You know, I find it pretty remarkable--and yet, logically fitting--that SV seems to have no trouble with preaching and attempting to convert everyone they encounter in-quest to Catholicism, despite the sheer prevalence of atheism among SVers.
It's fitting, though, that a bunch of atheists would be both logical and pragmatic about the whole thing, and be happy with the progress being made from a utilitarian perspective. The world of Bloodborne is horrific, bleak, and terrifying. With the nature of the plague, it's extremely hard for them to have faith in their fellow humans, so giving them faith in an omnipresent, benevolent, and compassionate god is honestly quite heartwarming. In a world where the only church is the perpetrator of eldritch horror and corruption of all kinds, converting everyone to Catholicism is a massive step up.
Also, Ebrietas is adorable. I expect Djura to meet her, and following an explanation, go "I'm too old for this shit."
Speaking of Djura, we really need to warn him and the others back at the Chapel ahead of time to expect Ebrietas, so they don't shoot her on sight or something.
