This is a bit tongue in cheek, but reading this passage got me thinking: Fiore sounds an awful lot like that guy. You know, the one that everyone rolls their eyes when you mention? The guy on the internet or at the workshop who is loudly and verbosely telling you that everything you are do or think is incorrect. And will find any and all reason to not practically demonstrate their skill in a free play.
You can almost imagine the frustration of Fiore's contemporaries: "uh huh Fiore, how many duels with sharp swords have you won? Five, really? But you won't train with us or show us anything of your Art? Really? We'll I find that all very hard to believe..."
