He stares off into space as they embrace, thinking about throttling her.

SPECTATOR

Bart: "I just dropped by to point in your face and laugh all evil. Since Ivy slipped my grasp and Lily burned up all that 'microfilm' I don't really have a shitload else to do."
Nate: "(Quite the high-minded outrage, for a number-fudger.)"
Bart: "Oh, did you think I was done blackmailing you? I'm just getting started. Don't forget I also have a nefarious scheme we don't know anything about, which will ultimately prove Chuck's vindication. Until then, your ass is mine."
Nate: "My ass is always somebody's, I guess."

THAT BAR

Blair: "I won! I won fashion! Let's have a fête at the atelier!"
Chuck: "As insufferable and ill-deserved as that sounds, I'm afraid I can't ever be with you because Lily broke my heart and now I will never be a Powerful Woman like you."
Blair: "Uh, that works out, actually. Since your obsession with Bart was the only reason you wouldn't marry me to begin with. Can't we just say fuck it?"
Chuck: "Stop lying to yourself. I am a failure! Please. Just go. Do not look upon my monstrous visage! We are NEVER EVER EVER GETTING BACK TOGETHER."

She takes that ring the hell away from such pronouncements and runs off to cry and not be any fun at her party. But one wonders if she gets any comfort from the fact that they all say this exact thing to each other so very often that they're now having conversations about how they all say this to each other all the time. If it were me, I would think about that to the exclusion of all else. "On the one hand, quite a setback. On the other hand, if it walks like a dubious cliché and talks like a dubious cliché..."

BACK IN BED

Serena: "Whoo! Good thing we're oblivious to the misery of literally everyone else on this show, even though we were party to it. I'm a lot happier being here back in bed with you, having apologized eleven times to people who don't really deserve it."
Dan: "I'm just happy Nate and Chuck aren't mad at me anymore. Or my dad."
Serena: "Oh, do they count? Because they weren't even mad at me. How funny, we started this relationship thinking everybody was mad at both of us, but really I had just been dumped and my best friend is a volatile hag. Really the only person everybody is mad at is you, and for totally valid reasons."
Dan: "Go get me some champagne and try not to think too hard about reasons everybody including you should hate me forever and ever."
