But one big theory on Twitter is that if an Original becomes human, so will the rest of his or her bloodline.
As proven by Finn’s death — and Sage’s and Troy’s — if an OV dies, every vamp sired by the Original and his or her followers will bite the dust, too. It’s not clear if that rule applies when a vampire becomes human.
Rebekah (Claire Holt) desperately wants the cure, both for herself and to make her brother Klaus (Joseph Morgan) more vulnerable. “If Klaus takes the cure he will simply be a werewolf, doesn't matter what it means for his hybrids because.. well.. you know ;)” Joseph Morgan explained to a Twitter follower.
