Wharton-grad VP Raina Thorpe approaches Chuck and tells him he looks dapper, and then she introduces him to her boss and father Russell, and Chuck is thunderstruck by all of this at once -- falling into lust with her now that he knows she's a Thorpe -- to the degree he somehow misses the criminal ugliness of this sentence: "I said I prefer the term secretary, which I do for those whom it actually refers to." (Like I said, usually only GG and Blair mangle simple language like that usually, so it really sticks out, but also: Well done, Wharton.) I mean, I fuck up grammar all the time on this beat, but usually it's to make you laugh, and I don't think this was a conscious thing or else they'd never let Blair do it, of all people.
Anyway, gist: Russell is not only not Lily's secret buyer but also hates Bart for screwing him over so bad he ended up in Chicago, and would like nothing better than to do exactly what Lily was afraid a hostile buyer would do. I hope precisely that does not happen!
Lily says pointedly that she didn't expect Dan to be there, and we continue further down this weird Thorpe trope (thrope) where their taste level is constantly being called into question. I know it's supposed to be about Chicago Money v. UES Money (and thus link them up eventually with the Vanderbilts v. Archibalds class thing we're looking at), and it's entirely possible it was blind-casted like they do on Grey's, but still. Considering they're the only black people in NYC, it comes off a little unnerving. You gotta weigh the "we have black people on our show now!" against the "...and they are gross!" and see what comes out on top.
"Are you kidding? There are actually beers behind the bar I can pronounce," Dan says. Which again: How's that? Yes, there's the funny hipster deal where sometimes your man-of-the-people Defiantly PBR Thing gets mixed up with your man-of-the-world Obscure Foodie Thing, but the way you avoid that cognitive dissonance is by not saying it out loud. Although Lily's been surfing the shores of that bullshit since she ran away to Hollywood in her spin-off episode, so I guess it's valid to say it to her.
Lily realizes that Dan's there with Serena, because her Spidey-sense of impending debacle just started thrumming way loud, and then Eric sits down with the tux after all, grinning like the meanest little minx. "Hi, Mom! So sorry I'm late, but I couldn't find my cufflinks! So I just borrowed the ones that Judge Stephens left at the Palace!"
