I was joking for the most part.
Thing is Lucas, despite swearing fealty to the church and being in Seena's care, is looked down on as a monster by nearly everyone, and he'll most likely be wary of hunters since they're the ones most likely to take the whole 'cursed monster child' thing too far and kill him anyway, but if Lia happens to have proven herself different and showed him some form of kindness in the past then that won't be an issue with her.
Also, for the record, Lucas isn't carnivorous, he's pretty open minded about what he's given to eat, vegetarian or otherwise, and perhaps fortunately so, cause I think in a setting like this one can't afford to be a picky eater.
