Should be pretty obvious, but the promo has spoilers for episode 11, so don't watch unless you've seen it. Description of it below the cut.
Promo summary: Everyone is rubbing it in Waterford's face now that he's in jail. June seems to be suspicious about why Serena went off alone with Fred.
Also Chris Meloni posted some behind the scenes photos of his last scene on the show.

They did it, I was almost out but they pulled me back in. Probably the most satisfying episode of the series so far. I know there are at least 3 of us still watching it.
