9. 'The Vampire Diaries': Elena Vamps Out (Season Four, Episode One)
Elena Gilbert never stood a chance. Just as Bella Swan's fate was inevitable in the Twilight saga, it was only a matter of time until The Vampire Diaries' Elena turned to the dark side after nearly four seasons of playing footsy with the bloodsucking Salvatore brothers. When mortal Elena seemingly died in a car crash, it begged the question: How could the show lose its leading lady? Indeed, Season Four's opener revealed she had Damon's blood in her system, leaving her with a choice: feed on humans as an immortal or die. And, really, who would choose death over an eternity in the middle of a hot-brother sandwich? Adios, daylight! Hello, newly birthed vamp. Death has never been so becoming.
