The popular theory is that Ardbert is one of the 14 shards of our soul, and he surrendered his aether to us so we could defeat Hades. Did Ardbert putting us from 7/14 to 8/14 really make us that much stronger? I'm confused, because the implication of the following cutscene where Hades sees us as an Amaurotine is that our soul is now "whole". What's going on?
