"So here's what I'm putting together," Bella the Vampire Slayer says. "You are some kind of demon-or-something from another dimension, which is why you are stunningly ignorant of supernatural staples; your friend back there apparently turned you, which means you were at least loosely human to start, although I can't rule out 'extradimensional human population raised as cultist sacrifices to insert Old God here' or something fucked up like that; and now you have broken into a library to correct your admittedly woeful education and think this is the correct situation in which to insist on some sort of respectful rules-of-engagement rigmarole that made sense in your original world while the Slayer has a crossbow and you are ash waiting to happen. That about right?"
