The one thing that is quite clear from the show (and from what else Pollyanna McIntosh told CinemaBlend) is that the Scavengers are an adaptable bunch who aren’t afraid to cross lines and change tacks if that’s what it takes to survive.
Sure, they live in a junkyard in the zombie apocalypse, but their lots in life don’t seem all that terrible by Walking Dead standards.
We still don’t know too much about the Scavengers other than the facts that they’re led by Jadis, are unafraid to double-cross their allies, and have found a way to not die of tetanus despite being based in a junkyard.
