Get ready for the return of the vintage Season One Blair Waldorf Monday.

That's what Gossip Girl executive producer Joshua Safran and his writing colleagues are promising, at least, in Monday's episode, "Despicable B." In his weekly preview segment, Safran teases a "very fun story" in which something is written about Blair in a magazine and she goes to great lengths to prove the publication wrong.

Elsewhere, Lily sets out to change the family reputation because a money fight is the worst thing ever for their image, but may actually damage it more as a result ... not a big surprise there.

Chuck and Nate, meanwhile, grapple with the awkwardness of this week's big reveal. Now that both of them realize Nate's been sleeping with Chuck's mom, it's just uncomfortable all around.

Check out some "Despicable B" clips and their commentary below ...
