The Long Goodbye
This week’s episode title, “The Wrong Goodbye,” comes from the 1973 noir film The Long Goodbye. It stars Elliot Gould as Philip Marlowe, a private detective caught up in a deadly plot. It’s probably somewhere in that Netflix queue Dan (Penn Badgley) and Blair (Leighton Meester) are sharing.

Cecily Von Ziesegar
“Have you met our distinguished alumna Cecily?” Headmistress Queller asks Serena (Blake Lively). “We’ve never met, but I’ve read a lot about you,” Cecily says. Too true! “Cecily” is Cecily Von Ziesegar, author of the Gossip Girl books. Foolish Headmistress Queller should know better than to introduce an author to her creation. She’s lucky the universe didn’t implode.

Jonathan Karp
When Vanessa (Jessica Szohr) decides to betray someone, she goes straight to the top. She sells Dan’s book to Jonathan Karp, who’s a fancy editor at Simon and Schuster. He heads up swanky imprint Twelve. If you want to steal someone’s memoir and sell it, you should definitely bring it to him.

The Horah
That super-fun-looking dance that Chuck (Ed Westwick) and Blair were doing at the Bar Mitzvah? 1. We’ve done it. It is, in fact, super fun. 2. It’s a traditional Jewish dance called the Horah, usually done at weddings and Bar and Bat Mitzvahs. 3. The chairs usually hold the guest of honor, not some random goyish couple nobody knows. 4. No matter how much you want to reach over the dancers’ heads as they lift you and hold hands with your soul mate in the next chair over — do not do it. You will fall out of the chair.
