Wasn't there one - something Ashes? No, Burnt Offerings, I think. Where there's like, a pyromaniac vampire and at one point this lady sets a vampire on fire and Anita instantly knows that this lady knows a lot about vampires - such as, that they're flammable - and she must be part of that anti-vampire church or cult or something. And she explains to one of the policemen that vampires catch on fire. And he's all "Damn I didn't know that". There's a college program about the biology of these things, but no one ever thought to tell the GODDAMN POLICE that vampires CATCH FIRE PRETTY EASILY? This really strains credulity.

Like, who the fuck wouldn't/doesn't know that? It seems pretty goddamn basic to me. I think Laurel just needed Anita to know lots of things about vampires that other people don't, but couldn't be assed to come up with something that would make sense for that purpose.
