Dan takes the stage to introduce Bart, but at the last minute he decides to introduce someone else: Chuck. Apparently Chuck managed to escape the jet before it crashed, and in a desperate attempt to expose his father he tries to convince the audience that Bart was behind everything (yes, Chuck's reappearance also means that he will probably be getting back together with Blair ... again). But unfortunately, security escorts Chuck offstage and Bart manages to calm everyone down by claiming that Chuck has a problem with substance abuse. In the midst of the chaos, Serena tries to slip out to catch her flight to L.A. Blair intercepts her at the door, and in the usual S to B heart to heart, Blair tries to convince Serena that there's enough room for both of them in New York and Serena insists that the only way to reinvent herself is by moving away. Deja vu, anyone?
