There’s supposed to be a “time-jump” in season 4....how much of a jump is not clear. Perhaps the issue with these new people will be resolved when the show starts back up.
Yep, and I hope it isn’t much of a jump. I want Herschel with us, LOL.
I think it will follow the comic, where they had the first attack from the Gov, repelled him, and it was quiet for awhile, allowing them to grow gardens and live life for once.
However, the number of undead grow outside the fence and the Gov’ returns with a bigger vengeance than before....
The time jump between season 3 and season 4 is expected to be more than 3 months but less than 1 year:
