Looking through his family Bible, Bill realizes that he still has descendants in the area, the Bellefleur family, and sets up an anonymous legacy. When he’s summoned by his maker, Lorena, he stashes his computer in Sookie’s hidden vampire retreat. He briefly surrenders to the will of his maker, becoming her lover once again, but she soon reveals that her true intent is to acquire the database. When seduction doesn’t bring the results she wants, she turns to torture. Sookie kills Lorena during Bill’s rescue, and she angrily questions his feelings for her. Bill continues to profess his love and explain the situation with his maker, but he soon leaves on a research trip for the database. Upon his return, he discovers that Sookie and an amnesic Eric have become intimate. Still trying to win her back, Bill takes Sookie back to his house after her kitchen is set on fire, ready to care for her. He reacts badly when he walks in on Sookie and Sam kissing at Merlotte’s, and he soon brings in a date to retaliate. After helping Sookie by staking her cousin’s killer, Bill offers his services should she need help settling her cousin’s estate. Although she declines, he joins her on her trip to New Orleans. After she is attacked by Jake Purifoy, Eric forces Bill to admit to Sookie that she was an assignment from the queen. Devastated, Sookie sends him away. He saves her from Jade Flower at the queen’s spring party and shows up at her door to wearily tell her that he genuinely loves her, but Sookie is unable to forgive him.

Bill continues seeing Selah Pumphrey while Sookie moves on, but he remains adamant in his love for her and watches over her. He arrives at her house the night of the takeover, worried that several vampires have suddenly lost touch. After the arrival of Victor Madden, Bill agrees to the terms of surrender, but not before telling Victor that he would willingly die for Sookie. He proves his words when Sookie is kidnapped by fairies Lochlan and Neave. Bill and Niall track her, and Bill kills Neave, who manages to bite him with her silver-capped teeth. Sickened with silver poisoning, Bill still manages to stand in front of Sookie when Breandan’s forces arrive, killing Breandan himself with Sookie’s trowel.
