Last night's 100th episode of Gossip Girl gave us plenty of drama, tears, nods to the past, surprising twists and a couple of new enemies. We broke down the pros and cons of this wild, controversial installment in our review of "G.G." and will analyze it much more in our weekly Round Table discussion later this afternoon.

Looking ahead to next week, runaway bride Blair must make a difficult decision about her future, the consequences of which could hurt those she loves most. Needless to say, she's up against it with Louis.

Can she, with the help of Chuck and Dan, formulate a plan to help her escape her husband? And what role will Gossip Georgina, who smells the scent of scandal and decides to follow its trail next week, play?

From the looks of the trailer, she and Dan are in an airport at some point, with Mrs. Grimaldi still in her wedding dress. Not exactly an inconspicuous look when you're on the lam, but she had little choice.

Meanwhile, Serena takes the blame for an incident with Gossip Girl in order to protect someone she loves. Think that means she'll claim she sent out the blast? Or something else? We want to know your theories.
