Gossip Girl is back!!!!!!!!!

Last night's episode of Gossip Girl was back to being the show that I fell in love with...almost. There was one brief moment of the old Chuck (yeah!) only to be replaced by the Chuck with a conscience (boo) but otherwise the entire episode left me wanting more (and more and more). For a full recap check out EW.com (here). I just wanted some feedback about what happened at the end. Brief summery..Serena fell for Poppy's boyfriend in Spain (Gabriel I think). She rushed home thinking that she had married him (she didn't) and he followed her. Gabriel seemed really into Serena until the end when we saw him arrive back at Poppy's place. WTF? Who is this Gabriel and what is he doing to the fair Serena? Are he and Poppy just f***ing with her for laughs or is it more sinister than that? Now here is the big question...is Georgina involved? Any thoughts, ideas etc? We all know that Georgina is coming back this season (next week in fact), is this the reason?
