as with Edward Cullen and the other vampires in the Twilight series, they can move faster than the human eye can follow, and are much stronger than humans. Also as with the Twilight vampires, each vampire generally has its own unique gift or ability, such as Essie's gift of mind wiping, or Marty's gift of telekinesis, or Merrill's ability to read minds. Although the vampires are immortal, this series states that the older they grew, the weaker and slower they become, until they are eternally locked in a paralytic state. Although spelled differently, Wrenfield High is clearly named as a nod to Renfield, the madman who wanted to become a vampire from Bram Stoker's Dracula. Also, Dwight Frye, Malcolm's father and the school security guard, is clearly named after the actor Dwight Frye, who famously played the character in the classic 1931 film version of Dracula. Although Dwight is referred to throughout the series, his only appearance is at the beginning of the second episode There's a New Vampire in Town. According to actor Adam McDonald, who played Nick McAllister, he was supposed to also appear in the episode Dads and Monsters, where he becomes possessed by an evil vampire, but due to an accident involving the actor playing the character, the story was hastily re-written so that Nick becomes possessed instead. There are several continuity errors surrounding the character Karl. According to Malcolm Frye in the episode Little Sister, he was wearing his old Wrenfield High school jacket when they had their run-in earlier which he posted about on the internet. Yet in the actual episode where that occurs (A Grave Matter), Karl was in fact jacketless. Also, in the episode The Summoning, it is stated that Karl had killed at least two people before being recruited into the Mansbridge Experiment, namely his best friend and his high school crush, but according to Marty and himself in the episode Blood Trip, he has only one killing to his credit. Another error, particularly concerning the character Karl, concerns Wrenfield High, the school he attended prior to becoming a vampire. Its name, and Karl's and Malcolm's descriptions of it, suggests is it a public high school; however, when Karl's younger sister, Amy, visits Mansbridge on a field trip, she is wearing a school uniform and Malcolm says she lives in a dorm at Wrenfield, suggesting it is a private boarding school
