After a run-in with an increasingly paranoid Bart (guest star Robert John Burke), Blair (Leighton Meester) grows alarmingly concerned for Chuck’s (Ed Westwick) safety. However, feeling confident that his father will never hurt him, Chuck makes a deal that could change his life. Wanting to make things better for Chuck, Blair devises a plan with the help of Serena (Blake Lively), Georgina (guest star Michelle Trachtenberg) and Sage (guest star Sofia Black-D’Elia) to try and get what they need out of Bart. Meanwhile, Nate’s (Chace Crawford) financial dilemma finally lands him in a place that he never thought he would be. Penn Badgley and Kelly Rutherford also star.
