Elizabeth: You know, I never actually opened your letter.
Lucas: I had to explain where I was going and why.
Elizabeth: I had a feeling I knew what it said. You were blaming yourself for any danger you might have caused Jack and me with Walden, and you were doing the same about the mine potentially reopening, and with the sale of the oil company, you were feeling unsure of what you'd do next in business.
Lucas: You knew all that without reading the letter. Next time, I'll just save the stationery.
Elizabeth: When I asked you if you'd changed your mind about us, about our future together, for some reason, I was doubting what I know about you, and I realized there's no need for me to ever doubt you.
Lucas: Well, I feel the same way about you, but thank you for the reminder.
Elizabeth: To me, you aren't what you do, nor are you the sum of your possessions. Even if you'd come back and all of this had been gone, burnt in the fire, there would still be love.
Lucas: Making me the richest man alive.
