NGTV Guide: Monday, November 23

Happy Thanksgiving Week! It’s time for our favorite shows to break out another holiday-themed episode; let’s see what kind of drama they can cook up alongside the turkey tonight.

Gossip Girl – the CW 9/8c
“The Treasure of Serena Madre” – It wouldn’t be Thanksgiving on the Upper East Side if there wasn’t a serving or two of some major drama for the holiday. Blair suspects her mom has been keeping a big secret from her, but it turns out to be something else entirely. Vanessa is supposed to spend Thanksgiving with her parents, but has a fight with her mom (guest star Gina Torres) and shows up on Dan’s doorstep. Rufus learns that Lily has been lying to him about her mother, Cece (guest star Caroline Lagerfelt). Chuck tells Nate that he has some potentially damaging information about one of their friends. Jenny learns that Eric was behind her very public embarrassment at Cotillion and can’t pass up a chance to get even. Serena is put in a very awkward position when her mother invites Trip (guest star Aaron Tveit) and Maureen (guest star Holley Fain) to join them for Thanksgiving dinner.

Castle – ABC 10/9c
“One Man’s Treasure” – When a murdered man is found stuffed in the garbage chute of an apartment building and two women arrive to ID his body — one his wife and the other his fiancee — Castle and Beckett have their hands full keeping the women from killing each other as they work to peel back the layers of the victim’s double life. Was it a jilted woman, corporate espionage, or a much darker secret that led to his demise?
