Title: Never Been Marcused
Air Date: September 8, 2008 at 12:00 AM PDT
Chuck befriends Lord Marcus in an attempt to figure out how to undermine the Lordship's relationship with Blair. The identity of Marcus's mother comes out—yes, it's Catherine, the Duchess—and Chuck attempts to use this to his own advantage. His plan is foiled when Blair walks in on Nate and Catherine getting it on and immediately dreams up a blackmail scheme. Nice try, Chuck, but Blair is a tough catch. In the middle of this mess, Nate and his mother run into financial troubles, and Catherine proposes a scandalous solution. Finally, Dan and Serena steam it up in unusual places.
