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 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.
