I would never be that cruel to you...on purpose.

Hold it right there, Humpfreak.

I have been cordial to you for the last 52 minutes. Do you have any idea the psychological torture that I've endured being nice to you?

Blair: My Grace Kelly can defeat my Grace Jones.
Eleanor: Uh huh.

Dan: Hey. I love you. You know that, right?
Blair: I do now.

Chuck: After everything we've been through, there's no room for secrets. Nor should there be. Whatever it is, you can tell me, Blair. It's just us here. You and me.
Blair: I think once everyone is gone, and it's quiet, you need to go back into that house.

Jack: Whatever you saw or you think you saw, you can't tell Chuck.
Blair: Of course I'm going to tell him. He has a right to know. And there's nothing you can do that will make me change my mind!
Jack: This isn't about me. Do you realize how many people get hurt if this gets out? You need to go. You've already complicated things enough by being here. This whole thing was supposed to go off without a hitch. You better hope it still does.

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

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

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: 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.
