Chuck: I returned it because you asked me to let you go. I wanted to move on to give you a happy life you deserve.
Blair: All this time I've blamed you. For pulling me into the dark. But I was wrong. It was me who brought out your dark side. And now that I'm with Louis I've done the same to him.

Chuck: You never pulled me to the dark side, Blair.
Blair: I appreciate you trying to make me feel better, but I have my answer.
Chuck: You're the lightest thing that ever came into my life.

Dorota: Uh oh. Mr. Chuck in dream again.
Blair: When Chuck's in them they're all nightmares.
Dorota: What he do now?
Blair: Behave like a perfect gentleman. Which makes him even more chilling. That fake apology of his has permeated my subconscious and haunts me even when I sleep.
Dorota: Apology not seem so fake to me.
Blair: That's because English is your second language!

Blair: Grab the bread. Not even Chuck's media mind games could disrupt the calm I feel off feeding the ducks. Besides, you could use the exercise.
Dorota: I'm pregnant too, remember?

Blair: What are you doing here? Our treaty of 2010 clearly states the duck pond is my domain. {Monkey whines at her} Don't try to fool me with your puppy dog eyes.
Chuck: I apologize for the intrusion, but your web-winged friend here waddled into the dog park and was about to become a labrador's lunch.
Blair: And out of the goodness of your heart you came to his rescue.
Chuck: I like Duck a l'Orange as much as the next person, but it seemed cruel to let the poor creature suffer.
Blair: Especially in front of a photographer. What a lucky duck.
Chuck: I've imposed on your domain long enough already. If you'll excuse me, Monkey needs his constitutional.

Blair: How much more do you need to see?
Dorota: Of duck pond? Not really my thing to begin with.

Blair: I can't rest until I can prove Chuck is still his satanic self. What do you think would be more effective, having his shirts pressed with too much starch or getting him served blended Scotch at the Empire bar?
Dorota: What is test testing exactly?
Blair: We'll be there—in clever disguises of course—to see him eviscerate the dry cleaner. Or fire the bartender. Thus proving that he's only pretending to be magnanimous when I'll be there or see it in the press.
Dorota: You sure you not just do this because you and Prince Louis not in a good place right now?

Serena: Why are you looking for Chuck?
Blair: I have no choice! He's trying to destroy my relationship with Louis because he knows it's vulnerable.
Serena: I'm pretty sure the only war Chuck is waging is with his own demons.

Blair: Do you remember when we used to play dress-up?
Chuck: How could I forget. Though I didn't think this was your kind of entertainment anymore.

Dorota: The same thing happening to me. Pregnancy makes fingers swell up like kielbasas.
Blair: Well the paparazzi aren't camped out downstairs to find out if your wedding is called off. If they see me without my ring they'll think it means something.
Dorota: I start to think maybe it does.

Blair: I plan on having my child the old-fashioned way: fully sedated. And the only Downward Dog I want to see you doing is cleaning up the dust from under that couch.

Gossip Girl: I guess it's time for me to accept that if you want something badly enough you have to go out and get it yourself.
Dan: Hey, I was wondering what you were doing today.
Blair: Coming to stay with you, actually.
Dan: Uh... okay.
Gossip Girl: Watch out, kids. The end of me just might turn out to be the end of one of you.
