Angela Kang’s comments to EW point toward The Walking Dead finally forcing the survivors to adapt to a lack of resources without any lucky discoveries of weapons caches.
Now, The Walking Dead has admittedly tackled the concept of low resources in the zombie apocalypse in the past, with characters siphoning gas and going on missions for food (or booze, as the case once was).
Apparently they’ll even finally run out of cars to siphon gas from on a regular basis in Season 9!
They may struggle for a while, but then they have enough bullets and gas to wage war on each other.
