Spoiler about Vanessa that biotch (Spoilers)
I think the idea that Vanessa brings back Georgina could be true as I can't see any of the other characters calling up Georgina !
wasn´t there another spoiler about her and revealing dan's book or something? maybe this is what the ggsss spoiler's all about.
One thing -- Charlie is not real Charlie. It's fake, hired by Serena's aunt for something evil. She is Ivy, and we saw her in next season.
