Yes, and I'd wholeheartedly agree if it weren't already mentioned to be a legitimate curiosity of a main supporting character. Ishida can no longer gloss past that factor. Even if just in an interview, it needs to be eventually revealed how Ghouls came to be, even if in-universe, they we're just always there. Clarity of some sort.
