What did you find most shocking about the world the writers had created in the two-hour finale?
I was blown away when Davies was killed.
All the sudden the guy who was the threat, he was just a pawn as well.
Theres always a bigger picture and that blew my mind.
Halfway through the finale, it seemed like all the problems had been solved.
And then…the Shepherds rolled out the destruction of humanity.
Not a murderer, but maybe a martyr is what he wanted to be.
Oh no, I think [Jackson] thinks his dad is completely out of his mind.
It just reinforces what a nut he was in Jacksons mind.
I mean, those arent easy things to get.
Thats a dangerous world that someone would have to live in, almost like a hunter or ahuntedworld.
And if he is on the forefront ofsomething…what is that?
Now that grown-up Clementine has revealed Mitch is still alive, whats next for the Animal Avengers?
I think they need to save humanity, and theres clearly also a threat with these razorback hybrid animals.
Its going to be unlike anything else on TV.
