Bella slips into the school by a side door; she just saw a thing and she thinks she's seen it in a book before and thinks it's supposed to be mostly harmless but before she wakes Giles up over probably nothing or kills a likely neutral demon she wants to check.
And she pushes into the library.
Mark reports back, "Found them. The kidnapper has your Giles tied to a chair but otherwise mostly unharmed. How shall we proceed?"
"My Giles," snorts Bella. "Uh, I'll call Charlie." She has her phone now. She calls Charlie. "Where in the hotel are they?" she asks Mark.
"Thanks." She relays this to Charlie, and then the call's over. "So, this is kind of an awkward question but do you need directions to the butcher shop your brother has been raiding, and if you do not already know where to find it what have you been eating?"
"When I arrived in this world I was in a room full of ominously chanting robed cultists. They deprived me of my senses by magic and I killed a lot of them anyway. Their 'god' was very impressed and offered to make me his immortal consort. I declined. He decided to make me his immortal consort anyway. When I woke up, I fought him, won, and eventually managed to kill him by cutting his head off. Then I ate some leftover cultists. Between that moment and a stop at the butcher's on the way to the school earlier tonight, I didn't eat."
"Oh. Okay. Well, kindly restrict yourself to the butcher's shop and I'll give you a pass on the cultists, although I'm not sure you needed the advice with your soul emulator as described."
Shrug. "You can drop us off at the butcher's. Sometime soon we'll want to be driven to an airport but that's not a project for tonight, I don't think."
And Charlie shows up and goes in with Bella to arrest the fellow with Giles tied to a chair.
"D'you mind sharing a vehicle with a coupla vampires, I said I'd give them a ride to the butcher shop but you probably need a lift too."
"The vampire who was locked in the house with me turns out to be Ray Gun Vampire's twin brother and they are both waiting outside."
