There is no absolution for me.
Elizabeth: Well, I don't believe that. I forgive you, Walter. I forgave you a long time ago. And if I can, God can.
