Chuck:I can’t let my feelings cost me all I’ve built. Blair:Even if it means losing me instead? All I ever did was love you. Chuck: The worst thing I ever did. The darkest thought I ever had. You said you would stand by me through anything. This, Blair, is anything. Blair: I never thought that the worst thing you would ever do would be to me. Chuck: You went up there on your own. Blair: Goodbye, Chuck.
