On tonight's episode of Gossip Girl, we'll hopefully find out whether or not the mysterious woman - Elizabeth Fisher - is indeed Chuck's (Ed Westwick) mom or just the one of the crazy women that Bart Bass played with like she claimed. We'll also learn if Jenny's (Taylor Momsen) descent into Damien Hell will go as scheduled, or will parents Rufus (Matthew Settle) and Lily (Kelly Rutherford), after discovering a bag full of pills, be able to stop things in time?

Elsewhere, Dan (Penn Badgley) and Vanessa (Jessica Szohr) are struggling through the awkwardness of dating other people, all after the fall-out stemming from the similarly awkward revelation when Serena (Blake Lively) was in the hospital before Gossip Girl went on break. Finally, Serena and Nate (Chace Crawford) are doing the nasty everywhere. At least they're happy.
