The puzzle is beginning to take shape.

We don't know quite what's going to go down between Blair, Chuck and Jack on Monday's all-new Gossip Girl, but we do know Blair supposedly wears a Matthew Williamson dress ... which we now see her picking out in a newly-released sneak preview clip.

So what did Chuck do? Your guess is as good as ours. But it doesn't look good.

Also not looking good? Jenny's prospects for not getting killed by fans, based on another new clip. The first sneak previews we posted showed her making a move on Nate. She continues her pursuit after the jump ... we shudder to think how this ends.
