Though infuriatingly frustrating to sit through, this episode did what it had to do to forward the plot (minus the Kingdom, curiously absent this time, must be Second Unit filming): foment the seeds of discontent within Alexandria. I'm pleased that a few characters were never happy with the centralized control of Alexandria's weapons, though the one stash and one scavenged pistol seem like too few for even Rick's crew. Once again our band of zeroes learn nothing from past mistakes (or history).
And why Michonne is still with Rick after this is thoroughly beyond me.
