Finally seen gravity falls not what he seems

Ok who's this I saw the episode of gravity falls with not what he seems I was wondering what the story was all about but now I seen it and I'm blown away I haven't been this surprised since I saw the movie Avatar and now the story is unraveling to become the biggest surprise ever if they do a third season I like to know more about Stan's twin brother but whatever what happened back then is a mystery still so this is what I want to tell and that's all I wanted to know now gravity Falls is the biggest mysterious and coolest cartoon I've ever seen so that's all I wanted to say thank you
