Just a few observations that come to mind. It is impossible to defend this show. I can not believe the scripts. This episode reaches a serious low not because of the acting but the writing is atrocious with nothing that resembles intelligence by the cast. Nick refuses to kill the psychopath Troy even when he realizes the guy has sent a gigantic herd of Walkers directly at the ranch. Nick can however crack Jake -the only person the tribe trusts- on the head causing a bite and death. Then Nick not only refuses to kill him but turns his back to Troy and expects him to help save the people Troy was trying to kill. Even more nuts is that Troy probably will because you know that will totally make sense.
Then there are the people at the ranch. Their best plan with a horde coming? Hand out some guns and hide behind the RVs and hope they pass! Well that doesn't work so it is time to pack all the people into a shelter from which there is no escape. Here is a thought why not hide the vulnerable people and use the RVs as a caravan to lead the dead away. I know Walking Dead is about how real people would behave in a apocalypse and not some super hero type but cmon both groups are survivalists. I blame myself for continuing to watch.:0.
