"Being a socialite was good enough for Jackie O," Blair twitters, and runs away before Eleanor can tell her to cut it out. Which is another facet of the dream, because think about how Eleanor is independently wealthy, both an artist and a cutthroat businesswoman, who married for love twice -- once to a homo and once to a Jew, neither of which are words the Archibalds can even spell -- and how it was her new money the Captain was pimping Nate out after last year. The Bass and Waldorf names don't amount to a whole lot, but they do amount to money, whereas the van der Woodsens of the world seem to be always running around penniless and marrying New Money so they don't starve. And then you've got poor Nate, who's like living proof of the fact that class has nothing to do with money, and acted exactly the same before the Captain as when he was homeless, and is still acting that way now that the van der Bilts are after him again.
But part of the reason Eleanor didn't have Jenny killed, after all, is because of all Blair's friends she's the only one that gets it. And she raised this sincerely intimidating, powerful girl on like this big gay Themiscyra island with Horace so that she could turn into Heather Locklear, not so she could be the next big celebutante. If any part of Blair understands that this is a seriously degrading step for their family to consider, it came straight from Eleanor, and the more Blair sinks into this weird Senior Year fog the angrier she gets.
Cyrus jumps in, offering to pull some strings to get her an interview with his friend JR, a "big mugwump" at NYU, which Eleanor loves, but Blair's mind is firmly set on this new stupid plan: "Well I'm sorry, but just because I lost Yale does not mean I'm wasting my time at a non-Ivy, reading Beloved six times and experimenting with lesbianism." She stomps off with a snotty "Nate is waiting," and Eleanor basically gives her whole socialite plan a huge classy middle finger, but it's too late.
