Blair doesn't care about Charlie's dumb plans or his childish attempt to be bad-ass; she just wants him to feel his feelings and be sad today so she can do for him what they do for each other. But Charlie's not having it; he's no longer satisfied with the successes of his Empire and wants to branch out. She scoots her bulimic form through the elevator doors sideways, determined to stay at him until he bleeds grief, and that way she'll know she's being a good girlfriend.
Lily is fumbling and wrestling and chucking bags and coats left and right in that closet where she drunkenly hid herself at Thanksgiving, and eventually stashed THE LETTER in Maureen's coat while Maureen was wandering her home for hours and hours unattended. Rufus is all excited about some stupid co-op meeting because he barely gets out of the house anymore because he hasn't discovered his place among the trophy wives and yoga ladies and doesn't even know a good prescriber or plastic surgeon's name yet so he has no social capital. He can tell Lily's fretting about something, probably her whore daughter, and offers to represent her at the meeting -- which Lily is both grateful and nasty about, because it's not like he has anything else to do and she's sort of starting to hate him.
She realizes how she just ground his manhood into the cement PRADA floor and turns it into lauds for his commitment to their family that apparently takes up all his time... Which would be fine except she's not busy -- her professional life seems to be basically signing things a couple times a week in the comfort of her home -- and their children are: 1) A business magnate who lives in an honest to goddamn castle, 2) Tramping around Long Island having been evicted from the house, 3) Living both in DUMBO and NYC. Leaving 4) and 5) who are respectively a drug dealer and Eric van der Woodsen, who was raised by wolves and is doing just fine without their asses like always. So the question is really what the fuck do either of them do all day, besides chase each other around the house whining suspiciously?
On Lily's agenda today is locating THE LETTER and getting 6) Rufus out of her hair for five seconds so he doesn't figure out whatever terrible thing she's done this time. That's all she's got going on. So she literally puts his coat in his hands, pats the top of his stupid head, and sends him out to do a nonsense job that even trophy wives consider stupid. Then she sighs, because self-destructive and mysteriously busy all the time is a lot of work.
