Vampires aren't supposed to be real. They're just something Bonnie likes to fantasize about. Victoria never gave it a second thought about whether or not they were real. To her they were just an overly exaggerated thing Bonnie wished were real. That was until Bonnie told her there was a way you could become one and that it was so easy Bonnie couldn't resist signing herself and Victoria up. Officially signing her death warrant without her knowing.
