michelle trachtenberg getty 'Gossip Girl': Michelle Trachtenberg to return for long term arc as Georgina SparksFanemies (fans of TV show bad guys, a term we just coined) of Georgina Sparks (Michelle Trachtenberg) have new reason to rejoice. The Wicked Witch of the Upper East Side is coming back to “Gossip Girl.”

TV Line is reporting that the actress will return to the series for a significant arc starting with the series’ 100th episode. That show is set to air in early 2012.

The program’s executive producer Josh Safran says, “Her arc is unlike anything that she has done before on the show. Of course, she still is Georgina and all that implies, it’s just taking that in a new direction.”

It’s all but assured that Trachtenberg’s arc will have some thing to do with Charlie/Ivy (Kaylee DeFer) and Serena (Blake Lively) given their past. And who knows, maybe she and Dan (Penn Badgley) will patch up their sizable differences and make a go of it.

Uh oh. Uh oh.
