1) What are people using for drugs? Since nobody can import heroin, cocaine, or opium, they can't get those outside of a dedicated farming operation and even then they can't really grow in the states. Synthetic drugs would be outside the reach of most people in the Loss due to technological and supply limitations. Tobacco was produced in what is now the Recession and they won't export it if they can even grow it. The only things I can think people would be able to get or make is pot, mushrooms, things to huff, and alcohol. Are a new breed of dealers creating new types of drugs from what's left?
2) Are the vectors or casualties smart enough to dig? If someone was underground in a bunker or tunnel would they dig down or run for an entrance? If not would a collapsed mine or a landslide be a minefield of trapped casualties?
3) Would a psychopath-turned-vector attempt to deceive others into coming closer instead of shouting at them to flee? I can see a person running is away from a group a casualties towards a taker group, shouting for them to help, only to tackle one of them when they run over. Maybe an Abberant's voice sounds much clearer than the other infected and it can still form sentences?
4) Would a cult dedicated to infecting others, upon their turning into vectors, intentionally slash up and augment their mouths and hands to better transmit the Blight? I can see a taker getting grappled by a Casualty, confident his chain mail will protect him, only to find out someone drove a bunch of needles into its hands as his shoulder begins to burn.
5) Would feral people like Paddywhack or people too young to remember the Crash be bothered at all by reminders of the old world? After a while, would people be unaware the Recession even exists or would they see it as a mythical place?
