So what's the explanation for when you get KO'd? I mean if you're just out randomly and get ko'd Im sure it can get explained that someone drags you back or the Aether teleports you back or something but what about in quest battles?

I mean is Ifrit really ok with you just getting KOd he doesn't want to kill you or whatever? And furthermore when you do instances the exact same scenario plays out even if it's incredibly unlikely that it would happen twice

If there is no explanation then I have a fun little theory. When you get KOd in a important battle the Aether or the Echo sets back time and erases your memory of the event, thus the exact same scenario plays out but since you've experienced this fight in the past even if you (your character) don't remember it, so it makes you better at the fight (AKA the Echo Boost)

If I'm wrong though and it is explained I'd love to know
