Carrying on from the comments on blood borne diseases and vampires.
If a vampire drains a drunk or a 'coked up'drug addict - would they too begin to exibit signs of intoxication? Would a vamp that fed on, say, heroin addicts risk addiction themselves (if only second hand as it were)?
Very silly thought.
I had this vision of a werewolf (in human forn) being killed and 'turned' by a vampire - Scene: Turned werewolf (in bat form) flys over pine woods, the full moon emerges from behind thick cloud, flying bat trys to turn into a wolf in mid-air (with all the aerodynamic qualities of a big dog), falls into the wood - So what happens when the vampire/werewolf hybrid finds itself impaled on a tree?
