N calls up Blair to talk about his dad's sudden coke habit, and gets this cute message in response: "Hey, it's Blair. I'm sorry I can't come to the phone right now, but I'm getting ready for the Masked Ball. See you tonight, if you recognize me. Which you won't." He mumbles around a bit and shows us that he is freaking out through the power of mumbles.
Jenny drops off the last of her thousand trials and labors and Blair is very sincere in her thanks, because you have to be nice to the help, because they are crafty and can smell fear. She continues the fratty stuff about how lugging giant gowns is part of Jenny's "education," which, I like the Dangerous Liaisons thing they always do there so much, and then notices the bracelet. "Vintage, right?" She compliments the diamonds on looking like diamonds, and Jenny excitedly explains about how the guy loaned it to her. Blair takes a second to figure it out, and then goes simultaneously steely and genuinely sympathetic: "Oh! Oh, sweetie, you didn't think you were gonna be able to come tonight, right?" But freshmen don't go, and that's tradition. OMG just as in the prophecy of Rufus, foretold in these very webpages, when he compared her to Cinderellas of yore! Jenny offers the weak explanation/apology that she went stupid for a second about this because there were five dresses for four people, and she made the mistake of thinking Blair was human and liked her especially. "You always need backup. I mean, what if I spilled something? Or a zipper broke?" Jenny thanks her for those helpful household tips and flees, hating the world and all the things in it.
