The Twilight series is overflowing with binaries which are necessary to create and build the story line. The binaries include natural/unnatural; good/bad; student/teacher; reality/appearance and the most obvious, masculine/feminine.
Bella falls in love with Edward in a natural way. She is intrigued by his mysterious, bad boy persona and finds herself head over heels for the guy that remains a mystery to everyone. Edward on the other hand is initially attracted to Bella by the scent of her blood and finds himself obsessing over protecting being with the girl of his unnatural dreams. This is the binary of natural versus unnatural forms of love.
In this series it’s as though Bella is a student, entering what she always thought was a fictitious world. Edward and Jacob are her teachers trying desperately to win her love by having her understand the risks and threats of being involved with the other ‘creature’. By teaching her the ways of the Vampires and the conflict between them and the Werewolves they are getting Bella more and more involved with every secret that’s exposed.
Edward and Jacob appear to be completely normal young men with great looks and stature, when in reality they are casing the truth about their inhuman qualities. Reality showcases the real them, Edward a sparkly, blood sucking vampire who never sleeps and Jacob an oversized, hairy werewolf. The use of this binary opposition displays a sense of enigma and presence of occult.
Bella is pure, innocent, human and a fragile female. Edward and Jacob exude masculine qualities and of strength, muscles and mystery. These qualities of contrast come together in the books and movies to create a collision of two completely different worlds into a love story that prevails.
Without binary oppositions Twilight would be lumped together with all other love stories, boy meets girl, boy fights for girl, girl falls for boy. Binary opposition plays a huge part by creating the Twilight series as we know it today, a unique love story.
