"Is that the taxonomy here, nobody's both good and interesting?"

The vampire looks kind of lost and kind of impatient. "Being the Slayer's probably pretty interesting."

"Mkay. I'm gonna rig up an experimental good behavior enforcement system for you before I let you go. I expect to continue to be available to provide ethically sourced blood. Is animal blood nutritious for you, out of curiosity?"

"Never tried it."

He hands her a cup.

She sniffs it and makes a face. "Gonna go with no."

"Okay, how about this -" New cup. Shelf stabilized human blood.

She makes less of a face. "What's this?"

"O-neg."

"Human, though?"

"Yeah, just shelf stable, or it would be if it were sealed up. I don't want to be making a lot of trips to feed you and anybody else I catch so I might want to just leave a stash of this around and replenish it every now and then."

"It'll do."

"Taste it and make sure?"

She tastes it. "Yeah, it'll do."

"Cool." He starts designing a vampire-good-behavior system on his computer. "I never got your name."

"I'm still tryna pick one, actually."

"Do you have a working title?"

"I was gonna pick between Tate and Talon and Shadow. What do you think?"

"Ooh, I like Talon."

"There we go, then!"

"Nice to meetcha, Talon, I'm Cam. I'm gonna put at least one tracking device in you and a blood-detecting diagnostic object in your mouth which will inform me when you are snacking and I'm currently undecided whether unauthorized snacking should just kill you or if I want the responsibility of hunting you down to avoid the risk of equipment failure, what do you think?"

"I think putting explody things in people is more evil."

"Does that mean you're in favor?"

"Yeah!"

"Gosh, I guess that settles it!" Design design design. "Okay. Diagnostic thingy leaves your mouth, that'll signal the explody thing and notify me - any trackers leave your person, so will that - diagnostic thingy detects a blood response and you aren't in the depository I will make and stock for you, that'll signal the explody thing too - debugging in progress - do you have a phone, I could buy a phone in case there is any problem with this and you need software updates?"
