So I happened to notice a MAJOR plot hole. Maybe someone can explain it.
First Darryl kills Fat Joey. Turns out he was a demolition expert that was setting up a booby trap to kill a huge horde of walkers.
The walkers come, but Neagan doesn't have anybody on lookout making sure the trap works?
The trap had a shit load of dynamite, but nobody investigates when only one stick goes off?
Finally, Rick and Michone attack the horde with a steel cable stretched between two cars. Not only would this be almost impossible to pull off (they never agreed on how fast to go, but somehow match speeds perfectly), but the cable is going to cut most walkers across the chest or waist. That will slow the horde down, but it won't stop it. It would have easily overrun their entire world by the time last night's episode took place, yet we only see two walkers in the entire episode?!!
It seems like the writers have something epic planned or they no longer give a fuck about the show.
