A sneak preview of "Blair Waldorf Must Pie," the ninth episode of the first season of Gossip Girl. A naive Dan, trying to be a smooth operator, invites Serena and family over for dinner!
Nate brings a drunk Serena to get cleaned up in a flashback of the previous year. They get into a water fight with the shower head. Blair checks on them... and gets hosed down herself!
The kids are talking about the Rufus-Lily dating revelation from earlier that Thanksgiving Day. Blair is equally surprised by the garage door in Dan's bedroom.
Blair is completely playing it off (please, she knows why Serena's asking her) when Serena asks about Chuck! Then Blair gets really defensive when Serena questions her judgment.
