Orangibberish encountering the preschool children in Episode 4. At first, it's a subversion of Improbable Infant Survival, but then it gets much more horrific when you put together a child's psychology and the virus' effects. Children can be easily susceptible to fear, and we know that the virus turns fear into rage. Would pre-teen children be much more violent than other demographics?
no zombified adults are seen or implied to be in the preschool, did they abandon the children to their fates?
As a halfbie, Nam-ra’s hunger probably wouldn’t be satisfied by eating regular food, even if it was available in post-apocalypse Hyosan. But what was an available meal for her? The corpses of her former classmates.
during the drones flight, as it lingers near the gate we can see other abandoned and crashed cars that are pointed towards the gate, Ji-mins parents likely wherent the only ones who tried saving their kids from the school.
at the same time during the drones flight we get 2 more examples, one is a student who hanged herself, comfirmin there was at least one other surviving student who ultimatly chose to end her life, and another being a barricade on one of the doors of the same classroom window she was hanging from.
the bodies that are still being eaten by the zombies.
during night shots, lights from other classrooms can be seen, implying other survivors.
Fridge Brilliance
Why does Gwi-nam stick with a knife to kill zombies when a long-distance weapon would be more effective? As pointed out by Tumblr user thelitdirge, he doesn’t want to avoid having to fight the zombies-he relishes in killing them and is willing to put himself at risk just to do so.
You can actually see which students became zombies, the zombie actors also play students in pre-outbreak scenes.
