So, let’s get back to the farm and Hershel, at some point during the show Hershel and his family became key players. Hershel was very upset with the fact the people could be cured and they were still there. He was really hanging on to that hope. Probably the last positive contribution Shane made was in advert, he shot that woman. It made Hershel realize the walkers were not people, they were something different. That allowed him to face reality. And of course they had the scene where Hershel was working through it in his own way. Which I believe was the first time, that somebody was actually shot as a living person. Then you see the humane side of Hershel, when you see somebody was trying to shoot at them in the bar. And then the kid they had saved, Shane used for bait to set up Rick. And long story short, Shane exits the show. Rick initially shoots him and then he comes back as a zombie and Carl takes care of him. Then the whole herd shows up. Carl and Rick make it back to the house, well to the barn, and set it on fire. Everybody starts running except for Hershel, who stands there shooting endless bullets from his shot gun. Which seems to be the biggest issue for people watching the show ha-ha! More people were more caught up with the endless bullets and not so much with the zombies eating people.
