S and Blair, still on the outs, negotiate to have Sage walk in the show, which seems pathetic for a number of reasons. Is this really the one thing keeping Serena's relationship with Steven afloat? Does she not see how sad that is? Also, Serena throwing a fit over her and Steven's fashion show seating is so very Real Housewives of New York City. The two girls snipe at each other, and when Sage strips down to her underwear on the runway, Blair and Serena both look bad. Sage is certainly devious, but for all of Gossip Girl's intoning that Sage is trouble, her little underwear trick seems pretty tame compared to what S and B used to do to each other when they were in high school.
