Chuck Bass: Maybe become a person someone could love.
Blair Waldorf: Someone did love you. And you owe it to her and everyone else you are leaving behind not to run away. Which is what you are doing. I don't think that great man you are talking about wanting to be is a coward. I think he would face up to what he did.
Chuck Bass: I destroyed the only thing I ever loved.
Blair Waldorf: I don't love you anymore. But it takes more than Chuck Bass to destroy Blair Waldorf.
Chuck Bass: You're world would be easier if I didn't come back.
Blair Waldorf: But it wouldn't be my world without you in it.
