And with Alexandria, The Hilltop, and The Kingdom all without any firearms (besides Rick’s recently returned revolver), it will be much harder to dispatch a large sum of walkers.
Having zombies once again pose a threat to the survivors would be a great way to make the back half of Season 7 interesting.
I can practically hear the dramatic Walking Dead music already.
We already know that the communities are planning on (finally) revolting against The Saviors, and having the dead further complicate this mission would be a great way to keep the stakes at an all time high.
