At the beginning of the episode when Rick is showing Michonne and Carl how to build a snare, he explains that you do it in a way where there's a funnel so the animal has only one way to go until the end where the trap is hidden. This is the exact way the people at Terminus draw in survivors. They guide them down the train tracks until they get to Terminus where the trap has been laid.
That's so FIIIIRRREEEE
If this doesn't have racist jokes in it, they can keep it. Plus, this won't be good as the other ones, sad to say, so get ready for a disappointment.
