The Revengers

S6 E9: After a run-in with an increasingly paranoid Bart Bass (recurring guest star ROBERT JOHN BURKE), Blair grows alarmingly concerned for Chuck's safety. However, feeling confident that his father would never physically 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, Georgina (recurring guest star MICHELLE TRACHTENBERG) and Sage (recurring guest star SOFIA BLACK-D'ELIA) to try and get what they need out of Bart. Meanwhile, Nate's financial dilemma finally lands him in a place that he never thought he would be.
