Mark (vampire hunter)

Mark is a vampire hunter whom you know very well. You are a vampire. You mostly fed on animals, but you did occasionally take the odd human. You have a very complicated relationship with Mark. You occasionally gave him information on where to find vampires and what their weaknesses were, but he would occasionally also try to kill you whenever you decided to have a human dinner. Last time, you told Mark that if he tried to kill you again, you would bite him and turn him into a vampire... and look what he tried to do a week later.
