remmber this is a different setting than in the comics. shane should be dead right now and there would be more than just the one black guy. but I can't wait to see if they keep what's in the barn. from the comics to the show.
The implication is that they will. In last night's episode Herschel told Rick there was no need to go towards the barn and would consider that they could stay if they "followed the rules." Also, why else would he insist they disarm unless something else was going on around the farm?
