Ok.. So I'm watching Serenity for the nth time and it's finally bugging me enough to ask.. Apologies if this has been oft discussed. The Reavers are portrayed as animalistic savages that eat human flesh and are barbaric in every sort of way. BUT They exist on the edge of known space in a "cohesive" armada that sends out scavenging parties for parts, ships and food. It makes me wonder if there isn't some sort of higerarchy of Reavers that are more intelligent than the raiders. Otherwise, why would Serenity have been scanned when it flew by the mother ship. More than that, you have to have some rational intelligence to fly a starship, right? Otherwise, why would the Reavers not feed on each other?
