Using as few words as possible to communicate, Jadis’ community takes supplies to ensure their survival without directly engaging with others, and they’re also shown to be ridiculously resourceful, an attribute definitely honed by living in refuse.
The dialogue-lite Whisperers also don’t start shit with anyone who doesn’t cross their borders, and what’s more resourceful than using walker skins as camouflaged clothing?
Because of how playful showrunner Scott Gimple and comic creator Robert Kirkman are with porting comic elements to TV, it’s hard to tell if all the similarities between this new group and The Whisperers are genuine in that respect, or if all of it was conceived specifically to mess with fans.
