The music in this episode is brilliant in at least three places, of course, but this is one of them. The following speech, her cadence and intonation, give every indication of an imminent bursting into song that never quite occurs. There's even like a hint of the ghost of a memory of a Cockney lilt lurking in the basement of her phrasing here, which -- no shit -- verges on iambic. Leighton Meester's instincts are, as ever, infallible; Blair's are, as ever, tone-deaf.
"I'm aware I lack some people's easy grace
With strangers. And I don't exactly make
You feel like you've known me forever
Even though we've just met. When I laugh,
You might not smile just at the
Coquettish sound of it. And I
May not be "spontaneous" or
"Delightful" or "full of surprises," and
My hair might not sparkle when it catches
Realizing her voice has been getting more and more crazy and aggressive throughout that little trip through verse-ville, Blair shudders. "...Everything worth knowing about me is in that folder," she says sadly. "I made sure of it." Which is exactly why she needs Serena, even when she feels water-boarded by it: because Serena knows all the things outside that folder, and wants more than anything to make Blair understand them.
Outside, Blair and the Dean shake hands, equally disappointed, and Blair tries several times for an invite to the night's secret reception, but he's not bending. And then, in one of the most indelible images from the novels, Blair awkwardly swoops in on him and pecks him on the cheek, just entirely out of her mind and reaching for an appropriate behavior that is not there. He jumps out of his skin, Shirley's eyes bug out, and Blair immediately worries that she's going to throw up. The Dean retreats to his office immediately, and Blair quietly prays for death.
Outside Admissions, Serena's cracking up about "Great Hoaxes In Archaeology" with some lovely friends she's only just met, drawing her in to show her the course catalog through sheer force of delightfulness. Her hair sparkles blindingly as Blair rushes her, scattering the underclassmen back to their garrets and hidey-holes. "What are you doing, Serena?" S plays it off, of course, so Blair has to say it out loud. "No, here. Yale. Yale is mine!" Serena admits she was only visiting to punish B for her outright bitchitude that morning, and B's like, "Consider me fucking punished," but Serena stops her in her tracks: "...I actually like it here." It bounces thuddingly against the back of Blair's head like a thrown handbag, and she whirls back around, stricken.
