[He wasn't fully forgiven. Not by a long shot. But Booker recognized that, and was trying to make it up to her. But simply the fact that he'd told her he loved her, that he'd, of his own free will, taken her into his arms and kissed her, spoke volumes.]

He gave me away because he loved me. He thought giving me to Comstock would give me a life I could never have had with him. He's never forgiven himself for it. He said I was his debt. That I couldn't just be wiped away.

I know it sounds suspect, but... Booker DeWitt is my father. He tried to give me Paris, but he's given me a whole new world.
