I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
At page 85, two very important people are having a conversation way, way out of human hearing range. But not out of a Mecha's hearing range. They just put the newbies into the Mecha's, and let them roam free where they could hear - and Matt did.
Matt, who, as I suspected is amazingly adapt at using Mechas. Way more than anyone else at the beginning, and so much so that his superiors are agog

and even the father of the Mechas - the man who made it all possible - has taken a personal interest in Matt.
Yup, Gary Stu fantasy, which is annoying. This fail in logic is also bothersome. Either have the conversation elsewhere, or turn off the extraordinary senses of the Mecha, no? Or, seriously, you don't have a room that has some kind of mechanical white noise? (Or something that would make this a private conversation?)
Because, as Matt thought, they haven't let this news out. So what if Matt sells it to someone or tells his fellows cadet? Seeing as the government seems to be keeping the fact that a world of their has fallen to the Corsairs, their enemies, I'd think they'd take more care to keep that information away from prying ears.
