[serenity/firefly] A question about reavers.

How are reavers so organised? If they were that aggressive wouldn't they have turned on each other while floating in space. Not forming a fleet, maintaining space craft and sending out raiders. Also why is no one doing anything about them.

So, reavers only go full aggro in the presence of outsiders. They're violent assholes in general, but the pure LETS KILL EVERYTHING only comes to surface when they are dealing with non-reavers. 

As for why no one is dealing with them, it was believed that they would just die out after a generation or so, and thus the problem would solve itself.
