Well, the heart eating seemed to enhance her hold over them. Besides, kink for the sake of kink is her thing. She seems to feed off of it.
What I don''t get is Sam. How hard would it have been to say "The killer's name is Mary Anne. She looks exactly like Michelle Forbes, only sluttier. She's a Maenad, an immortal supernatural creature with hardcore mind control powers. She's been forcing people to engage in kinky sex orgies and human sacrifices since time immorial. She came her to get revenge because I rejected her years ago. I'm immune to her mind control because I'm a shapeshifter. Daphne was a shapeshifter, too, she was the pig that Andy saw. She worked for Mary Anne. The bull wasn't a bull, it was just a Marry Anne in a mask made out of a bull's head. And yes, she does have claws. Andy seems to be immune to Mary Anne's mind control, too, I don't know why. I strongly suggest that you issue a kill on sight order for Mary Anne right now, and get some rocket launchers because I'm not sure that bullets will actually hurt her. Call in the national guard if you have to. And quite frankly, the safest place for me is not jail, but several thousand feet in the air. Unless I get sucked into a jet engine, but you get the point. She can't fly, I can. There is no way that she can catch me out there. In here she can just mind control you into killing me. And don't ask me if I expect you to believe that. Vampires are real, Sookie can read minds. Yes I expect you to believe that. Look. See. I just turned into a dog. "
