I was so focused on the ninja/hooded figure I didn't even notice the armless zombies until Cat mentioned them! Duh! I had to go back.
Well, they are not only missing their arms they also had their lower jaws removed! I guess if you can't grab/scratch or bite you sorta get complacent/depressed and stop trying to feed. And really, if this badazz hooded figure already relieved you of your arms and lower jaw and has you in chains...you probably don't want to aggravate her by trying to attack.
Having these two walkers on a chain sort of sends out a message to other walkers, as well. 'Mess with me and this will be your fate.'
Lori is not only a waste of oxygen she is as annoying as hemorrhoid.
