The final season of "True Blood" saw both Bill Compton and Eric Northman infected with the lethal "Hep-V," a biological weapon designed expressly for the eradication of vampires. Bill had recently giving up his status as vampire messiah and had made peace with his upcoming death, while Eric Northman fell into a deep melancholy. Interpersonal drama ensued, and Bill and Sookie expressed their feelings for each other one last time. Bill revealed his desire to die and wanted Sookie to use the last of her faerie powers to kill him.
This action would also have the side-effect of making Sookie a regular human, and granting her a "normal" life. Sookie eventually complied, and ends up driving a wooden stake through Bill's heart, granting him the "true death" that he longed for. The series ends with a pregnant Sookie with a new, unrevealed boyfriend, surrounded by friends and family — both vampire and not.
