Later a middle aged woman is spotted in a car with a teenage girl. The woman has a handgun and makes a gesture to tell the characters to move away. Later we see the same car driven by two men, no older woman, but the teenager is in the back. And it's like we don't know who those men are? It could be her uncle and father or it could be much darker...

There's a bit where dozens or even hundreds of survivors who have managed to last a few days converge on a stadium where they are going to be rescued. They all have guns they point at each other hesitantly. Zombies keep running up to them and they all shoot the zombie then keep pointing them at each others. Eventually so many zombies are drawn by the gunfire they're all fighting at once. There's multiple moments where humans accidentally shoot each other in brutal crossfires because they're inexperienced and panicking.

There are lots of zombies in this season. But most of the conflict is human on human. With chud survivalists lead by an ex-cop. Basically nearly every dies completely avoidable deaths and precious resources like shelter from winter/fuel/food/weapons are completely and utterly squandered. They had enough for everyone and could have survived together but selfish US individualist brainworms kills them.
