Alexander Skarsgard revealed to TVGuide:
“The feelings are still there for both Eric and Bill. The attraction is still there, but they’re preoccupied, and so is she.” Instead, look for Bill and Eric to team up while the vampire world begins to both expand and collapse in the coming season. “The guys have usually tried to kill each other and now suddenly have to learn to become friends and protect each other and work together.”
That sounds like Sookie will have her own troubles to deal with, while the boys step into the ring with the Authority.
