I've been watching TWD over again from the start, and something in Season 4 has me curious....
If you recall the flu epidemic in the prison (the first to succumb to it was Patrick), it seemed that the walkers outside the fence were exhibiting symptoms...mainly bleeding eyes.
At the time the episode aired there were all sorts of theories about the source of that flu strain. Rick's pigs. The rats Lizzie was catching to feed to the zombies at the fence. Karen's cough.
Now, think about the backchatter at the start of Fear the Walking Dead.
All the reference to a flu outbreak, a veritable Chekhov's Gun All the resultant speculation amongst watchers that this "flu" is actually the zombie virus spreading.
It's starting to look more and more as if the "flu" really is the zombie virus. What really has me wondering.....years into the zombie apocalypse (TWD Season 4) it's still sweeping through the living and one would think that seeing as everyone is already "infected" with "the virus" that they wouldn't catch it again which leads me to suspect the flu/virus is mutating. After all, this time it seems to be affecting the zombies....I'm mean in a harmful to the zombies way, obviously it's already turned them.
So, will there be further changes in the virus? Will it become more lethal to human the next time around? Will it end up destroying walkers it infects*?
*Not sure if infect would be the right term. Contaminate?
