Blair: Your transformation really is astounding. Case to share how you gave up your bad Bass ways. How you went from Charlie Sheen to Charlie Brown? Bar to mitzvah?
Chuck: There really is no answer to that question. It's an evolution.

Namaste. I'm sorry to interrupt you getting into someone's yoga pants.

Blair: I need this time to figure out what went wrong with Louis and right it.
Dorota: Maybe he Freaky Friday with Mr. Chuck. They struck by lightning at the same time or pee in the same fountain.
Blair: That's incredibly unsanitary.

Blair: I still love Louis. I just want to marry the sweet Prince who returned my Vivier slipper and made me believe in fairytales, not one of the Brothers Grimm.
Dorota: Even Prince Charming can fall off horse.

Blair: Why should I thank someone for a blender? Do I look like the kind of girl who makes margaritas?
Dorota: Oh, margaritas sound delicious. But six months away at least.

Blair: I hope never giving up on people isn't going to be my downfall.
Chuck: That's why you're going to be an amazing mother. You're always there for the people you love. Even when they don't deserve it.
Blair: You know that's never going to change.
Chuck: It's okay if it has to. Starting tonight I'm going to take care of myself.
Blair: Is that all?
Chuck: Yeah.

Chuck: I'm sorry for losing my temper the night you told me Louis proposed to you. I'm sorry for not waiting longer at the Empire State Building. I'm sorry for treating you like property. I'm sorry I didn't tell you I loved you when I knew I did. Most of all I'm sorry I gave up on us when you never did.
Blair: Thank you.

Blair: Then what are you here to apologize for?
Chuck: Everything else.

Blair: What are you doing here? I don't have the energy to rehash tonight's hysterics. I think you should leave.
Chuck: I'm not here to apologize about what happened tonight.

Louis: The paternity test showed me that some part of you thought you might still have a choice to make, and I needed you to see that Chuck would always be the wrong one.
Blair: Louis, I don't now how many more times I can say this, but Chuck and I can never work.
Louis: You know that for certain?
Blair: I do. So does he. And so should you. Chuck destroys everything and everybody in his life. And he'll never change. But what's scaring me is that you're changing into him.

Louis: How was your day?
Blair: Just what I needed. Old habits die hard.
Louis: If they die at all.

Blair: Dressing me for my wedding day means attending to my every need, no matter how big or small. Adjust for reception! Cinch that train! Penelope! She has to pee!
Dorota: Where secret wedding location?!
Penelope: We don't know!
Dorota: Who designed Miss Blair dress?!
Jessica: We can't tell you that!
Blair: Good one Jessica. Now block that baby bump!
