I haven't felt so good for Subaru in some time now. Echidna is going to be quite a treasured ally, even if she's not particularly helpful from a "just watching" perspective.
I vaguely remember that one of the evil dudes who chopped up the post-whale-hunting-party claimed to be the Archbishop of Greed. In that case, all those so called Archbishops and Cultists don't have anything to do with direct orders from witches at all.
