Everyone's going gaga over the segg and I'm here worrying abt the sick kid. Y didn't the father let jinwoo see him?! So suspiciousssss dammnn is the kid turning? And then that other person sneaking in the storage room ... shxt, everyone's suspicious

The child might be dying or already a zombie and they're hiding his condition from Guwon. The lady was probably stealing extra medication/supplies to help the dad. But if that's the case, then they can't lie about him having a cold forever.
I have a feeling that Guwon wouldn't hesitate to get rid of the kid if he was a danger to the village in some way
I'm outta here
