'True Blood,' Season 4, Episode 7, 'Cold Grey Light of Dawn': TV Recap. Antonia has successfully entered Marnie’s body and in a Voldemort-meets-Quirrell sort of way, uses her human host to try to achieve her ultimate end: the destruction of every living (er, you know what we mean) vampire around. Her first step is to take mind-control of her Inquisition-era torturer and rapist, Louis. She forces him to kill Bill’s lieutenant and finally fulfils the vampires’ fear that humans will be able to control the dead. Of course, Marnie probably wouldn’t have been moved to call upon Antonia if Eric hadn’t provoked her in the first place, but we’ll put that aside for now as we understand plausibility is not a chief aim of this show.
