It’s no coincidence that this comic-sourced tactic is showing up now, since The Walking Dead has hinted at this inevitability with Father Gabriel’s unidentified illness.
And what about survivors who have had fresh wounds grabbed by walkers’ flesh-eschewing hands?
What about the injured Alexandrians who walked through that swamp full of infected walker slime?
Also, wouldn’t Lucille already be an infection-delivering machine after being used to kill so many other walkers, or is the amount of walker gore indicative of the seriousness of the situation?
