More Facebook conversations between Joe and me:
Joe: How the hell do you keep a barnfull of walkers under wraps for that long?
FM: Exactly! Like none of Rick's group noticed that the barn was locked up? (Of course, Rick's gang is a pretty stupid group of individuals - Herschel was correct in that it's a miracle they have for survived for so long.) And I'm thinking a herd of trapped walkers makes noises - moaning, groaning, what have you - that would be heard out in the quiet country nighttime. But why do you think he's got them locked up? Are they family members/loved ones whom he can't bear to kill? Or are they for some other nefarious purpose?
Joe: It was mentioned that Herschel wanted to deal with the walkers, presumably because he had some issues with violence [Ed.: like not letting his people carry guns]. He probably isn't working on a cure - maybe it's some kind of zombie dog-fighting ring.
FM: *crosses fingers*
