You gotta feel sorry for Luke. I mean, he's basically got the mind of a 7-year old, what with his "memory wipe", and has spent most of the last 7 years learning how to function as a human being. And yet every one lambasts him as if he should know everything about everything, and not taking into account the fact that his immaturity is a result of the fact that mentally, he IS immature, as well as being locked up in a mansion with little outside contact. Ok, Jade, Tear, Anise and Ion have an excuse (he
does have the body of a 17-year old, and it can be difficult to wrap your head around that level of amnesia), but Guy and Natalia have no excuse, since they're partly responsible for teaching him to function again!
Yea, it's a bit of a rant, but this is a textbook case of
Poor Communication Kills. There should be a law that if you keep someone out of the loop, then they do something they wouldn't have if they'd been IN the loop, berating them leads to horrible death. Preferably by monkey attack.
