['Gossip Girl' - 'The Big Sleep No More']

Ah, a masquerade, a staple of CW storytelling and a delicious excuse for all manner of identity-switching shenanigans; it was only a matter of time before 'Gossip Girl' exhumed their stock of fancy facewear and started a new scandal or two.

The episode had more than a passing resemblance to last season's masked ball outing, 'The Witches of Bushwick,' another installment in which Serena and her fabulous blonde locks were the subjects of identity theft. (At least this week's episode didn't see her roofied and unconscious in a grimy motel in Queens.)

Diana proved herself to be a master manipulator capable of rivaling even Blair Waldorf, while our stubborn Queen B. found herself too fixated on Chuck's nonexistent scheme to recognize her own feelings.
