Vampire diaries and Viktor

I was reading the comments on Nina's Foia video and saw someone mention that apparently in the show Vampire diaries, the character Viktor says that in order to kill an enemy, you have to stab them 17 times and decapitate them. Otherwise they come back. Now I've never gotten into that show myself, so I don't know how accurate that is. But I think it was really interesting and thought we could discuss that here. She seems to base all her life and lies on movies. It's pathetic.
