Ivy: How do you know this will work?
Blair: Do you think this is the first time I've entrapped someone with prostitutes?

Blair: Thanks S. You really are my best friend.
Serena: I love you, B.
Blair: I love you too.

Serena: Think it's time to tell Dan how you feel about him?
Blair: He told you about that? I'm not ready. I really want the next person I say it to to be the last.

Dan: Do you really want to spend the entire summer with me in Rome? Chuck's dad is alive. That is going to change his world deeply.
Blair: His, yes. But not mine.

Dan: I understand why you did what you did today, but I need to know for me — for us — what is really happening here.
Blair: There is nothing I want more than to spend the summer right by your side.

Blair: You know after my theatrics at the Young Lions Club, it's time I quit my moping. And get back in touch with what it truly means to be the Blair Waldorf.
Dan: That's right. OGB. Original Gangsta Blair.
Blair: Exactly. I need to find that Blair again. And what better place to look for her than at the Met, surrounded by some of my favorite paintings.
Dan: You better not meet any princes this time.
Blair: You don't need to worry, believe me. I'm done with fairy tales. It's time to be real again.

Blair: Chuck. I don't have time for any of your nonsense. I have a very busy day planned.
Chuck: Blair, listen to me please. I have this book. It's written in code and I desperately need to crack it. I remembered how good you are at things like this. Or at least you were. Maybe that was the old you.

Blair: Apologies. I just needed a few minutes to get into character. If you want to think like Diana Payne, you have to become Diana Payne. {in a British accent} Cheers. Thanks a lot. You're adorable. Spectator.
Chuck: Regardless of whether we find Jack, I can't tell you how glad I am at this moment that Diana isn't really my mother.
Blair: Hand me the book.

Chuck: Looks like we might have a lead thanks to Blair's powers of observation.
Blair: But unfortunately the entire clue trail hangs by the flimsiest of threads. Nate's long term memory.

Blair: Did you find your inspiration?
Dan: Yes. But the only problem is it's in Rome.

Chuck: Diana lied to me. She's not my mother. I think she's covering for my father. Well, my real father Jack.
Serena: Chuck, I'm so sorry. I didn't know.
Chuck: That book is the only chance I have at tracking Jack down.
Serena: Well what can I do?
Blair: Be with us, not against us.
Serena: You have me, one hundred percent.

Blair: What just happened? What did you tell him?
Jack: Tell him what?
Blair: What you're really hiding here.
