Yeah Hershel told them there was a fence surrounding the farm which is why they considered themselves "safe" compared to the town or other areas.
Nope its not just you, they are very different characters. At times in the first season it seemed like she was going to be like the comic but then the more she was influenced by Shane I think they had better chemistry so I can see why that idea was scrubbed.Is it just me or does Andrea's character seem very very different from the comics? In the comics she was basically in love with Dale, still wears his hat, enjoys alone time in a tower with a sniper rifle. To me she seems like a passive person who just goes with the flow. In the show she just seems like a ****** off person who wants to start **** with people. I wonder if she will wear the hat????
