Cameron has vanished for dinner with his rugby team, which Chuck -- of all people -- finds "homoerotic." B says obviously that's what she's into, vide every guy she's ever dated, and they both look fantastic, in their party clothes. Chuck Bass will wear the shit out of a tux. So Jenny shows up and lies and says she didn't get the proof and hides it deeper in her purse and hopes that Lily drops dead, because that'll show 'em. "Watch out, Lonelyboy. Seems your little sister has her own ideas about your family's planning..." GOSSIP GIRL WHAT DO YOU MEAN.
Okay, party time. But instead of actually doing anything, let's talk about it for a long time and explain this whole stupid goddamn plan. The best part of this is that they are all terrified of Serena, who is there like this blonde specter haunting them with her presence. And the reason is that you don't do this shit to Serena. It's the only thing that bugs her in this entire world is when you do this stuff to her. So Nate and Dan are bringing a Dr. Tabb over from Mt. Sinai, because he's on the AMA board and can threaten Holland with delicensing if she doesn't explain herself to the satisfaction of these children.
They give Jenny this doctor's ticket and Blair's phone, and she immediately dials up Ortho at Mt. Sinai -- a number she just knows -- to say that Dr. Tabb doesn't need to come to the benefit after all, because it would suit her better if Lily died. Serena spots Jenny and her breasts, and makes a mean face and calls Rufus to tattle on her, because she is grounded. Serena is just out to get old Jenny this week. Meanwhile, Chuck and Blair bother Holland with their relationship, and somewhere in there of course it turns into a bit of a real therapy session, which leads directly to the gaywaddest thing in this whole episode, which we will get to in a bit.
Rufus appears and says needless words about why he is there: "Serena called me, but I was already on my way! I figured if my grounded daughter goes missing, I just have to wait till the next big party to know where to find her!" Jenny promises that she's trying to help him this time and it's not what it looks like. It never is, dear, but also: She's not trying to help him! She's trying to help his wife die!
