'Gossip Girl's' Blair and Chuck suffer throughout 'The Unblairable Lightness of Being'

chuck-ULB.jpgWithin the past week, Leighton Meester and Ed Westwick have both broken off both their real-life and fictional relationships. That's a lot of dumping to keep up with in "Gossip Girl" world.

In Monday (April 12) night's "The Unblairable Lightness of Being," Nate and Serena approach the newly split Blair and Chuck separately in an effort to get the two to talk. Chuck drinks, Blair sulks, and Nate utters an "Oh my god" when he finds out his best friend tried to sell his girlfriend to Jack.

In happier couple news, a pregnant Dorota gets hitched to Vanya. But does Serena rock the boat on her red-hot romance when she slips in a secret meeting with ex Carter Baizen (a.k.a. Meester's real-life ex and newly tapped Captain American sidekick, Sebastian Stan)?
