Gossip Girl is back for its final season, and this week we find out what everyone has been doing all Summer. Dan's back to writing, Blair and Chuck have resumed their romance (sort of), and Georgina is back in the mix. However, no one seems to know what Serena has been up to, so the premiere revolves around the gang trying to find out exactly that. There's a surprise wedding that's not what it seems, along with a hookup that's more creepy than scandalous. Without further adieu, let's get to the first OMG moments of Gossip Girl season six now!
