Sophie was a walking truth serum. If she was touching bare skin, she could yank the truth out of you like a loose tooth. I’d spent several unpleasant hours in her company during the Council’s screening process for humans who planned to work with vampires. That’s when I learned that you don’t refer to Buffy, the Winchesters, or even the Frog Brothers from The Lost Boys in front of Council officials. They do not have a sense of humor about that sort of entertainment.
