Dan: "Oh, shit. Are you guys back together? And what does this say about my relationship with Serena? And will I still be able to live here? Mostly the last one."
Rufus: "I was just bringing Lily something Ivy stole from her. It is called my dick."

THE STANDOFF

Bart: "Who is this loser that isn't calling you back?"
Ivy: "It's really not, like, that mysterious. Think about it."
(Lonelyboy: "Dear Charles, please come to PRADA where Lily has your documents. Love, Daniel.")
Chuck: "Fuck this, I'm out."
Bart: "Oh, gotta go take care of more of Blair's problems and act against your own interests like I'm always saying you do, but in fact you never do? And she always does?"
Chuck: "Yeah, whatever."

Bart: "I am literally going to kill you. How do you not understand this?"
Ivy: "Let's just stand here in our underwear for like a few more hours. I'm kind of at a loss."

POP-UP SHOPPE

Blair: "I am triumphant! My clothing has sold out, to teens! I sure hope this show doesn't kick me in the box like it always, always does whenever anything nice happens."
Serena: "Hang on while I give you the longest speech about how great you are, even though you've been a complete monster to me all episode and pretty much my entire life."
Blair: "You know what, I am sorry. I totally get why you didn't want me hogging all the guys, and why Dair was a huge problem even though it's the best thing that has happened in the last three or four seasons. I mean, if you'd ever made the circle complete and fucked Chuck, I would have gone ten times as crazy as has ever happened."
Serena: "First of all, I would never. He is disgusting. What am I, Jenny Humphrey that I am going to sleep with my attempted rapist? And second of all, obviously I know that. Obviously, I know that I get dibs on Dan and you were just being an asshole about it."
