A new title and casting call for True Blood’s ninth episode is out:
True Blood episode 6.09 will be called “Life Matters” and a few co-star roles are being cast, including a crazy vampire, a sickly vampire, and a male vampire who is the sickly vampire’s progeny.
Source: SpoilerTV
The sickly vampire call makes me think that perhaps the human war on vampires might include the design of a blood virus that could affect vampires. That or perhaps Hep D makes a reappearance on the show (it was mentioned in season 1).
All the casting calls for season 6 are on this page:
