Lily and Bart start their first dance together as Blair approaches the very adorably smug Chuck. "That was quite a speech. All your hard work must have paid off." He dances her onto the floor, and admits he was inspired in the moment. "Look, I know I said some horrible things, even for me..." Blair points out some of them, including when he "blogged to Gossip Girl" (these kids today!) and compared her to a sweaty old horse, and he's like, "What's your point?"
"What's yours?" she asks, and he says, with the weight of truth: "You don't belong with Nate." And then he whispers -- and I admit I kind of gasped -- "Never have, never will." Man, that's tight. Even better is her response: "You don't belong with anyone." And they kiss, and it's a little sad but mostly awesome, and the ice is getting thinner. Serena, on her way out, spots them kissing and gives a great drive-by WTF, thereby unavoidably smacking right into Lonelyboy. They get super awkward and he says he's looking for Vanessa so they can go. Nobody but Chuck knows that she's probably got Nate tied up somewhere demanding more and more of his personal information because she's a nosy parker with no sense of boundaries, so they try to duck away from each other, but just then the twitchy wedding planner swoops in again.
("When the flows under our feet bled into the sea / And nothing was left for you and me...") He pushes them out onto the floor for photo ops, demanded by the bride and groom, and won't take no for an answer. There's a truly, truly horrible series of flashes as they both wig out, I mean it's really awkward and demeaning, and they're staring into the flash bulbs as they go, and the guy's like, "You're gonna want to remember this night (flash!) forever, yeah?" He pushes Dan into her arms and they start to dance. This is like Hostel! It's so awful! What a great scene! Dan quietly apologizes to her, but she goes into van der Woodsen mode, buttons up, goes dead: "Just smile."
