The finale of Season 2 began awesomely, by showing us where the massive horde of walkers originated from, all the way back in Atlanta. The helicopter from the first episode was flying overhead (don’t know who it was yet), and the walkers were mindlessly following it. As the horde heard Carl’s gunshot from, they followed that, and unfortunately for Herschel’s farm, there were hundreds of them at that point. Rick and Carl were heading back toward the farmhouse after the Shane incident when they noticed the horde of walkers following them. At this point Rick’s quick thinking took them towards the barn, where he proceeded to light it on fire – killing/distracting the walkers. The Grimes Boys escape with help from Jimmy, who pulls the RV up to the barn so they can jump onto the roof, and then stops the thing. Why did he stop the RV after Rick and Carl were on it? I presume suicide. My favorite part of the beginning, though, is that Lori suddenly realizes that Carl is not in his room. This is a running joke, now, because Lori always loses her son. I doubt if Carl even has the room that he is always supposed to be in.
After the fiery barn escape, the whole group teams up to fend off the giant number of zombies attacking them, and they fail. Patricia gets eaten right in front of everyone, as Beth had to be pulled away from her screaming. Who is Patricia, you ask? Otis’s wife… but I Googled that. Why did she get attacked? Because she was a very unimportant filler character, and every time she spoke, everyone fell asleep. Boom.
Hershel being the total bad-ass he is, tried taking on all of the walkers himself. Eastwood style.
