We've seen promos and a sneak peek from the episode. Now Gossip Girl executive producer Joshua Safran gives us a preview of "The Princesses And The Frog."

In addition to the complications brought to Blair and Louis' romance by his mother, and Nate getting caught in the middle of Chuck and Raina, Joshua promises:

• Vanessa still being on the outs with ... well, everyone (shocker)!
• Rufus getting a job (and even more amazingly, a storyline)!
• Something "very big" happening. One of the biggest things ever to happen on the show, in fact. It will "change the course of several characters forever."

What the preview below and comment with what you think that is ...
