Gossip Girl: Gasp! What Did Chuck Do? Here's a Clue

Creepy window display shows upcoming scene, sources spill on what will go down

We all know Ed Westwick's Chuck Bass is one pretty ginormous Basshole, so nothing he could ever do would be that shocking, right?

Wrong!

Apparently, Chuck is doing something so heinous on the CW's Gossip Girl, it's worthy of a big ol' (ominous!) window display in NYC's Meatpacking District, and it certainly appears to spell trouble for Blair (Leighton Meester). So what does Chuck do?

Spoiler Alert:

I'm hearing from insiders that Chuck "sells out Blair" in an upcoming episode of Gossip Girl. And by the looks of things, it's happening fast and it's going to get ugly...and dangerous!

As you can see from the photo above (taken by Racked NY), the words "What Does Chuck Do?" are emblazoned on the NYC storefront of designer Matthew Williamson, who crafted a dress Leighton will wear in next Monday's episode. According to the CW, Gossip Girl costume designer Eric Daman designed and installed the window last week. It features a Blair mannequin on the floor surrounded by mysterious men in suits and fedoras.

According to Racked NY: "The most important part of the display is the TV screen broadcasting a future Gossip Girl scene. The entire sequence is in black and white. Blair is lying in bed in the Matthew Williamson dress...She gasps at the site of a fedora-wearing man peering through her window. All of a sudden, the suit army storms the door and takes Blair. The next shot is of Chuck running through the door. He falls to the ground and grabs onto the dress for what looks like dear life, sobbing."

What does this all mean? Piece the clues together in the comments below, say a little prayer for Blair, and know this: Hell hath no fury like a Queen B with a designer dress torn!
