Blair: Just because you’re dressed poorly doesn’t mean you’re not Chuck Bass.
Chuck: Why would I want to be him?
Blair: You should have told me you got shot.
Chuck: I’m surprised you didn’t shoot me yourself.
Blair: I have, many times, in my dreams, the good ones. But if you were really hurt I would want to know.
Chuck: When I woke up my ID was gone. Nobody knew who I was; nobody was coming to look for me. I realized that I might be alive but Chuck Bass doesn’t have to be.
Blair: Changing your name doesn’t change who you are.
Chuck: It’s a good start; a chance to live simply, earn people’s respect. Maybe, become a person someone could love.
Blair: Someone did love you. And… you owe it to her. And everyone else you’re leaving behind not to run away. Which is what you’re doing, and I don’t think that great man you’re talking about wanting to be is a coward. I think he would face up to what he did.
Chuck: I destroyed the only thing I’d ever loved.
Blair: I don’t love you anymore. But it takes more than even you to destroy a Blair Waldorf.
Chuck: Your world would be easier if I didn’t come back.
Blair: That’s true. But it wouldn’t be my world without you in it.
