OMG!!!I just seen the comic-con extra video!!!spoiler!!(dont read my Q in less seen video they gave at comic con!!)

In the book series Sookie is with Bill, but Bill leaves her for his maker, Lorena, leaving sookie heartbroken. Eric & Sookie grow closer over numberous near death experiences & they fall for each other. If they are following the general outline of the novel, Sookie is most likely with Eric in the bed

I also think it is probably Eric. However, the show is a little different from the book and it looks as if Lorena takes Bill by force on the show. I am very curious to see what you have seen. This show, and the book, just keeps getting better and better.
