As with the legacy timeline, werewolves aren't transmittable in the way of like 'The Wolfman' or something. Having the condition be genetic is just makes more sense to me when the content isn't actually horror. If I were using the condition in 'Maho Noir' or something else, I'd be more likely to have it be the curse style lycanthropy... but since ZR isn't a true horror story, I'd rather not have to find ways to hand wave the risks.

Lyn's line about in almost all cases leaves the room for ritual transfer like in the legacy timeline. I'm not sure I'll use it, but the werewolves knowing about it allows for me to not have to retcon it later if it's needed.
