J.a. London said this quote
“ He turns to leave, stops, looks back at me. Just so you know: What you did for Victor means a lot to us. You could have left him to die.No, Richard, I couldn't.I see in his eyes that he understands. I didn't save Victor because I knew that his being alive was best for Denver. I gave him my blood because I didn't want to live in a world without him in it. ”
