Despite Chuck and Blair's breakup on last week's episode, many fans remain hopeful that the Gossip Girl couple will, as Mr. Bass predicted, find their way back to each other in the end.

Still, don't expect his new girlfriend to be welcomed with open arms.

"We have another guest star coming on, which is amazing," Jessica Szohr says. "She starts to date Chuck Bass, which is exciting because everyone wants Chuck and Blair together. This someone throws a little loop in their relationship, or throws everyone, actually."

Any theories about who Chuck will date, and what said "loop" is?

Other Gossip Girl news and notes:

• Katie Cassidy is signed on for 11 episodes total, so it looks like Juliet will leave the show ... but not before some truly "great stuff before she goes."
• Sam Page's Colin is gone, too: "There's no plan to return as of yet, but the door's certainly open since we left it on a nice note," the actor says.
• There's nothing in the works for Jenny and Nate. Hopefully ever.
