Finally Back to Best of Blair!
27 February 2009 | by silver_randomocitySee all my reviews

In the past episodes, Blair has been the good helper girl, something unusual of her character. But this episode has proved that the old manipulative Blair hasn't gone anywhere. When Blair decides the new teacher Ms. Carr has given enough grounds to extract revenge, Blair recruits her friends to help her. To extract revenge, Blair posts a rumor about Ms. Carr, which jeopardizes Blair's future. But Blair's isn't the only future jeopardized in the ordeal.

In another plot line, Chuck is trying to find a mystery girl and secretive club he vaguely remembers and learns some information he never knew before. Nate and Vanessa appear alongside Chuck for some light humor and fluff.

A very Gossip Girl episode full of manipulative Blair and inquisitive Chuck and hits nearly every character on the ball and never fails to entertain.
