The finale of True Blood

I wasn't able to watch True Blood until last night and it was worth waiting for. The whole maenad was finally resolved with Sam the one who kills her. What's with Eric selling V for the Queen of Louisiana? Is Eric the one behind Bill's kidnapping? What a great cliffhanger for the end of the season! The series is definitely different from the books but I view them as a separate entity. Now I have to wait for next summer. I guess I can watch season 1 again then season 2.
