This was one of the better episodes since season 1. This show might be finally turning a corner?
The ginger's backstory was brief but good. So his family left him because they were terrified of his brutality? He's a man who needed a mission. He accepted mullet's story hook, line, and sinker because it's what he needed. Still doesn't explain everyone else buying into such a stupid story, but whatever - it's reasonable to assume that people will do some pretty irrational stuff in a zombie apocalypse.
So next up should be rescuing Carol and Beth, I guess, and then who knows from there.
