I liked how Michonne used two of the Gov. men as her 'pets' in last nights episode.
I think it's a cool idea but the way it works is completely ludicrous.
Why do all the other walkers ignore her just because she has two around her? Something magical about the ropes I guess, because it's not like they don't still lunge after any other human even though there are walkers nearby.
Also, why do the two that she dismembers as protection go docile? They don't have any brain function to realize they are useless, so they should still be attempting to eat her rather than just standing there.
