My nit pick is why are they worried about scratches and bites when they’re already infected.
If I were Virgil, I’d be the one legged man at the ass kickin contest.
They don’t all know they are infected yet.
And in addition, they are infected now in such a way that they turn if they die.
If they get a bite, they will turn while they are still alive, in kind of a elongated zombie-approaching hangover.
Scratches and bites from Walker’s still kill, they always have, which is why they’re deathly afraid of being bitten or scratched by a Walker. The only change is that now they know that those scratches and bites aren’t what cause someone to rise again.
