I had another question on everything that lead up to that. I wasn't paying much attention at the start, but weren't Carol, Rick, and Jerry all in the same car as they were t-boned? Fast-forward to your encounter and the saviors have Jerry captured but Carol and Rick are off roaming free. It's possible I just skipped a scene or two, but I have no idea how it got to that point.
The one thing that I think they dropped the ball on in a big was was the clearing out of the herd at the sanctuary. They said Eugene figured it out and implied that it was related to loud music, but the specifics weren't clear at all. His remote control plane was shot down by Dwight. The saviors huge speaker truck was destroyed by Daryl. What other big sound devices did they have that Eugene had to dream up?
