It’s SAT crunch time for our favorite prep schoolers, but vocab words aren’t the only thing on their mind as Georgina Sparks is back on the Upper East Side. And the anticipated debut of Michelle Trachtenberg‘s trouble-making character did not disappoint.

First, Georgina convinces her reformed friend Serena (Blake Lively) to blow off a study session with her beau Dan (Penn Badgley) so they can catch up over cosmos. The next night, G promises S they’ll stick to soda if she’ll just go to dinner with her for an hour, but then she drugs her friend when she’s not looking. Serena blacks out – and misses the test.

The secret nights out are leaving a strain on Serena and Dan’s relationship, but when Serena tells Georgina not to contact her anymore, G brings up something secret from their past:

OMG! Will Serena be forced to tell Dan about Georgina? Too late! G is already making her move on Dan.

Meanwhile, Blair (Leighton Meester) may be slowly retaking the throne, but will seeing Vanessa (Jessica Szohr) and Nate (Chace Crawford) together be a distraction? Or will operation “Get Nate Back” start soon?

Favorite Fashion Moment: Serena’s coveted Burberry Warrior bag and leather Rag & Bone leggings. If Serena is going down with Georgina, at least she’ll look good doing it. Her It bag is on the top of every fashionista’s must-have list and the asking price is more than $3,000! The leggings have yet to hit the shelves of Bergdorf Goodman, but when they do, you can get a pair for a mere $1,440. –Andrea DeSimone

Tell us: What happened last year that Serena won’t talk about? What do you think of Nate and Vanessa?
