Quick questions about vampires:

Does the general population know that vampires are among them?  

If so, how do they feel about that (do they hate them, begrudgingly live with them, hunt them down, flee in fear?)
If not, do vampires have very obvious supernatural characteristics that would make them stand out as a species or do they pretty easily pass for humans if you don't know what to look for?

I'm just trying to figure out how Jack (or anyone) should react when they see something vampirey happen.

@RedXIII [Jack] id say that vampires are not common knowledge. Dracula hasn't even been published yet[/quote]
