At the very end of Monday's "The Debarted," we saw Chuck Bass visiting his father's grave on the anniversary of his death. But he wasn't the only one there.

We were led to believe that the mystery woman who exclaimed "Charles!" was in fact his mother, who is in fact alive. Where can we expect this to lead?

EW's Michael Ausiello has the latest in his column today ...

Q: Who was she the woman standing over Bart's grave on Gossip Girl?

A: First off, the grave stalker has a name, and it’s Laura Harring (The Shield). Second, yes, she will reveal herself to be the Bass family matriarch when Gossip Girl returns in March. Something about this makes my impostor antennae go up though. Call me a whore for stunt casting, but if and when Chuck’s mom returned from the dead, I always imagined producers would go for a big name. Who’s with me?

Laura Harring will play the mother of Chuck on Gossip Girl.
