A Supportive Mech
As the Promethea grew hotter both inside and out, the living mech made a critical decision.
She disobeyed her orders.
She disregarded her own principle that she should do whatever it took to protect her battle partner.
She allowed Venerable Isobel Kotin to proceed with her madness even though it looked as if she was about to kill herself!
A normal AI or machine intelligence would have never thought of defying explicit orders as well as long-standing customs and policies.
Mechs were always subordinate to their mech pilots and anyone else in a position of authority over them. The mech industry always treated mechs as tools that had to obey their instructions without fault.
It was unthinkable to many people that mechs could wilfully disobey their instructions and instead make their own decisions, especially when they were in defiance of their human masters!
