"Don't you mean you and Constantine? Or did you forget, the same way you forgot to say good-bye to me and Eric every time you left?" Lily begs her not to do this, acknowledging the issues she may be having with new-dad Bart but asking politely that she not also sabotage their entire debut. "What? I'm not doing anything. I thought we were just sharing memories of what a close family we are." Ariel's cherubic face lights up with Schadenfreude. "I remember this one time, um, when I was eleven, Eric and I wanted a White Christmas. Luckily, mom's husband was a raging cokehead, so he left blow everywhere..." Lily laughs so she doesn't barf, and even Eric's down to admitting that it was a shitty way to grow up: "It wasn't everywhere -- just on the smooth, shiny surfaces."
"Was that, um, German Klaus with a K, or Danish Claus with a C? I can't ever remember which ones she actually married, or ... which she just decided were more important than her children." Lily stares down at the scary monster her daughter has become and Serena finally gets it: "You know what? I was wrong. It's not Bart at all, it's you." Lily nods, grasping the other half that Serena hasn't figured out, meaning they have the entire equation but they don't know it yet. "Looks like the Bass housewarming party just got a little colder. Serena's walk down memory lane has her heading out the door..."
Vanessa and Chuck take a turn around the party before she heads off to the bathroom or something and he sips his champagne. Blair appears with total game face, having decided on the next phase of her wild plan: "Bet's off." Chuck knows he's got her, and complains it's not over, but now B's the one claiming boredom: "You were right. Vanessa's not worth playing with... Pursuing Vanessa is beneath us both." Chuck thinks he gets it but he doesn't: "Why the sudden change of heart? ...You think I'm going in for the kill. You're worried you're gonna have to go through with what you promised!" Exactly wrong. Exactly 100% precisely wrong, not that B even knows that for sure yet. "I'm not. ...Worried... About... That." Chuck smiles and asks what the problem is, and she runs off in a huff, because she doesn't know either, but she's starting to, and it disgusts the part of her that doesn't know the difference between pretending and being. He watches her go, and I think the most touching thing about all of this is that he still takes her at her word: she says she doesn't want to fuck him, he's going to try and work that angle, because she's such a blunt and brutal force of nature that you don't even think to be like, "OR! Is the OPPOSITE true?"
