their smell would cover hers
it's funny how in later seasons, zombies lost all sense of smell, (probably because of ageing? but new zombies were the same I think)
The smell didn't matter at all, if you just wore a dried up zombie skin head mask. Then you could be part of the herd. They could hide right next to a zombie herd passing through in the ditch. You could get really close to a zombie from behind.
Zombies basically just turned into extras in that series. Poor fellas got nerfed hard.
Congrats! You passed all your tests with flying colors.
