This tells us that Gilbert was definitely a Yharnamite (he turned into a beast and immediately recognizes the player as a Hunter), but that he also suffers from something beyond normal blood ministration (he makes reference that "what inflicted [him] was incurable").

By this do you mean that Gilbert was born in Yharnam or that he has become a Yharnamite, which you describe as a person more receptive to blood healing, through receiving blood ministration for his illness? He describes himself as an outsider and talks about how the town gave him hope, so he's likely a foreigner like the player character, though the fact he has a Flamesprayer suggests a former association with the Healing Church of some kind.

I'm working on my character by the way, just... struggling to make a random Yharnam citizen seem interesting. I'm making a (false) paleblood as well.
