He nods thoughtfully.

"So the next traditional part of the turning experience is giving the new vampire their first - meal." He closes his eyes and hisses slightly. "In the form of about half a dozen victims, neatly tied up and waiting for when the vampire finishes turning." His voice begins taking on a very passionless quality. "I'm fluent in over forty languages, and I have difficulty describing being faced with that without any kind of forewarning. Especially after three days of torture, in a whole new body with a whole new set of instincts, including the super speed to immediately do the very first thing your instincts tell you to do without giving you time to reconsider or try to fight it. And it is difficult to fight it. It's like resisting a feast when you're starving, or a breath of air when you're suffocating, or water when you're burning from the inside out. It's all of them, all at once, and more."

"That sounds very unpleasant."

"Yep. Worse, drinking someone's blood is - let's go with rather incomparable, and leave it at that. Drinking human blood makes it harder to resist drinking it later, because instead of just imagining what it tastes like, it's known in agonizing, perfectly memorized detail. So that neatly sabotages every vampire from the beginning, confronting them with both the prospect of being a murderer and having to resist that. To add to it, they have a whole new circle of friends that treat eating people as normal, natural, just a part of how the world works, the humans are all just meant to be food, and anyway they'll all die eventually anyway. It's such an easy idea to cling to when your entire life has been ripped away with you and you've woken up one day to become a monster.

"So trying to come at the problem through morality is - not at all viable, frankly. Not for the vampires that are already out in the world, anyway."

Nod.

"Quenching the unquenchable vampire thirst would go a long way, but not the entire way. It would prevent accidents and some portion of the deaths, but vampires acquire the self control to resist eating every human they come across for simple practicality, and that the vampire government will kill them if they don't behave themselves well enough to plausibly hide their existence from humans."

"I'll have to talk to your sister to see how easily I can quench the unquenchable thirst."

Nod. "She hasn't had long to work at it, admittedly, but she'll definitely help how she can."

Nod.

"Complicating things is the secretive vampire government. They do a number of very useful things, such as keep vampires from turning children and creating newborn armies, keeping vampire society from collapsing into chaos, that sort of thing. Which is wonderful and useful. But they have also made it illegal to tell humans about vampires without then either killing them or turning them, and predictably as a group have exactly zero regard for human life. Worse, they have magic powers of their own that lets them stay on top, not all of them nice and friendly. One of their leaders, Aro, can gain someone's entire set of memories by touching them. They have a number of other witches - the term we call people with magical powers - that give them various advantages against other vampires that might like to rule the world."

"...They also sound like a problem in need of solving."

"They are not nice people, but I think leaving vampires without a governing force would be worse than leaving an amoral one in charge," says Blair diplomatically.

"I'm aware of the principle."

There's a story there that Blair is studiously not going to ask about.

"All right, just making sure."

He nods. "Yes."

"So in other news, if you could please not wander around telling people about how vampires are a thing, I'd appreciate it."

"Yes, of course."

... Yeah he's starting to see how this guy is compatible with his sister.

"Thanks, I appreciate it."

He nods.

Smile.

"Anything else I can help clarify?"

"Not that springs to mind immediately, no."

"All right. Want to talk to my sister, then?"

Nod.

"All right then."

Zip, and away he goes to find his sister.

She is standing perfectly still, carefully experimenting upon a rock with transmutation.

"Hi," she says, changing it back to its original composition and dropping it unceremoniously on the ground.
