"Wow, okay. You're Castiel! I totally read about you in the books." Since he's already aware of them, it makes things way simpler to just come out and say she's read them. "Whoa, hang on, that means whoever's running the show here can pull in angels?"

That's worrisome. She seems a little more relaxed now, which is good, and gives him a bright smile.
