The Governor is most certainly dead!! Come on, he put a bullet in her daughter without even batting an eye. She saw what a monster he was, there's no way she didn't kill him. Also, who let's her kid play in the mud, alone, out in the wild, without being close enough to defend her if something happens? Unfortunately, that little girl died because of her dumbass mother!!
The little girl putting a bullet into the carpet muncher's girlfriend was pure genius!! Loved the fact that Carol taught them to survive. If not, Tyrese would be dead!!
Kickass is fine. Unlike the comics, she will have survived the last battle at the prison. My guess is that Daryl has her.
It's obvious that there was a plan in place in case they were to be attacked again, whether with walkers or anyone else. I assume they have to have a rendezvous point. My guess would be where they were at the end of season 2, right before they find the prison. Just a guess.
One last thing, poor Hershel is now just a zombie head!! I bet you didn't think about that!!
