Kristin from E!Online gives us the follow spoiler:
Brad in Memphis, Tenn.: What else can you tell us about the new supernatural creature that appears on True Blood this season?
We can tell you that the creature appears in the June 28 episode and brutally attacks Sookie (Anna Paquin). It’s got a bull head, a half animal, half human body, gnarly claws and is poisonous like a Komodo dragon. And it almost kills Sookie. But Eric and Bill (Stephen Moyer) team to help make her as good as new. Oh, and we soon find out the murdered voodoo lady from the first episode of the season was a victim of this same creature.
