Avoiding attention is exactly what he aims for with any of his wards.

I didn't notice where these details had been noted, sorry. But, Waver here can play nice with a variety of methods and adapt accordingly. I just realized now that I've had a chance to focus some on RP that, as a Vileblood, this is a project that Waver would keep his eyes on in case he needs an assist in the future. He hasn't developed any habits involving blood thirst-- but he has taken to chewing as a stim, and he's well aware of public opinion about this particular blood type.
