Sam Kills Maryann (Season 2, Episode 12)
The villain of season two was the maenad Maryann, who had come to Bon Temps after being romantically burned by Sam. Hell hath no fury like a woman scorned, indeed: maenad literally means "raving one" and this Greek creature lashed Sookie; cast a spell over the locals that turned their eyes black and forced them into raucous, orgy-filled parties; and threatened Tara's wellbeing all in the name of seeking revenge on Sam. The shifter's nobility gave way to his animal instinct when he ultimately realized it had to be him that killed Maryann. This inner conflict – just one of many faced by the show's supernaturals – would come into play when his parents and shifter brother reappeared, and again when Sam fell in love with a fellow shifter whose ex happened to be the leader of the local wolfpack.
