"S?" says Blair, and Serena comes down, assuring them it's all right. She leads Dan a few steps away. He is very angry, and very hurt by all of this. Nearly crying, he just stares at her: "What's happening?" Man, I have never felt worse for the kid. She won't meet his eyes. "Something is going on, and I just want to be let in on what it is." She tries to tell him it's hard to explain, but he makes it "easy" for her: "I know you're keeping something from me, and I'm sick of being the only one you don't talk to about it." She swears she's not talking to anybody about it -- in fact, she's gone out of her way not to -- but Dan's too freaked out. "Then what are they doing here, while... While I get a call from a bartender who says you left a bar at two in morning with a bunch of guys?" She looks down but he's on a roll. "What guys, Serena? Who... Who were they?" She answers, truthfully, that she has no idea. Which doesn't sound great, granted, but he's leapfrogging here anyway.
"Did something happen last night?" She begs him not to go on, and do the whole nine, and tell himself the whole story, because whatever it is -- and she knows what he's thinking -- it's better than the actual drama. But he's not stopping. "Is that... Is that what you're so afraid to tell me? That you cheated on me? Did you cheat on me last night? All I need is a yes or a no, did you sleep with someone else?" She nods, without looking at him. "Yes. Yeah." Blair, Nate and even Chuck continue to feel horrible. Dan tells her twice that he's done, and gets on the elevator; Serena is so very sad. Didn't take him too long to get there at all, no, but he is fairly heartbreaking this whole episode.
Sarah calls as the doors close. "Hey! Did you find Serena?" He takes his time admitting that he did, but admits he wishes he hadn't. "That doesn't sound so good. I'm just in the park. Wanna meet me? Maybe talk about it. I'm a pretty good listener. ...Dan?" Of course, that's just what he needs.
Lily charges out of the Palace with Bart and the planner barely keeping up: "Well, I wanted cymbidiums, not hyacinth. And why did we choose fish? It's unseasonably warm. You know, I knew we should've gone with the Limoges instead of the Lenox..." (Always go with Limoges.) Bart's like, "Everything was cool and now you're finding fault with everything, like, are your feet cold in those strappy sandals, or...?" Lily assures him nothing is wrong, but she's already had "three perfect weddings," and wants this one to be "more perfect than perfect." Her phone rings -- it's Blair's house.
