Gossip Girl producers Stephanie Savage and Joshua Safran preview next week's episode in the video below, and from the looks of it, there's a ton of stuff going on.

It's the 18th birthday of Eric, the last Gossip Girl minor. The theme is childhood, since Eric didn't have one. But that's just on the surface of "While You Weren't Sleeping."

There's the mystery of what Damien blackmails E to do, which comes to a head at the party. Meanwhile, Blair struggles to multitask, as we've seen in the promos.

Responsibilities at work, plotting schemes ... even a queen gets overwhelmed. Finally, Chuck enlists Nate's help in winning Raina back. But what's his motive?
