Just three episodes to go on Gossip Girl, and many mysteries still to be solved.

Next Monday, "It's Really Complicated" for Dan and Serena, who host a Thanksgiving feast ... in December. The episode was supposed to air a week earlier before Hurricane Sandy pushed everything back, of course.

Picking up where last night's Gossip Girl episode left off, the apparently back together Derena decides to invite only their closest friends, but everyone seems to have their own agenda for attending the dinner.

Meanwhile, Dan has written his next expose, but faces a tough decision on whether to publish it, and Chuck begins to spiral out of control after being bested by Bart, leaving Blair searching for a possible solution.

Check out the promo for next Monday's installment and comment below:
