Blair and Chuck decide to go for one drink to unwind from the near-death experience, and end up crashing a bar mitzvah. A carefree dance scene set to the oddly spot-on "Rolling in the Deep" leads Blair and Chuck to reunite (wink wink) in a nearby room while Louis waits for her. Um, it was two episodes ago that he manhandled Blair! Whatever, their relationship is "complicated," as Blair tells Chuck on her way to cut Louis loose.
But this is not their happy ending: when Chuck encounters Louis still waiting for Blair, he gives them his blessing and tells Blair that she deserves her fairy tale. Chuck thinks he might be growing up, and he lets Blair go. Or does he? The episode concludes with a positive pregnancy test in Blair's trash can.
