He's got to have already tried this, but: what does she get if she filters for extreme, desperate, high-intensity passion for comestibles?
That's interesting. The search goes through, but it definitely doesn't get all vampires, and it picks up humans, too. Addy and Blair are not on the vampire list.
"Oh, this silly thing grades on a curve," Addy says.
"Yes. Can you get it to stop? Or at least pick whether you're looking through the remedial or the honors?"
"Well, that depends on how you work, how you think about it, why you have this power instead of someone else or something else. Hmm, I have a process usually but maybe your silly power will let me take a shortcut." She circles him, quizzing her copy about this fellow's style.
He's highly adaptable and loves exploring, but not for the sights. It's for the people that he meets, and for what he learns about the world. He likes seeing things big-picture style as much as possible, and he likes being as equipped as possible to handle whatever the world throws at him. This mostly seems to be in the sense that he should improve, not that he should get cool toys. He should know as much about a situation as possible, understand as many languages as possible, and be able to handle a given situation physically and mentally, and know who to go to for help. This means well-used witch powers and the ability to fight, but also self control, an open mind, and a good idea of what the world's actually like instead of just vague concepts of it.
Once she looks, it's pretty obvious why the power grades on a curve; he's of the opinion that context is highly important when judging people. Writing off an entire culture for being lesser in comparison to another culture is - not exactly incorrect, but short-sighted, and to properly judge something one has to judge it by the circumstances that surround the something too. So his power is being 'helpful' and accounting for the context on its own, at least for vampires and humans.
Also, he prefers black and dark red as colors, has a strong preference for hand-made objects over factory-made objects, eats animals instead of people because he hates the idea of not having perfect self control, and likes playing chess.
"So," she says, "why do you want your power to find you vampires?"
"... Because it's important to know where the people that can kill me are?" he says dryly.
"So you need to find people who are a certain way relative to you," she says. "Not relative to their - category. Have you ever got your power to do anything like that before?"
"... Sort of. It's managed to find me two people that were helpful to me specifically, first try. Not relative to their category. The organ freezing one was for someone else."
"A vampire who can resist the smell of blood so completely he can work as a doctor; he hasn't eaten anyone and his self control is amazing. I went to get help with my eating people problem. I'm as certain as I can be that he was the absolute best person to talk to."
"The exact search I had was for someone that would understand the situation and could help."
"Can you broaden 'the situation'? Someone who will understand the condition of being a vampire, say? There are not that many informed humans."
"... Not exactly." They are getting into something he considers to be kind of private, but witch powers are very personal, so it makes sense. He won't close up and tell her to bugger off. He thinks back, and disentangles the emotions he had back then. "The exact thoughts I had put into 'the situation' was of more than just the condition of being a vampire, but the condition of being a vampire who could not just see humans as food. On account of my power."
"So what does being a vampire, in general, mean to you?"
"Now, I'm a vampire who's pretty firmly of the opinion that I'm just - myself. I have a set of abilities that are different than what they were, and a set of downsides that I need to account for, but I'm whatever I choose to be if I work at it long enough. With superpowers."
"Hmm. Well, vampires in general have all gone through a transition period, and will feel some way about that. What happens if you look for people who have opinions about that sort of thing, like you but not the same?"
