The only person as funny as Blair this week is Chuck, who starts out the episode so dejected that he makes a hot tub time machine reference. He finally gets his desire to rejoin the world when he gets wind that the Bass business manager has turned up dead after a mysterious accident, and he thinks he can link Bart to the murder. Mojo restored, Chuck becomes hilarious, antagonizing Nate and Sage while he looks for evidence. He stares at them while they make out just to bug them, and taunts Sage that "everything has really fallen apart" since she left. Man, this is Chuck Bass.
