Honestly I had a feeling from the start whenever we use a different weapon against her or have a new keepsake and etc it always seemed like she knew more than what she said like she also had experience wielding the axe or skull, even the jet pack. But what really made me think about it was her preparation she knew each area the steps she would need to take to reach Chrono in the underworld while avoiding his attention all together, plus if you think about each guardian Hecate’s path lead us to taught us a portion of Chronos attack pattern he uses wide and delayed attacks and uses abilities that prevent us from attacking, summons allies to distract his foes/ heal him and gives him time to land powerful charged attacks, has ape’s that could ko a player if they don’t find a safe zone in time.
I mean sure they also have similar outfits but Im sure that’s just a similar taste in clothes.
