I kinda stole this from The Walking Dead's facebook page, but for those of you who saw the season premiere, would you have stayed with two on the highway or gone in the woods to look for sophia....and why?
I'd send andrea to the woods with the gun, if any walkers heard it, it'd be difficult to find where it came from (like the church bells) but did you see how she mutilated the walker that broke through the bathroom door? If she had a gun then, that'd be all 7 shots being fired and the herd would have came back.
It won't matter if they couldn't pin point the exact location of the gunshots, with that many zeds, all they would need to know is that the shots came from the woods. They would swarm the whole area and it would be diffucult as hell to escape them all. Grimes had a problem dealing with two, now imagine hundreds.
