Forget the Kool Aid. Bill Compton is drinking the blood. And it's making him do some crazy, seemingly traitorous things.

On last night's new episode of True Blood, Sookie's ex brought Jessica into The Authority picture, while he also appeared to convince Eric that he ought to switch allegiances. But did he really?

Perhaps we'll find out on next Sunday's "Sunset." Watch the official HBO trailer for the upcoming installment now:

Elsewhere, fans can look forward to the following developments:

• Sookie relies on a faerie elder to look deeper into her family's past.
• Alcide reconnects with his father.
• The military exploits a video of Russell and Steve Newlin.
• Sam and Luna grab a ride into The Authority.
