'A werewolf bite can kill vampires,' Elena says as she watches Tyler screaming in agony of his transformation.
It's time for the other supernatural creature to rise on "The Vampire Diaries". Elena, Damon and Alaric take a road trip to Duke University and search through Isobel's research on folklore and paranormal phenomena to see if they can uncover any clues to the mystery surrounding the Lockwood family.
Isobel's former student, Vanessa (guest star Courtney Ford) offers to guide them through the research and ends up getting quite an education herself. Stefan comes face to face with a terrifying new danger in the woods, and Tyler makes a shocking discovery about Mason. "Bad Moon Rising" airs September 23 on The CW.
Executive producer Kevin Williamson said about the tension between werewolves and the Salvatore brothers, "It's in line with all the other sort of mythologies in that if you go back to the beginning of time, wherever there was a werewolf, there seemed to be a vampire nearby and they always seemed to be at odds with each other. We don't reinvent that part of the story line. What it means to be a werewolf and a vampire coexisting in Mystic Falls, the rules are different here and there."
