"I'm so embarrassed," Blair chokes out. Shame is the immune system of the game they've been playing, but it's more than that: nobody wants the embarrassment of being seen. And she has spent her whole life hiding, so that nobody would see that girl. She shows her teeth so often, so the film stays on the projector, so everybody will believe the movie, about Blair's perfect life. The awful shame of realizing that not even her will -- the thing that literally keeps her alive, the thing that couldn't save Serena, or Eric -- can keep the burlesque going, once somebody peeks behind the curtain. There aren't any words: "I'm so..." Serena smiles. "So what? Start over. It can be done. I should know. We'll get through this together." They promise, and embrace, and there are so many words in Serena's eyes, and Blair has no words. She calls off the pilot and the handlers and looks into Serena's eyes.
"One good scandal deserves another. Wonder who's going down next? Everybody, if B has anything to say about it. You know you love me. XOXO, Gossip Girl."
There's so much love, and fear, and strength between them, as they hold hands and look out over the water, but there aren't any words left. There are no words for free-fall, because you don't talk when you're falling. All you can hear is yourself, falling. Ask Serena, who's about to teach Blair the biggest secret of all: she's not falling. She's dancing.
